Scripts for beginners.

You're mistaken, BlueHeavenHero. It's not necessary to explicitly specify passing `nil` as a parameter (except in rare cases, which I can explain), as any undeclared value is initially considered `nil`. Therefore, the last three (or four) `nil` values can be omitted altogether. Furthermore, `REGION_ENTER_...` is a variable with a mnemonic name that stores the numerical ID of the trigger. And this number can be passed manually, as Loli Nikita did. Of course, if he made a mistake with the number and 6 refers to the trigger that changes the quest state, then you are right.
