Arrows to move
Some notes for when I use this. Please correct in the comments if I made any mistakes here: ------------------------------------------------------------------------- It got exponentially laggier as I increased the resolution. Here (21x21) is where it can complete it in a screen refresh I can't erode 20% instead of 2 10% frames for the same result. It won't reach 2 pixels out if I do 20%. Making quick generation difficult. Compare to adjacent tiles before eroding. Higher difference between the height of it's neighbors makes it distribute more to that neighbor. DON'T UPDATE HEIGHT AFTER DISTRIBUTING TO AN ADJACENT TILE UNTIL ALL ARE DONE UNLESS THE ORDER IS REALISTIC, OR IT WILL DEPEND ON THE ORDER. (this is a planned feature that isn't added yet) Simulating without rendering could help performance when used in a project.
