Hi, in my top down 2d game i want it so that when the mouse is moved the player rotates to face the cursor. My problem is that i don''t know how to use the coordinates to determine the angle the player will face. Does anyone know how to do this or have any suggestions? +AA_970+

using tan, of course!
first, figure out the x disntance between the mouse and the player, and the y distance between the mouse and the player. then use the formula:

tan x = y/x

then use the special arctan function using y/x to find x, which is the angle.

Thanks alot!!!
I should probably get used to dealing with trig.

please remember to use tan, and arctan look up tables to speed up the game so cpu time can be used elswhere (it'' always nice to have better AI)

I have always been lost!
