Script:
--------------------------------------------------------------------
void OnStart()
{
AddUseItemCallback("", "key_study_1", "castle_1", "UseKeyOnDoor", true);
AddEntityCollideCallback("Player", "ScriptArea_1", "Scary_1", true, 1);
AddEntityCollideCallback("Player","ScriptArea_2","Scary_2",true,1);
AddEntityCollideCallBack("Player","ScriptArea_3, "Scary_2",true,1);
}

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

void ScriptArea_1(string &in asItem, string &in asEntity)
{
PlaySoundAtEntity("", "enabled.snt", "Player", 0, false);
GiveSanityBoostSmall();
}
void Scary_1(string &in asParent, string &in asChild, int alState)
{
SetEntityActive("grunt1", true);
AddPropImpulse("grunt1", 10000, 0, 0, "world");
}

void Scary_2(string &in asParent, string &in asChild, int alState)
{
SetEntityActive("grunt2", true);
AddPropImpulse("grunt2", 10000, 0, 0, "world");
}

void ScriptArea_3(string &in asItem, string &in asEntity)
{
PlaySoundAtEntity("", "enabled.snt", "Player", 0, false);
GiveSanityBoostSmall();
}
void Scary_3(string &in asParent, string &in asChild, int alState)
{
SetEntityActive("grunt3", true);
AddPropImpulse("grunt3", 10000, 0, 0, "world");
}
