com.ardor3d.util.stat.graph.DefColorFadeController

All Implemented Interfaces:

SpatialController<Spatial>

public class DefColorFadeController
extends Object
implements SpatialController<Spatial>

A controller that changes over time the alpha value of the default color of a given Geometry. When coupled with an appropriate BlendState, this can be used to fade in and out unlit objects.

An example of an appropriate BlendState to use with this class:

 BlendState blend = new BlendState();
 blend.setBlendEnabled(true);
 blend.setSourceFunction(SourceFunction.SourceAlpha);
 blend.setDestinationFunction(DestinationFunction.OneMinusSourceAlpha);

DefColorFadeController

public DefColorFadeController(Mesh target,
 float targetAlpha,
 double rate)

Sets up a new instance of the controller. The

Parameters:

target - the object whose default color we want to change the alpha on.

targetAlpha - the alpha value we want to end up at.

rate - the amount, per second, to change the alpha. This value will be have its sign flipped if it is not the appropriate direction given the current default color's alpha.

Parameters:

time - The time in seconds between the last call to update and the current one

caller - The spatial currently executing this controller.
