Yea, I 'm going to go back in and take another look at the forward vector - I moved the gun object into the character blueprint and I’ve got something almost working - you can see when the angle changes up or down the rotation of the gun goes off by a greater value, but when the target is closer to the horizon the aiming is more accurate
It’s still not aiming at the center of the screen, tho
[edit] Also the gun is pointed in the opp direction of the bullets (not sure why)
I ended up using the camera boom’s rotation and not the camera, so it makes more sense now to use the ( forward vector of the gun == forward vector of the camera )? I’ll try that now
