Trying to Script TileMaps, Saving issues...

Hey guys I hope you can help, I looked everywhere but I can figure out why my tile maps get all fuzzed up when loading a prefab of a tilemap.



As I say.. drag it into the scene from the project window unity starts having a fit and freezes, its about 10 mins until I can finally delete it from the hierarchy.

So here my code thats run on a blank tilemap to spawn a CustomTile class I made that inherits from Tile

Code (CSharp):

1. public void SpawnTiles()
2.     {
3.         if (FloorTile == null)
4.         {
5.             FloorTile = ScriptableObject.CreateInstance<CustomTile>();
6.         }
7.         FloorTile.sprite = FloorSprite;
8.         FloorTile.color = FloorColor;
9.         if (WallTile == null)
10.         {
11.             WallTile = ScriptableObject.CreateInstance<CustomTile>();
12.         }
13.         WallTile.sprite = WallSprite;
14.         WallTile.color = WallColor;
15.         if (tiles.Length != mapSizeX * mapSizeY)
16.             tiles = new CustomTile[mapSizeX * mapSizeY];
17.         if (tilePositions.Length != mapSizeX * mapSizeY)
18.             tilePositions = new Vector3Int[mapSizeX * mapSizeY];
19.         tileMap.ClearAllTiles();
20.         int index = 0;
21.         for (int y = 0; y < cellmap.GetLength(1); y++)
22.         {
23.             for (int x = 0; x < cellmap.GetLength(0); x++)
24.             {
25.                 tilePositions[index] = new Vector3Int(x, y, 0);
26.                 cellCache[x, y] = cellmap[x, y];
27.                 switch (cellmap[x, y])
28.                 {
29.                     case 0://Floor Tile
30.                         tileMap.SetTile(tilePositions[index], FloorTile);
31.                         //tiles[index] = ScriptableObject.CreateInstance<CustomTile>();
32.                         //tiles[index].sprite = FloorSprite;
33.                         //tiles[index].color = FloorColor;
34.                         //tiles[index] = new CustomTile(FloorSprite, FloorColor);
35.                         break;
36.                     case 1://Wall Tile
37.                         tileMap.SetTile(tilePositions[index], WallTile);
38.  
39.                         //tiles[index] = ScriptableObject.CreateInstance<CustomTile>();
40.                         //tiles[index].sprite = WallSprite;
41.                         //tiles[index].color = WallColor;
42.                         //tiles[index] = new CustomTile(WallSprite, WallColor);
43.                         break;
44.                 }
45.                 index++;
46.             }
47.         }
48.         //tileMap.SetTiles(tilePositions, tiles);
49.         Debug.Log("Spawned " + tiles.Length.ToString() + " Tiles");
50.  
51.         tileMap.RefreshAllTiles();
52.     }

oh and heres my custom tile class just incase

Code (CSharp):

1. [System.Serializable]
2. public class CustomTile : Tile
3. {
4.     public CustomTile()
5.     {
6.     }
7.     public CustomTile(Sprite _sprite, Color _color)
8.     {
9.         sprite = _sprite;
10.         color = _color;
11.  
12.     }
13. }

Then i just save it via prefabutility or manually.
everything is fine up until the point I want to load the prefab. Even if i saved the prefab manually via dragging it into the project window it still comes back fuzzy.

Anyone know whats up? I figured it might be because my Tiles are not actual assets just instances. if this is the case does anyone have a work around?

 

Ok I dont know what I changed to get this but i think its progress
Now when i bring back the prefab into the scene unity doesnt freeze but the tilemap still comes out odd.

top grid is what it looks like when i save it
bottom grid is what it looks like when i load the prefab.

 

Ok actually...
everytime i drag the prefab back in it comes out a different shade of pink? whaaaaaaaat the heck lol

 

When there's no material or sprite given, Unity renders the stuff in pink.
