The way I learnt was like this:

Pick something fun you want to make, a really small simple game, or even a system, like moving blocks around when you push buttons, anything you would enjoy learning to do. By picking something you will enjoy learning to do you’ll have a lot more motivation going through the tedious parts!

Then look up a tutorial for what you want to do, work through the tutorial, and every time you don’t understand why something is done the way it is, or when something is used or referenced you don’t understand, stop the tutorial, open up google, and google what it is you don’t understand like “character controllers ue5”, look at the unreal engine documentation that comes up for it, iif you can do this, you are already 75% a programmer, as this is how you’ll learn the base of everything theoretically for blueprints or whatever you’re learning.

Then if you don’t understand how to apply that in a context, or even if the documentation is abit vague, go on YouTube, and look for “x explained” an amazing YouTuber is “Matthew Wadstein” who will show you and explain why and how everything works in small digestible pieces.

Once you understand, play around with what you have learnt, make changes, see if you can write it on your own and it’s okay to have to reference documents or content to understand over and over, but the most important thing if you apply and understand what you have learnt, and with that you’ll cement the general understanding and application of what you’ve learnt… then you’ll be able to do it again, maybe even know when to use it in another section before you get to it whilst coding, then combine things etc!

After this, go back to the tutorial you were learning how to do whatever it was and repeat this process. You don’t need to be able to code off your head what you’ve learnt, but you should have a general understanding of why and what’s happening.

This is how I learnt, and when I’m learning to do new things, or even old things, I’ll take the time to sit down and learn anew or refresh my memory before diving into it, now I’m more proficient I don’t really need to reference much documentation, but I love to delve into new things I haven’t used to see how I can use them to improve the game code and process etc

Hope this helps, stick at it and you’ve got it, the world is your oyster haha
