Do you mean when someone holds rightmb with a normal bow (hunting bow to compound bow I think) and lets go that an arrow will follow a high arc that lands on where the cursor was, but splits into multiple arrows on impact?
Have you tried looking at the projectilecount and editing that? Try playing with a shotgun-class .activeitem -- those can shoot multiple projectiles in one burst because it has the detail "projectilecount: x" in its .activeitem file.
Can I cut in with a related question? I know you can make guns fire more than one of the same projectile, but is it possible to have more than one distinct projectile be fired by the same gun? I ask because I'm trying to make a Slag Launcher that fires a constant stream of molten slag (trash metal slurry) with flamethrower physics, but also randomly shoots out additional sharp bits of unmelted metal and scrap with different physics than the main stream. So that would be about 4 projectiles including the main stream and maybe a couple variations on junk that gets blown out with it, like an iron ball with very heavy physics but higher damage, a metal chunk that goes medium distance, and a sharp piece of shrapnel that flies a long way and pierces. Is this possible within the current limitations of the system? I can't think of any guns that do this offhand, apart from the adaptable crossbow but that's tied into the alt ability.
changing "projectileType" : "<placeholder>", to "projectileType" : [ "<projectile1name>", "<projectile2name>" ], will choose one of the projectiles from the two each shot. I don't know how to do the spoiler code thing yet, sorry.
