Detailed Description

CC RGBA protocol.

Member Function Documentation

- (BOOL) doesOpacityModifyRGB

[optional]

returns whether or not the opacity will be applied using glColor(R,G,B,opacity) or glColor(opacity, opacity, opacity, opacity);

Since:

v0.8

- (void) setOpacityModifyRGB:

(BOOL)

boolean

[optional]

sets the premultipliedAlphaOpacity property. If set to NO then opacity will be applied as: glColor(R,G,B,opacity); If set to YES then opacity will be applied as: glColor(opacity, opacity, opacity, opacity ); Textures with premultiplied alpha will have this property by default on YES. Otherwise the default value is NO

Since:

v0.8

- (void) updateDisplayedColor:

(ccColor3B)

color

recursive method that updates display color

- (void) updateDisplayedOpacity:

(GLubyte)

opacity

recursive method that updates the displayed opacity

Property Documentation

- (BOOL) cascadeColorEnabled [read, write, assign]

whether or not color should be propagated to its children

- (BOOL) cascadeOpacityEnabled [read, write, assign]

whether or not opacity should be propagated to its children

- (ccColor3B) color [read, write, assign]

sets and returns the color (tint)

Since:

v0.8

Reimplemented in CCLabelBMFont, and CCAtlasNode.

- (ccColor3B) displayedColor [read, assign]

returns the displayed color

- (GLubyte) displayedOpacity [read, assign]

returns the displayed opacity

- (GLubyte) opacity [read, write, assign]

sets and returns the opacity.

Warning:

If the the texture has premultiplied alpha then, the R, G and B channels will be modified. Values goes from 0 to 255, where 255 means fully opaque.

Reimplemented in CCLabelBMFont.
