Studying how the actual game works, in gsc, is very useful as well.
And also allows you to do all kinds of cool stuff, like replace some behavior when something happens, or maybe re-use some of the gsc that's already in the game so you don't need to custom make everything.

The stickied post in here has a download to a gsc dump. Then also get get some program that searches for text from inside multiple files. Useful when you're looking for something specific, or want to see where some function is defined, where it's called, etc etc etc. Been using "AstroGrep" myself to do this.

Yea i had that issue before but

if you look at the code :
-You are going to call it if you spawn
-Only moves the barriers that have a lower z axis that you have after you spawned

there is no way you are going to die after adding the code

but the most importent thing is to call it on onPlayerSpawned
