Hey all,

I am working on a new game and I have decided to try my hand at rotation. After looking at a few tutorials and learning, I came up with this: - handles the actual animation,rotation and movement of sprite - just a class that handles the default attributes that all sprites will share

And finally which just tests our code

The problem lies in my transform() method of

   public void transform() {
      //translate to center of component
      at.translate(this.getX() +  getImageWidth() / 2,
            this.getY() + getImageHeight() / 2);
      //do rotation
      //translate so the rotation occurs around the center of the object
      at.translate(-getImageWidth() / 2, -getImageHeight() / 2); //is something going wrong here?

When I rotate the image, it rotates but it doesn't seem to rotate around the center of the image as can be seen in the screenshot below:

Any help is appreciated but I will keep working on this. Thanks!

Found the problem... What a stupid mistake it was haha. My getImageWidth() and getImageHeight() were not returning the correct value of 48
