how to have Armor procedure damage item in players inventory

You need to create a procedure, to create a procedure that gets triggered when you wear your custom chestplate, do this:

Make a procedure like this:

I haven't tested it, but supposedly it should should damage all swords/pickaxes/axes/shovels and hoes when the chestplate is damaged and repair the chestplate, it checks for every inventory slot, including second hand slot, but excluding 2x2 crafting slots and the armor slots themselves. (Creating this procedure was pretty fun though)
If you don't want to recreate it like in the image(which I can understand), you can just import it by pressing "import procedure":

Here's the procedure file that you need to import this way:

(I posted the procedure file on google drive so you can download it and that's the link)

Hope this helps! :)

Does it work though?
