ImageSprite, Canvas: Panning or scrolling background images

[Scott Ferguson]

Here is a way to have your app scroll a background. It simply involves changing the width of the image.

 

Screen Designer uses a canvas set to width: fill parent, and image sprite containing a wide image.

Have your program change the sprite width in increments that suits you. I used, 10 pixels per step. I could not get dragging the background to work, though.

Nice trick but doesn't seem to work in AI2

This is the method that I am currently using: https://groups.google.com/forum/#!category-topic/app-inventor-developers-library/GAoAzI6mDT0
