sklep na monety

variables:
	{cons::%player%} = 10
on command /sklep:
	trigger:
		open chest with 1 rows named "&1Sklep"
		wait 4 ticks
		format slot 1 of player with 1 stone named "&7Kup kamień" with lore "&7Cena: 1 Coin" to close then run "kupkamien %player%"
on command /kupkamien <player>:
  	trigger:
  		if {coins::%player-arg%} is bigger than 1:
  			add -1 to {cons::%player-arg%} 
  			give 1 stone to player-arg
  		else:
  			send "&cNie masz na tyle Coinsów" to player-arg

Masz szablon, resztę sobie dopisz wg własnego uznania 

A co do pozostałych pkt użyj po prostu send "&7Pozostałe Coiny: %{coins::%player-arg%}%" to player-arg
