How to make Custom Rule Tiles in Unity Video

Usage

  • Custom Attributes:
public class MyTile : RuleTile {
	public string tileId;
	public bool isWater;
}
  • Custom Rules:
public class MyTile : RuleTile<MyTile.Neighbor> {
	public class Neighbor {
		public const int MyRule1 = 0;
		public const int MyRule2 = 1;
	}
	public override bool RuleMatch(int neighbor, TileBase tile) {
		switch (neighbor) {
			case Neighbor.MyRule1: return false;
			case Neighbor.MyRule2: return true;
		}
		return true;
	}
}
  • Expansion Rules
public class MyTile : RuleTile<MyTile.Neighbor> {
	public class Neighbor : RuleTile.TilingRule.Neighbor {
		// 0, 1, 2 is using in RuleTile.TilingRule.Neighbor
		public const int MyRule1 = 3;
		public const int MyRule2 = 4;
	}
	public override bool RuleMatch(int neighbor, TileBase tile) {
		switch (neighbor) {
			case Neighbor.MyRule1: return false;
			case Neighbor.MyRule2: return true;
		}
		return base.RuleMatch(neighbor, tile);
	}
}
  • Siblings Tile 1
public class MyTile : RuleTile<MyTile.Neighbor> {
	public List<TileBase> sibings = new List<TileBase>();
	public class Neighbor : RuleTile.TilingRule.Neighbor {
		public const int Sibing = 3;
	}
	public override bool RuleMatch(int neighbor, TileBase tile) {
		switch (neighbor) {
			case Neighbor.Sibing: return sibings.Contains(tile);
		}
		return base.RuleMatch(neighbor, tile);
	}
}
  • Siblings Tile 2
public class MyTile : RuleTile<MyTile.Neighbor> {
	public int siblingGroup;
	public class Neighbor : RuleTile.TilingRule.Neighbor {
		public const int Sibing = 3;
	}
	public override bool RuleMatch(int neighbor, TileBase tile) {
		MyTile myTile = tile as MyTile;
		switch (neighbor) {
			case Neighbor.Sibing: return myTile && myTile.siblingGroup == siblingGroup;
		}
		return base.RuleMatch(neighbor, tile);
	}
}
