I have the projectile spawning, all fine. Well, except that sometimes (most) the tank is “punted” away from the spawned projectile.
I have not updated the project at all (unreal versions), since I started on 4.15 and haven’t had to change. I tried disabling collision detection on the turret & barrel mesh(es), but that didn’t make any difference (I was thinking perhaps there was an intersection between the sphere and barrel).
btw: I disabled by turning off collisions on the mesh (under LOD0), and setting Collision Preset to NoCollision.
I could move the projectile away from the barrel I guess - but is there a better way?
