Hopper z wykryciem

Witam, pomoże ktoś hopperem? Nie powinno ciągle spamić tym loopem w else.

variables:
	{_Cooldown} = 3 real seconds


on hopper pickup:
	if event-item is diamond sword:
		set {_location} to "%event-location%"
		if {_location} contains "x: 376, y: 64, z: -767":
			loop all players in radius 3 of event-location:
				if loop-player is in region "dominik":
					metadata "NPC" of loop-player is not set
					send "Checking..." to loop-player
					execute console command "npc create Ojdziec --at 376.5,67,-769.8,world"#Type write: --type Villager before --location to spawn Villager!
					wait 1 tick
					execute console command "npc create Madka --at 374.5,67,-769.8,world"#Type write: --type Villager before --location to spawn Villager!
					wait 1 tick
					execute console command "npc sel Madka"
					wait 1 tick
					execute console command "npc look"
					wait 1 tick
					execute console command "npc sel Ojdziec"
					wait 1 tick
					execute console command "npc look"
					wait 4 real seconds
					strike lightning effect at location (374), (69), (-770) in world "world"
					strike lightning effect at location (376), (69), (-770) in world "world"
					execute console command "npc remove Madka"
					execute console command "npc remove Ojdziec"
					stop
	else:
		cancel event
		if difference between {_Cooldown} and now is smaller than 3 seconds:
			loop all players in radius 5 of event-location:
				metadata "NPC" of loop-player is not set
				send "This is not diamond, dominik will break you" to console
				spawn 2 zombies at loop-player's head
				stop
			set {_Cooldown} to now

Edit: +Powinno wykryć gracza, który tam wrzuca by nie było że itemy same wpadają i triggerują..

+ prosiłbym o cooldown na to wywołanie "if something between now is now:".
