1. I learned about several main classes: Director (Director), Scene (scenario), Layer (Layer), and Sprite (genie );

2. Create a Wizard:

CCSize visiblesize = CCDirector: sharedDirector ()-> getVisibleSize ();
CCSprite * sprite = CCSprite: create ("sprite.png ");
Sprite-> setPosition (ccp (visiblesize. width/2, visiblesize. height/2 ));
This-> addChild (sprite );

3. Modify the background color of the layer:

If (! CCLayerColor: initWithColor (ccc4 (255,255,255,255 ))){
Return false;} // because it is not convenient to set the color in CCLayer, It inherits its subclass CCLayerColor. Because init () cannot contain parameters, initWithColor (ccp (x, y, z, w); the first parameter indicates red, the second parameter indicates green, the third parameter indicates blue, and the fourth parameter indicates completely opaque.
