I started to code games in unity and had an idea to make all famous video games chronologically. And your channel just fits me perfectly. I just want to thank your great work, keep doing this awsome content!
Once I get more familiar with Unity, I’m totally coming back to these videos. Given the fact that this video is two hours longer than the prior one, I’m almost afraid to suggest your next tutorial, but my vote goes to either Berzerk or Robotron 2084.
If you're like me, you immediately begin debugging if something doesn't match. If Pacman does not collide with the walls like he does in the video, just wait a few more seconds and let him explain the next few steps before you panic and debug for an hour... been a great tutorial though!
Be sure about 1:26:00 if your input isn't working correctly, I had to make sure my methods in the movement script were referencing the correct "direction" variable. If that makes any sense.
Very nice Tutorial, i made this game from my own, but couldnt figure out how to handle the Movement of the ghosts. Your tip with Nodes as TileMap Tiles was very nice and easy to understand. Thank you so much!!
The tutorial has been great so far. I had to change the position of the Connection_left/Right gameObjects in order to make the passage work (from -13.5 to -13 / from 13.5 to 13). If I don't do it, Pacman gets stuck in a loop moving from one passage to another. I guess the rigidbody physics are more sensitive in Unity2022.3.8f1? Did anyone else have this problem while making the passage?
I have the same problem here! But already solved it. I move the Passage object just a little bit farther with the Connection so that will be work. For example, the video said the position of X Axis Passage_Left is -14.5, so I just move it into -15.5
@21:30 etc - re: accidental pellets "under walls" - you can always uncheckbox in inspector to turn off each tile map, say the walls one - to see just the "pellets" and then vice - versa - a nice easy check to see if there's strays, overlaps etc - and then checkbox on like default cheers thanks nice tutorial overall

I have run into the same issue, except maybe a little different? None of my ghosts won't leave home, and I get this error message "Coroutine couldn't be started because the the game object 'Ghost_Clyde' is inactive! UnityEngine.MonoBehaviour:StartCoroutine (System.Collections.IEnumerator) GhostHome:OnDisable () (at Assets/Scripts/GhostHome.cs:12)" Have you found a solution?
Great video, helped me a lot, but I think that the chase behaviour could be improve using dijkstra to find the path or else it would bug when the ghost and pacman stay between 2 nodes but on different y, this should cause the ghost to go back and forth if pacman does not go out of that area, but for an educational video, very great work!!
Hi were you able to implement dijkstra in your chase behaviour? If so, could I please see your code as I have been trying to implement it but am struggling
@@hani8261 I have been very busy since then so I weren't able to implement it, but I can tell you my idea. I simply treat each turn and crossroads as a node and pacman as a node also, then you can perform djkstra to find the optimal direction for the ghost to move , I reccomend performing the algorithm or updating the direction each second to optimize the game. I hope this help you, and if you can please tell me if you got it.
I really like your work. However i think youtube want people end your video to get monetized...so i suggest to split your videos in more affordable sections...ihmo i'd like to see dig dug (or Pooyan if i can dream) :D
This is one of those games where you could spend $1000 in quarters and still not get very good at it. The worst most difficult, though, was Asteroids. Trying to control the flight and rotating to shoot only with buttons and no joystick. Maddening.
You should try the old arcade Rip-Off game. Same type of flight control and shooting (but of enemies trying to steal a collection of cargo you're defending), but with increasingly difficult enemy ships and with the addition of a cooperative 2nd player who you could also accidentally shoot. lol
Great tutorial! Just checked the FAQs and comments but it doesn't look like this others have had this problem before. I am having an issue where PacMan is sometimes missing a turn. For example: PacMan is in the very bottom left corner moving left to right. I press the up arrow in order to have pacman turn up the next open path. Sometimes pacman will skip the first open path and turn up the next one. Sometimes pacman will even skip the first 2 paths that are open for the "next direction" and go up the 3rd one. Other times, pacman will correctly go up the first available path. I do not think this is an issue with some paths being too small or having some other type of collider blocking entry. The paths that pacman skips are also paths that it won't skip other times. This is never a problem in areas where pacman collides with a wall and has to change direction. In this case, pacman will always go the correct way determined by the next direction set from user input. Do you have any insight into what the problem might be or how to fix it? Given the inconsistency, it seems like an issue with the update / fixed_update functions simply missing when the raycast determines an open path. Perhaps because Pacman moved right past the open path before the function got called.
