If it seems like even after you edit the CharacterController2D script your FirePoint doesn't flip on the y-axis, click on your Local/Global button at the top of the editor. The FirePoint is flipping, but if you have one of those on and not the other, it will appear as if it's not. Regardless, as long as you've inserted the code as instructed, the bullet will come out of the FirePoint in the correct direction no matter if you have Local or Global selected.
It might be a little late to mention, but if your effect can't dissapear after it finished playing, try these steps: 1. Go to the animation tab of your effect and add an event on frame n+1(3rd block on the right of 'Samples') 2. Create a destroy script and add it under your effect prefab 3. Go to the inspector of the animation event you just added, type 'Destroy' into the function column, no brackets And that shall do the work. My script looks like below: public class DestroyGameObject : MonoBehaviour { public void Destroy() { Destroy(gameObject); } } I got this solution from chat-GPT and it worked like magic. Hope it helps :)
Not gonna lie but he is better at speaking then my teachers, he inspires people to do stuff, he makes people positive by his smile dude, i just love watching him
No man, thank you! Thank you for connecting with your viewers even tough you have 570,000 subscribers. It really shows that you're one of those rare youtubers who actually interact with their viewers which makes me feel happy and exited every time I watch your videos!
To be honest, he's definitely the person I'm gonna go to whenever I get started with unity. The videos seem so helpful A different kind of helpful, like I'd actually learn from them
For those who cant get the Firing Point to flip with the sprite, copy lines 114-124 which can be seen seen at 2:47, this ties in with the lines at the bottom.
Interesting, I could not figure this out and somehow managed to get the bullets to switch direction when the player turns but the firepoint is still fixed. So basically it's still broken, I will look into your suggestion. Thank you!!
Your tutorials are so easy to follow, and really fun. They are really positive, and user friendly too. You have helped me so much, as a beginner game dev. Thanks Asbjorn! :)
If u want that the bullet disappears after leaving the camera screen use: public class Bullet : MonoBehaviour { public float speed = 20f; public int damage = 20; public Rigidbody2D rb; public GameObject impactEffect; // Start is called before the first frame update void Start() { rb.velocity = transform.right * speed; } private void OnTriggerEnter2D(Collider2D hitInfo) { Enemy enemy = hitInfo.GetComponent(); if (enemy != null) { enemy.TakeDamage(damage); } Destroy(gameObject); } void OnBecameInvisible() { enabled = false; Destroy(gameObject); } } It's important for the level design i think.
If anyone had an issue with the animation not disappearing after it's end, the solution is to add a script to the gameobject that is animated by it (in that case, impactEffect and destroyEffect) that has a function that destroys the gameobject. Than all you've gotta do is to add an extra frame to the animation and place an animation event that will trigger the destroy function
@@shwk77 Hey, don't know if you were able to fix it or not, but here is what I did. Since we are instantiating a impact/hit effect prefab rather than changing the animation state, you need to attach a script to the hit/impact effect prefab and create a public function which the destroys the gameObject, this function would be called after the final frame of impact effects using the animation event.
@@SDSFDSF631 What I did (a pretty dumb way) is created a script in the destroyEffect prefab in the Start frame like "Destroy(GameObject, 0.5f)" which makes it looks like that destroyEffect dissapeared right after it finished animation, but you can change the time to whatever you feel is right.
I'm seven minutes in and you're already providing a lot of clarity to my shooting script. Other tutorials works but their rather overly complicated and don't explain much- you fix both issues. Very good job :D
You SAVED me life. I've been trying for 2 hours to figure how to get the bullet to shoot across. (Using other tutorials) This one nailed it step by step. Thanks!!!!
