I didn't make it!
Dear Reader. If Someone Knows How To Make A Gun Shoot A Vehicle, Please Inform Me. I Know How To Make It Shoot It... But It Always Crushes Me.. Anyone Know How To Change The Gun So It Shoots It And Stops Infront Of Me? Thanks, Simon.:)
Yes, I know. But you need to do this in a Campaign map. Copy the vehicle's meta number, then paste it in place of the projectile(suppose pistol's projectile)'s meta. Then look above it all ,under the title bar. You'll see something like [proj]v [objc]v [none]v or something like that in a option box. Change the proj value to vehi. Then go play Halo and shoot the pistol(if you've modded a pistol projectile). The vehicle will appear. But it may send you underground. So while you shoot, jump up and you wont fall. But your sheilds may(or may not) get drained. Hope that helped you.
Also, try editing the projectile velocity. That will keep it from falling straight down.
