A moving projectile with a Capsule should be generating Overlap Events when colliding with a wall, but that isn’t happening. I tried debugging using both C++ and blueprints, there should be a print string or a console message when the collision happens. I can’t figure this out, the Capsule’s settings and the wall’s settings allow for generating overlap events, the collision preset for the Capsule is Query Only and it allows overlap with PshysicsBody (which is the preset for the wall object). I don’t know what I’m missing.
I’m very new to UE5, so I probably won’t be much help. But I think you may need to give more detailed information on your problem, if you want help. Do you have an event graph for your projectile blueprint (and/or wall blueprint) that you can post an image of? Or can you at least describe the nodes you have flowing from the OnComponentBeginOverlap event node in your projectile event graph?
