need a gun trigger 4 campaign!

I am making a Resident Evil campaign (look at sig.) and need a trigger to run outta 1 ammo every shot. can n e 1 help me??

I got a old version up in my sig. Though I am going to enter an uptated one where you can have multiple weapons in a contest.

I've got one of my own, based on Grater's Orb Ammo System; want me to PM you the details? (I've further modified it, since I'm making a modern war map that uses essentially the same combat system as Resident Evil.)

Check here (if you dont already have it)

You will need to copy it and change certain things for each player

VARIABLES NEEDED
PlayerAmmo(Integer Array)(X)
x=number of players

TRIGGER 1

EVENTS:A units is attacked

CONDITIONS:Player Ammo[1] is greater then 0
Owner of(Attacking Unit) Equal to Player 1 Red

ACTIONS: Set Player Ammo[1]=Player Ammo[1]-1
Run (TRIGGER 2) ignoring conditions
-----------------------------------------------
TRIGGER 2

EVENTS:(None)

CONDITIONS:(None)

ACTIONS: Set Player 1 current lumber to PlayerAmmo[1]-0
-----------------------------------------------------------
TRIGGER 3

EVENTS: A unit is attacked

CONDITIONS: PlayerAmmo[1]=0
Owner of attacking unit=Player1 Red

ACTIONS: Unit-Order Attacking Units to Stop
Game-Display text for Player Group- Player 1 Red "You have no ammo"
------------------------------------------------------------
your lumber is your ammo

all you will need to do is make a trigger so when you pick up ammo it adds x to PlayerAmmo where x is how much ammo you picked up.

while you can have more then 1 gun under this it uses 1 ammo type for all
