Use glLookAt() instead. Complete information is found on www.gametutorials.com

i''ll try tnx :D

how i have to use gluLookAt ?!?!?!

The angle you are looking for is the angle between your player''s previous direction vector and the new one. Heres a diagram:




So lets say that you were going right so you clicked right. Your player starts to move in that direction. Then you click down, in order to rotate your player you need to find the angle between the old vector and the new vector and add it to the total of your player''s angle.

Check the net for how to find the angle between two vectors - its an extension of dot product i think.
