Thank you so much for your videos ... So far i am excited af to watch them and learn to build a 2D game demo..!!! I made a parent gameobject for the patrol points and added the script to the child enemy to make it work.
So well explained, my brain is so messed up I can't handle 90% of the tutorials out there. The way you explain it is perfect. Glad I found this channel. Looking forward to seeing what else I can learn. I'm currently doing Brackey's Gam Jam, and making my first game! Trying to do as much as possible to practice.
That's awesome! Game Jams are one of the best ways to learn. When I got started, I found that repetition was really important, so mini projects are great as you get to re-use a lot of the same code elements. Good luck with the Jam!
Hi, thanks for uploading such helpful videos, I just want to ask once you in the enemies sight and they start to follow you, will they follow you forever or is there a distance where they will go back to their route?
At the moment, the enemy will not go back. That said, in the Update method, under your if statement for isChasing, you could add a line of code that checks when the enemy is outside your chase radius (the same line of code you use to start the chasing, but with a > sign instead of a
That's works perfect.....you should make this entire series into a Udemy course, I paid and done a two different courses and yours was x10 better. You really explain very well.
I've got a few problems in it, first one is the enemy which is continuously jumping to the end of point 0, and the second is it is not coming to left side and staying at right end point by continuously hopping.
If it is hopping, that almost always means it cannot reach the patrol point. Try moving the patrol up or down a little to make sure it came be reached. That usually resolves this problem.
Hi, my enemy is having a problem where he moves to one of the points and just stops there, did i mess up the code? public class MovimentoInimigo : MonoBehaviour { public Transform[] patrolPoints; public float moveSpeed; public int patrolDestination;
// Update is called once per frame void Update() { if(patrolDestination == 0) {
Usually that means that the enemy is not able to get close enough to the patrol point to trigger a turnaround. While playing, try switching to scene view and move the patrol point up or down a little. Chances are a little adjustment should get everything working.
@@migs_2559 Alright, well that was worth a try (it's usually the thing that gets people). Taking a look at your code, I think the issue may be some misplaced curly brackets. At the moment, once you switch your destination, you are missing a closed bracket. So now, it will only check if you have patrol destination #2 IF you have patrol destination set to 1 (which will never happen). While you are adding the fix, it is often helpful to include some debug statements. For example, if you add some Debug.Log("reached destination 0"); at the point where you detect destination 0, you can find out which parts of your code are firing and which parts are failing to be exectued. I hope that helps!
@@NightRunStudio you were correct! I missed a curly bracket, thank you very much! I'm doing my graduation project based on a 2d game and this helped me a lot on the enemies i'm putting in
If you are flipping using localScale, you need to use the negative version of whatever you set your scale to. So if you have changed the scale of the object to something other than 1, -1 wont work for flipping. In that case, you could just multiple it by -1 (so it will just become the negative version of itself), or hardcode in the negative version of whatever your scale is set to. Hope that helps!
i've got a few problems with this the first on is that it only goes to one direction and can't go to the other.That only happens when i set the patrol destination to 2 but when i set it to one or zero it starts having a panic attack The second one is from the other video about enemy chase.The code doesn't work
I'm happy to take a look at your code for the enemy chase. As for the freak out, that usually means that the enemy is unable to properly reach one of your patrol points (often, it is set too high or too low and the enemy can actually get to it)
@@NightRunStudio i fixed the freakout i will also send the code using System.Collections; using System.Collections.Generic; using UnityEngine; public class Patrol : MonoBehaviour { public float moveSpeed; public Rigidbody2D rb; public Transform playerTransform; public bool isChasing; public float chaseDistance; public Transform[] PatrolPoints; public int patrolDestination; // Start is called before the first frame update // Update is called once per frame void Update() { if (isChasing) { if (playerTransform.position.x > playerTransform.position.x) { transform.localScale = new Vector3(1, 1, 1); transform.position += Vector3.left * moveSpeed * Time.deltaTime; } if (playerTransform.position.x < playerTransform.position.x) { transform.localScale = new Vector3(-1, 1, 1); transform.position += Vector3.right * moveSpeed * Time.deltaTime; } if (Vector2.Distance(playerTransform.position, playerTransform.position) < chaseDistance) { isChasing = true; } } else { { transform.position = Vector2.MoveTowards(transform.position, PatrolPoints[0].position, moveSpeed * Time.deltaTime); if (Vector2.Distance(transform.position, PatrolPoints[0].position) < .2f) { transform.localScale = new Vector3(1, 1, 1); patrolDestination = 1; } } if (patrolDestination == 0) { transform.position = Vector2.MoveTowards(transform.position, PatrolPoints[1].position, moveSpeed * Time.deltaTime); if (Vector2.Distance(transform.position, PatrolPoints[1].position) < .2f) { transform.localScale = new Vector3(-1, 1, 1); patrolDestination = 0; } } } } void FixedUpdate() { } }
@@randomperson.0-0 So... I think your problems are stemming from the fact that you are comparing your Player transform to your player transform. What you want to check is the difference between your player's transform and the enemy's. Otherwise, the chase conditions will never be true.
