The next whole section tells the zombie to pursue the player and play the chase anima-
tion. The line animation.CrossFade(“Chase”); is of particular note, since it is a command
that creates a smooth transition between two animations—in this case, the idle animation
and the chase animation. This animation command is useful for a script that calls multiple
animations in a character or object. It also makes the zombie overshoot the player position
for an amount of time specified by extraRunTime . This is an element of the robot script from
the third-person platformer tutorial that was kept to make the zombie appear slow-witted.