Alright if anyone is wondering how they can get their character to shoot while crouching here's how: 1. Make another firepoint for the crouching position 2. go into the weapon script and change it to this: using System.Collections; using System.Collections.Generic; using UnityEngine; public class Weapon : MonoBehaviour { public Transform firePoint; public GameObject bulletPrefab; public Transform firePointcrouch; // Update is called once per frame private void Update() { if ((Input.GetButton("Crouch") == true && Input.GetButtonDown("Fire1"))) { CrouchShot(); } else if (Input.GetButtonDown("Fire1")) { Shoot(); } void CrouchShot() { Instantiate(bulletPrefab, firePointcrouch.position, firePointcrouch.rotation); } void Shoot() { Instantiate(bulletPrefab, firePoint.position, firePoint.rotation); } } } 3. back into unity, place the crouching firepoint into the new firepoint slot on the weapon component That should make it so you can crouch and shoot.
While you wait, there are some cool tutorials about this subject already! :) Here's one: th-cam.com/video/EOSjfRuh7x4/w-d-xo.html. This stuff also really helped me a lot: juhakeranen.com/dev-mistakes-pdf/
For people using the Prefab approach, please do remember to utilize object pooling in order to maximize performance. I believe Brackeys has a video set up for this.
If you have a problem with the animation not disappearing after it's over, the solution is to add a script to the Object "DeathEffect" that has a function that destroys the gameobject after a bit of time (the time the animation takes). This Code worked for me : using System.Collections; using System.Collections.Generic; using UnityEngine; public class DeathEffect : MonoBehaviour {
I just love your tutorials. Even If I don't really need that at this moment it's so useful and helpful for further struggles. Always find what I was looking for and even more. And you do always smile and make it all interesting. Just great job, thank you :D.
I know this is an old video so I don't know if you'll see this but this helped me so much. I was at a dead end with my game and it was really disheartening. I felt like I couldn't progress if I hadn't got this part sorted and even though it's not exactly the type of shooting I wanted, I was lucky to find this and I'm glad I switched it out to shooting just along the X axis. Thank you!!
For anyone trying to get their bullet to shoot forward instead of right, use forward in place of right, or if that doesnt work, use up. You 2D game might be oriented so that forward to your camera view is actually the green axis, or up.
Using colliders on the bulletsbis quite inefficient. It is much better to do a linecast from the bullet's last position to it's current one. This also means you can make bullets that can go through walls and find the out point.
On your bullet script, you have a variable that keeps track of the last position it was in. Every frame you do a linecast from the last position, to the current position. If the bullet collided with something during that last frame of movement, the linecast will pass through what the bullet hit. This solves the collision system not resolving a hit, because no matter how far the bullet travels in that one frame, the linecast will still pass through whatever the bullet hit. Regarding the wall part, if you want penetration, when you do the linecast, you can check if the linecast passed through a wall. If it did, you can use vector math to figure out where the bullet came out of the wall and at what angle.
@cooldude 4172 I don't have any experience with that engine, but a quick google search brought up the collision_line method which may help you docs.yoyogames.com/source/dadiospice/002_reference/movement%20and%20collisions/collisions/collision_line.html
Amazing, all your tutorials are dope, easy to understand and simply the best unity tutorials. Please provide us with more awesome tutorials like these. Looking forward. Much love😊
If anyone has a problem when shoot to right or left and bullet doesn't appear try to modify the position Z = 0 on the FirePoint, it's because bullet spawns out of the camera. PD: Hope this solve your problem :)
I had the same problem, i downloaded an empty png then add it to end of the impact animation and enemy death animation it fixed mine but im sure there is much better solution
Can you make a video on how to do 360 degree aiming on a 2D platform game like the one shown here? Making the character's arm and head rotate depending on where your mouse cursor is positioning.
Tip to prevent lag (if you have large open areas or if it some how gets through a barrier) You can make a script that delays the bullet after a while such as Void start () { Invoke(“despawn”, 20); } Public void despawn () { Destroy(Gameobject); }
Could you go over the controller script in an upcoming video? It would be really helpful to understand what's happening in it step-by-step so when we start our own projects we don't have to rely on other people's scripts
If ur enemy doesn't disappear if it's health goes under 0 health just delete the line "Instantiate(deathEffect, transform.position, Quaternion.identity);" in the enemy script.
