Official 2D Roguelike: Q&A

You're missing a bunch of spaces. It should be "void BoardSetup" and "GameObject toInstantiate" and "GameObject instance"

Please double check your code and make sure you are inserting spaces when necessary.

hey Andrew,

Glad you found this helpful. Depending on the size of your game you probably will want to load and unload the scenes. There are a number of ways to do this but one way would be to save and reload them from disk. I would look at Mike Geig's live session here: https://unity3d.com/learn/tutorials...ining-archive/persistence-data-saving-loading

Specifically he has a section on data serialization which you can use to serialize a class as binary data and then write and read that. In a personal project of mine I'm using that basic structure to write and read data about player unlocks and other data between sessions and I think it could work for your level data as well. I would just have a class that holds the level layout in an array or whatever you choose and then store that. Note that I haven't tested this approach, it's just an idea. Another option to look into would be JSON which I know people like but I don't personally have experience with.

 

The asset message appears again, and it doesn't contain the 'accept' button when I clicked download.
Maybe I'm doing this wrong. would someone at least give me a different download of the same assets and how to download it?

 

Thanks again Matt! I'll check it out, looks exactly what I need. If I come up with some clean code patterns I'll post them back in to the forum.
Cheers,
Andrew.

 

I'm on part 13 of the tutorial. I managed to make everything functional except for one thing. It is true that my enemy moves, but he only moves to the left or down-not up or right. Some code is below.

Edit: Never mind. I set the transform.position of the enemy to an integer form. I have no idea why I did that.

Enemy:

Code (CSharp):

I have just finished this tutorial. It works perfectly fine at the Unity editor but when I build it, things go strange. I start at level 2 and can't move. Any help out there?

EDIT: Also, the enemy gets stuck in a wall. What is going on?

 

Anybody have that error:
It is after 9 lesson.

 

I also have another problem. When I try to build for IOS, I see that there is no module downloaded. I can't build my game for IOS.

 

Hello,
Thanks for the good tutorial. I've been following the tutorial step by step so as to try understand the thought process of making this game. I've come across one error while following your steps and I would like to resolve it before moving forward. I am currently using version 5.3.2f1 of Unity, currently there is an update to version 5.3.4f1 but I don't want to upgrade till I resolve the error. The error happened after writing the Game Manager of the game, when creating the game loader. After following all the steps in the video and after creating the Loader script, Unity gives me this error

This is the code of the Loader

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Loader : MonoBehaviour {
5.  
6.     public GameObject gameManager;
7.  
8.     void Awake ()
9.     {
10.         if (GameManager.instance == null)
11.             Instantiate (gameManager);
12.     }
13. }

I have done videos 1 to 5 without any editing or changing of the scripts or steps. I checked the loader code that is presented under the video number 5 and I can see there is more code added but in the video it is stated that the rest of the loader script will be presented in a later video so I didn't add the extra lines to my current code. Please tell me what I did wrong and what I can do to fix this error and move on. I have no experience coding in C# sorry.

This is the GameManager code

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. namespace Completed
5. {
6.     using System.Collections.Generic;       //Allows us to use Lists.
7.  
8.     public class GameManager : MonoBehaviour
9.     {
10.  
11.         public static GameManager instance = null;              //Static instance of GameManager which allows it to be accessed by any other script.
12.         private BoardManager boardScript;                       //Store a reference to our BoardManager which will set up the level.
13.         private int level = 3;                                  //Current level number, expressed in game as "Day 1".
14.    
15.         //Awake is always called before any Start functions
16.         void Awake()
17.         {
18.             //Check if instance already exists
19.             if (instance == null)
20.  
21.                 //if not, set instance to this
22.                 instance = this;
23.  
24.             //If instance already exists and it's not this:
25.             else if (instance != this)
26.  
27.                 //Then destroy this. This enforces our singleton pattern, meaning there can only ever be one instance of a GameManager.
28.                 Destroy(gameObject);  
29.  
30.             //Sets this to not be destroyed when reloading scene
31.             DontDestroyOnLoad(gameObject);
32.  
33.             //Get a component reference to the attached BoardManager script
34.             boardScript = GetComponent<BoardManager>();
35.  
36.             //Call the InitGame function to initialize the first level
37.             InitGame();
38.         }
39.  
40.         //Initializes the game for each level.
41.         void InitGame()
42.         {
43.             //Call the SetupScene function of the BoardManager script, pass it current level number.
44.             boardScript.SetupScene(level);
45.  
46.         }
47.  
48.  
49.  
50.         //Update is called every frame.
51.         void Update()
52.         {
53.  
54.         }
55.     }
56. }

