It’s hard to find general beginner’s game programming tips and articles that aren’t for experts or specific to unity or whatever. I know of a couple though, and will post them here, and will add more if I find any. I encourage others to do the same, along with a short description. Makes them easy to find later on!
‘Sin and cos, the programmer’s pals’ - It’s about the maths functions Sin(), Cos(), and atan() - used for rotating things and calculating angles between things using an (x,y) coordinate system. Good for twin stick shooters, racing games, rotating sprites, making wibbly sine waves, making circles, etc. Although it’s aimed at people using Allegro (a game programming library for C++), the examples are readable enough, and at least the first part of the article is required reading for anyone getting into this stuff, imho. https://www.helixsoft.nl/articles/circle/sincos.htm)
