Single-Use weapon

[billyda59]

I'm using RPG Maker XP. In my game, I want to make a particular type of weapon single-use. I need to figure out some way to make it so that when the player attacks an enemy and weapon X is equipped, it will trigger a common event and reduce the players amount of weapon X by 1.

In theory, this idea could also be used for bow and arrows with a slight modification, if someone wanted to make the player have a finite amount of arrows... just saying.

If anyone can figure out a way to make this trigger a common event, or however else this might be doable, I'd appreciate the input. Also, I'd prefer not to use scripting. I know virtually nothing about scripting.
