About setting the transparency of the sprite node in Cocos2d-x

1. When we need an elf as a larger container to store the other elves, let's set the size of the sprite first.

Settexturerect (Rect (0, 0, babysize.width, babysize.height));

But this will automatically fill the Genie's color with white.

2. This method is required at this time, when the number is 0 is completely transparent, 255 is completely opaque
SetOpacity (0);

3. You can then set its anchor point

Setanchorpoint (VEC2 (0,0));
