////////////////////////////
// Run first time starting map
void OnStart()
{
AddUseItemCallback("", "awesomekey_1", "mansion_1", "UsedKeyOnDoor", true);
}

void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("mansion_1", false, true);
PlaySoundAtEntity("", "unlock_door", "mansion_1", 0, false);
RemoveItem("awesomekey_1");
}
