MethodBuilder Internal Error?

Hey everyone.

I have been looking for a while now and I can't find the source of this error.
I checked all the code I wrote and everything seems fine in Visual Studio. It compile with some warnings, like unused variables, but no errors. Then when I load the assembly in unity, I have this error:

It's preventing me from testing anything on my project since it won't launch now

Anyone has an idea what I could do to fix it?

Here is the ChangeScreen method mentionned in the error log if it helps:

Code (CSharp):

1. public void ChangeScreen( ScreenType screenId )
2.     {
3.         if (_debug) Debug.Log("[Master] Loading screen " + screenId);
4.  
5.         //Save screen id
6.         currentScreen = screenId;
7.  
8.         //Hide any window open
9.         WindowPrompt_Enter(WindowPromptType.NONE);
10.  
11.         //Reset flags
12.         inLevel = false;
13.         inEditor = false;
14.         inPrompt = ActionPromptType.NONE;
15.         currentTool = EditorTool.NONE;
16.  
17.         //Do specific actions for screens
18.         switch (screenId)
19.         {
20.             //Loading Screen
21.             case ScreenType.LOADING:
22.                 ui.LoadScreen(screenId);
23.                 break;
24.  
25.             //Main Menu Screen
26.             case ScreenType.MAINMENU:
27.                 ui.LoadScreen(screenId);
28.                 break;
29.  
30.             //Editor welcome screen
31.             case ScreenType.EDITOR_SPLASH:
32.  
33.                 inEditor = true;
34.                 inLevel = false;
35.  
36.                 //Load UI
37.                 ui.LoadScreen(screenId);
38.  
39.                 //hide tool menu tool
40.                 Editor_Tools_Enter(EditorTool.OFF);
41.  
42.                 break;
43.  
44.             //Editor in map screen
45.             case ScreenType.EDITOR_INMAP:
46.  
47.                 inEditor = true;
48.                 inLevel = true;
49.

51.                 ui.LoadScreen(ScreenType.EDITOR_INMAP);
52.

54.                 Editor_Tools_Enter(EditorTool.NONE);
55.  
56.                 //Select default editor objects
57.                 DataUnit defaultUnit = data.units[0] as DataUnit;
58.  
59.                 if (defaultUnit != null)
60.                     Editor_UnitType_Select(defaultUnit);
61.  
62.                 if( mapData.layers.Count > 0 )
63.                 {
64.                     DataMapLayer defaultLayer = mapData.layers[mapData.layers.Count-1] as DataMapLayer;
65.  
66.                     if (defaultUnit != null)
67.                         Editor_Layers_Select(ref defaultLayer);
68.                 }
69.                
70.  
71.                 break;
72.  
73.             //In-game screen
74.             case ScreenType.GAME_INMAP:
75.                 logic.Map_Load(ref mapData, false);
76.                 ui.LoadScreen(ScreenType.GAME_INMAP);
77.  
78.                 break;
79.  
80.             default:
81.  
82.                 break;
83.         }
84.     }

 

I still haven't found the source of the errors, any hint plz?

 

I know this post is old, but I just faced this problem, and solved it removing all the debug.log statements.. (sic)

 

Same as me, just faced this problem.

I've restarted the Editor, restarted Visual Studio, cleaned and rebuilt the assemblies... but the errors persist.

 

I've just managed to fix this. It seems the error was that I've changed a function's parameter type from int to an enum, but did not update all the calls to it that were still using an int. That would generate an implicit cast from int to enum, which seems to be OK by Visual Studio, but not Unity, and because VS is OK with it, it cannot tell you the exact problem.

In code example:

before:

Code (CSharp):

1.  
2. // in CursorManager script:
3. public void ChangeCursor(int cursorTypeIndex) {
4.     currentCursorType = (CursorType)cursorTypeIndex; // works fine
5.     // ... do some other stuff for updating the cursor
6. }
7.  
8. // other script that wants to change the cursor:
9. private void DoSomething() {
10.     // other things to do
11.     cursorManager.ChangeCursor((int)CursorType.PICKUP); // worked fine
12. }
13.  

after:

Code (CSharp):

1.  
2. public void ChangeCursor(CursorType cursorType) {
3.     currentCursorType = cursorType;
4.     // ... do some other stuff for updating the cursor
5. }
6.  
7.  
8. // other script that wants to change the cursor:
9. private void DoSomething() {
10.     // other things to do
11.     cursorManager.ChangeCursor((int)CursorType.PICKUP); // NOT GOOD, implicit cast to CursorType that confuses Unity
12. }
13.
