Give random item out of all items to player

 

[Goose]

Using Runakai's bit of code, this is what I made.

every 15 seconds in "world": #change delay between items given
    loop all players:
        if {random.%loop-player%} is true:
            give random item out of all items to loop-player
        else:
            stop
# all this does is have the player start receiving items regardless if they disabled it before leaving or not
on join:
    set {random.%player%} to true
# this is a command that allows the player to toggle receiving items
command toggle:
    trigger:
        if {random.%player%} is true:
            set {random.%player%} to false
            send "&cYou will no longer receive items!"
        else:
            set {random.%player%} to true
            send "&aYou will now receive items!"
