Can anyone point me to some resource on how to create a game map. I don't mean the design, I mean the functioning, e.g. how to prevent players from going through walls. I'm quite new to this, in case you haven't noticed.

I think what you want is more on the level design side of things, not cartography. Saying cartography make it looks like you need help with terrain creation (ground, hills, rivers, lakes, etc).

Do you have any experience with game development? Are you using a game engine? If yes, which one? Because what you want (prevent the player going through objects) is covered in the basics of many game engine tutorials. For example, in Unity, you can add colliders to objects and the player, so the objects will not go through each other. See the video bellow for an example.

Thanks for your quick reply. I think the best way to put it is “Are the movements of the players constrained by ‘if … else’ statements or there is some sort of map or wall object?”

Thank you very much, Ruti. I will.

@Rutin Ok, thanks again.
