Combine Two RuleTiles

I'm trying to combine two RuleTiles in such a way that the tiles will act the exact same when touching a tile from either RuleTile. Picture of what I want it to do.

The left is the way I want it all connected but the darker tiles connecting to the lighter tiles the same way.

I thought an Override Rule Tile would work but it does the exact same thing.

 

Here's what I did to accomplish that: https://forum.unity.com/threads/rule-tiles-with-separate-sprites.972564/#post-6326187

Basically, I modified the RuleTile to supply an array of "friendsTiles." Then I modified the place where "self" vs. "non-self" decision is made to consider friendTiles the same as "self." An alternative approach, also mentioned in that thread, is to write your own custom tile.

 

I tried implementing what you have there and it makes my RuleTile always place the default sprite almost all the time.

Code (CSharp):

1.     public TileBase[] friendTiles;
2.  
3.                 public class TileNeighbor
4.             {
5.                 public const int This = 1;
6.  
7.                 public const int ThisOrFriend = 2;
8.  
9.                 public const int NotThis = 3;
10.             }
11.  
12.   public override bool RuleMatch(int neighbor, TileBase tile)
13.         {
14.             switch (neighbor)
15.             {
16.                 case TileNeighbor.This: return tile == this;
17.                 case TileNeighbor.ThisOrFriend: return tile == this
18.                          || HasFriendTile(tile);
19.                 case TileNeighbor.NotThis: return tile != this;
20.             }
21.             return true;
22.         }
23.         bool HasFriendTile(TileBase tile)
24.         {
25.             if (tile == null)
26.                 return false;
27.             for (int i = 0; i < friendTiles.Length; i++)
28.             {
29.                 if (friendTiles[i] == tile)
30.                     return true;
31.             }
32.             return false;
33.         }

 

What does your RuleTile look like? If the Rule is set up right and the friendTiles are set up right, you might want to step through with the debugger b/c my RuleTile is very customized so there's a chance that Unity and I diverge significantly.

 

I believe this is what the custom rule tile script is for.
