Controls are in the project "make new" button is interesting. try it If you are using turbowarp create 20x20x20 worlds or bigger. Default is 10x10x10 because on scratch lists can't have more than 200000 elements This project has: - adjacent squares merging in efficient way - binary space partitioning (it uses bruteforce method to find the most optimal division planes and bsp is only recalculated when something changes) - portal based occlusion culling (it can efficiently determine what polygons are visible and draws only them. Press R to see how it works) This project isn't a simple grid traversal algorithm. It can handle large rooms without lag since it (mostly) doesn't need to process empty space.
