Projectile collision

When I shoot my projectile, how do i make a collision when it hits another actor (the enemy), but it overlaps the character shooting the projectile?

So you want the projectile to overlap your actor, yet collide with everything else but?

@Wxstern Basically like a gun, i want my projectile to hit all other actors (enemies), but it overlaps the actor (character) shooting the projectile. If that makes sense.
