Official 2D Roguelike: Q&A

Hi Atre, where you've got your void OnDisable, make sure that you're unsubscribing the event (rather than subscribing):

Code (CSharp):

1. void OnDisable()
2. {
3.         SceneManager.sceneLoaded -= OnLevelFinishedLoading;
4. }
5.  

This may fix your issue. I 'think' it's trying to look for game objects that have already been destroyed once the script becomes disabled perhaps? Give it a shot anyway, I could be quite easily wrong.

 

Question on Roguelike.

I'm building a similar 2d game, and one thing I can't figure out: how does the Roguelike tutorial move only one tile at a time? I don't see anything that forces it to move exactly 32 pixels, the # in each tile. The linecast just stretches to the next collider as far as I can tell, so there shouldn't be anything stopping the player from moving several tiles or half a tile or whatever while its their turn.

 

I may not be explaining this properly, as I'm just learning it too, but I think the move code moves it one "Unity" game unit, up, down, left, or right. When you imported your original spritesheet there was a setting that specified how many pixels (32) equal 1 unit. If you click on the spritesheet in your assets/sprites folder, then look at the properties editor you should see this.

Again, I think this is what's happening but I could be wrong

 

Hi. Hoping someone here can help me, because I'm pulling my hair here.

I'm on part 11 of the tutorial, but at the end, where i'm supposed to test the game and see my character destroy walls and pick up food, he just walks straight over them. He's not even stopped by the outer walls. He can still move through the exit to the new level, though.

I've checked everything I can think off - tags, layers, scripts. It's all identical to both the videos and the "completed" folder, save for the change in how the scene is loaded on restart. Does anyone know what might be wrong?

A couple of pictures:

 

In MovingObject.cs what do you have in your AttemptMove <T> () method? Also what do you have in your Player.cs script for OnCantMove<T>() method? These are the methods that determine how to handle the component in the Wall prefabs. Here's mine:

MovingObject.cs

Code (CSharp):

1. protected virtual void AttemptMove <T> (int xDir, int yDir)
2.         where T : Component
3.     {
4.         RaycastHit2D hit;
5.         bool canMove = Move(xDir, yDir, out hit);
6.  
7.         if (hit.transform == null)
8.             return;
9.  
10.        T hitComponent = hit.transform.GetComponent<T>();
11.  
12.      
13.         if (!canMove && hitComponent != null)
14.             OnCantMove(hitComponent);
15.     }

Player.cs

Code (CSharp):

1. protected override void OnCantMove<T>(T component)
2.     {
3.         Wall hitWall = component as Wall;
4.         hitWall.DamageWall(wallDamage);
5.         animator.SetTrigger("playerChop");
6.     }

For the OuterWall prefabs, it should do nothing but prevent movement in that direction, but for Wall prefabs it will apply the hit logic and "playerChop" animation until the Wall has no damage left.

 

Code (CSharp):

1. protected virtual void AttemptMove<T>(int xDir, int yDir)
2.         where T : Component {
3.         RaycastHit2D hit;
4.         bool CanMove = Move(xDir, yDir, out hit);
5.         if (hit.transform == null)
6.             return;
7.         T hitComponent = hit.transform.GetComponent<T>();
8.         if (!CanMove && hitComponent != null)
9.             OnCantMove(hitComponent);
10.     }

Code (CSharp):

1. protected override void OnCantMove<T>(T component) {
2.         Wall hitWall = component as Wall;
3.         hitWall.DamageWall(wallDamage);
4.         animator.SetTrigger("playerChop");
5.     }

Those are mine. I can't spot the difference.

 

do ALL your walls and food objects have the layer set to BlockingLayer?

You said the exit works, but the player just walks over the food and soda and nothing happens? So whats different about the exit v.s. the food or soda? The three prefabs are handled in the same block of code so if they're setup the same they should each invoke a reaction. Is there anything different in the prefabs of the three that you can see?

also, i'm sure there's a better way to do this - but i'm just learning as well, but in order to see if the game walks through a portion of code i add:
debug.Log("test ....");
and check the console output tab to see if it gets printed. Its a good way to see if the game makes runs through that block of code or if it's skipping it for some reason.