Hi, I think you should add another box collider component to Pacman with trigger checked. and make some of customizations to occupied() method as following : this.transform.position -> boxCollider2D.bounds.center Vector2.one -> boxCollider2D.bounds.size. return hit != null; -> if(hit.collider != null) {return false} else {return true;} don't forget to assign boxcollider in Awake() as following: boxCollider2D = transform.GetComponent();
Loved this one. But for some reason on ghost home behavior, inky and clyde would bounce inside the house as they should, them they would move as intended to exit the house in an "L trajectory" but would snap back to their original position and move diagonally to the "Outside" game object. Gonna make some more debugging and see if I can find what is happening.
When I reach the scatter behavior part, my ghost starts colliding randomly with the walls and eventually it get stuck. I check and its position is moving in tiny decimals. What could be a solution to this problem?
@@JuanDavidArtal THANK YOU! Spent way too much time trying to debug that. For anyone still having this problem it was the Movement script on the Ghost_Base prefab
When I went to first test the movement script, Pacman did not stop when he hit the wall. I placed a square with a box collider in his way, and he did stop when he hit that. I went through the part where you built the walls to make sure my settings were all correct, and everything seems to be the same (including the collision matrix (collision is active between the "Pacman" and "Obstacles" layers) and the tile properties (collider type is set to "sprite")). Any idea why Pacman isn't colliding with the walls for me?
@@johnturner9786 Ah! Thanks for pointing that out! Seems to me that with the magic of editing, he could've put that explanation earlier in the video rather than letting people get confused, but whatever. At least I can get back to this once I finish my current project.
Couldn’t you turn off the tilemap renderer r the pellets tilemap since the GameObject has its own sprite? And wouldn’t that allow you to assign the sprite to the tile so you could see it in the pallet?
Great tutorial. I have found a problem. In open space, with only a few obstacles and not moving in a maze, the pacman can be offset, thus not actually being on the grid perfect ? I tried so many ways to fix this, but failed. I understand pacman fixes this problem by making everything confined into a maze, but would be great to see how u would tackle this. Maybe a more grid like snapping movement ?
If anyone is working in unity 2022 or above and your glitching out on the passages, move them slightly more in, not sure why this does this but it would probabalty have to do with any collider changes
yeah, it's possible and easier In fact i am using unity2017 so TileMap2D editor didn't work for me, so in that case I figured out a way to make my own level editor using Texture2D ...

You don't have to worry, there are thousands of tutorials in TH-cam that will help you make any game you have been dreaming of :) It doesn't matter if you're not good at programing, Unity is providing everything you need.
does anyone know why the ghosts defined in the "ghost prefabs" section don't move? If you change the layer from Ghost to Pacman they do. What can I do?
Your GhostChase has a bug, it won't go always towards Pac Man. To give an example, when pac man is in a top right corner and a ghost in chase mode has only an option to go left or go down it goes down. And then up again and down again etc etc. It makes the entire project obsolete because the most important script from this project isn't working.
1:44:30 my pacman's not eating the pellets and score's not increasing as it should, can somebody pls help me out, i don't know where the problem is and its bothering me soo much
Well, I wanna thank you for a good time. :D . Took me around seven hours to finish this tutorial but I had a blast doing it and learned a lot. Also everything works fine now after searching for my errors. Thanks for taking the time to create this tutorial. Now its time to add my ui, some music and also change the tile map, because thats the only thing I used from the Github version. Maybe I also add some animations because that part I skipped entirely becasue I didnt wanna have to draw animations for my little duck while following the video. Atleast its not walking up side down anymore when I go left. ^^. Cant wait to see in what kind of game my duck will end up again but in the meantime it will go back to space. Shooting asteroids was fun but shooting space ships sounds more fun.
