How to input sound?

[fuytko]

It doesn't work

I have this in my .HPS file from map

void PickLetter(string &in asEntity, string &in asType)
{
PlayMusic("Letter_01", false, 0.7f, 0, 10, false);
}
void EntryRoom(string &in asTimer) {
SetMessage("Inventory","LucasMysteryEnterRoom",0);
}
void OnStart()
{
AddTimer("startlv",5,"EntryRoom");
PlayMusic("10_amb.ogg", true, 80, 1, 0, false);
AddUseItemCallback("", "Key_Marnica_01", "castle_3", "UsedKeyOnDoor", true);
}

{
SetEntityPlayerInteractCallback("human_skull_1", "OnPickup", true);
}

void Function(string &in entity)
{
PlaySoundAtEntity("scare_walk_ghost", "scare_walk_ghost.snt", "human_skull_1", 0, false);
}

void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("castle_3", false, true);
PlaySoundAtEntity("", "unlock_door", "castle_3", 0, false);
RemoveItem("Key_Marnica_01");
}
