[Other] Level scripts

[JosefigGaming]

Hey, I know how to make a level script, however, in oak's Lab, there is a Level Script that doesn't occur the first time you go in the lab, nor the 2nd nor the 3rd, etc. It happens after you try to leave Pallet Town and Oak brings you to his lab
Now, in DiegoisAwesome's XSE level script tutorial, he says a level script doesn't need to check, set or clearflag, so...
I can confirm that, since I opened that same script and he just cuts to the chase, no checkflag, no conditions, no nothing
Any help is appreciated :)

It occurs because the variable 0x4055 is set to 0x1 in the script where Oak stops you from leaving, which matches the "Flag" and "Value" of the level script for the lab.

So does that mean that if 0x4055 is 0x1, the level script will not occur? (in that specific case off course)
EDIT: Nevermind, I figured it out ;)
