[LVL ED] New Question: How to create a door

[Cruzore]

void FadeInFunction(string &in asTimer)
{
FadeIn(2);
}
{
AddEntityCollideCallback("Player", "cavein_area", "cavein_function", true, 1);
void cavein_function(string &in asParent, string &in asChild, int alState)
AddTimer("Timer_1", 2, "PlaySound");
}
no initiated function, nothing is doing those last 3 rows.
take the AddEntityCollideCallback("Player", "cavein_area", "cavein_function", true, 1);
and put it into OnStart()
I'll correct and post the whole script for you:
void OnStart()
{
AddUseItemCallback("", "stone_hammer_1", "shelf", "DestroyShelf", true);
AddEntityCollideCallback("Player", "cavein_area", "cavein_function", true, 1);
}
void DestroyShelf(string &in asItem, string &in asEntity)
{
//Do your stuff, whatever you want to do, here. Example:
FadeOut(2);
AddTimer("Timer_1", 2, "PlaySound");
}
void PlaySound(string &in asTimer)
{
PlaySoundAtEntity("", "break_wood.snt", "shelf", 0, false);
SetEntityActive("shelf", false);
SetEntityActive("book_row02_1", false);
SetEntityActive("book_row01_2", false);
SetEntityActive("book_pile01_1", false);
SetEntityActive("candlestick01_4", false);
SetEntityActive("book_row03_1", false);
SetEntityActive("book_open_1", false);
SetEntityActive("book_row02_2", false);
SetEntityActive("book_pile02_1", false);
SetEntityActive("book_pile01_2", false);
SetEntityActive("book_row02_3", false);
SetEntityActive("candlestick01_2", false);
SetEntityActive("candlestick01_3", false);
AddTimer("Timer_2", 1, "FadeInFunction");
}
void FadeInFunction(string &in asTimer)
{
FadeIn(2);
}

void cavein_function(string &in asParent, string &in asChild, int alState)
{
AddTimer("Timer_1", 2, "PlaySound");
}
void PlaySound(string &in asTimer)
{
PlaySoundAtEntity("", "explosion_rock_large.snt", "cave_in_1", 0, false);
SetEntityActive("cave_in_1", true);
}

By the way, you maybe want to play the cave in sound at yourself, since if that cave in is too far away, you won't hear it. Putting the sound by you, you hear it like if it's a huge explosion/cave in
