That example is a simple BP_Ball Actor that inherits from AActor, nothing more. It’s not a pawn or anything like that so it doesn’t carry any overhead that pawns or projectiles do. to handle inter-object collision interactions, i simply created a new Collision Profile in projects settings called “Ball”, and set my BP_Ball to that. You can then specify what sort of actors the ball is allowed to interact with. For my game, balls cannot interact with other balls or power-ups that float around. Hope this helps
