Je ne vois pas ce que le player vient faire là dedans surtout

public void onUpdate(ItemStack stack, World world, Entity entity, int i, boolean b) { if(!stack.hasTagCompound()) { stack.setTagCompound(new NBTTagCompound()); } if(stack.getTagCompound().getInteger("coolDown") > 0) { stack.getTagCompound().setInteger("coolDown", stack.getTagCompound().getInteger("coolDown") - 1); } }ça fonctionnera mieux comme ça.

Ah oui, merci robin.
Je tâcherai de retenir ce genre d’erreur…
