How do you make a monster spawn and then he leaves and you can hear a door opened.

i already know what to do ^-^
i create another area and use the AddEntityCollideCallback
then im going to create a function called LookAt.
And add a timer that chances the function LookAt
cause i need to deactivate or else his just going to look at that point.
I think thats it.
Also is there a script function that turns off the lights?