Thank you so much, I just started with Unity and wasn't sure how to create objects that kept the same components. Because of this video I learnt what a Prefab was, which solved my issue.
19:50 if you want to wait for exactly 1 frame, then imo it's more accurate to use yield return Time.deltaTime because that's the length of the last frame. of course it's not 100% accurate because of varying frame lengths but it should be closer than 0.02 seconds
BEST shooting tutorial for 2D out there, thank you! I got a question tho and I really hope you'll answer, how did you turn the impact animation into a useable prefab? I'm banging my head over this and it should'nt be so hard haha
Brackeys. I know this request might be pointless, but could you please, I beg you, make tutorial with shader graph related to rain ripples and rainy window drops and if you find time, character that looks like a ghost, but shaped like character :)
Glad to see both of the methods covered! :D I'm personally a RayCast-guy, because Vector performance lol but I use ; Ray ray = new Ray(transform.position , transform.left); RaycastHit Block ; if(Physics.Raycast(ray , out Block , 6f)) { Enemy enemy= Block.transform.GetComponent(); if(enemy != null) { enemy.TakeDamage(10); } }
Hi, If someone could help me, I am doing the prefab method but whenever I shoot the bullet just stops in front of the enemy and doesn't destroy or print Enemy(or "Frog" in my case) in the console.
Quick tip: Add a float: impactEffectTime This is the time the impact effect animation plays, roughly. The effect should end on an invisible frame, so it doesn't show, but if you look at the inspector, the prefab is still there. After a few thousand shots, this could slow down your game. With a timer of, say, half to one second, you could destroy the effect prefab as well. By having this as a variable, you can use much longer effects, in case you have special weapons with much longer effects in the future. Like a rocket with secondary explosions. This will then clean up the effect prefabs for you and you shouldn't have more than maybe 10 effect prefabs at any given time, and no significant impact on performance. To implement, just copy the Destroy command from the bullet itself, place right before the bullet, change the variable name from the bullet game object to the effect game object and add the timer as a second parameter. It looks like it would destroy the effect prefab first, but the second parameter is actually a timer, so the bullet would be destroyed instantly, and the effect would be destroyed impactEffectTime seconds later.
I have a really big problem! After I create OnTriggerEnter2D, when I play the game my bullet just shows up in front of me for a split second then disappears. I would imagine this happens because the bullet doesn't know what is an enemy or not. Can someone please tell me how I can fix this problem?
Thanks bro. Just one request from me - you can leave it if you don't find it worth teaching. Can you make video on a game where we hit the api to send data to server and then again hit the get api to receive the data back from server... It could be a series of tutorials where first we login through social media and save our email and pswd to server and then save the details of user like coins,win%,powerups,loose% etc. What do you think ?
Hi! Can someone help me? I've been trying to add an animation when my character is shooting but I can't find a way to make it work... Either the character stays stuck at the end of the animation or the animation straight up doesn't play ;^; I've tried animation events and pretty much everything else...
for the "the character stays stuck at the end of the animation " problem, destroy the character animation when it's done and instantiate the origional object
Try using this public class Gun : MonoBehaviour { public Transform firePoint; public GameObject bulletPrefab; public float Cooldown1 = 0f; // Update is called once per frame void Update() { Cooldown1 -= Time.deltaTime; if (Input.GetButtonDown("Fire1")) { if (Cooldown1
im a big fan of your videos. i've seen all your videos so far! and learned almost EVERYTHING of unity with you. Can you make a tutorial for a turn based combat like final fantasy or any rpg turn based?
In your animations, attach a collider trigger and animate it to follow the weapon, then apply damage with that collider similar to how the bullet detects impacting an enemy
that's a good start but how should i go about balancing the weight of my enemies and forces of each attack to allow for things like juggle combos, launchers, wall bounce, these kinds of things?