Code (CSharp):

1.  
2. private void OnTriggerEnter2D(Collider2D other)
3.     {
4.         if (other.tag == "Exit")
5.         {
6.             Invoke("Restart", restartLevelDelay);
7.             enabled = false;    
8.         }
9.         else if (other.tag == "Food")
10.         {
11.             food += pointsPerFood;
12.             foodText.text = "+" + pointsPerFood + " Food: " + food;
13.             SoundManager.instance.RandomizeSfx(eatSound1, eatSound2);
14.             other.gameObject.SetActive(false);
15.         }
16.         else if (other.tag == "Soda")
17.         {
18.             food += pointsPerSoda;
19.             foodText.text = "+" + pointsPerSoda + " Food: " + food;
20.             SoundManager.instance.RandomizeSfx(drinkSound1, drinkSound2);
21.             other.gameObject.SetActive(false);
22.         }
23.     }
24.  

 

No, Soda/Food is in the default layer along with Exit, just like the prefabs in the "Completed" folder.

As for the debug logging, I'll try it in the morning. Thanks for now though!

 

Thanks JR! I believe that is what I was missing!

 

Hello there,

I have been following the tutorial using Unity 5.5 (following the guidelines in the Upgrade guide PDF) with no problem until the step where I added the UI, then when I wanted to try, the game started at Day 2. I tried intializing the level to 0 instead of one, now the game starts at Day 1 but immediately after the first level I jump to Day 3 and foodCount gets set to 0 (thus after I try to move, I get the GameOver message "After 3 days, you starved."

I added some `Debug.Log` in the function that calls `instance.level++`

void OnLevelFinishedLoading(Scene scene, LoadSceneMode mode) {
Debug.Log ("OnLevelFinishedLoading");
//Add one to our level number.
instance.level++;
//Call InitGame to initialize our level.
instance.InitGame();
}​

That's when I realized the function `OnLevelFinishedLoading` was called once when the game starts then twice after each level. How do I prevent that ?

EDIT:

After putting GameManager.instance.playerFood = food; in Player function "Restart" instead of OnDisable(), the food problem got away (now that I think of it, do we ever disable the player ?). So I could play further in the game, the only level that gets skipped is level 2. So I get "Day 1", "Day 3", "Day 4", "Day 5", ... I still have no idea why OnLevelFinishedLoading gets called twice after I finish level 1

 

I had this problem as well, as did a few others in this thread.

This is what i did to fix:
Remove the InitGame(); line from the Awake() method of GameManager. It's getting called there, and also in OnLevelFinishedLoading() at the start of the game which is why it jumps to level 2.

also, change this function to the following

Code (CSharp):

1.  void OnLevelFinishedLoading(Scene scene, LoadSceneMode mode)
2.     {
3.         level++;
4.         InitGame();
5.     }

and at the top of GameManager initialize level=0;

 

Hi, I'm close to finishing but getting some compilation errors:

54.  
55.         animator.SetTrigger ("enemyAttack");
56.     }
57.  
58. }
59.  

I've tried replacing it with the completed version, same error. Any help would be appreciated on this.

UPDATE: Solved using notes in '2D Roguelike Upgrade Guide 5x.pdf' in assets folder.
UPDATE 2: This has not actually solved my issue, just mitigated a further one. Still getting the same two errors.
UPDATE 3: Solved, Player prefab was not tagged 'Player'. Now only have a small problem where player picks up soda but not food...
UPDATE 4: Also solved, ' else if (other.tag == "Food")' line in Player.cs did not have 'Food' capitalized. Success!

 

Hey, I am a new to Unity and programming, so I can not figure out what is going on with my game. I have followed the tutorial as closely as I can, and everything is working fine so far, except the exit does not spawn in on the second day. Everything else seems to work fine.

Here is the error I get:
ArgumentException: The thing you want to instantiate is null.

When I double click on the error, it leads me to this line of code:
Instantiate (tileChoice, randomPosition, Quaternion.identity);

Anybody know how to fix it? Thanks for any help.

