Chapter 7: Example 7-5, p. 117

In example 7-5 (Zoog with functions), a line of code is commented out by accident:

Incorrect

// mouseX position determines speed factor for moveZoog function
// float factor = constrain(mouseX/10,0,5);
jiggleZoog(factor);

Correct

// mouseX position determines speed factor for moveZoog function
float factor = constrain(mouseX/10,0,5);
jiggleZoog(factor);
