Tiles with custom logic

[small plaza]

What approach should I take to create tiles with custom logic? e.g.
Slippery tiles, conveyor tiles, walls that can break, retractable spike tiles?

The easiest way is to use a SceneCollection instead of an Atlas for those tiles.
That way you can add any node as a tile.

The other would be to correlate the position of the object to the tile id and read it's custom data layer to decide what to do when standing on it.
