... Animation . Arrow . ... I created the first animation by running Script-Fu / Animators / Fire on the head of an arrow. ... I merged the animation with the background image, and specified a final X offset of -128 (the background is 128 pixels wide). This results in an animation with a nice moving background. Note that you can also use a background that is wider than the image, as long as you specify the width of the background for the final X offset if you want the final animation to loop. ...