@@guigondi7671 well you could make it that when you perform a launching attack it moves the enemy up a certain distance, and that when you when you attack an enemy they enter a stagger animation that keeps them from attacking. Each hit could move the enemy up a certain distance to keep them in the air, or each hit could freeze them in place for a split second so you can continue your combo. Then make the last hit of your combo a finisher that launches the enemy far away so that you can't do zero to death combos. Understanding basic physics equations like the kinematic equations, and work will help you precisely control the physics of the combo system to make it feel the way you want.
How do you clean up those lingering "Impact Effect" game objects? You can see them build up at: th-cam.com/video/wkKsl1Mfp5M/w-d-xo.html The way I handled this: 1) Added a new script to the "ImpactEffect" game object called "AnimationComplete" 2) Created that script with these contents: public class AnimationComplete : MonoBehaviour { public void OnAnimationComplete() { Destroy(this.gameObject); } } 3) Added an event to the end of the ImpactEffect animation whicah calls the "OnAnimationComplete()" event.
I have run into a problem, for both the enemy and the projectile the last frame of the deathEffect/impactEffect lingers on screen permanently. Can some one help please?
To people who have trouble with gunpoint flipping issue(Gun point changing direction) you can use this Have 2 Variables private bool isFacingRight = true; private bool isFacingLeft = false; Then the rest of the logic is below Also this is a script if you designed your player facing right if (movementX > 0) { anim.SetBool(WALK_ANIMATION, true); anim.SetBool(JUMP_ANIMATION, false); if (isFacingRight == true) { transform.Rotate(0f, 0f, 0f); isFacingRight = true; isFacingLeft = false; } else { transform.Rotate(0f, 180f, 0f); isFacingRight = true; isFacingLeft = false; } } else if (movementX < 0)//we are going to the left { anim.SetBool(WALK_ANIMATION, true); anim.SetBool(JUMP_ANIMATION, false); if (isFacingLeft == true) { transform.Rotate(0f, 0f, 0f); isFacingLeft = true; isFacingRight = false; } else { transform.Rotate(0f, 180f, 0f); isFacingLeft = true; isFacingRight = false; } } Note: The anim.SetBool stuff are my animation code you can ignore that but the logic should work Hope it helps anyone :D
3 ways to do it... Using ray-cast but spawning a prefab to follow from birth to end of ray cast! Making it more realistic and good! And you can easily adjust speed of following or reduce or what ever lol! Its very effective, stable and great way to make a battlefield 4 like shooter! (Realistic) the key between the two lol
Danian D. No problemo! But i havent tested it yet, i see no reason this wiuldnt work, infact the first point he said which was the one i used in my 2d game and believe me... that was messy lol...specially with my inability to understand a good approach to coding! But his method i believe is closer to the perfection that is real life physics!
Lol, that’s just the same as using a prefab. The only difference is the mode of travel for the prefab. Real life physics also have bullet drop, so that method alone wouldn’t make anything more realistic.
I think he meant more stable because the hit calculation doesn't rely on an actual prefab flying towards the target. Knowing some of the weird glitches with physics in game engines, raycast seems like the safer alternative. Also let's you do whatever you want with the now-only visual bullet prefab.
@@iwant2tryhard337 Yeah you could just make a sprite with that explode animation, make it play wants it enters the scene (and if you want to make it so that it deletes itself once it's done to save on space) and then juts turn it into a prefab.
I dragged rigidbody in the bullet script but it gives me the "circle with line in it" or "no" sign I fixed it in another project but I cant seem to remember what I did!
Great tutorial, but one personal problem I'm having is that my bullets like to be invisible. Now I understand their new to the world, but I kind of don't like it when their invisible...
