Animation is displaying a sequence of two- or three-dimension art rapidly so that it appears to move. We've all watched cartoons; we know what that means.
What makes animation work is showing the sequence fast enough so that an optical illusion called persistence of vision occurs, and we see it as smooth motion. I love doing animation!
In App Inventor, we have two animation components: Ball and ImageSprite. We find them in the Animation drawer in the Palette column of Design (see next screenshot). These components work on the Canvas component (found in the Basic drawer).
Over time (a sequence), we can control their movement, position, color, image, what they bounce off, and more. Up until the most recent series of updates (see Changelog and Son of Changelog sections in the previous chapter), movement was restricted to two dimensions (up and down, left and right). Now, we also have z (backwards and forward) and can move back and forth in layers! Again, as I mentioned in the last...
