[SCRIPT] I need a help please

[Straxedix]

Ok what i wanna and what i try to do is to make a script when player enter some kinda room and step there are 2 areas (i make it so same when he enter 1 he will enter and 2 area in the same time) so the area 1 should make him look back what it does,so while he is looking back or turning around then timer from area 2 should react so then doors HARD close and lock so there is 1 key in room and when i make it pick up just to pick up key doors unlock (without using key)

My .hps

Spoiler below!

void OnStart()

{
AddEntityCollideCallback("Player", "CloseDoor", "CollideLockDoor", true, 1);
AddEntityCollideCallback("Player", "Area01", "LookBack01", true, 1);
AddTimer("DoorDown", 3, "CollideLockDoor");
}

void LookBack01(string &in asParent, string &in asChild, int alState)
{
StartPlayerLookAt("Door01", 2, 25, "CallbackName");
AddTimer("", 3, "StopLookingAtDoor");
}

void StopLookingAtDoor(string &in asTimer)
{
StopPlayerLookAt();
}

void CollideLockDoor(string &in asParent, string &in asChild, int alState)
{
SetSwingDoorLocked("Door01", true, true);

PlaySoundAtEntity("bang", "scare_slam_door", "castle_1", 0.0f, false);
StartScreenShake(0.02f, 1.0f, 0.5f, 1.0f);
}