Sir, this, like all of your other tutorials are INCREDIBLE and AWESOME! Thank you for sharing your genius with the rest of us. I think it would be awesome to see a tutorial on how to create a map for 2D games like we see in Metroidvania games like Metroid, Symphony of the Night, Shadow Complex, etc. (tutorials on this subject on the internet are lacking as a whole). Thanks! :)
For me the effect is "BulletExplotionEF", I solved with: Destroy(GameObject.Find("BulletExplotionEF(Clone)"), 0.2f); Inside of the Ontrigger event, but to destroy the cloned bullet when this doesn't hit anything I'm still not getting, I tried to put in the update method without success :(
federico del nero I solved creating a function to destroy unused objects, you can create a public variable to your object which tell you is has to be destroyed

Haha the look on your face when the handgun showed up. Amazing. 😂
Haha
Can you make a video on how to do 360 degree aiming on a 2D platform game like the one shown here? Making the character's arm and head rotate depending on where your mouse cursor is positioning.
Tip to prevent lag (if you have large open areas or if it some how gets through a barrier)
You can make a script that delays the bullet after a while such as
Void start ()
{
Invoke(“despawn”, 20);
}
Public void despawn ()
{
Destroy(Gameobject);
}
Could you go over the controller script in an upcoming video? It would be really helpful to understand what's happening in it step-by-step so when we start our own projects we don't have to rely on other people's scripts
Dude the way you approach your videos is so positive. You emit good vibes
If ur enemy doesn't disappear if it's health goes under 0 health just delete the line "Instantiate(deathEffect, transform.position, Quaternion.identity);" in the enemy script.
Thank you man, saved my day!
Thank you so much, I just started with Unity and wasn't sure how to create objects that kept the same components. Because of this video I learnt what a Prefab was, which solved my issue.
Can you do a tutorial on making particle clouds pls. I need help for making one in my game. I don’t want to use a skybox by the way.
19:50 if you want to wait for exactly 1 frame, then imo it's more accurate to use
yield return Time.deltaTime
because that's the length of the last frame. of course it's not 100% accurate because of varying frame lengths but it should be closer than 0.02 seconds
Brackeys, your video is make me to learn about Unity. Please make 2D Melee Attack in Unity. Thank you.
Im so glad I found this video :D super easy to understand, and exactly what I was looking for. Thank you!
12:11 "Super coal" XD
Brackeys is back at it again with the amazing 2d tutorials
I just made a AR app in unity, I feel so accomplished in life!
Cool!!!!
Name of the app so we can spam 5 stars? :D
@@MaThMaTa1000 hey thanks man, but it's just a fun little project I made, it isnt on the app store.

BEST shooting tutorial for 2D out there, thank you!
I got a question tho and I really hope you'll answer, how did you turn the impact animation into a useable prefab? I'm banging my head over this and it should'nt be so hard haha
Who else is just trying to be like Dani
Same...
But kinda THICK
X Gamer X Really THICCCCC
Me
But is it just me or is the gun locking kinda THICK
Is it me or is this comment lookin kinda THICK?
Dude I absolutely love your videos, and this helped a lot. I would not be using unity if it was not for you! Keep making AWESOME content!!!!
Man, I can’t sleep without hearing your voice lol, so soothing and professional
Man love your tutorials ever since I'm learning from ya I want to add a Easter egg of you in one of my games because you deserve one!!
Brackeys. I know this request might be pointless, but could you please, I beg you, make tutorial with shader graph related to rain ripples and rainy window drops and if you find time, character that looks like a ghost, but shaped like character :)
You could make a ghost by making a character transparent, ramping up its emission + using an bloom aftereffect to blur the edges
I want the ghost that looks like in call of duty black ops 4

"Hey Rigidbody, please move right according to our speed"
😂He's soo polite
Really an amazing tutorial! Love from Pakistan
Glad to see both of the methods covered! :D I'm personally a RayCast-guy, because Vector performance lol
but I use ;
Ray ray = new Ray(transform.position , transform.left);
RaycastHit Block ;
if(Physics.Raycast(ray , out Block , 6f))
{
Enemy enemy= Block.transform.GetComponent();
if(enemy != null)
{
enemy.TakeDamage(10);
}
}
Hi, If someone could help me, I am doing the prefab method but whenever I shoot the bullet just stops in front of the enemy and doesn't destroy or print Enemy(or "Frog" in my case) in the console.