@@randomperson.0-0 No problem. As for the enemy only going to one destination, I can think of 2 reasons: 1) Make sure that your code is comparing the enemy's position to his desired position 2) Make sure that he can actually reach the destination (that it's not too high or too low). You can check this by firing a Debug.Log when his position is == to the desired position. If this fires, you'll know he is reaching it, if not, you know he can't reach it).
I'm having problems. When my enemy reaches patrol point 0, it just stays there and doesn't turn start moving to patrol point 1. My code is exactly as it is in the video.
This is usually a problem with the way things are set up in Unity. My first suggestion would be to put a debug.log statement in your OnTrigger method (right at the top). That way you can make sure that your enemy is recognizing when it reaches the patrol point. If that’s working, one other common problem is that people often mix up the patrol points and put them on the wrong sides of the enemy (so when it reaches one, it knows to go to the next one, but can’t because it’s in the wrong direction). The debug.log is a good place to start though, as it should help you diagnose where the problem is. Let me know if it is still giving you trouble after you try that. Cheers!
Hello and thank you for the video :) I have a weird problem that when I add the script made in this video to the character it stops the player damage from working.. Soon as I take it off though the player damage works as normal though!
That's pretty strange, since this one only deals with movement. I guess it depends on how your damage script works. Feel free to pop into my discord and share your code if you want. I'd be happy to take a look.
That probably means your sprite’s pivot point isn’t centred (so it is flipping based on an axis that is off to one side). If you click on you sprite in the assets folder, the go to your sprite editor, you should see a little blue circle on the sprite. Make sure this circle is in the centre, as that is the point from which you will flip. I hope that helps!
@@NightRunStudio Hi, mine has this exact problem but the pivot is centered and the z is the same on both the parent and sprite. Is there anything else that could possibly resolve this issue?
@@sillytoonss Is your x position the same on the child as on the parent? One thought is that your parent may be flipping, but if it is centered at a different x position than the child, the child would appear to teleport.
i have a problem where the enemy goes to the other side of the map, then starts doing the patrol, also for some reason he no longer has a collision, meaning he doesnt collide with anything anymore and goes out of bounds, any idea on the fix?
This is usually an issue to do with parenting. If the enemy, or the patrol point is a child, it will add its parent's position to its own... As a general rule, make sure that the parent of the enemy and of the patrol points has 0, 0, 0 as its position. Then the children should behave better. Hope that helps!
Hi! I have a problem where my enemy only moves to the left, even when i assigned it to the patrol point on the right it still goes left. And also it only moves to one direction. I tried putting Debug.Log in the if(patrolDestination == 0) and the console shows nothing.
It definitely sounds like your enemy is failing to switch destinations (especially if your debug isn't printing to the console). This could be a number of problems. Does your enemy continuously move left, or does it move left and then get stuck once it gets close to your patrol point? If it's the latter, then it is usually a case of the enemy getting close to the patrol point, but not actually being able to reach it. This can be fixed by moving the patrol point to a more accessible location (often it is set too high, or is in the ground so the enemy can't get there). You can test this while in play mode by going into scene mode and moving the patrol point at runtime. If that doesn't work, feel free to paste your code and I can take a look. Good luck!
@@NightRunStudio This is the code, my enemy is also not able to go back and forth between those patrol points. What i understand is that the enemy does not even recognize the patrol points? That being said i tried readjusting the patrol points in terms of height and distance from each other. Also thanks for the early reply using System.Collections; using System.Collections.Generic; using UnityEngine; public class MonsterMovement : MonoBehaviour { public Transform[] patrolPoints; public float moveSpeed; public int patrolDestination; // Update is called once per frame void Update() { if (patrolDestination == 0) { transform.position = Vector2.MoveTowards(transform.position, patrolPoints[0].position, moveSpeed * Time.deltaTime); if (Vector2.Distance(transform.position, patrolPoints[0].position) < 0.2f) { patrolDestination = 1; Debug.Log("Reached patrol point 0"); } } if (patrolDestination == 1) { transform.position = Vector2.MoveTowards(transform.position, patrolPoints[1].position, moveSpeed * Time.deltaTime); if (Vector2.Distance(transform.position, patrolPoints[1].position) < 0.2f) { patrolDestination = 0; Debug.Log("Reached patrol point 1"); } } } }
@@ahmadzufar1112 The code looks good. To solve this, I will need to know what your enemy is doing? Does he move left forever, or does he move for a while and then get stuck? The fact that your debugs are not printing tells you that the enemy is never reaching the patrol points. What might be helpful is to add a debug right under the MoveTowards lines. Something like: Debug.Log("Distance to patrol point = " + Vector2.Distance(transform.position, patrolPoints[0].position); this code, should constantly tell you how far the enemy is from the patrol point (that way you can see if it is actually counting down and where he is close to the patrol point or not).

