i'm trying to create a procedural terrain generator, but im encountering some difficulties regarding collision and camera positioning [the idea is to be isometric].
the main idea is to always keep 9 chunks around the player, I'm searching on the internet, but it's difficult to find something that works, this is the code I got so far:
Code: Select all
