Replacing multiple weapons in same slot.

[yuyu3]

Hello, i am getting crazy in replacing weapons, i need to use some tommyguns as upgrades of each other, and those will be given only if the amount of weapon parts are matched.. Concretelly.

-The first tommy gun must replace the chaingun, nothing else is needed with it.
-The second tommygun(double barrel upgrade) must replace the first tommygun and must spawn only if you have 1 weapon part.
-The third tommygun (triple barreled upgrade) must replace the second tommygun and must spawn oly if you have 2 weapon parts..

Ok so there is what i have,..

In the Spawn state of the weapon, put a JumpIfInventory that checks for the player having an item that is given when you upgrade. This JumpIf jumps to a state that spawns the upgraded form, then stops, so that the original weapon is removed.
