In terms of tank controls

Tank controls are:

W - move forward 2 pixels

A - rotate 1 degree counter clockwise

D - rotate 1 degree clockwise

But the backward movement is escaping me. I tried moving toward angle, but that isn't looking good. Is there a "move backward" action that I'm just not seeing?

I've went through all of the angle actions and the position under size and position.

Thanks for any tips on this.

Didn't see one post. Negative "forward" for backward movement.