@@NightRunStudio I do not understand the part with transform.position and when you need to use methods like MoveTowards and and Distance. I guess it does take some time to learn... How long did take for you to learn C# ?
I had been coding for about 6 months when I started this channel, and about 3 years now. I still keep learning stuff all the time. The trick is to keep working at it(which it sounds like you are!). MoveTowards and Distance are helper functions that Unity provides to keep us from having to type more code. As with most things in coding, there are often many ways to do any single task. I chose this one for the video as it requires less code, but there’s lots of way to go about it.
That's strange. The easiest way around this is to destroy the enemy when it runs out of health (Destroy(gameObject), but if you don't want to do that, you may need to turn off the patrol script. (Feel free to pop into the discord server if you want to get into details).

@@faizalaliapriyono1096 Okay! It's definitely a bracket problem. The coordinates for you Vector2.Distance should be in their own set of brackets, and the comparison (the < .2f) should be outside the brackets. Right now, the code isn't sure what to do with the less than sign. It should read: if(Vector2.Distance(transform.position, patrolPoints[1].position) < 0.2f) this way it can find the distance, THEN compare it to .2f. I hope that helps!
I love your tutorials but this one did not work. I dont know what ı am doing ı tried every thing but it does not work. So if you can reply to this commen ı wil share the info of the situation.
Feel free to give me some more details (or to pop into Discord for easier back and forth). That said, a common problem in this video is that the patrol point needs to be set at exactly the right height so the enemy can actually move to it (if it's too high, he will gyrate back and forth underneath it). Additionally, some people parent the patrol points (to clean things up), but then miss the point that the new parent has it's own set of coordinates. Now, when they enemy tries to find the patrol point, he adds the parent's position and the patrol point's together). Anyways, thought those might help, but feel free to give more details if not.
I am having a problem. The enemy moves but when it reaches a point it just keeps moving whitout stoping. I have tried changing them or adjusting the height but nothin works. Here is the code if it helps: using System.Collections; using System.Collections.Generic; using UnityEngine; public class EnemyPatrol : MonoBehaviour { public Transform[] patrolPoints; public float moveSpeed; public int patrolDestination; // Update is called once per frame void Update() { if(patrolDestination == 0) { transform.position = Vector2.MoveTowards(transform.position, patrolPoints[0].position, moveSpeed * Time.deltaTime); if (Vector2.Distance(transform.position, patrolPoints[0].position) < 0.2f) { transform.localScale = new Vector3(1, 1, 1); patrolDestination = 1; } } if(patrolDestination == 1) { transform.position = Vector2.MoveTowards(transform.position, patrolPoints[1].position, moveSpeed * Time.deltaTime); if (Vector2.Distance(transform.position, patrolPoints[1].position) < 0.2f) { transform.localScale = new Vector3(-1, 1, 1); patrolDestination = 0; } } } }
Nevermind actually I mare it so that the points move with the enemy so it would never reach them. After i realized the scale was weird but i maneged to fix it somehow and it works great. Thanks for the tutorial!
Probably the easiest is with a collider set to trigger that you put in front of the enemy, then in the ontrigger method, if the collision object is tagged as ground you apply a new velocity to your rigidbody so the enemy jumps.
While using that system you have to create a points in hierarchy main fork for each enemy, so its VERY BAD idea to do it like that. What if you have just 10 enemies? For each you create 20 patrol points in main tree...
I hear you. I definitely wouldn’t suggest this for games where you have large levels. This is more aimed at beginners, who appreciate the visual approach to setting patrol points. But your point is taken. If you have much more than ten enemies in a scene things can get untenable.
@@NightRunStudio Thnx friend, so what about the idea to create a video with a really good system? I didnt found a good one for 2D, so this content could be really unique and it really helps a lot of peoples do less mistakes even at the start of their gamedev way.
I’ve been thinking about doing just that. This was one of my first series, and I’ve got some ideas to rework these early videos. I feel like we could make this system more effective while maintaining the beginner-friendly nature. Based on your comment, I can see there’s a need for it.
SO I have a very odd problem. My enemy weak point just falls off and lays on the floor once they start to move and I have no idea why. They still hurt me but I have to find the invisible weak point on the floor to kill them now. Any tips on how to fix it?
Did you put the rigidbody back on the parent object (and remember to hook it up in your inspector?). If that’s not it, it might be time to try putting some debug.logs in your code to test which lines are running and which are not being executed.
Hello thanks for the tutorial!! I got a problem, in my case is for a 3d game, I don´t know why it´s wrong: I put some Debugs to see if it works and they are always running the same time, (both ifs) Also I try to move the points like you said to others in the comments but It didn´t work. using System.Collections; using System.Collections.Generic; using UnityEngine; public class EnemyPatrol : MonoBehaviour { public Transform[] patrolPoints; public float moveSpeed; public int patrolDestination; void Start() {
Alright, so I'm pretty sure your problem comes down to a misplaced bracket. (Man, I hate those things sometimes! :) In the video, you may notice that the if statements contained the patrolDestination checks are fully self-contained. In your code, the if(patrolDestination == 1) line is actually WITHIN the same logic that checks if (patrolDestination == 0). To fix, you will need to have TWO closed brackets after the line that sets your new destination: patrolDestination = 1; } } That should help to keep the logic for each destination separate. Hopefully that solves your problem. If not, at least we fixed one problem, and you can let me know and I'll take another look. Cheers!
Is the weak point on your parent object, along with the script? If so, they should be moving properly. I usually try to keep physics (rigidbody and colliders) on objects that are NOT the sprite-that way the sprite doesn’t get separated from the rest of the object.
That sounds like a problem with your scale on the enemy’s transform component. If you have changed the enemy’s scale to something other than 1, and then use scale.x to flip the enemy, it can mess up the sizing. For example, if your x scale for the enemy is 3.2 then when he flips it will need to be -3.2 I would start by checking those values.
@@niveditaph8778 So, it will be important to make sure that when the enemy turns around (when he reaches the patrol point), you set his x value to -2.5 (not to -1). That would cause shrinking.
If he bounces up and down, that almost always means he can't reach the destination point. Adjusting the point should help. That said, you could also add a Debug.Log("hit destination point"); that goes off when he hits the patrol point (that way you can know for sure if the enemy is actually reaching it.
@@TheFortnitePacifist If there was more than one that would totally do it! Thanks for sharing your solution--I'm sure others will find it useful down the road.

