Batch Processing genie in Cocos2d-X

Batch Processing genie in Cocos2d-X

Batch Processing genie using common methods

Add the following code to Sprite. h:

# Ifndef _ Sprite_SCENE_H __# define _ Sprite_SCENE_H __# include "cocos2d. h "USING_NS_CC; class Sprite: public CCLayer {public: // initialization layer bool init (); // create a scenario static CCScene * scene (); // respond to the touch bool Sprite :: ccTouchBegan (CCTouch * touch, CCEvent *); // used to create: CREATE_FUNC (Sprite);}; # endif/_ Sprite_SCENE_H __

Add the following code to Sprite. cpp:

# Include "Sprite. h "USING_NS_CC; // create scenario CCScene * Sprite: scene () {// create scenario CCScene * scene = CCScene: create (); // create a layer Sprite * layer = Sprite: create (); // Add the layer to the scene-> addChild (layer); // return scene ;} // initialize the instance handle bool Sprite: init () {// initialize the parent CCLayer: init (); // obtain the window size CCSize winSize = CCDirector :: shareddire()-> getWinSize (); // sets the coordinate CCPoint ptCenter = ccp (winSize. width/2, winSize. height/2); // create a batch processing node container CCSpriteBatchNode * batch = CCSpriteBatchNode: create ("CloseNormal.png"); // Add the genie to the layer addChild (batch ); // use textures to create the sprite * sprite = CCSprite: createWithTexture (batch-> getTexture (); // Add the sprite to the container batch-> addChild (sprite ); // set the sprite position Sprite-> setPosition (ptCenter); // set the touch setTouchEnabled (true); setTouchMode (kCCTouchesOneByOne); return true;} // response to the touch bool sprite :: ccTouchBegan (CCTouch * touch, CCEvent *) {// obtain the window size. CCSize winSize = CCDirector: sharedDirector ()-> getWinSize (); // 100 cycles, create 1000 genie for (int I = 0; I <1000; I ++) {// create genie CCSprite * sprite = CCSprite: create ("CloseNormal.png "); // Add the genie to the layer addChild (sprite); // set the sprite position sprite-> setPosition (ccp (CCRANDOM_0_1 () * winSize. width, CCRANDOM_0_1 () * winSize. height);} return true ;}

Execution result:

1. Effect After opening the program: The frame rate is 58.7 after the program is started

Batch Processing genie using textures

Add the following code to Sprite. h:

# Ifndef _ Sprite_SCENE_H __# define _ Sprite_SCENE_H __# include "cocos2d. h "USING_NS_CC; class Sprite: public CCLayer {public: // initialization layer bool init (); // create a scenario static CCScene * scene (); // respond to the touch bool Sprite :: ccTouchBegan (CCTouch * touch, CCEvent *); CCSpriteBatchNode * _ batch; // used for creating: scenes, menus, layers, and other things CREATE_FUNC (Sprite );}; # endif/_ Sprite_SCENE_H __

Code in Sprite. cpp

# Include "Sprite. h "USING_NS_CC; // create scenario CCScene * Sprite: scene () {// create scenario CCScene * scene = CCScene: create (); // create a layer Sprite * layer = Sprite: create (); // Add the layer to the scene-> addChild (layer); // return scene ;} // initialize the instance handle bool Sprite: init () {// initialize the parent CCLayer: init (); // obtain the window size CCSize winSize = CCDirector :: shareddire()-> getWinSize (); // sets the coordinate CCPoint ptCenter = ccp (winSize. width/2, winSize. height/2); // batch processing genie CCSpriteBatchNode * batch = CCSpriteBatchNode: create ("CloseNormal.png"); addChild (batch); _ batch = batch; CCSprite * sprite = CCSprite:: createWithTexture (batch-> getTexture (); batch-> addChild (sprite); sprite-> setPosition (ptCenter); setTouchEnabled (true); setTouchMode (kCCTouchesOneByOne ); return true;} // response to the touch bool Sprite: ccTouchBegan (CCTouch * touch, CCEvent *) {CCSize winSize = CCDirector: sharedDirector ()-> getWinSize (); for (int I = 0; I <1000; I ++) {CCSprite * sprite = CCSprite: createWithTexture (_ batch-> getTexture ()); _ batch-> addChild (sprite); sprite-> setPosition (ccp (CCRANDOM_0_1 () * winSize. width, CCRANDOM_0_1 () * winSize. height);} return true ;}

Execution result:

1. Effect After opening the program: The frame rate is 58.7 after the program is started

2. After multiple clicks, the frame rate does not change significantly

Note: CCSpriteBatchNode is also a container, but it can only accommodate CCSprite objects and requires these genie to come from the same texture.
