I’ve set up the projectile just like it is in the sample fps project but in my own project the projectile does not collide with anything and just goes straight through. I have no idea if it’s a coding error or something else.
Underneath where it says 'WorldDynamic", your Object Responses are all set to Overlap. They should be set to Block.
To the right of the blueprint in the collision tab change the Collision Presets To BlockAll
