Mam taki kod ale nie dziala poprawnie

on script load:
	if folder "plugins/PVPCore" doesn't exists:
		create folder "plugins/PVPCore" 
	if file "plugins/PVPCore/config.yml" doesn't exists:
		create file "plugins/PVPCore/config.yml"
		set "captcha" to "true" in yaml file "plugins/PVPCore/config.yml"
		set {captcha} to single value "captcha" get of "plugins/PVPCore/config.yml"
on chat:
	if {captcha} is true:
		send "ello"
