Pickaxe Experience Skript

on mine:
    if player's tool is a pickaxe:
        set {_lore} to lore of player's tool
        set {_split::*} to {_lore} split at " "
        set {_exp} to {_split::2} parsed as number
        set {_exp} to {_exp} + 1
        set lore of player's tool to "&e&lEXP: &f%{_exp}% &7/1000"
