I am new user to Construct 2. I'm having trouble understanding what tilemaps are supposed to accomplish. My understanding of a tile map is that in a 2D game there is a graphics layer and a tile layer. The tile layer controls movement, can hold events, etc. However, this does not seem to be what a tile map does in Construct 2. I read through the manual entries but I still cannot wrap my head about what its purpose is.
In plain English, what is a tile map supposed to do?
