Hi all,

I’m trying to kill an enemy and make it a ragdoll. How can I remove the Ai controller and stop any behavior?  
I’m using a behavior tree.

Hey! You can use the function: Detach From Controller Pending Destroy  
This will detach the controller from the AI. You can refer to the picture given below:-

“Detach From Controller Pending Destroy” Node working perfectly to me also. Destroy all (spawned)AIControllers (eg.: 100), then i can spawn another 1.