I have a feeling it might be the latest update to Unity, but a lot of keywords won't highlight like they usually do. things like GameObject[], Quaternion and things like those keywords will not highlight! I also feel like it's something at the top, one of the using code segments. Please help! thank you!

 

Well, it would be more helpful if you would post the errors that your compiler is telling you.

 

Sorry, I forgot to do that. But I spent more time looking at my code and all the errors were syntax errors. I was misspelling most of the keywords. But I'm still having the problem with words not being highlighted and there is this other problem where let's say I type M to start typing Mathf that word doesn't show up on the completion drop down list and therefore doesn't get highlighted. Sorry again for not showing the errors before.

 

I tried to download the assets even from the website but still no luck

 

Hello Dustin,

I have had the same problem, and I solved it
Maybe I can help you.
You said you have not "Accept" button and I thought too BUT I resized my window and the "Accept" button was at the end of window

See you

PS: sorry for my bad english, I'm french^^

 

WOW
OK
That's the end of that problem. Thank you so much
Now I can actually do the tutorial

 

Hey there! I'm having a slight problem with the player - he isn't there. I'm running the most updated version of Unity.

I've noticed that when previewing his animations, he appears in the scene view, but not the game view. This becomes important around step 11 when the playable game should be view able. What I end up with is a player visible on the scene, in proper position, but not in the game itself - though everything else is.

I've experimented and noticed that the invisible player is able to move once, and potentially destroy a wall near that second spot.. but after that he can't move and is still quite invisible. For what it's worth, I've replaced the 'loadlevel' with the more recent 'loadscene' without any hiccups.

I've noticed that the player tile doesn't seem to be called anywhere.. could that be the problem?

 

Hello! Between video 4/5 if you use the "namespace" tag included in the sample scripts, Unity will tell you that the tag already exists in one of the two scripts and it will cause an error.

 

Thanks for the tutorial! I'm following it now and am almost at the end. Just finished the sound video and wanted to try and make a build. The game is working fine in the editor, but when I build it it skips level 1 and 3. You end up in level 4 with 0 food. I've tried to build the completed version and this has the same issue. I built it both in the Mac version as well as in webPlayer version and they had the same issue.

I've also tried a developer build, but don't really know how to use that, yet. I hope someone can help me with this issue. It's really weird because in the editor it works just fine.

 

I have a error, somebody can help me? I´m in part 5

help plzzz...

 

Hi I've been following this tutorial for a while now I'm currently on 3.06. and throughout the process I've only had the player show up in the game tab when i try to have it play. The rest of the screen was blue. I was wondering if there could be anything specific wrong with it. I mean all of the animations for the player work, but only the player shows there's no floor or walls.

 

Ill have a work through the tutorial again tomorrow morning, as its been a while since ive done it, and help out where I can until Matt gets back.

 

I tried doing this tutorial 4 times exactly as in the videos but for some unknown reason i get many errors with the script and with some other stuff!Later I might post some images about the problem I have.

 

I tried to redownload the project files and import them to a new project I had the same problem!
Maybe is it because the files weren't downloaded correctly ? because when i try to download the project files the download stays at XX% forever!


