Building the LEGO Skeleton Behavior
As the LEGO Skeleton actors should behave like mindless zombies, we're going to have the Skeleton actor mindlessly follow the Main actor when the Skeleton enters the Main viewport.
Adding Gravity and Jump Behaviors Using Shortcuts

Updating the Jump Behavior
Like we did previously, we will update the Jump behavior event to fire during a random time interval between 2 and 8 seconds (see Figure 2-43).
Creating a Behavior to Follow the Main Actor
Next we'll create a new motion behavior that will make the Skeleton actors mindlessly follow the Main actor. To do this, create a new motion behavior for the Skeleton actor. Set the event for the motion behavior to be when the Main actor enters the viewport with the Skeleton actor, as shown in Figure 2-54.

Now that the Skeleton's motion will begin when the Main actor enters the scene, next let's configure what the particular motion will be when the event is fired. To do this, click the "Motion1" behavior's Motion button and set the "Relative to" value to the Main actor. When you do this, you'll notice ...
