I really don't know where to post this topic and I'm sure it's in the wrong place.
It's about projectiles.I made a plasma blaster in my game and made a long green projectile model for it.The problem is that when I shoot,the projectile shows at the crosshair and it's away from the gun.How can I make the projectile to shoot from the gun,not from the crosshair.Will it need a script for that,making the projectile shoot from the weapon's bone?

The manual:

viewlaunchoffset: offset in the X, Y and Z directions from screen center to the projectile launch point (Projectile weapon only)
viewlaunchbone: name of bone in viewactor to launch projectile from (Projectile weapon only)

... ........Maybe it's because of the sun....this month I asked several questions that I have just completely forgot the answer (and the answer is simple) thanks Juutis!
