[Discuss] Gettings Players YAW using D3D. topic

Hellowww folks, as i declare myself completly retarted for not being able to find something using search engine ( lulz) i have a question.

I did a radar, wrote a pseudo for rotation, ( basic sin and cos).
The went to do my radar rotation, and... faq! Realised i Need the angle,( aka yaw, which i then can convert to radians or degrees).

Is there a way of getting this yaw through d3d?
