Still having no luck in moving a sprite in the direction it is pointing. My sprite moves a full 360 in 10 degree intervals. The sprite is located at variable was XPos and YPos. Trying to use sin and cos but with still no luck. Below is my function(which doesnt work of course) for moving the sprite in the particular direction it is facing. PLease anyone help. Really really need it. void cShip::ThrustShip(float speed) { double Radian; Radian = ShipAngle * 0.01745; //pi / 180 = 0.01745 VelX += sin(Radian) * speed; VelY -= cos(Radian) * speed; XPos += VelX; YPos += VelY; }

please do correct me if im wrong, but if ShipAngle follows normal circle ideas (what i know anyway 0 ->, 180 <-, 90 ^, etc.), cos would be the xpos and sin would be the ypos wouldnt it? mind u its 11pm here now and im on holidays so dont trust this judgement until u think about it...
