This is so helpful! Please do more breakdowns like this in the future!

Very good idea, I remember this to be quite confusing when starting out.

Wow, learned quite a few things here! Thank you!

Is there any chance that GM will fully support 3D in their engine? I think if they ignore it, their engine will suffer in the long term. It doesn’t have to be something huge, but it should at least be able to make something like *Buckshot Roulette*, *A Short Hike*, and so on. Yes, I know you can technically make 3D in it, but the level of programming required is just not suitable for most developers on your engine. I say all this because I love this engine and want it to continue.

can you tell us how to make the train move (top view)?

This isn't probably the best place to ask about this... But recently i noticed that there's a Linux version of the engine in beta. Is there any release date estimates for the final version?
I was planning on moving to Linux but was held back due to using to many programs that don't have a Linux version... But if Gamemaker has it, I'm more inclined to fully switch ASAP.

[sorry]

is the sub pixel draw origin point and sub pixel collision origin point still different ? Used to be that way and threw me off when rotating stuff... or is there a way to go about it that I didn't think of? Thanks!

Maybe make tutorials with Russia language?

can you make a video that just shows me how to make the first 80% of a game? ive had enough of "this... is called a variable... can you say variable?..." and enough of "look kid, first of all youre wrong, you cant make video games because you expect it to be like playing games because youre an idiot". like just how do i make something that actually does what i immagined instead of "the thing that results from me having followed a tutorial. i just ctrlc ctrlv at that point.