My problem is that my sprite Starts going to Patrol point zero, but doesn't stop and keeps going, heres my code if I did something wrong public Transform[] patrolPoints; public float moveSpeed; public int patrolDestination; // Update is called once per frame void Update() { if (patrolDestination == 0) { transform.position = Vector2.MoveTowards(transform.position, patrolPoints[0].position, moveSpeed * Time.deltaTime); if (Vector2.Distance(transform.position, patrolPoints[0].position) < .2f) { patrolDestination = 1; } } if (patrolDestination == 1) { transform.position = Vector2.MoveTowards(transform.position, patrolPoints[1].position, moveSpeed * Time.deltaTime); if (Vector2.Distance(transform.position, patrolPoints[1].position) < .2f) { patrolDestination = 0; } } }
This problem usually means that the enemy can’t quite reach the patrol point. It is often fixed by just lifting or lowering the patrol point a tiny bit.
Hmmn… sounds like a problem with the setup in Unity. The enemy should always move toward a patrol point (hence the MoveTowards function). If it is moving past the point and keeps going then it sounds like it is targeting the wrong thing (as it will always move toward its target). Other than checking the Unity setup, I would also put in some debug.logs. For example I would put some under the if(Vector2,Distance statement… I suspect it is not firing, but if it does it would at least eliminate the idea that the enemy is moving to the wrong target.
He definitely should :) If you want to give some more detail, I can help you trouble shoot. Or you can pop into my discord server and share your code for feedback. discord.gg/6TBz62sV
Hi im begginer in unity and i was doing your script but it didn t work i check if i have it right and i have but my enemy is moving but not to the points can you help me pls?
So here's the thing: I designed this to be highly visual (so you can see the patrol points very clearly), but sometimes, it runs into trouble if the patrol points are placed at locations the object cannot reach. Sometimes, just moving the patrol point a little higher or lower fixes the issue. That said, I'd also be happy to take a look at your code if you want to paste it here.

