CCNodeGradient Class Reference

Inherits from	CCNodeColor : CCNode : CCResponder : NSObject
Declared in	CCNodeColor.h

Overview

CCNodeGradient is a subclass of CCNodeColor that draws gradients across the background.

All features from CCNodeColor are valid, plus the following new features: - direction - final color - interpolation mode

Color is interpolated between the startColor and endColor along the given vector (starting at the origin, ending at the terminus).

If no vector is supplied, it defaults to (0, -1) – a fade from top to bottom.

If ‘compressedInterpolation’ is disabled, you will not see either the start or end color for non-cardinal vectors; a smooth gradient implying both end points will be still be drawn, however.

If ‘ compressedInterpolation’ is enabled (default mode) you will see both the start and end colors of the gradient.
