Hi, I am trying to do a asteroids clone and just having problems moving my ship in the direction it is facing in. I know about sin and cos and have been playing around with them with little success, and would appreciate help.

from your trig class:

x = r cos theta
y = r sin theta

float angle;   // current bearing, 0 = vertical (x axis), positive clockwisefloat posX;float posY;void move( float distance ){  posX += cos(angle) * distance;  posY += sin(angle) * dishance;}
