I picked up the Zenva bundle from Humble and I've done the first two classes and I feel like I learned a little, but the classes have failed to actually teach me much of anything about GDScript. I don't understand why I typed what I typed or how to use the code I did "learn" so far.
Any recommendations for other tutorials or something I could read to learn more? Maybe a book or a website of written tutorials.
I'm going to continue with the courses, but I feel like I'm not going to get much out of them.
From other comments it sounds like you're trying to run before you can walk. Make a hello world program in all top 20 languages. Make a fizzbuzz in all top 20. Get a grasp of how a computer works. A game will always push forward until it hits a bottleneck - learn to recognise it.
Good luck!