 

In my Game when the player dies doesn't restar the level. I opened the completed project and it doesn't open either. What should i do?

Hello! I'm having a strange problem: when i restart the scene because of the "exit" the 'playerFoodPoints' of my GameManager istance go to zero. All the remaining values of the instance don't change. I suppose it's something related to the "dontDestroyOnLoad". Any idea? ^^

I can easily solve the problem with a static int variable skipping the instance but i'd like to understand the behaviour described above.

Thanks!

 

Farlakko check out http://answers.unity3d.com/questions/1139046/fix-for-2d-roguelike-no-restart-and-jumping-scenes.html

I hope the pdf with the update for SceneManager can be updated to include the firstrun boolean as anybody who follows it will run into the level skipping and 0 food bug, I just wasted 2 hours on it

 

This solved the problem, thanks a lot !

So if I understand correctly, I was calling the OnLevelFinishedLoading from the start. However I don't understand anyway what caused the bug, do you?

 

Hi Matt,
Thank you very much for this tutorial, I am very new to Unity, so forgive me if I ask obvious question.
I follow the tutorial in Unity v 5.5.2. I feel I learned very much from your work.
However, I have found the problem which I cannot manage. In order to describe it you need to watch the video I have attached. In this video You see that when Player takes Food, or Soda, or interacts with walls, there is changing the Outer Walls in position of the Column 0.
Do you have any Ideas what could be the cause of this bug and how to fix it.

Thank you for your help in adwance

Im not sure where to begin on sharing my scripts. I just finished up episode 11 and the issue Im having is that my player is not picking up any items or able to interact with the exit. I get no errors. I also put debug.log statements in the OnTriggerEnter2D function in the "Player" script. I get no console output whenever I walk over these items. Is trigger is checked on items, Player character has a rigid body and is kinematic. Tags are correct, "Food", "Soda", "Exit". The are set to default layer with the "Items" sorting layer. Hopefully someone will be able to assist me on this one.

****EDIT****
Nevermind I figure out the issue. I had "private void OnTriggerEnter2d" rather than 2D

 

is that in the actual compiled game or is that when playing the game inside the Unity editor?

 

Next stupid questions.

1:
Instead of every wall having 3 hit points, I want them to have a random range of hp, and I'm thinking that the code should be
public int hp = Random.Range(1,5)
but I wanted to check with you guys and see if this was correct.

2:
When the player hits the wall, again I want a random ammount of damage to be done, and I'm thinking that it should be:

public int wallDamage = Random.Range(1,3)
and again, I wanted to check this.

And 3:
I would like to display the amount of damage done to the wall with each hit, but I just get errors when trying to use the same code that's used for displaying the food points when food is picked up, so was looking for some help. The code doesn't need to be public, so I tried using a private variable - but got no where. C# and I are not getting along well, unfortunately. I'm experienced with C but C# is kicking me to the curb and Unity is helping.

 

Thank you for your answer,
this happens in both situation, i.e. in Unity Editor and after compilation, in the compiled program the number of that places is bigger and concerns all walls around the game board.

I would redo all your animations and tiles. It sounds like you've gotten something mixed up. And make sure that you didn't accidentally name 2 things the same somehow.

 

Hey so everything is working perfectly except for one minor detail. If I hold down an arrow key between scenes loading (or levels loading whatever you prefer to call it), the player is able to move exactly one block in the next scene, but no more than that. Any idea what might be causing this?

 

I am on section 5 of the tutorial. It tells me to drag my prefabs into my BoardManager script after I add it to my GameManager gameitem. I have copied the tutorial word for word, but there is no place for me to drag my prefabs into. I cannot run anything as it gives me a compile error.

 

I am following the tutorial and am at the section described as assigning variables to the Board Manager script. I've assigned the prefabs to the Board Manager script and tested, but only Outer Wall 1-3, Floor 1-8 and Exit are showing. Enemy 1 and 2, Wall 1-8, Food and Soda don't show up. I wondered whether I had the wrong sorting layer for these, but have checked it and they seem to be right. Any advice would be appreciated, thanks.

