I think there is errata in Chapter 4.

p. 67 in the table: the "speed" argument does not report the speed of the ball or sprite as the chart says, it reports the speed of the swipe gesture (see the chart on the previous page).

p. 68 in the Learning Points: It says "speed is measured in how many pixels per interval ..." -- I think it should say "speed is measured in how many pixels per millisecond ..." If I understand correctly, the interval is how often the sprite position is updated on the screen, not how fast it is actually traveling. So interval influences how smoothly the movement appears, not the speed the sprite is actually going.

p. 69 "Canvas" setup in the chart does not indicate that the canvas should be set to "Fill Parent." But maybe this is assumed.

p. 74 The paragraph just above the learning points need to be edited. It relates to the "touched" event and the references to "flung" are incorrect.

I like the book! Perhaps not all of these are errors, but rather misunderstandings on my part. But I ran into what felt like some inconsistent descriptions in this chapter.

The previous poster is correct - the links to the images are broken. Also the Errata link in the second post (above) is broken too.

Thanks - I've raised it with the publisher again, hoping for a quick resolution.
