Where should I look? So far I’ve found out how to calculate magnitude manually
D = sqrt((x2 - x1)^2… bla bla
I basically wanna learn stuff related to math and physics like maybe velocity and all that kinda stuff. I’m basically trying to figure out how things actually work in 3d space, as I’m aiming to make some decent projects.
I assume your talking about Trigonometry, as its useful for many things in game development.
You should be able to take trigonometry classes in high school, which would be the best way to learn it. If you are nowhere close to high school, you could try to teach it to yourself using online resources.