I really appreciate these tutorials! I've been learning a lot better with them than I did with others that I'd used before. My only potential complaint is with using github for the file sharing. It works well enough, and perhaps I'm just not using it properly, but it doesn't seem to have a way to download folders. I didn't have much trouble individually downloading all the sprites for Asteroids, but for Pacman... well, it's a lot of clicking. I'll do it if I have to, but I'd really rather not. *edit* I figured it out. Apparently the green "Code" button (visible only while viewing the primary folder) is the download button. Seems like that could've been made more obvious, but oh well.
Green 'Code' button in the middle of the page allows you to download as a whole zip or just click on the individual folders, like you would in unity or windows etc. You can then download files individually as needed
Hi, I know this vid has been up for a while but I'm having issues with GhostHome. I basically copied everything down to the T but my Ghosts don't come outside of the home area at all. Do you know a solution?
For some reason when the ghost is on GhostChase mode it goes back and forth on a node, doesnt matter wheere I move Pacman and the target is indeed pacman, any help? my code seems to be the same as yours in the GhostChase class
With a node system already in play for the ghosts, is there a reason you didn't use this same node system for pacmans movements? Seems like it could have been much more lightweight?
Amazing tutorial, thanks so much :) Having some problems with the GhostChase though - when enabled, the ghost will just alternate between the two closest nodes, backwards and forwards, rather than chase Pacman? I've checked everything but can't find a solution!
I remember having this problem when I initially developed the game. I think there are a couple possible causes. 1. The ghost target transform might not be set correctly on the Ghost component. Normally speaking the ghost should be targeting pacman's transform. If for example, you set the target transform to some non-moving object this is an easy way to have the ghost ping-pong between nodes like yours is doing. This also seems relevant since the chase behavior uses that target position whereas not all other behaviors do. 2. It's possible for this to happen if the navigation nodes have only one available direction, although I think this would still happen for other ghost behaviors too. Assuming you are not doing a custom level, every navigation node should have at least 2 available directions. In your Node script, you can Debug.Log(availableDirections.Count) to verify that none of the nodes have a count of 1. If this is the problem, then make sure you have set your layers correctly, including the obstacle layer on your Node component.
Greetings! Thank you very much sir Zigurous for the tutorial video! May I ask a question? I followed the tutorial until 1:26:00 (The end of the player input part) however when I tested the game, pacman is not responding to any of my inputs. The movement is working like it is moving forward however the player input does not seem to work even though i followed the code and it compiled properly with no errors. Did I miss something? EDIT (As of March 2, 2022): I already found what the problem is. The circle collider of my pacman/player sprite is too small to recognize any boxcast on the obstacle on the grid. All I needed to do was resize the circle collider of pacman bigger until it exactly fits the grid and the input finally works.
Also, how do I change the collider type of my sprites? I do not see an option like that in my wall tiles (as they are png files of sprites) however I see an option llike that on rule tiles.
Hello Zigurous, great tutorial! I want to check what's the solution to Blinky not chasing Pacman after creating the GhostChase script. I have checked that the script is correct, added layers and tags correctly. Everything was working fine such as ghost changing direction when touched a node. However when it enters chase mode, it does not chase Pacman at all.
