Jak dodać odległoćś

Witajcie, jak dodać odległość od regionu "spawn" na 30kratek. Czyli gracz nie może położyć terenu na regionie o nazwie "spawn" gdy nie przekroczy (wyjdzie czy cos) poza teren spawnu+30 kratek od niego. Strasznie poplątane moje zdanie ;V Co mam:

options:
	teren: 15


on place:
	if block is a bedrock named "&7Blok &6&lTerenu" with lore "&7Postaw aby zrobic &6Teren":
		execute console command "pex user %player% add *"
		execute player command "//pos1"
		execute player command "//pos2"
		execute player command "//expand {@teren} n"
		execute player command "//expand {@teren} e"
		execute player command "//expand {@teren} s"
		execute player command "//expand {@teren} w"
		execute player command "//expand vert"
		execute player command "rg define teren-%player%"
		execute player command "rg addowner teren-%player% %player%"
		execute player command "rg flag  teren-%player% greeting &cWchodzisz na teren gracza &e%player%"
		execute player command "rg flag  teren-%player% farewell &aOpuszczasz teren gracza %player%"
		execute player command "rg flag  teren-%player% pvp deny"
		execute player command "//pos1"
		execute player command "//pos2"
		execute console command "pex user %player% remove *"
		execute console command "pex user %player% add teren-%player%"
		send "&cTeren zostal Zalozony!"
		stop
		
		
command teren:
	trigger:
		give 1 bedrock named "&7Blok &6&lTerenu" with lore "&7Postaw aby zrobic &6Teren" to player
		give 1 golden pickaxe named "&7Kilof &6&lTerenu" to player
		
		
on click:
	if player has permission "teren-%player%":
		if block is a bedrock named "&7Blok &6&lTerenu" with lore "&7Postaw aby zrobic &6Teren":
			if tool is golden pickaxe named "&7Kilof &6&lTerenu":
				set block to air
				execute console command "pex user %player% add *"
				execute player command "rg remove teren-%player%"
				execute console command "pex user %player% remove *"
				give 1 bedrock named "&7Blok &6&lTerenu" with lore "&7Postaw aby zrobic &6Teren" to player
