	permission: whitelist.use
	trigger:
		if arg 1 is not set:
			send "{@servername} &8| &cUse /whitelist add/remove/on/off/list (player)"
			stop
		if arg 1 is "add":
			if arg 2 is not set:
				send "{@Servername} &8| &cYou need to fill in a player."
				stop
			if arg 2 is set:
				add arg 2 to {whitelist::*}
				set {whitelisted.%arg 2%} to true
				send "{@Servername} &8| &cYou've added %arg 2% to the whitelist."
				stop
		if arg 1 is "remove":
			if arg 2 is not set:
				send "{@Servername} &8| &cYou need to fill in a player."
				stop
			if arg 2 is set:
				remove arg 2 from {whitelist::*}
				set {whitelisted.%arg 2%} to false
				send "{@Servername} &8| &cYou've removed %arg 2% from the whitelist."
				stop
		if arg 1 is "list":
			send "{@Servername} &8| &cPlayers added to the whitelist: &r&7%{whitelist::*}%"
			stop
		if arg 1 is "on":
			set {whitelist.stat} to true
			send "{@Servername} &8| &cThe whitelist is now on."
			stop
		if arg 1 is "off":
			set {whitelist.stat} to false
			send "{@Servername} &8| &cThe whitelist is now off."
			stop
		if arg 1 is "setmessage":
			if arg 2 is not set:
				send "{@Servername} &8| &cYou need to fill in the kick message."
				stop
			if arg 2 is set:
				set {km1s.s} to true
				send "{@Servername} &8| &cThe kick message has been changed to: %arg 2%"
				set {kickm1} to "%arg 2%"
				stop

on join:
	if {whitelist.stat} is true:
		if {whitelisted.%player%} is true:
			stop
		else:
			if {km1s.s} is true:
				wait 15 ticks
				kick player due to "%{kickm1}%"
				stop
			else:
				wait 15 ticks
				kick player due to "{@Servername} &8| &cYou're not whitelisted!"
				stop