Hey guys, great video. I have completed it until the end and am currently in the middle of changing the code and game features to make it into a custom game. The question i have is how would i change the script for pacman to allow the character to face the same direction it is travelling assuming its not a circle i'm using? All i have done so far is change the sprite on the gameobject for pacman but my new sprite is flipping upside down when its going Left or more specifically whenever the z axis is - 180. I have had a look online and there are different suggestions for it such as rotation(lookat) but every code i'm seeing is using the getinputaxis horizontal and vertical and i dont want to mess with this script by starting a whole new movement system. Any help would be appreciated. thanks :)
Found a work around but i doubt this is efficient lol. Basically forcing unity to set the rotation and scale to make sure it faces the way i'm pressing. else if (Input.GetKeyDown(KeyCode.DownArrow)) { this.movement.SetDirection(Vector2.down); transform.localScale = new Vector3(1, 1, 1); transform.localRotation = Quaternion.Euler(0, 0, -90); } else if (Input.GetKeyDown(KeyCode.LeftArrow)) { this.movement.SetDirection(Vector2.left); transform.localScale = new Vector3(-1, 1, 1); transform.localRotation = Quaternion.Euler(0, 0, 0);
typically, you code for the "flip" in sprite renderer in inspector - so you import say facing "right" and leave it blank by default - then when you press "A" to go left, you set flip x/y to "active" ie. the checkbox becomes "checked" via boolean and then otherwise, it's then "off" again when not going left any more - but nice work on your replies cheers
another way for custom game - make custom "right facing" and "left facing" custom versions using free Krita drawing software - which has a "timeline" and you make say four frames - one version "left facing" the other version: "right facing" - then when you key input is "D" for right... you get the idea cheers
i am trying to solve a problem but i realy cant see any thing... i m doing everystep of the video and still there is an error...[error CS1061: 'GameObject' does not contain a definition for 'ResetState' and no accessible extension method 'ResetState' accepting a first argument of type 'GameObject' could be found]... i cant understand where is the problem with the ResetState on the 2:00:31 minute... please some one help its an emergency...
Using the built-in animation tools is completely fine too. Some people prefer doing it through code, others not. Neither is wrong. I personally find having a simple reusable script that I can pull into any project is easier and quicker to use, and it provides me more flexibility in some situations at runtime.
You have to download the full source from GitHub then drag the files into your project. In GitHub there is a green "Code" button with a "Download ZIP" link.
I would recommend using Unity 2021.1 or an even more recent version as it should come pre-installed with the 2D Tilemap Extras package. Otherwise you need to install it manually using the Package Manager window in Unity.
I started following this tutorial a couple days ago and I ran into a situation. After I did the movement script, when I test run it, I get a 'NullReferenceException' error that takes me to the GameManager script, specifically to the Start, NewGame, NewRound and ResetState voids. What exactly does that mean and how do I fix it? Because that causing my game to be unplayable
UPDATE: Got the 'NullReferenceException' error fixed, but now I have another issue. I'm all they way up to the Ghost Home part and when I run the game, the 3 ghosts do move as intended but when they trigger to scatter/chase mode they don't leave the box and stay there. How can I fix that? I checked my prefab assets and scripts and everything seems to be ok
Hello, I'm trying to make pacman games according to your tutorial on youtube, but I found a problem with the ghost prefabs, the ghost character doesn't appear on the game display and when played, but on the scene display it appears. please help me to solve the problem. Thank you.
It might be that the object is hidden behind something. You can try adjusting the sprite renderer component's "Sorting Layer" and "Order In Layer" properties, or you can even just change the z-axis position on the transform to set the order the objects render.
It'd be very helpful if you could answer. It seems I've repeated after you and also checked the code several times still I have a problem with GhostScatter because blinky stops after encountering the very first node. Layers, as I see, set properly, box collider is triggered. I can't understand where the problem is.
Maybe the ghost is not actually detecting collision with the node. I would put a Debug.Log(true) statement inside your OnTriggerEnter2D function in the GhostScatter script. If you see the log show up in your console then we know it is at least detecting collision which tells us the problem has to do with the logic instead. Some of the preconditions that have to be true for the logic to be executed is the behavior needs to be enabled, and the frightened behavior needs to be disabled. Double check those. Another issue could be within the Node script. Maybe the available directions aren't getting set correctly so after hitting the node the ghost doesn't know which way to go. You could Debug.Log the available directions to see what they are.
