jak napisać railgun do skryptu Quake

Aha chyba to:

on rightclick with stick:

    shot snowball

Nie to to umiem grałaś/eś wogle w quake 3 arena original

chodzi mi głównie o particle ten laser z działa

zrobiłem coś takiego

on right click using 419:
    if player has 1 370:
        if {rail::pal} is true:
            execute command "/playsound tile.piston.out %name of player% ~0 ~0 ~0 10 0.01"
            shoot a egg from player with speed 1000
            damage targeted entity by 40 hearts
            remove 1 370 from player
            set {rail::pal} to false
            set name of the player's tool to "&6[ &b%number of 370 in the player's inventory% &6]"
            wait 2 seconds
            set {rail::pal} to true
        else:
            send "&6Quake &f> &1&lPrzeladowanie!"
    else:
        send "&6Quake &f> &4&lNie masz amunicji!"