I DON'T HAVE A SOLUTION BUT IM BOOSTING THE COMMENT SO MORE PEOPLE CAN SEE IT AND MAYBE ONE OF THEM CAN HELP YOU
do you have isTrigger enabled under your bullet's box collider ?
Same and if I turn on isTrigger it just phases through
Nevermind: Solution: I wrote OntriggerEnter2D instead of OnTriggerEnter2D
This video has so much value, keep up the good content!!
" And I will see you in the next video! "
Okay let's just scroll down and see the next on-
" *SCREAMS INTO MIC* : *AHGHGHGAHFHAGHGAHGA* "
this video came out just when i needed it, thanks
10:54 “Well then we want to die”
Excuse me?
Quick tip:
Add a float: impactEffectTime
This is the time the impact effect animation plays, roughly. The effect should end on an invisible frame, so it doesn't show, but if you look at the inspector, the prefab is still there. After a few thousand shots, this could slow down your game. With a timer of, say, half to one second, you could destroy the effect prefab as well. By having this as a variable, you can use much longer effects, in case you have special weapons with much longer effects in the future. Like a rocket with secondary explosions.
This will then clean up the effect prefabs for you and you shouldn't have more than maybe 10 effect prefabs at any given time, and no significant impact on performance.
To implement, just copy the Destroy command from the bullet itself, place right before the bullet, change the variable name from the bullet game object to the effect game object and add the timer as a second parameter. It looks like it would destroy the effect prefab first, but the second parameter is actually a timer, so the bullet would be destroyed instantly, and the effect would be destroyed impactEffectTime seconds later.
I have a really big problem! After I create OnTriggerEnter2D, when I play the game my bullet just shows up in front of me for a split second then disappears. I would imagine this happens because the bullet doesn't know what is an enemy or not. Can someone please tell me how I can fix this problem?
Same problem here! Someone help usssss
Omg I'm having this exact issue and it's making me crazy. I can get it to injure the enemy but that's it.
disable gravity of the bullet from rigidbody and mark body type as kinematic
Same problem
same
Awesome video's! Newbie to Unity really appreciate your thorough explanations.
Thanks bro. Just one request from me - you can leave it if you don't find it worth teaching.
Can you make video on a game where we hit the api to send data to server and then again hit the get api to receive the data back from server... It could be a series of tutorials where first we login through social media and save our email and pswd to server and then save the details of user like coins,win%,powerups,loose% etc.
What do you think ?
Thumbs Up.
This is the happiest man on youtube (Machalla)
Don't forget to destroy the impacts effects after a few seconds because of performance issues
How do you do that?
@@thewiitard5515 Destroy (gameObject, lifetime);
@@DayMoniakkEdits It says that lifetime is an error
The Wiitard lol don't write "lifetime", put the amount of time in seconds, for example "3f" to destroy the bullet after 3 secs :)
@@DayMoniakkEdits my problem is that the animation doesn't delete when its done it just stays at the last frame of animation
thanks, I have been struggling to make my player fire but this tutorial helped me a lot
Hi! Can someone help me? I've been trying to add an animation when my character is shooting but I can't find a way to make it work... Either the character stays stuck at the end of the animation or the animation straight up doesn't play ;^; I've tried animation events and pretty much everything else...
for the "the character stays stuck at the end of the animation " problem, destroy the character animation when it's done and instantiate the origional object
Too bad I just found out about this pretty epic channel now. But I'm very glad that he made it, thanks for the epic tutorials
How do you make it wait time before next fire???(very important)
Try using this
public class Gun : MonoBehaviour
{
public Transform firePoint;
public GameObject bulletPrefab;
public float Cooldown1 = 0f;
// Update is called once per frame
void Update()
{
Cooldown1 -= Time.deltaTime;
if (Input.GetButtonDown("Fire1"))
{
if (Cooldown1
thanks again. this stuffs already hard to learn. without your channel id really be lost whenever I get in front of the computer.
