I have have a rotation problem in the Slick2d library, the image is just not rotating (ie I set a rotation but no result is shown). Here is the rotation code:

if (input.IsKeyDown(Input.KEY_LEFT))  {
    velocity.x = -1;

    rotation = (float)Math.toRadians(180);
}

That is meant to set the rotation of image to 180 degress.

Then I render the image with an origin of the center of the image:

image.setCenterOfRotation(image.getWidth() * scale / 2, image.getHeight() * scale * / 2);
image.setRotation(rotation);

image.draw(position.x, position.y, scale);

Any ideas? Thanks.

Are you trying to rotate the image over time or just set the rotation once when you're moving left? Because at best you're doing the latter right now. –  Tetrad Feb 21 '12 at 7:33
    
Rotate the image when you move left, so when you hit the left button the image is meant to rotate 180 degress instantly. Which isn't working. –  Darestium Feb 21 '12 at 8:24

As far as I know, Image.setRotation(float) accepts degrees, not radians. –  Bobby Feb 21 '12 at 8:48
    
Thanks! Works :) –  Darestium Feb 21 '12 at 8:52

Thanks Bobby!

Oh dear...I just confused Radians with Grads, otherwise I'd have posted that as answer anyway. :/ –  Bobby Feb 21 '12 at 9:02
