Having a collision sphere as the root component causes projectiles to “wrap around” an object and continue on original trajectory. They do not pass through on object but simply follow its contour around the surface until the projectile can resume its original trajectory.
I was able to fire projectiles fine until I added a root Collision Sphere to my actor. I had a few problems with things firing in random vectors. That turned out to be capsule collision with my actor. I changed settings to ignore that and it helped. My Suggest Projectile Projectile Velocity appears to have stop functioning at this point (not the issue I am addressing here though). I added a custom channel so that I could exclude objects of the same time from colliding with themselves (my fireballs spawn a fire when they explode for several seconds and I do not want other fireballs to collide with the fire).
Projectiles began either going through walls or bouncing off them (‘Should Bounce’ is set to false in projectile movement), including the terrain, static and dynamic objects. Included in the pictures are my projectile settings. Although the pictures are of a child, the parent behaves the exact same way.
