How do you do that pls?

Lol at that first code.

Code 1: When the door closes (for the first time) it will drain your sanity. You just change doorname to the name of your door in the Level Editor.

Code 2: Name a Scriptarea something and the door something, then place the Scriptarea somewhere within the door's closing path. Change the doorname and ScriptAreaname in the coding as appropriate.

SanityDec is nothing important except that function is called when the Door and Scriptarea collide. You don't need to change it.
