So, I am making a block zombie game (becouse I dont know how to 3D model) and after making the zombie AI it worked. Now, Once I finished the first area I made a buyable door that leads you to the next once you get 750 points.
When I Cross To the 2º area the zombies get stuck on the fences that separate the area. Here is a video that shows what I mean:- YouTube
Thanks in advance
