Hi,
I’m trying to implement a system that can detect hits on certain parts of a mesh and apply different damage.
I have created a USceneComponent that is derived from UCapsuleComponent and am trying to bind the OnComponentHit from the parent so I can fire off my own event after some damage processing.
It seems that I’m not getting the OnComponentHit event to trigger in my Damage Modifier class. Any thoughts as to why? Or if there’s a better approach I’m all ears
