Creating behaviors (2)

A behavior can do anything

• Perform computations

• Update its internal state

• Modify the scene graph

• Start a thread

For example, a behavior to rotate a radar dish to track an object:

• On initialization, set initial wakeup criteria

• Get the object's location

• Create a transform to re-orient the radar dish

• Set a TransformGroup of the radar dish

• Set the next wakeup criteria

• Return
