Sounds like collision issues. Your line trace is hitting your capsule component.
My projectile approach/preferences…
Create an object type for your pawn capsule (capsule component) and one for your projectile collision. https://docs.unrealengine.com/en-US/…ype/index.html
Update the collision for the capsule component. Set projectile interaction to ignore.
Create a BP for your projectile (Actor).
Update the projectiles collision to “projectile”. Set Pawn Capsule interaction to ignore.
This will prevent all projectiles from interacting (colliding) with pawn capsules. The added benefit is now projectiles will interact with the skeletal mesh. You can do per bone hit detection (arm, leg, hand, neck, head etc).
Next add a Hit event in the projectile class (On Component Hit). Let this event determine hits and spawn the Hit FX …emitters, decals, sounds etc. Added bonus is you no longer need delays as in your posted bp. Plus you’ve just increased your multiplayer replication performance and ease of integration.