@@Zigurous Amazing video! Quick question. I am having the same issue with Blinky getting stuck upon colliding with the nodes but I have already gone through and debugged according to your suggestions above. The logic for determining the available direction works as intended but here are the two scenarios playing out right now: 1. Blinky collides with the first node. The randomly chosen direction is up and Blinky gets stuck. or 2. Blinky collides with the first node. The randomly chosen direction is left and Blinky continues on to the next node. Blinky then collides with the second node. The randomly chosen direction is down and Blinky gets stuck. It looks like what is happening is Blinky's direction is being set before being perfectly inline with the path its direction has been set to. When hitting the first node, it works if the direction is set to be left because it is already perfectly positioned on that path. However, if it changes paths then the direction is getting set too early and Blinky's body collides with the obstacles / walls. I feel like the solution would be similar to Pacman's movement where you set the direction, queue it and raycast to check for when Pacman can actually fit between the walls of the desired path. I am just not sure why this is a problem for me but it isn't something you had to address? EDIT: Fixed. I forgot to set the obstacle layer for the movement script on each ghost. Thanks again for a great tutorial!
i had the prefab ghostbase loaded with ghostscatter,ghosthome,ghostchase,ghostfrighten (ghostscatter being first) , when choosing initialbehavior for ghost, they do have all the 4 available option to choose ghostinky,ghostblinky,ghostpinky,ghostclyde all of the 4 are set ghostscatter as default, could u tell me how to change them , i wanted to allocate inky with initialbehavior with ghosthome rather then ghostscatter, thanks

This is one of those games where you could spend $1000 in quarters and still not get very good at it. The worst most difficult, though, was Asteroids. Trying to control the flight and rotating to shoot only with buttons and no joystick. Maddening.
You should try the old arcade Rip-Off game. Same type of flight control and shooting (but of enemies trying to steal a collection of cargo you're defending), but with increasingly difficult enemy ships and with the addition of a cooperative 2nd player who you could also accidentally shoot. lol
Great tutorial! Just checked the FAQs and comments but it doesn't look like this others have had this problem before.
I am having an issue where PacMan is sometimes missing a turn. For example: PacMan is in the very bottom left corner moving left to right. I press the up arrow in order to have pacman turn up the next open path. Sometimes pacman will skip the first open path and turn up the next one. Sometimes pacman will even skip the first 2 paths that are open for the "next direction" and go up the 3rd one. Other times, pacman will correctly go up the first available path.
I do not think this is an issue with some paths being too small or having some other type of collider blocking entry. The paths that pacman skips are also paths that it won't skip other times.
This is never a problem in areas where pacman collides with a wall and has to change direction. In this case, pacman will always go the correct way determined by the next direction set from user input.
Do you have any insight into what the problem might be or how to fix it?
Given the inconsistency, it seems like an issue with the update / fixed_update functions simply missing when the raycast determines an open path. Perhaps because Pacman moved right past the open path before the function got called.
Hi, I think you should add another box collider component to Pacman with trigger checked.
and make some of customizations to occupied() method as following :
this.transform.position -> boxCollider2D.bounds.center
Vector2.one -> boxCollider2D.bounds.size.
return hit != null; -> if(hit.collider != null) {return false} else {return true;}
don't forget to assign boxcollider in Awake() as following:
boxCollider2D = transform.GetComponent();
Loved this one. But for some reason on ghost home behavior, inky and clyde would bounce inside the house as they should, them they would move as intended to exit the house in an "L trajectory" but would snap back to their original position and move diagonally to the "Outside" game object. Gonna make some more debugging and see if I can find what is happening.
When I reach the scatter behavior part, my ghost starts colliding randomly with the walls and eventually it get stuck. I check and its position is moving in tiny decimals. What could be a solution to this problem?
