  • Proper Undo/Redo (@nickgirardo)
  • Export/Import to ScriptableObject

• Access the tilemap through a clean API

   //Get tiles by using
   GetTileAt(Vector2 worldPosition);
   GetTileAt(int x, int y);
   //Set tiles by using
   SetTileAt(int x, int y, ScriptableTile to);
   //Invoke a callback to update tiles
   UpdateTileAt(int x, int y);
   UpdateTiles();
   UpdateNeighbours(int x, int y);
   UpdateType(ScriptableTile type);
   [... and more]

How do I make my own tiles?

In the project window click on Create > Tilemap > Tiles and select a scriptable tile type to create. You can edit the tiles variables by just clicking on it, like anyother asset.

If you want to create your own scriptable tiles (Like the RandomTile or AutoTile) then click on Create > Tilemap > Create C# Tile Script and edit like anyother script. Alternatively create a C# class that inherits ScriptableTile

Can I make custom tools?

Yes. If you want to create your own tools (Like the Pencil or Eyedropper) then click on Create > Tilemap > Create C# Tool Script and edit like anyother script. Since all tools (even the included ones) inherit from ScriptableTool you can also simply create a C# class that inherits from ScriptableTool. Any class that inherits ScriptableTool will automatically be able to use in the Edit Mode tile editor, any public variables will also be exposed in the tile editor toolbar.
