How to loop all raw items

[DatriX]

Hi, I need help with looping.. I am making minigame Item Rush

My problem is that I dont know how to reset (or set false) all variables where is %raw name of item% (in my code is {ir.%player%.%raw name of item%} )

Here is my code

on pick up:
    send "&7Vzal jsi %raw name of item%!"
    if {ir.%player%.%raw name of item%} is true:
        stop
    else:
        set {ir.%player%.%raw name of item%} to true
        play sound "entity.experience_orb.pickup" with volume 0.5 to the player
        add 1 to {ir.%player%}
        send "&2&lMáš %{ir.%player%}% bodů!!"
        stop

command /irend:
    trigger:
        set {_ir} to true
        loop all raw items:
            loop all players:
                set {ir.%loop-player%.%loop-raw-item%} to false

on pick up:
    send "&7Vzal jsi %event-item%!" to player
    if {ir::%player%.%raw name of item%} is true:
        stop
    else:
        set {ir::%player%.%raw name of item%} to true
        play sound "entity.experience_orb.pickup" with volume 0.5 to the player
        add 1 to {ir::%player%}
        send "&2&lMáš %{ir::%player%}% bodů!!" to player
        stop
 
command /irend:
    trigger:
        set {_ir} to true
        clear {ir::*}

If you use lists instead of variables, you can easily clear them
