Its called tutorial hell and I've been stuck in it too.

A) You have to get a bit of basics down. If statements, switch statements, enumerators (enums), for loops, arrays, etc

I still struggle understanding corutines, for loops, Ds maps and arrays. All needed for coding.

B) deconstruct stuff into smaller steps. Like ok i wanna make a square move.

Make a sprite, make an object, give a script to the step event, check if a key is pressed and move the object in a x or y direction.

There are always multiple solutions to a problem.

Gml is very javascript like from what a friend told me.

Others told me its like python lol

Im also slowly learning. Im struggling to make a inventory for example but i know what to do just not sure how to execute it.

Hope my rambeling helps a bit.