All these happens when I import the downloaded project! (The first time i didn't had this problem,but now it always there)

Help Please!!!

 

Might be worth a shot, deleting the downloaded package (bin icon) and then trying to redownload again from the start.
Also, just check that your logged into the asset store just in case, maybe log out and back in.
cant think of anything else at the moment that might help.

might be getting import errors due to partial or corrupted downloads possibly, or a runtime error behind the scenes.
What version of Windows do you have out of curiosity?

 

Within your Game Manager prefab, check the BoardManager component.
Do you have all the arrays for walls and floors populated?

when you play the game, do you get the board showing in the scene heirarchy, and is there anything childed to it, as in any wall/food/floor tiles?

 

Hi,

Looks like it cannot find the BoardManager Class.

Can i ask, are you using the BoardManager script that was in the completed folder?

Its just that this is within a different namespace so that it doesn't throw errors when you are working through the tutorial.

in your board manager that you are using to work through the tutorial, do you have this at the top?

Code (CSharp):

1. namespace Completed
2. {

if so, just comment out that line, and remember to comment out the corresponding closing ' }' at the very bottom of the script.

see how you get on, if thats not it, can you post your BoardManager script please, just for a look.

 

Hi,

I wrote a little post in another thread, might get some info from there that might help.
http://forum.unity3d.com/threads/space-shooter-tutorial-q-a.313899/page-26#post-2475431

 

Have a look at your BoardManager script.
check that the spelling and case for your SetupScene function is correct.

if thats not it, can you post your BoardManager script please (using code tags please to make it easier to read)

 

Think it may be related to a bug that was found, and has been logged. see the following post from Matt, and a workaround in its following post.
http://forum.unity3d.com/threads/2d-roguelike-q-a.297180/page-12#post-2448963

hope that helps in the meantime.

 

is the player set to use the correct layer?
when you run the game, does the player show in the scene heirarchy?

 

My PC runs Windows 10 Pro 32-Bit Version!
Also where is the location were the downloaded files are?

 

From what ive read over on Answers, there was a post relating to where they are stored here
http://answers.unity3d.com/questions/45050/where-unity-store-saves-the-packages.html

Fingers crossed Matt will get back to you with a better idea than mine.

 

I tried it but nothing!Is this a bug with unity?

 

Not sure bud, but while we wait for the guys when they get time, know theyre busy with Unite, but I'll have another dig around tomorrow to see what I can find out to get you back on track.

Either that or I've just restarted this tute to refresh memory, so i can pop my bare bones project online to try and at least get you going in the mean time, if we have to go down that route in the interim.

 

Even with the complete project you sent me yesterday does not even work like the others!


I get this errors when i try to open the project you sent me!!

 

ah, thats cos i deleted the Library and temp folders pre upload to save hosting space.

if you click continue, as it looks like you have it should recreate these folders I believe.
the Yellow triangles you are getting, are warnings, more a consideration as opposed to a show stopper error.

doesnt look like you are getting the audio import errors tho, so it may have been a corruption somewhere along the line.

Have a try and loading up the Scene in the completed folder and playing, see if it works.

 

Sorry I forgot to sent the 3rd image where the errors where!As you can see there are 17 of them!I can paly at all the game but either way the warnings about the script where it says to use SceneManager.LoadScene instead of UnityEngine.Application.LoadLevel ,does it cause any problems?
http://forum.unity3d.com/threads/unityengine-application-loadlevel-int-is-obsolete.372915/

 

Sorry man, dont know what else to think about, hopefully a better and workable solution will come to you soon to get you back on track from the guys.

 

Hi guys,

Evening,

If you can please, can you say what video / step in the tutorial you are currently working through.

I see you are using the scripts that were in the Completed folder. are you using all of the scripts or are you typing some in as well?

Just wondering, the 'Wall' reference that its looking for as its looking for a type which in this case is a script and class we have called Wall.cs . do you have a Wall.cs script created? depending what lesson you are on.
If you have the script, can you see if the class name at the top of it matches the filename of the script, and that they are both Capitalised 'Wall'.

