Creating "rotating buttons" in MIT App Inventor
This video is not targeted at children age 13 and younger. A reader asked if there might be a way to rotate a button on the screen. Sort of! Rather than use a Button control, we can use an ImageSprite and add to it an image to make the sprite look like a Button. Then, we can use the ImageSprite's Heading property to rotate the button on screen. To make the sprite work like a Button with a Click event handler, we use on the sprite Touch events to process "clicks".
