Figure 2-2

Figure 2-2 shows only one scenario (that is one circle chasing one diamond). The
paragraph following it refers to "the scenario on the left" (wherein the prey is
sitting still), and "the scenario on the right" (in which the prey is moving along
some arbitrary path over time). Figure 2-2 only shows the first scenario.

Example 8-4

The first parameter to fi_GetData() needs closing quotation
marks. In other words,

intelligence[kTroll]=fi_GetData("Troll Settings.txt,
"INTELLIGENCE");
strength[kTroll]=fi_GetData("Troll Settings.txt,
"STRENGTH");
speed[kTroll]=fi_GetData("Troll Settings.txt,
"SPEED");

should be:

intelligence[kTroll]=fi_GetData("Troll Settings.txt",
"INTELLIGENCE");
strength[kTroll]=fi_GetData("Troll Settings.txt",
"STRENGTH");
speed[kTroll]=fi_GetData("Troll Settings.txt",
"SPEED");

states named A to F in 13-1.