@@toustik5161 Your code looks good--so it will definitely be a problem in Unity. I suspect that the issue probably has to do with a parent object. In your hierarchy, do you have a parent object that your patrol points are children of? (Probably an empty object called "Patrol Points" or something like that?). If so, look at the Transform component on the parent object. The x, y, z values for your position should all be 0. If they have other numbers, they could be affecting the location that your monster is moving to. NOTE: once you reset the parent object to 0, 0, 0, you will probably need to adjust the patrol points. I hope that helps!
Did you reset the parent object? That is almost always the issue. If not, I'm not sure what seems to be causing the problem. So sorry we couldn't find it.

Is this code for a different enemy, using different patrol points? if so, I think the problem is that you will still want to call these patrol points 0 and 1. The array you make will also start by calling the first patrol point 0, no matter what. So each enemy you add will use the same code (you just need to put different patrols in the array in Unity). I hope that helps!
Hi, im running into a problem where the enemy keeps bouncing and flying around and teleporting but ive moved around the points everywhere and the enemy just doesnt stop bouncing high not like the bounce in the video this one flys all over
the ending step is having som problems. the scale of my monster is below 1 and thus in the decimals which doesnt work. But when i use 1, 1, 1. the sprite gets stretched after pressing play since the x scale is supposed to be lower
One tip I always suggest is not to ever change the scale (or animate) the parent object. If you do, you lose the ability to manipulate its scale and cane run into conflicts with your animator. As a rule, I do physics and flipping on the parent, and then any animation or scaling on the child. That might help. If you don’t want to change anything, you could just try using your own numbers. Instead of 1 and -1 for your x values, try setting the to the positive and negative values that your sprite is set to. Or you could try multiplying the x value by 1 and -1 instead of directly setting it. Hope that helps.
I have a few problems I encountered. First, the enemy changes in Z position when I press play. It also disappears, but the collider is still there. So how do I make the enemy stay in the same Z position in play when it was in the scene?
Have you checked the z position of your patrol points? It's possible the enemy is orienting to those (Also, if your patrol points have parents in the hierarchy, make sure they are also zeroed out).
@@NightRunStudio I have changed the Z position for all of the sprites, but even now the enemy is still in the same position as it was before if I press play.

first one is the enemy which is continuously jumping to the end of point 0, and the second is it is not coming to left side and staying at right end point by continuously hopping.

Usually that means that the enemy is not able to get close enough to the patrol point to trigger a turnaround. While playing, try switching to scene view and move the patrol point up or down a little. Chances are a little adjustment should get everything working.

@@migs_2559 Alright, well that was worth a try (it's usually the thing that gets people). Taking a look at your code, I think the issue may be some misplaced curly brackets. At the moment, once you switch your destination, you are missing a closed bracket. So now, it will only check if you have patrol destination #2 IF you have patrol destination set to 1 (which will never happen).
While you are adding the fix, it is often helpful to include some debug statements. For example, if you add some Debug.Log("reached destination 0"); at the point where you detect destination 0, you can find out which parts of your code are firing and which parts are failing to be exectued.