I found the problem. It was that I forgot to assign the obstacle layer to one of the scripts in the ghosts (I don't remember which one)
@@JuanDavidArtal THANK YOU! Spent way too much time trying to debug that. For anyone still having this problem it was the Movement script on the Ghost_Base prefab
Cool
This tutorial helped me so much!! Could you explain how to make different IA for the other ghosts?
When I went to first test the movement script, Pacman did not stop when he hit the wall. I placed a square with a box collider in his way, and he did stop when he hit that. I went through the part where you built the walls to make sure my settings were all correct, and everything seems to be the same (including the collision matrix (collision is active between the "Pacman" and "Obstacles" layers) and the tile properties (collider type is set to "sprite")). Any idea why Pacman isn't colliding with the walls for me?
I was having the exact same issue. Adding a Tilemap Collider 2D to the Walls seemed to work. He mentions the oversight at 1:17:45.

Couldn’t you turn off the tilemap renderer r the pellets tilemap since the GameObject has its own sprite? And wouldn’t that allow you to assign the sprite to the tile so you could see it in the pallet?
Yes, you are right. That is a good suggestion I will keep in mind if I run into that same problem again.
Great tutorial. I have found a problem.
In open space, with only a few obstacles and not moving in a maze, the pacman can be offset, thus not actually being on the grid perfect ?
I tried so many ways to fix this, but failed.
I understand pacman fixes this problem by making everything confined into a maze, but would be great to see how u would tackle this.
Maybe a more grid like snapping movement ?
If anyone is working in unity 2022 or above and your glitching out on the passages, move them slightly more in, not sure why this does this but it would probabalty have to do with any collider changes
Question, why draw out the tile? Wouldn't it be easier to just import a whole scene as an image? Or is that not done on video games?
yeah, it's possible and easier

does anyone know why the ghosts defined in the "ghost prefabs" section don't move? If you change the layer from Ghost to Pacman they do. What can I do?
Your GhostChase has a bug, it won't go always towards Pac Man. To give an example, when pac man is in a top right corner and a ghost in chase mode has only an option to go left or go down it goes down. And then up again and down again etc etc. It makes the entire project obsolete because the most important script from this project isn't working.

Well, I wanna thank you for a good time. :D . Took me around seven hours to finish this tutorial but I had a blast doing it and learned a lot. Also everything works fine now after searching for my errors. Thanks for taking the time to create this tutorial.
Now its time to add my ui, some music and also change the tile map, because thats the only thing I used from the Github version. Maybe I also add some animations because that part I skipped entirely becasue I didnt wanna have to draw animations for my little duck while following the video. Atleast its not walking up side down anymore when I go left. ^^.
Cant wait to see in what kind of game my duck will end up again but in the meantime it will go back to space. Shooting asteroids was fun but shooting space ships sounds more fun.
I appreciate you taking the time to go through the entire tutorial. I'm glad you learned a lot from it!
I really appreciate these tutorials! I've been learning a lot better with them than I did with others that I'd used before. My only potential complaint is with using github for the file sharing. It works well enough, and perhaps I'm just not using it properly, but it doesn't seem to have a way to download folders. I didn't have much trouble individually downloading all the sprites for Asteroids, but for Pacman... well, it's a lot of clicking. I'll do it if I have to, but I'd really rather not. *edit* I figured it out. Apparently the green "Code" button (visible only while viewing the primary folder) is the download button. Seems like that could've been made more obvious, but oh well.
You can just download the whole project from git up as a zip and then pick and choose what you want from it
Green 'Code' button in the middle of the page allows you to download as a whole zip
or just click on the individual folders, like you would in unity or windows etc. You can then download files individually as needed

Hi, I know this vid has been up for a while but I'm having issues with GhostHome. I basically copied everything down to the T but my Ghosts don't come outside of the home area at all. Do you know a solution?
For some reason when the ghost is on GhostChase mode it goes back and forth on a node, doesnt matter wheere I move Pacman and the target is indeed pacman, any help? my code seems to be the same as yours in the GhostChase class
how do I get pacman to work on my android can't seem to get buttons on screen to work?
