It does not have an area where I can select the Component file from the file tree. I do not know if this is a bug, but I want to try this game engine out.
Edit 1: I tried to close and reopen the editor, but that doesn’t seem to work
This is not a bug. A Tile source is not a component you can add to a game object. What you need is a Tile map, but you need to create a Tile source before you can add a Tile map.
