Alright I almost have it like I need it. Maybe you know why it does this last little thing.
Its not exactly going with the crosshair but I think i'll disable the crosshair for this weapon. At least now it the laser moves up and down and stuff.
As you watch the video watch how it kinda sticks to a spot before moving to another spot. Not sure whats causing that.
How i fixed the aiming issue is I clicked Use Look Source to On. and checked parent to origin on the beam effect.