With a node system already in play for the ghosts, is there a reason you didn't use this same node system for pacmans movements? Seems like it could have been much more lightweight?
Amazing tutorial, thanks so much :) Having some problems with the GhostChase though - when enabled, the ghost will just alternate between the two closest nodes, backwards and forwards, rather than chase Pacman? I've checked everything but can't find a solution!
I remember having this problem when I initially developed the game. I think there are a couple possible causes.
1. The ghost target transform might not be set correctly on the Ghost component. Normally speaking the ghost should be targeting pacman's transform. If for example, you set the target transform to some non-moving object this is an easy way to have the ghost ping-pong between nodes like yours is doing. This also seems relevant since the chase behavior uses that target position whereas not all other behaviors do.
2. It's possible for this to happen if the navigation nodes have only one available direction, although I think this would still happen for other ghost behaviors too. Assuming you are not doing a custom level, every navigation node should have at least 2 available directions. In your Node script, you can Debug.Log(availableDirections.Count) to verify that none of the nodes have a count of 1. If this is the problem, then make sure you have set your layers correctly, including the obstacle layer on your Node component.
Greetings! Thank you very much sir Zigurous for the tutorial video! May I ask a question? I followed the tutorial until 1:26:00 (The end of the player input part) however when I tested the game, pacman is not responding to any of my inputs. The movement is working like it is moving forward however the player input does not seem to work even though i followed the code and it compiled properly with no errors. Did I miss something?
EDIT (As of March 2, 2022): I already found what the problem is. The circle collider of my pacman/player sprite is too small to recognize any boxcast on the obstacle on the grid. All I needed to do was resize the circle collider of pacman bigger until it exactly fits the grid and the input finally works.
Also, how do I change the collider type of my sprites? I do not see an option like that in my wall tiles (as they are png files of sprites) however I see an option llike that on rule tiles.
where did u apply the heritage and polymorphisme ( concepts of oriented-object programming ) in the code
Hello Zigurous, great tutorial! I want to check what's the solution to Blinky not chasing Pacman after creating the GhostChase script. I have checked that the script is correct, added layers and tags correctly. Everything was working fine such as ghost changing direction when touched a node. However when it enters chase mode, it does not chase Pacman at all.
Hey guys, great video. I have completed it until the end and am currently in the middle of changing the code and game features to make it into a custom game. The question i have is how would i change the script for pacman to allow the character to face the same direction it is travelling assuming its not a circle i'm using? All i have done so far is change the sprite on the gameobject for pacman but my new sprite is flipping upside down when its going Left or more specifically whenever the z axis is - 180. I have had a look online and there are different suggestions for it such as rotation(lookat) but every code i'm seeing is using the getinputaxis horizontal and vertical and i dont want to mess with this script by starting a whole new movement system. Any help would be appreciated. thanks :)
Found a work around but i doubt this is efficient lol. Basically forcing unity to set the rotation and scale to make sure it faces the way i'm pressing.
else if (Input.GetKeyDown(KeyCode.DownArrow))
{
this.movement.SetDirection(Vector2.down);
transform.localScale = new Vector3(1, 1, 1);
transform.localRotation = Quaternion.Euler(0, 0, -90);
}
else if (Input.GetKeyDown(KeyCode.LeftArrow))
{
this.movement.SetDirection(Vector2.left);
transform.localScale = new Vector3(-1, 1, 1);
transform.localRotation = Quaternion.Euler(0, 0, 0);
Using negative scale is a great workaround, simple and no silly code. Nice
typically, you code for the "flip" in sprite renderer in inspector - so you import say facing "right" and leave it blank by default - then when you press "A" to go left, you set flip x/y to "active" ie. the checkbox becomes "checked" via boolean and then otherwise, it's then "off" again when not going left any more - but nice work on your replies cheers
another way for custom game - make custom "right facing" and "left facing" custom versions using free Krita drawing software - which has a "timeline" and you make say four frames - one version "left facing" the other version: "right facing" - then when you key input is "D" for right... you get the idea cheers

Do we really need to reinvent a sprite animator in the form of a script when having an animation tool built in Unity?
