Method Detail

processStimulus

public void processStimulus(java.util.Enumeration criteria)

This method is invoked by the behavior scheduler every frame. It maps the alpha value that corresponds to the current time into the appropriate light intensity for that time as obtained by interpolating between the light intensity values for each knot point that were passed to this class.

Specified by:

processStimulus in class Behavior

Parameters:

criteria - enumeration of criteria that have triggered this wakeup
