Hi

Could someone please give me a few pointers about using trig functions.

I have this sprite that rotates left and right, and what I want to do is
move it in the direction it is pointing when you press forward (up).

The way I thought of doing it is finding the angle the sprite is at from 0,
say (a), calculating using sin(a) and cos(a) to get the x and y distances to
move. However, I realise that the accuracy of this is no good, its either
going to be 0,0  1,1  1,0  or 1,1 and there's probably a whole bunch of
other
problems too. Basically I need a shove in the right direction (a big shove
maybe!)

Help!

Darren