7:19 just my bookmark
im a big fan of your videos. i've seen all your videos so far! and learned almost EVERYTHING of unity with you.
Can you make a tutorial for a turn based combat like final fantasy or any rpg turn based?
@Brackeys
Please, do a 2D tutorial on how to make melee atacks and combos.
I'd really like to try to make a 2D Devil May Cry
Gui G Dias yeah thats a good idea
In your animations, attach a collider trigger and animate it to follow the weapon, then apply damage with that collider similar to how the bullet detects impacting an enemy
that's a good start but how should i go about balancing the weight of my enemies and forces of each attack to allow for things like juggle combos, launchers, wall bounce, these kinds of things?
Hey I saw your comment on making a 2d devil may cry i'm interested in helping if you want some help?
@@guigondi7671 well you could make it that when you perform a launching attack it moves the enemy up a certain distance, and that when you when you attack an enemy they enter a stagger animation that keeps them from attacking. Each hit could move the enemy up a certain distance to keep them in the air, or each hit could freeze them in place for a split second so you can continue your combo. Then make the last hit of your combo a finisher that launches the enemy far away so that you can't do zero to death combos. Understanding basic physics equations like the kinematic equations, and work will help you precisely control the physics of the combo system to make it feel the way you want.
Im such a noob at unity yet you made this very clear! Good job you get a sub
How do you clean up those lingering "Impact Effect" game objects? You can see them build up at: th-cam.com/video/wkKsl1Mfp5M/w-d-xo.html
The way I handled this:
1) Added a new script to the "ImpactEffect" game object called "AnimationComplete"
2) Created that script with these contents:
public class AnimationComplete : MonoBehaviour {
public void OnAnimationComplete() {
Destroy(this.gameObject);
}
}
3) Added an event to the end of the ImpactEffect animation whicah calls the "OnAnimationComplete()" event.
All you have to do is to do Destroy(this.gameObject, 2f) the 2, or any var acts like a delay for destroying
Thanks
Thank you for this. You have been a great help for all of my projects.
i ran into an issue where my bullet wasnt moving at all, i had to re-assign the rigidbody in the inspector, in case this helps anyone
I ran into the same bug, but it didn't work. What do you mean by re-assign
Zachary Lamar so if you click on it in the inspector, then drag it into the slot where it is on the script
Thank you you are my favourite youtuber i watch you every day
0:49 the second guy has aimbot !
lmao
maybe brackeys is into hacking :O
I have run into a problem, for both the enemy and the projectile the last frame of the deathEffect/impactEffect lingers on screen permanently. Can some one help please?
same here!, did you find a solution?
@@bomber_g in the video the effect never "dies" he just added an extra animation frame where it goes invisible, but they are still there.
@ozmega do you know how to add empty keyframes? I can't seem to make it happen
Great tutorial as usual brackeys!
P.S. I think you meant "prefab shooting" @14:43
"Well then we want to DIE"
To people who have trouble with gunpoint flipping issue(Gun point changing direction) you can use this
Have 2 Variables
private bool isFacingRight = true;
private bool isFacingLeft = false;
Then the rest of the logic is below
Also this is a script if you designed your player facing right
if (movementX > 0)
{
anim.SetBool(WALK_ANIMATION, true);
anim.SetBool(JUMP_ANIMATION, false);
if (isFacingRight == true)
{
transform.Rotate(0f, 0f, 0f);
isFacingRight = true;
isFacingLeft = false;
}
else
{
transform.Rotate(0f, 180f, 0f);
isFacingRight = true;
isFacingLeft = false;
}
}
else if (movementX < 0)//we are going to the left
{
anim.SetBool(WALK_ANIMATION, true);
anim.SetBool(JUMP_ANIMATION, false);
if (isFacingLeft == true)
{
transform.Rotate(0f, 0f, 0f);
isFacingLeft = true;
isFacingRight = false;
}
else
{
transform.Rotate(0f, 180f, 0f);
isFacingLeft = true;
isFacingRight = false;
}
}
Note: The anim.SetBool stuff are my animation code you can ignore that but the logic should work
Hope it helps anyone :D
3 ways to do it...
