CCNodeGradient Class Reference

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

Overview

Draws a rectangle filled with a gradient.

The gradient node adds the following properties to the ones already provided by CCNodeColor:

If no vector is supplied, it defaults to (0, -1) - fading from top to bottom. Color is interpolated between the startColor and endColor along the given vector (starting at the origin, ending at the terminus).

Creating a Gradient Node

+ nodeWithColor:fadingTo:

Creates a full-screen CCNode with a gradient between start and end color values.

+ (instancetype)nodeWithColor:(CCColor *)start fadingTo:(CCColor *)end

Parameters

start

Start color.
end

End color.

Return Value

The CCNodeGradient Object.

Parameters

start

Start color.
end