If you are flipping using localScale, you need to use the negative version of whatever you set your scale to. So if you have changed the scale of the object to something other than 1, -1 wont work for flipping. In that case, you could just multiple it by -1 (so it will just become the negative version of itself), or hardcode in the negative version of whatever your scale is set to. Hope that helps!
@@NightRunStudio Didnt expect youd reply but man Thank you for the info
i've got a few problems with this
the first on is that it only goes to one direction and can't go to the other.That only happens when i set the patrol destination to 2 but when i set it to one or zero it starts having a panic attack
The second one is from the other video about enemy chase.The code doesn't work
I'm happy to take a look at your code for the enemy chase.
As for the freak out, that usually means that the enemy is unable to properly reach one of your patrol points (often, it is set too high or too low and the enemy can actually get to it)

@@randomperson.0-0 So... I think your problems are stemming from the fact that you are comparing your Player transform to your player transform. What you want to check is the difference between your player's transform and the enemy's. Otherwise, the chase conditions will never be true.
@@NightRunStudio hmm alright thanks for the advice
tho another problem is that my enemy only goes to one destination
@@randomperson.0-0 No problem. As for the enemy only going to one destination, I can think of 2 reasons:
1) Make sure that your code is comparing the enemy's position to his desired position
2) Make sure that he can actually reach the destination (that it's not too high or too low). You can check this by firing a Debug.Log when his position is == to the desired position. If this fires, you'll know he is reaching it, if not, you know he can't reach it).
You are a life saver👍
Haha. Glad it helped. Good luck with your project!
I'm having problems. When my enemy reaches patrol point 0, it just stays there and doesn't turn start moving to patrol point 1. My code is exactly as it is in the video.
This is usually a problem with the way things are set up in Unity. My first suggestion would be to put a debug.log statement in your OnTrigger method (right at the top). That way you can make sure that your enemy is recognizing when it reaches the patrol point. If that’s working, one other common problem is that people often mix up the patrol points and put them on the wrong sides of the enemy (so when it reaches one, it knows to go to the next one, but can’t because it’s in the wrong direction). The debug.log is a good place to start though, as it should help you diagnose where the problem is.
Let me know if it is still giving you trouble after you try that. Cheers!
Hey, so it turns out I forgot to change one of the numbers in the code. It's now working fine. I really wish I had realized this sooner. 😅
@@BozKolodziejczyk Oh, I hate when that happens! So glad to hear you figured it out. Good luck with your project!
Hello and thank you for the video :) I have a weird problem that when I add the script made in this video to the character it stops the player damage from working.. Soon as I take it off though the player damage works as normal though!
That's pretty strange, since this one only deals with movement. I guess it depends on how your damage script works. Feel free to pop into my discord and share your code if you want. I'd be happy to take a look.
hey having a problem with the flipping part, when it flips it will teleport the sprite half way to the other patrol point.
That probably means your sprite’s pivot point isn’t centred (so it is flipping based on an axis that is off to one side). If you click on you sprite in the assets folder, the go to your sprite editor, you should see a little blue circle on the sprite. Make sure this circle is in the centre, as that is the point from which you will flip. I hope that helps!
@@NightRunStudio I got it working my z wasn't the same for the sprite and the parent object. it was fixed once I made them the same.
@@onedigits9755 That makes sense. Glad to hear you figured it out!
@@NightRunStudio Hi, mine has this exact problem but the pivot is centered and the z is the same on both the parent and sprite. Is there anything else that could possibly resolve this issue?
@@sillytoonss Is your x position the same on the child as on the parent? One thought is that your parent may be flipping, but if it is centered at a different x position than the child, the child would appear to teleport.
i have a problem where the enemy goes to the other side of the map, then starts doing the patrol, also for some reason he no longer has a collision, meaning he doesnt collide with anything anymore and goes out of bounds, any idea on the fix?
This is usually an issue to do with parenting. If the enemy, or the patrol point is a child, it will add its parent's position to its own... As a general rule, make sure that the parent of the enemy and of the patrol points has 0, 0, 0 as its position. Then the children should behave better. Hope that helps!
Nice vid again! 🔥🔥
Thanks!
Hi! I have a problem where my enemy only moves to the left, even when i assigned it to the patrol point on the right it still goes left. And also it only moves to one direction. I tried putting Debug.Log in the if(patrolDestination == 0) and the console shows nothing.
It definitely sounds like your enemy is failing to switch destinations (especially if your debug isn't printing to the console). This could be a number of problems. Does your enemy continuously move left, or does it move left and then get stuck once it gets close to your patrol point?
If it's the latter, then it is usually a case of the enemy getting close to the patrol point, but not actually being able to reach it. This can be fixed by moving the patrol point to a more accessible location (often it is set too high, or is in the ground so the enemy can't get there). You can test this while in play mode by going into scene mode and moving the patrol point at runtime.
If that doesn't work, feel free to paste your code and I can take a look. Good luck!
@@NightRunStudio This is the code, my enemy is also not able to go back and forth between those patrol points. What i understand is that the enemy does not even recognize the patrol points?

