Spawning a new actor of the same class infinite loop Solved! But i have another problem with collision of pawn

[TJ_V]

By default, the setting for the PhysicsBallBP collision is PhysicsActor. You will need to make sure that the Collision Preset of the PhysicsBallBP and the blueprint Trigger volume will interact.

Try one of these settings:

PhysicsBallBP = PhysicsActor & Trigger = OverlapAllDynamic

or

PhysicsBallBP = Pawn & Trigger = OverlapOnlyPawn
