How do I make AI objects not walk on top of each other?

Question

In this screenshot, you can see that all of the AI objects are happily doing their thing. However... ...in this screenshot, they are on top of each other. This happens when they reach their destination, and for some reason gravity will not work for them, so they can't fall down. What is causing this, and how can I stop it?

Thanks! P.S. I'm using the A* Unity Pathfinding Project for the AI.

Have you tried adjusting the stopping distance of the NavMeshAgent components of the characters?

http://docs.unity3d.com/ScriptReference/NavMeshAgent-stoppingDistance.html

If that's not enough, you could add a script component that uses the onTriggerEnter method that will GetComponent(NavMeshAgent).Stop() when it detects a collision with another navmeshagent gameObject collider.

This seems to work a LITTLE better, but they still climb on top of each other to avoid each other. EDIT: Just realized this doesn't work at all, because I'm not using navmeshes. I'm using the AStar pathfinding project's components.

Hi @dubstaphone,

I have the same issue, did you solve it? I've been trying changing Rigidbody values (Mass, Drag, Angular Drag) but nothing. I hope you can help me somehow.

Thank you!

Unity is very poor in this regard, best to get rid of physics interactions between moving objects altogether and do your own, you can try all things everyone suggests and believe me, nothing will work, you should just use Triggers and Raycasts and put them on layers that don't react to each other on the built in physics

ps if you change Step Offset to 0 that will stop it but then the character won't climb anything!

For me worked to lower the "Slope Limit" stopping the "character Controllers" to climb on each other.

Sometimes you also have to increase the "Capsule Collider".