@@ahmadzufar1112 The code looks good. To solve this, I will need to know what your enemy is doing? Does he move left forever, or does he move for a while and then get stuck?
The fact that your debugs are not printing tells you that the enemy is never reaching the patrol points. What might be helpful is to add a debug right under the MoveTowards lines. Something like:
Debug.Log("Distance to patrol point = " + Vector2.Distance(transform.position, patrolPoints[0].position);
this code, should constantly tell you how far the enemy is from the patrol point (that way you can see if it is actually counting down and where he is close to the patrol point or not).

Which part is giving you trouble?
@@NightRunStudio I do not understand the part with transform.position and when you need to use methods like MoveTowards and and Distance. I guess it does take some time to learn... How long did take for you to learn C# ?
I had been coding for about 6 months when I started this channel, and about 3 years now. I still keep learning stuff all the time. The trick is to keep working at it(which it sounds like you are!).
MoveTowards and Distance are helper functions that Unity provides to keep us from having to type more code. As with most things in coding, there are often many ways to do any single task. I chose this one for the video as it requires less code, but there’s lots of way to go about it.
it still moves after its dead help
That's strange. The easiest way around this is to destroy the enemy when it runs out of health (Destroy(gameObject), but if you don't want to do that, you may need to turn off the patrol script. (Feel free to pop into the discord server if you want to get into details).

@@faizalaliapriyono1096 Okay! It's definitely a bracket problem. The coordinates for you Vector2.Distance should be in their own set of brackets, and the comparison (the < .2f) should be outside the brackets. Right now, the code isn't sure what to do with the less than sign. It should read:
if(Vector2.Distance(transform.position, patrolPoints[1].position) < 0.2f)
this way it can find the distance, THEN compare it to .2f.

@@NightRunStudio oh thanks mate, my bad for not realize that.. thank you so much for helping me. love your video👍👍
I love your tutorials but this one did not work. I dont know what ı am doing ı tried every thing but it does not work. So if you can reply to this commen ı wil share the info of the situation.
Feel free to give me some more details (or to pop into Discord for easier back and forth). That said, a common problem in this video is that the patrol point needs to be set at exactly the right height so the enemy can actually move to it (if it's too high, he will gyrate back and forth underneath it).
Additionally, some people parent the patrol points (to clean things up), but then miss the point that the new parent has it's own set of coordinates. Now, when they enemy tries to find the patrol point, he adds the parent's position and the patrol point's together). Anyways, thought those might help, but feel free to give more details if not.
I had the same issue
I am having a problem. The enemy moves but when it reaches a point it just keeps moving whitout stoping. I have tried changing them or adjusting the height but nothin works. Here is the code if it helps:

Nevermind actually I mare it so that the points move with the enemy so it would never reach them. After i realized the scale was weird but i maneged to fix it somehow and it works great. Thanks for the tutorial!
Glad you figured it out! Good luck with your project.
how would you make the enemy ai jump over obstacles though
Probably the easiest is with a collider set to trigger that you put in front of the enemy, then in the ontrigger method, if the collision object is tagged as ground you apply a new velocity to your rigidbody so the enemy jumps.
While using that system you have to create a points in hierarchy main fork for each enemy, so its VERY BAD idea to do it like that. What if you have just 10 enemies? For each you create 20 patrol points in main tree...
I hear you. I definitely wouldn’t suggest this for games where you have large levels. This is more aimed at beginners, who appreciate the visual approach to setting patrol points. But your point is taken. If you have much more than ten enemies in a scene things can get untenable.
@@NightRunStudio Thnx friend, so what about the idea to create a video with a really good system? I didnt found a good one for 2D, so this content could be really unique and it really helps a lot of peoples do less mistakes even at the start of their gamedev way.

What happens if u use it for 2 monsters
I would just create separate patrol points for each monster, and then you should be all good.
SO I have a very odd problem. My enemy weak point just falls off and lays on the floor once they start to move and I have no idea why. They still hurt me but I have to find the invisible weak point on the floor to kill them now. Any tips on how to fix it?
Did you put the rigidbody on the weakpoint? That would explain why it suddenly has physics.
@@NightRunStudio Oh it was! But now it just stays in place where the enemy spawned in. It doesn't follow at all.
Did you put the rigidbody back on the parent object (and remember to hook it up in your inspector?). If that’s not it, it might be time to try putting some debug.logs in your code to test which lines are running and which are not being executed.

