Lua Can use with pz and without

[Hbraveq]

Hello guys, I have simple script and I want to edit it, to protect it from using with pz. (Make it usable only ouf of fight)

function onUse(player, item, fromPosition, itemEx, toPosition, isHotkey)

if table.contains({SKULL_NONE, SKULL_WHITE, SKULL_RED}, player:getSkull()) then
player:setSkull(SKULL_NONE)
player:setSkullTime(0)
player:getPosition():sendMagicEffect(CONST_ME_MAGIC_GREEN)
player:sendTextMessage(MESSAGE_EVENT_ADVANCE, "Your frags has been removed!")
db.query("UPDATE player_deaths SET unjustified = 0 WHERE unjustified = 1 AND killed_by = " .. db.escapeString(player:getName()))
item:remove(1)
end

return true
end
