I have been looking around on the Internet but haven't found anything.
So here is my question:
This is the map of an old game, Airborne Assault.
I would like to write a prototype with a map in this style (gridless, 2d top down) and a unit i can move around,
but I don't know how to get started. For example what datastructure do I need for the map?
If someone could link a tutorial or give me some advice that would be really helpful.
