Witam, mam skrypt na cobblex chcialbym zrobic tak ze jesli gracz ma pelny ekwipunek to wypada na ziemie ale jesli moze to dodaje mu do ekwipunku niestety cos nie dziala prosze o pomoc ;/

on place mossy cobblestone:
	if tool is {@item}:
		remove 1 of player's tool from player's tool
		cancel event
		wait a tick
		chance of 50%:
			drop 1 diamond helmet of unbreaking 2 and protection 2 and thorns 1 named "22" at block
			stop
		chance of 50%:
			drop 1 diamond chestplate of unbreaking 2 and protection 2 and thorns 1 named "11" at block
			stop
		chance of 50%:
			drop 1 diamond boots of unbreaking 2 and protection 2 and thorns 1 named "33" at block
			stop
