G’Day all,
Almost had a heart attack when the lecturer told us to basically spawn a projectile. How the hell do I do that …with just that discussion of UCLASS, then, he gave us a little more information that made me feel more comfortable about it, plus a quick recap of the information before that and was able to do it. Sure enough the projectiles were spawning all around the tank and with the correct rotation 
.
Then I tried to move the tank and shock horror nothing - oh no, what the hell have I done wrong 
. Then I realised the tank was colliding with the meshes of the projectiles blocking movement - what a relief 
.
