         (This document covers version 1.0.2 of the 'Graduated Incrementor' behavior, current as of 2005-Aug-04)


         Description


         This behavior mimics the feedback shown by the ‘volume’ indicator on most TVs. It allows you to move the value of a property between a minimum and maximum value over a discrete number of steps.


         This behavior only affects the property when the

            Increment

         or

            Decrement

         actions are invoked (either via an action in the Studio interface or by calling the

            increment()

         or

            decrement()

         methods of this behavior directly).


         When invoking either action, you may specify the number of steps to take; the default is one step.


         The

            Property Name

         parameter is evaluated as a child of the parent object. (For example, “scale.z” refers to z attribute of the scale property of the parent object to which this behavior is attached.)


         Basic Properties


            Property Name


            The property to increment.


            Min Value


            The minimum value which may be set for the property.


            Max Value


            The maximum value which may be set for the property.


            Total Steps


            The number of steps to take between the min and max values.


         Actions


            Increment


            Increment the property towards the Max Value by a number of steps.


            steps


            The number of steps to take


            Decrement


            Increment the property towards the Min Value by a number of steps.


            steps


            The number of steps to take


         Events


            Value Changed


            Fires whenever Increment or Decrement are called.
