I need help with a progression prevention plugin

I'm trying to make it so if a player has a diamond chestplate in their inventory it gets rid of it and just gives them 8 diamonds but it isn't working no matter what I'm doing

I’ll make a basic script that you can modify to work for your server

I think this will work

I think this will work

That code is okay but looping every item in a player's inventory, especially if you have 20+ online players is not going to be great for performance. A better option would utilize inventory click events. That way, the moment a player clicks the item itself, it refunds the required materials without needing to use any loops whatsoever. I put an example below this explanation. Alternatively, to add more items to refund, you can use list variables and functions.

on inventory click:
    event-inventory is player's inventory
    event-item is diamond chestplate
    remove event-item from player
    give player 8 diamonds

That’s what I was thinking, but I just wanted to give a quick “simple” answer