Also, something else to bear in mind, you have this script within the Completed namespace (top of the script). this was put in I believe to separate the completed scripts, and the scripts that you will be working through so they wouldnt conflict in the editor as they would be in two different namespaces.

 

Is there a way I can use the chop animation to actually hit the enemy? If yes how can I incorporate it on my script

 

This is a great tutorial, as far as I've gotten!

One bit of feedback, though, for future tutorials: Although you do provide completed versions of the scripts, some people might prefer to slow things down a bit (you go through the code quite quickly, which is great for some people, but not for everybody!) and type it all themselves to get a thorough understanding of what you're doing... which is fine, except that when we pause the video, often the code that you just created is way at the bottom of the video window, and therefore is covered up by the video player's controls while it is paused! Ideally, the current code work area would be in the middle of the screen so we can ponder it while the video is paused, rather than having to go hunt through the completed code files to actually see the code, or progress the video to later on so we can see some line we wanted to look at more closely.

 

as a side note, remember that most of the videos have the completed scripts below the video on the page.
If your watching on the Unity learn / tutorial site that is, as opposed to youtube.

 

Hi, I've completed the tutorial and followed it down to the T and the floaty bits above the I's. The problem I've got is that when I run/test the game, none of the walls are actually blocking my movement? They block the enemy movement, but I can still walk wherever I want within the design space (outside the walls included).

Also, any idea what the default attack keybind is? There's no mention of it at all in the tutorial so I've no idea how to test the attack animation on the wall/zombies.

 

Have any of you experimented with modifications of the "Day" screens between levels? For the project I'm working on, I'm using the Roguelike template because I love the random level generation. But I need specific text in between every level, and it has to be different with each level. How might I achieve this? Thanks in advance!

 

I've been having this same problem as well.

EDIT: As an additional F.Y.I this causes no console errors of any kind for me.

EDIT 2: On a whim i commented out check if game over in the player script under attempt move. This allowed me to move without dying instantly, which was great. However, the first time the player gets attacked by an enemy it still caused instant game over which confused me even further. Upon commenting out the hitPlayer.LoseFood , the monsters still play hit anim and sfx but no longer kills or deals damage to the player. Although the player still plays hit noise and anim. Then if i undo that and just comment out CheckIfGameOver(); under LoseFood in the player script the damage is done normally from the monsters and walking but no death is incurred at <=0. I get the feeling that the answer to this is just staring at me right in the face and I can't pick up on it.


EDIT 3: Upon Debugging, anything that had to do with food subtraction is being subtracted normally. However, if the lines of script that check if game over aren't commented out , anything that has a CheckIfGameOver is just calling gameover (one step still subtracts 1 food in the console when debugged but causes game over, same with the enemies damage, get hit lose 10,20 food still have leftover food points , die anyway)




At the end of the adding music and sound effects tutorial when the video asks you to play test, it simply causes game over on first move. The thing that is most frustrating is that before adding the audio the game ran flawlessly. Ive been through this entire thread and the only help I've been able to dredge is that somehow the players food is getting set to zero on first move. Ive fiddled around with several things in the scripts. the game manager in the inspector is correctly set to 100 as is the script referencing it. I even, at one point (in an act of desperation) set the food game over requirements to if (food >= 0) and then set the players starting food to -1 to see if something was being subtracted, or just set to zero. This still resulted in game over on first move. However this made it very clear that something somewhere is setting the players food points to zero on move. This of course leads me to believe there is something up with the AttemptMove function. However the only thing added to this before it stopped working properly that seems like a suspect is

Code (CSharp):

1. RaycastHit2D hit;
2.         if (Move (xDir, yDir, out hit))
3.         {
4.             SoundManager.instance.RandomizeSfx(moveSound1, moveSound2);
