Hey, I remember before when I first tried making a top down game I had no damn clue on how to get the bullets to move towards my mouse. I was so desperate that I literally made about 50 if statements that checked for the mouse position (yeah, I had a lot of time on my hands). Then I learned about this magical unit circle and trig functions
I learned these functions in my math class, but luckly I'm an awesome dude and I made a tutorial which I personally think explained it well. But then again I know the topic so...
This tutorial uses images and displays I drew out for hopefully easy learning. Also I'm not giving you the code on how to make a bullet move in that direction. I'm teaching you how to use a very important function to get the way it should move. I don't know what library you use or what everyone's code looks like so I can't just say "Type bullet.move(atan2(blah))" because that wouldn't work for everyone, not even mine
Nice! I've pretty much figured out most of that before so I didn't learn anything from it, but it was very clear and I really wish I had found this (or it had been created) back when I couldn't figure it out.
It's nice to know that the technique that I use is the one that most people use! Also, I never really knew about the unit circle (going into Functions this year), so it was cool to see how all that worked out and was related to this.
