what does this mean?

It needs to be like this:

PHP Code: (Select All)

void OnStart()
{
    AddUseItemCallback("", "Key_3", "castle_1", "UsedKeyOnDoor", true);
}

void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
    SetSwingDoorLocked("castle_1", false);
    PlaySoundAtEntity("", "unlock_door", "castle_1", 0, false);
    RemoveItem("Key_3");
}

void OnEnter()
{

}

void OnLeave()
{

}
