[megsb927]

Hi guys well here's the problem: You go into map3, a door in the room is locked, you leave this room to get a key, but when you come back the door is unlocked before you can use a key on it... here's the script for map3:
void OnStart()
{
AddUseItemCallback("", "Key3", "castle_1", "UsedKeyOnDoor", true);
AddUseItemCallback("", "Key4", "castle_2", "UsedKeyOnDoor", true);
}

void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("castle_1", false, false);
PlaySoundAtEntity("", "unlock_door", "castle_1", 0, false);
RemoveItem("Key3");
SetSwingDoorLocked("castle_2", false, false);
PlaySoundAtEntity("", "unlock_door", "castle_2", 0, false);
RemoveItem("Key4");
}
void OnEnter()
{

}

void OnLeave()
{

}
