cocos2d, CCRenderTexture small problem

- (CCSprite *) spriteWithColor: (ccColor4F) bgColor textureSize: (float) textureSize {

/ / 1: Create new CCRenderTexture
CCRenderTexture * rt = [CCRenderTexture renderTextureWithWidth: textureSize height: textureSize];

/ / 2: Call CCRenderTexture: begin
[Rt beginWithClear: bgColor.r g: bgColor.g b: bgColor.b a: bgColor.a];

/ / 3: Draw into the texture
/ / We'll add this later

/ / 4: Call CCRenderTexture: end
[Rt end];

/ / 5: Create a new Sprite from the texture
return [CCSprite spriteWithTexture: rt.sprite.texture];

}
If that last rt.sprite.texture written in C + +, it should be how to change, big thank you God

CCSprite :: spriteWithTexture (rt-> getSprite () -> getTexture ());
