com.jme3.math.ColorRGBA
ColorRGBA defines a color made from a collection of red, green and blue values. An alpha value determines is transparency. All values must be between 0 and 1. If any value is set higher or lower than these constraints they are clamped to the min or max. That is, if a value smaller than zero is set the value clamps to zero. If a value higher than 1 is passed, that value is clamped to 1. However, because the attributes r, g, b, a are public for efficiency reasons, they can be directly modified with invalid values. The client should take care when directly addressing the values. A call to clamp will assure that the values are within the constraints. @author Mark Powell @version $Id: ColorRGBA.java,v 1.29 2007/09/09 18:25:14 irrisor Exp $
