Differences between cocos2d-x3.0 and 2.0

Differences between cocos2d-x3.0 and 2.0

Difference 1. CC Removal

Difference 2. cc *** Structure Change

Difference 3. shared *** changes (the single-instance mechanism uses the syntax)

2.0CCSize winSize = CCDirector::sharedDirector()->getWinSize();SpriteFrameCache::sharedSpriteFrameCache()AnimationCache::sharedAnimationCache()NotificationCenter::sharedNotificationCenter()…3.0Size size = Director::getInstance()->getWinSize();SpriteFrameCache::getInstance()AnimationCache::getInstance()NotificationCenter::getInstance()…

Difference 4. POD category

Difference 5. Touch events

Auto dispatcher = Director: getInstance ()-> getEventDispatcher (); auto touchListener = listener: create (); touchListener-> onTouchBegan = CC_CALLBACK_2 (FBMainScene: onTouchBegan, this ); touchListener-> onTouchMoved = CC_CALLBACK_2 (FBMainScene: onTouchMoved, this); touchListener-> onTouchEnded = CC_CALLBACK_2 (FBMainScene: onTouchEnded, this); dispatcher-callback (TouchListener, this); bool FBMainScene: onTouchBegan (Touch * touch, Event * pEvent) {CCLOG ("onTouchBegan "); point point = this-> convertToWorldSpace (this-> convertTouchToNodeSpace (touch); return true;} void FBMainScene: onTouchMoved (Touch * touch, Event * pEvent) {CCLOG ("onTouchMoved");} void FBMainScene: onTouchEnded (Touch * touch, Event * pEvent) {CCLOG ("onTouchEnded ");} // The method for obtaining the contact has also changed: Point point = this-> c OnvertToWorldSpace (this-> convertTouchToNodeSpace (touch); // dispatcher control method: dispatcher-> addEventListener... Dispatcher-> removeEventListener (listener); dispatcher-> removeAllListeners ();

Difference 6. Callback Functions

The CC_CALLBACK_0 CC_CALLBACK_1 CC_CALLBACK_2 CC_CALLBACK_3 callback function carries different parameters for convenience

2.0 CCMenuItemFont * item = CCMenuItemFont: create ("back to the previous scenario", this, menu_selector (GameScene: backScene); 3.0 MenuItemFont * item = MenuItemLabel :: create ("return the previous scenario", CC_CALLBACK_1 (GameScene: backScene, this); // new callbacks based on C ++ 11 # define CC_CALLBACK_0 (_ selector __, __target __,) std: bind (& __ selector __,__ target __,#__va_args _) # define CC_CALLBACK_1 (_ selector __,__ target __,) std: bind (& __ selector __,__ target __, std: placeholders: _ 1, ##__va_args _) # define CC_CALLBACK_2 (_ selector __, __target __,) std: bind (& __ selector __,__ target __, std: placeholders: _ 1, std: placeholders: _ 2, ##__ VA_ARGS _) # define CC_CALLBACK_3 (_ selector __,__ target __,) std: bind (&__ selector __,__ target __, std: placeholders:: _ 1, std: placeholders: _ 2, std: placeholders: _ 3 #__va_args __)

Difference 7. CallFunc usage (using a "Function" Object)

CallFunc::create([&](){        Sprite *sprite = Sprite::create("s");        this->addChild(sprite);});

Difference 8. Replace copy with clone

2.0 CCMoveBy * action = (CCMoveBy *) move-> copy (); action-> autorelease (); 3.0 action = move-> clone (); autorelease is not required, the clone has been implemented.

Difference 9. Physics Integration physical Engine

Currently unavailable. box2d can be used in 3.0. You need to define PhysicsWorld, PhysicsBody, PhysicsShape, and PhysicsJoint in 3.0 Physics. Similar to box2d, You need to define CC_USE_PHYSICS before use.