Alright, so I'm pretty sure your problem comes down to a misplaced bracket. (Man, I hate those things sometimes! :)
In the video, you may notice that the if statements contained the patrolDestination checks are fully self-contained. In your code, the if(patrolDestination == 1) line is actually WITHIN the same logic that checks if (patrolDestination == 0).
To fix, you will need to have TWO closed brackets after the line that sets your new destination:
patrolDestination = 1;
}
}
That should help to keep the logic for each destination separate. Hopefully that solves your problem. If not, at least we fixed one problem, and you can let me know and I'll take another look.
Cheers!
i have a problem
the problem is that the weak point don't move with the monster
can you help me please?
and sorry for my bad english
Is the weak point on your parent object, along with the script? If so, they should be moving properly. I usually try to keep physics (rigidbody and colliders) on objects that are NOT the sprite-that way the sprite doesn’t get separated from the rest of the object.

Can I share my screen with you?
So you can help me?
when I hit the play button my enemy gets too much small it is a problem can fix it ? pls
That sounds like a problem with your scale on the enemy’s transform component. If you have changed the enemy’s scale to something other than 1, and then use scale.x to flip the enemy, it can mess up the sizing. For example, if your x scale for the enemy is 3.2 then when he flips it will need to be -3.2 I would start by checking those values.
@@NightRunStudio Pls check it
@@NightRunStudio Yes I change the scale of enemy X to 2.5 Y to 2.5 Z to 2.5
@@niveditaph8778 So, it will be important to make sure that when the enemy turns around (when he reaches the patrol point), you set his x value to -2.5 (not to -1). That would cause shrinking.
Sorry I forgot to add f in front of the number that is why I was having an error Thanks for your help :)
My enemy is bouncing up and down instead of turning around even tho i raised the patrolPoints
If he bounces up and down, that almost always means he can't reach the destination point. Adjusting the point should help. That said, you could also add a Debug.Log("hit destination point"); that goes off when he hits the patrol point (that way you can know for sure if the enemy is actually reaching it.

Hmmn… sounds like a problem with the setup in Unity. The enemy should always move toward a patrol point (hence the MoveTowards function). If it is moving past the point and keeps going then it sounds like it is targeting the wrong thing (as it will always move toward its target).
Other than checking the Unity setup, I would also put in some debug.logs. For example I would put some under the if(Vector2,Distance statement… I suspect it is not firing, but if it does it would at least eliminate the idea that the enemy is moving to the wrong target.

@@toustik5161 Your code looks good--so it will definitely be a problem in Unity. I suspect that the issue probably has to do with a parent object.
In your hierarchy, do you have a parent object that your patrol points are children of? (Probably an empty object called "Patrol Points" or something like that?). If so, look at the Transform component on the parent object. The x, y, z values for your position should all be 0. If they have other numbers, they could be affecting the location that your monster is moving to.
NOTE: once you reset the parent object to 0, 0, 0, you will probably need to adjust the patrol points.

Is this code for a different enemy, using different patrol points? if so, I think the problem is that you will still want to call these patrol points 0 and 1.
The array you make will also start by calling the first patrol point 0, no matter what. So each enemy you add will use the same code (you just need to put different patrols in the array in Unity).
I hope that helps!

Hi, im running into a problem where the enemy keeps bouncing and flying around and teleporting but ive moved around the points everywhere and the enemy just doesnt stop bouncing high not like the bounce in the video this one flys all over
the ending step is having som problems. the scale of my monster is below 1 and thus in the decimals which doesnt work. But when i use 1, 1, 1. the sprite gets stretched after pressing play since the x scale is supposed to be lower
One tip I always suggest is not to ever change the scale (or animate) the parent object. If you do, you lose the ability to manipulate its scale and cane run into conflicts with your animator. As a rule, I do physics and flipping on the parent, and then any animation or scaling on the child. That might help.
If you don’t want to change anything, you could just try using your own numbers. Instead of 1 and -1 for your x values, try setting the to the positive and negative values that your sprite is set to. Or you could try multiplying the x value by 1 and -1 instead of directly setting it. Hope that helps.
I have a few problems I encountered.
First, the enemy changes in Z position when I press play. It also disappears, but the collider is still there. So how do I make the enemy stay in the same Z position in play when it was in the scene?
