Im trying to make a basic top-Down game where the player rotates to face the direction that it is moving, like you would expect to see in asteroids or GTA 1.  Pretty easy stuff hey...
Regardless, I am getting really stuck with what I need to do to get the angle that I need to rotate my character.  I've been digging through all my old maths books and the internet but just can't seem to get a clear answer on what exactly I need to do and my experimentation are going quite badly.  I would like to give you more specifics on where I get stuck but unfortunately it seems to be "all of it"

the direction you want is given by trigonometry. use atan2, which is usually present in whatever maths library you're using.

That is sweet! I had so many variations on atan2(dx,dy)*(180/pi) at the beginning of the evening without quite getting it, and slowly worked further and further away from the solution    Oh well at least I learned (and relearned) some stuff about triangles.  Thanks

yeah, atan2 is a good thing to have. Anyways, please remember that you should store the angle in radians as long as you are not displaying it. This willmake your life a hell lot easier
