<CATEGORY Name="CustomStoryMain">
<Entry Name="Description">You are William, the gentleman. You have a weak memory where your location was, in your house. You woke up in a castle and you smell the stinky and dizzy smell.
-I need to escape, fast! I can't be here anymore!</Entry>

<CATEGORY Name="Journal">
<Entry Name="Note_PrisonIntro_Name">Read this!</Entry>
<Entry Name="Note_PrisonIntro_Text">If anybody sees this, then you are trapped! There is a shadow, no a monster patrolling in this castle. Watch out for him, if he sees you, escape, or atleast try! I also put a key around here that i made here, get it to unlock the door. Good luck my friend. [br]

00_castle.hps my HPS file

Spoiler below!

void OnStart()
{
AddUseItemCallback("", "key1", "castle_arched01_1", "UsedKeyOnDoor", true);
}

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

void OnEnter()
{

}

void OnLeave()
{

}

I'm using Notepad ++, but it won't work. When I am In-Game and picks up the key, it does not say "Handmade Rusty Key" and I can't see the description of it in the inventory. I would love you guys if you could help me, thanks!