 

If you've put enemies, food, and soda in your prefabs, and deleted them from the project, they won't show up in the game until the script loads them. Enemies don't show up on the first level, ever. Your food or soda objects will show up on level 1, but not necessarily both of them. It's random. And they're only going to show up when the game is running.

But your inner walls should be showing up.

Do this:

Run the game, then look at the console tab. Are there any errors?

 

you're still building the game. Don't hold the arrow key down. Wait till the game is completely built then see if its still happening.

 

1. you need to go through the earlier tutorials for space shooter and roll the ball.

2. You need to create a prefabs folder under the assets folder on the project tab, and put your prefabs in that folder.

 

Hello, I am having only two issues in the tutorial for the 2DRougelike game from Unity (I have just finished part 11 the Enemy Animator Video).

1. My When my player moves onto the food and/or the Soda tiles, the food and/or Soda does not get "picked up".
2. In my scripts (even tough I followed the tutorial to the letter), states the variable 'hit' is declared but never used, Is this a issue?

Any help will be greatly appreciated. Thank You.

P.S. I have found this tutorial to be wonderful and informative I am really enjoying it (I am using Windows 10 if that makes any difference).

 

Did you forget to set your food and soda items as triggers?

 

Hello CrystalWixard321,

I have fixed the issue it was just a bug in the scripting. However, I am having three different issues now.

1. The black screen that is suppose to appear at the start, end and between levels does not cover the games screen fully.
2. After my player dies the game does not automatically restart.
3. The only way I can close the game is from closing it from right clicking it in the system tray of my computer and clicking close.

Any help will be greatly appreciated. Thank You.

 

I have been following the tutorial, and it has been going quite well up to the point where I added the ui elements.

I can display Day 1 correctly, and the food counter displays correctly.

Unfortunately the ui image does not disappear. So the screen remains black.

The food counter is fine, and I can move around the screen, pick up soda, get hurt by enemies, even move to the next level. The Day 2 text displays.

I am just doing this all in total darkness. Looking in the inspector the image element is greyed out after the Day text disappears, leading me to believe the SetActive method is being called and inactivating the image. But it doesn't go away.

The layer is set to UI.

Any suggestions for how to fix this? Had a lot of fun so far.

 

Hi RedEye:

>1. The black screen that is suppose to appear at the start, end and between levels does not cover the games screen fully.

Go back through the UI training video. You've missed several steps.

>2. After my player dies the game does not automatically restart.

No, and it won't. But you can go through the roll the ball tutorial and there are instructions in it to add a restart button in that the player can click.

>3. The only way I can close the game is from closing it from right clicking it in the system tray of my computer and clicking close.

when in Unity or when playing in a build from windows? If it's the windows build, no, you can't close it. You can alt-tab to get to a different window, or you can add in a restart/quit menu. That's not something that's included (unfortunately) in the tutorial.

 

I suggest you re-watch the UI tutorial video and double-check everything.

 

I rewatched the video again, paying special attention to anything that might cause a wrong result but not be caught by the compiler (I come from a C/C++ background so I'm used to stumbling over my own silliness in this way).

The only thing that I could see that might cause a problem is that since I am using version 5.3 the OnSceneLoaded function could be potentially deprecated and not work.

I followed then the UpgradeGuide and got an error that "sceneLoaded" was not defined in the package.

Sometimes an error is progress for me, but I"m not sure if this is one of those cases.

 

Don't feel bad. I hate C#. I much prefer C. My own background is programming MUDs.

>I followed then the UpgradeGuide and got an error that "sceneLoaded" was not defined in the package.

You need to add using UnityEngine.SceneManagement; to your includes in the player script

You didn't state what tutorial video you're on, but under section 4 he starts talking about adding in the UI elements, how to position text such as food points, what layer to put the various elements (including the black image that displays between level) and so on. What step are you on?

 

OMG I looked everywhere. Stupid thing I didn't notice. Thanks Steerpike.