Using the built-in animation tools is completely fine too. Some people prefer doing it through code, others not. Neither is wrong. I personally find having a simple reusable script that I can pull into any project is easier and quicker to use, and it provides me more flexibility in some situations at runtime.

Im stuck on the part where your making your own tile i do not see 2D tilemap extras and i can find a way around it (new to making games)
I would recommend using Unity 2021.1 or an even more recent version as it should come pre-installed with the 2D Tilemap Extras package. Otherwise you need to install it manually using the Package Manager window in Unity.

make a tutorial to add new ghosts and multi pacmans
I started following this tutorial a couple days ago and I ran into a situation. After I did the movement script, when I test run it, I get a 'NullReferenceException' error that takes me to the GameManager script, specifically to the Start, NewGame, NewRound and ResetState voids.
What exactly does that mean and how do I fix it? Because that causing my game to be unplayable
UPDATE: Got the 'NullReferenceException' error fixed, but now I have another issue. I'm all they way up to the Ghost Home part and when I run the game, the 3 ghosts do move as intended but when they trigger to scatter/chase mode they don't leave the box and stay there.
How can I fix that? I checked my prefab assets and scripts and everything seems to be ok

Hello, I'm trying to make pacman games according to your tutorial on youtube, but I found a problem with the ghost prefabs, the ghost character doesn't appear on the game display and when played, but on the scene display it appears. please help me to solve the problem. Thank you.
It might be that the object is hidden behind something. You can try adjusting the sprite renderer component's "Sorting Layer" and "Order In Layer" properties, or you can even just change the z-axis position on the transform to set the order the objects render.
@@Zigurous thankyou! I've been able to solve the problem. but, how to make the score and the number of lives of the pacman?
It'd be very helpful if you could answer. It seems I've repeated after you and also checked the code several times still I have a problem with GhostScatter because blinky stops after encountering the very first node. Layers, as I see, set properly, box collider is triggered. I can't understand where the problem is.
Maybe the ghost is not actually detecting collision with the node. I would put a Debug.Log(true) statement inside your OnTriggerEnter2D function in the GhostScatter script. If you see the log show up in your console then we know it is at least detecting collision which tells us the problem has to do with the logic instead.
Some of the preconditions that have to be true for the logic to be executed is the behavior needs to be enabled, and the frightened behavior needs to be disabled. Double check those.
Another issue could be within the Node script. Maybe the available directions aren't getting set correctly so after hitting the node the ghost doesn't know which way to go. You could Debug.Log the available directions to see what they are.
@@Zigurous Thank you! I'll try
@@Zigurous Amazing video! Quick question. I am having the same issue with Blinky getting stuck upon colliding with the nodes but I have already gone through and debugged according to your suggestions above.
The logic for determining the available direction works as intended but here are the two scenarios playing out right now:
1. Blinky collides with the first node. The randomly chosen direction is up and Blinky gets stuck.
or
2. Blinky collides with the first node. The randomly chosen direction is left and Blinky continues on to the next node. Blinky then collides with the second node. The randomly chosen direction is down and Blinky gets stuck.
It looks like what is happening is Blinky's direction is being set before being perfectly inline with the path its direction has been set to. When hitting the first node, it works if the direction is set to be left because it is already perfectly positioned on that path. However, if it changes paths then the direction is getting set too early and Blinky's body collides with the obstacles / walls.
I feel like the solution would be similar to Pacman's movement where you set the direction, queue it and raycast to check for when Pacman can actually fit between the walls of the desired path. I am just not sure why this is a problem for me but it isn't something you had to address?
EDIT: Fixed. I forgot to set the obstacle layer for the movement script on each ghost. Thanks again for a great tutorial!
