there's a lost soul at Discord. He/she obviously got lots of informations from your Tutorial Lesson 17 (Movement and Rotation).
From a quick visit to that lesson I see for your teachings you use (for whatever reason) a modified version of the standard math coordinate system, which assumes 0° as north direction and then counts the angles clockwise.
Now, this guy/girl is trying to calculate the angle from one point to another one using the _ATAN2 function and wonders about the results, mayby you could have a look: https://discord.com/channels/97538191235...0559666196
Steve and me tried to help, but as his/her thinking is obviously compromised by your coordinate modell, we probably made it even worse than better.
Yes, Lesson 17 has caused troubles for a few because of the way I orient the coordinate system. The reason I did that is because 99% of the people that visit the tutorial want nothing to do with the math and just want north, 0 degrees, to face up like the real world.
Those that understand the math understand what I've done here. Those that want to learn the math (which is surprisingly few) get confused as the user you are pointing out.
What to do, what to do.
I need to update Lesson 17 with a section on how the coordinate actually looks and why it needs to be modified for screen use. I'll log into discord and try to explain. Thank you for bringing this to my attention.
UPDATE: OK, I can't log into Discord? I get a popup after putting my user name and password in asking me to verify I'm human but nothing to do to verify?
