|This is a documentation subpage for Template:Motion Blocks (see that page for the template itself).
It contains usage information, categories and other content that is not part of the original template page.
This navbox template should be placed at the bottom of the page, but above the page's category. It is placed on pages that talk about different Motion Blocks in Scratch, such as the Set Y to () block.
If on Edge, Bounce (block)
The If on Edge, Bounce block is a Motion Block and a Stack Block. The block checks to see if its sprite is touching the edge of the screen with the move steps block — and if it is, the sprite will point in a direction that mirrors the direction from which it is coming.
