Having AI avoid eachother


I have implemented the A* path finding project pretty well into my Unity game now, but I’m having problems with multiple AI taking the exact same path and ending up directly on top of eachother (The gametype is 2D Topdown). If I were to use ray casts to locate other AI collides, how would I use that with the A* system and how would I tell it how to move according to the Ray hits?


You can use local avoidance to keep them from moving exactly on top of each other.
For something similar to raycasting you might want to check out UnitySteer or similar 3rd party software.
