Reader:
On Pg. 56 you have us type in the following code: _root.mcFrame = Math.round(Math.random() * 2 + 1);, then in the explanation on the same page you say that code should have been: _root.mcFrame = Math.round(Math.random() * 3);. While it looks similar I would expect that you would get different results due to the rules of precedence.

Author:
You are correct, there is a difference and a mistake in the description line. It should be Math.random()*2 +1 - not Math.random()*3, because we want the result to be from 1 to 3 instead of 0 to 2, we take the random of 2 and then add 1 to the result which will give us 1 to 3.
