Voici le même code que @rois2coeurs, mais un poil plus opti, avec + de messages, et surtout, sans le wait 1 tick (sinon il auraient pu cliquer 2 fois dessus par exemple)
on right click with a stick:
if name of tool of player is "&c&lSceptre de heal &7(3)":
heal the player
set name of tool of player to "&c&lSceptre de heal &7(2)"
else if name of tool of player is "&c&lSceptre de heal &7(2)":
heal the player
set name of tool of player to "&c&lSceptre de heal &7(1)"
else if name of tool of player is "&c&lSceptre de heal &7(1)":
heal the player
remove 1 stick named "&c&lSceptre de heal &7(1)" from the player
command /healstick:
permission: healstick
permission message: &cTu ne peux pas faire cela !
trigger:
give a stick named "&c&lSceptre de heal &7(3)" to the player
message "&aTu as recu un sceptre !"
