I have a projectile ball, a simple sphere at a scale of 0.05 (so it’s 5x5x5 units in size), this is it’s collision profile:
And then I have a skeletal mesh, this is it’s collision profile:
And this is what happens:
So the collisions are working, but the hit event is not called, what’s happening?
Thing is, the hit event IS generated if I say take a third person bp character and run into this character.
So I am very confused about what is going on.
Not sure, but that bouncing mechanic might be what’s preventing the projectile to trigger a collision. Can you disable that feature and try it that way?
There isn’t any special bouncing mechanic, it’s just a sphere with a projectile movement component on basically default settings with speed and gravity scale being the only ones i changed.
The bounce is just a result of physics simulation…
Wait a second, ok so i disabled physics for the projectile mesh and now i get the collision message.
But I want physics, why is it like this?
Can you try using the “On Component Begin Overlap” node instead of the ones you’re using currently
Overlap events do seem to work a lot better, however they also very often do not trigger, and similarly disabling physics simulation seems to fix that unreliable triggering of them 
.
I’m glad you got it working! I guess it’s because the engine prioritizing events. It’s how engine handles things
