Problem

[darkadders]

ill try fixing it for ya:


void OnStart()
{
AddUseItemCallback("", "key_1", "Door_3", "UsedKeyOnDoor", true);
}


void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("Door_3", false, true);
PlaySoundAtEntity("", "unlock_door.snt", "Door_3", 0, false);
RemoveItem("key_1");
}





WHAT I DID (along with some unrelated tutorial information on further development.)

I basically changed the script from void OnEnter to void OnStart.

Also, i added a function for your AddUseItemCallback. so when you use the item on the AddUseItemCallback, it will call the function of UsedKeyOnDoor, which: unlocks the door, plays the sound "unlock_door.snt" and removes the key item from your inventory

i also added some ""s here and there where theyre needed. true's and false's dont need "".

and i also changed some typos in your item names.

REMEMBER: you need to have a filetype for your sound which you want played.

the default filetypes of both sounds and music in amnesia is .ogg

a SOUND uses .snt files
MUSIC uses .ogg files

if you want a quick tutorial on filetypes, click the spoilerbutton below, if interested.

Spoiler below!

a .SNT file is a file which tells the script what sounds which are to be played.

example: lets say i have 6 sounds named "MYSOUND_1.ogg", "MYSOUND_2.ogg", "MYSOUND_3.ogg", "MYSOUND_4.ogg", "MYSOUND_5.ogg"
and "MYSOUND_6.ogg".

id probably want these sounds to play at random, to add some realism to the sounds (when you hit something, it doesnt make the same sound all the time, it maks a variety of sounds), so i make a .snt file for these sounds, named MYSOUND.snt

i open another .snt made already, and i copy its contents and paste it into mine. i customise the names of the sounds being played from "whatever_sounds_its_told_to_play_at_random" to "MYSOUND_1,2,3,4,5,6"

this will tell the game to play the MYSOUND sounds at random.

music doesnt need a .snt file to be played. to play music you just copy the script from the list on the wiki and type in the music name, with a .ogg filetype.

this script can be copied from my post if you wish. it should be functioning now.

Just remember what ive typed here, and i hope you'll learn from the things i have done and explained.

good luck on your story ^^