 

Well maybe some people wondered how have the screen properly size for portrait and landscape on mobile.
Here my code for the Loader script. Modified it so now the camera size change to fit any screen.
And also update if you rotate the screen.
Also make sure the Canvas->Canvas Scaler->UI Scale Mode: is set to 'Scale With Screen Size' so the Texts scales properly

Code (CSharp):

1. using UnityEngine;
2.  
3. public class Loader : MonoBehaviour {
4.  
5.     public GameObject gameManager;
6.  
7. #if UNITY_IOS || UNITY_ANDROID || UNITY_WP8 || UNITY_IPHONE
8.     private float sW;
9.     private float sH;
10. #endif
11.  
12.     void Awake()
13.     {
14.         if (GameManager.instance == null)
15.         {
16.             Instantiate(gameManager);
17.         }
18.     }
19.  
20. #if UNITY_IOS || UNITY_ANDROID || UNITY_WP8 || UNITY_IPHONE
21.     public void Update()
22.     {
23.         sW = Screen.width;
24.         sH = Screen.height;
25.      
26.         if (Screen.width < Screen.height)
27.         {
28.             Camera.main.orthographicSize = (5f / (sW / sH));
29.         }
30.         else if (Screen.width > Screen.height)
31.         {
32.             Camera.main.orthographicSize = 5;
33.         }
34.     }
35. #endif
36. }

I am new to scripting and I am having this error when I finish the level and step into the exit sign. I followed the supplement pdf for the GameManager script.

NullReferenceException: Object reference not set to an instance of an object
Completed.GameManager.OnSceneLoaded (Scene arg0, LoadSceneMode arg1) (at Assets/_Complete-Game/Scripts/GameManager.cs:69)
UnityEngine.SceneManagement.SceneManager.Internal_SceneLoaded (Scene scene, LoadSceneMode mode) (at C:/buildslave/unity/build/artifacts/generated/common/runtime/SceneManagerBindings.gen.cs:245) I did not mistakenly use any of the completed scripts so I don't know why it is referring to (at Assets/_Complete-Game/Scripts/GameManager.cs:69)

 

Everything works fine until ( except starts on Day 2), food walls, enemies, hit points when enemies attack... I even spent the day starting from scratch.... I step into the exit..... then I get exception... I know that Unity just got upgraded and the supplement has something to do with it...

 

I put // in front of InitGame in Awake() and now she works ! Thanks...I don't know why you start at level 2 though..I have private int level = 2... and my game starts at 1..?

 

Hi,

I'm having trouble after "2D Roguelike 11 of 14 : Enemy Animator Controller" tutorial. I launch the game and the first level is fine. When I go to the exit the next level starts, but I can only move once, and even in to the blocking walls.

Thanks, you pointed me to the solution

 

Hi all,
I see this thread is still active, awesome!
Let's say I want to replace floor tiles and player sprites with some of my own work. Is there anyway around the fact that it is all 32x32 pixels? If I add my own artwork it keeps its real size (downsizing is not an option because I am not into pixel art) but positions it on the grid as if it is the 32x32.

So my solution would be to have the boardmanager.cs lay things out in a way that there is enough room for bigger sprites but still have all the player movements etc. work properly. The problem is, I don't know how.

In case that isn't clear enough, what would be needed to replace the 32x32 floor sprites with let's say, 150x150 floor sprites without messing everything up since simple drag and drop to the Sprite Renderer will do this.

Any advice, pointers or general info would be much appreciated and thanks in advance already!

PS. I followed the tutorial without trouble but am a beginner with Unity and new to C#. I read up on it a bit and have some light/moderate experience in JS, TCL and HTML.

Hi guys
I have a question about the Script BoardManager.cs (in the Complete-Game Version).

why should i use a Vector3 in line 41 ?

this line:

Code (CSharp):

1. private List <Vector3> gridPositions = new List <Vector3> ();    //A list of possible locations to place tiles.

Could i use a Vector2 as well ?


And in line 114

Code (CSharp):

1. int objectCount = Random.Range (minimum, maximum+1);

Why should i coose maximum "+1"?

Can anybody please explain me why we should add 1 to maximum ?



Great Videos
Thanks

I too had the level skipping by 2 counts and starting at level 2 (then 4,6,8,...)
Reading the comments saw the solution so excellently described JRWidley by this post (#912).
