Iv got a couple questions. Mainly because i am new with Tiled.
I have made a road, and i need it for my enemies to walk on only and not off into other areas, so how do i do that, some kind of collision?, if so how?.
I would use the polygon tool for this. It allows you to create polygon objects on your map. You can also attach additional context to the areas using the object properties
Note that some libraries are not up to date with tiled latest features. You will need to have a look at wether the libraries supports all the tiled features you decide to use.