Using ray-cast but spawning a prefab to follow from birth to end of ray cast!
Making it more realistic and good!
And you can easily adjust speed of following or reduce or what ever lol!
Its very effective, stable and great way to make a battlefield 4 like shooter! (Realistic) the key between the two lol
I was really hoping he would show this method, thank you for confirming it's existence!
Danian D. No problemo!
But i havent tested it yet, i see no reason this wiuldnt work, infact the first point he said which was the one i used in my 2d game and believe me... that was messy lol...specially with my inability to understand a good approach to coding!
But his method i believe is closer to the perfection that is real life physics!
Lol, that’s just the same as using a prefab.
The only difference is the mode of travel for the prefab.
Real life physics also have bullet drop, so that method alone wouldn’t make anything more realistic.
I think he meant more stable because the hit calculation doesn't rely on an actual prefab flying towards the target. Knowing some of the weird glitches with physics in game engines, raycast seems like the safer alternative. Also let's you do whatever you want with the now-only visual bullet prefab.
Danian D. Yes, also you can tell your ray-cast to fall towards gravity over distance with some coding ways...
Making it stable AND realistic.
Always great videos man, only wish other TH-cam videos had this level of polish :)
can you do me a favor? can you tell me more about deathEffect? what the heck is that? how to make it?
It is probably a particle effect he has in his assets folder.
@@lorcangarvin8723 Or an animation?
@@iwant2tryhard337 Yeah you could just make a sprite with that explode animation, make it play wants it enters the scene (and if you want to make it so that it deletes itself once it's done to save on space) and then juts turn it into a prefab.
@@lorcangarvin8723 how do you make it delete itself
you should use yield return null, yield return 0 performs a boxing of the unused 0 value
+1
Why is TH-cam showing me this exactly after he left ?
I dragged rigidbody in the bullet script but it gives me the "circle with line in it" or "no" sign
I fixed it in another project but I cant seem to remember what I did!
Great tutorial, but one personal problem I'm having is that my bullets like to be invisible. Now I understand their new to the world, but I kind of don't like it when their invisible...
Check the bullet prefabs Sorting Layer / Order in layer, it's probably layered behind stuff.
It's either too low on the sorting layers or your FirePoint is too close to your Player
You guys are helping me an amazing game 😄 can’t thank you guys enough for this
*Can you make a video about C# tutorial please?*
th-cam.com/video/pSiIHe2uZ2w/w-d-xo.html
Sir, this, like all of your other tutorials are INCREDIBLE and AWESOME! Thank you for sharing your genius with the rest of us. I think it would be awesome to see a tutorial on how to create a map for 2D games like we see in Metroidvania games like Metroid, Symphony of the Night, Shadow Complex, etc. (tutorials on this subject on the internet are lacking as a whole). Thanks! :)
i can't not destroy the impactEffect, pls help!
For me the effect is "BulletExplotionEF", I solved with:
Destroy(GameObject.Find("BulletExplotionEF(Clone)"), 0.2f);
Inside of the Ontrigger event, but to destroy the cloned bullet when this doesn't hit anything I'm still not getting, I tried to put in the update method without success :(
I have the same problem, the animation ends but the last frame remains on the scene. Can anyone help please?
federico del nero I solved creating a function to destroy unused objects, you can create a public variable to your object which tell you is has to be destroyed
add this script to the impacteffect with changing the time (that 0.5f ) :
void Start()
{
StartCoroutine(change());
}
public IEnumerator change()
{
// wait for 3 seconds
yield return new WaitForSeconds(0.5f);
Destroy(gameObject);
}a
This was really helpful
I really hope to see "shooting as particle system" guide in some future, cause alot of prefabs hit ur frame rate pretty hard
