Question

I have a TileMap with my TileSet imported, and am wanting to set up an interaction system. I have already made the interaction system with separate objects that are not in the TileSet, but I am struggling on how to get my interaction system working with the individual tiles in my TileSet, as I can’t seem to find a way to call them in code or send signals to them.

your individual tiles in your TileSet are Cell in the document, you should look into everything that has Cell in it
you can interact with them with coordinate
