cocos2d-x学习记录2——CCAction动作
CCAction能够使CCNode运动起来，能够呈现出多种多样的动作。这些动作能够改变其运动方向、形状、大小、旋转等。
同时，还可利用CCCallFunc、CCCallFuncN、CCCallFuncO、CCCallFuncND等函数实现回调。
MyScene.h代码
1 #ifndef MyScene_H_H 2 #define MyScene_H_H 3 4 #include "cocos2d.h" 5 using namespace cocos2d; 6 7 class MyScene : public CCLayer 8 { 9 public:10 static CCScene* createScene();11 virtual bool init();12 CREATE_FUNC( MyScene );13 14 void callback1();15 void callback2(CCNode *node);16 void callback3(CCObject *obj);17 void callback4(CCNode *node, void *data);18 19 20 private:21 };22 23 #endif
MyScene.cpp代码
1 #include "MyScene.h" 2 3 CCScene* MyScene::createScene() 4 { 5 CCScene *scene = CCScene::create(); 6 MyScene *layer = MyScene::create(); 7 scene->addChild(layer); 8 return scene; 9 };10 11 12 bool MyScene::init()13 {14 if( !CCLayer::init() ){15 return false;16 }17 18 CCSize size = CCDirector::sharedDirector()->getWinSize();19 CCSprite *sprite = CCSprite::create("pal4.png");20 sprite->setAnchorPoint( ccp(0.5, 0.5) );21 //sprite->setPosition( ccp(size.width/2, size.height/2) );22 sprite->setPosition( ccp(0, 0) );23 sprite->setScale(0.5f);24 sprite->setTag(2345);25 addChild(sprite);26 27 CCAction *action1 = CCMoveTo::create(1, ccp(size.width-sprite->getContentSize().width/2, size.height-sprite->getContentSize().height/2));28 CCAction *action2 = CCRotateBy::create(2, 360);29 CCAction *action3 = CCBlink::create(2, 5);30 CCAction *action4 = CCCallFunc::create( this, callfunc_selector(MyScene::callback1) );31 CCAction *action5 = CCCallFuncN::create( this, callfuncN_selector(MyScene::callback2) );32 CCAction *action6 = CCCallFuncO::create( this, callfuncO_selector(MyScene::callback3), sprite );33 CCAction *action7 = CCCallFuncND::create( this, callfuncND_selector(MyScene::callback4), "funcND" );34 35 CCArray *array = CCArray::createWithCapacity(8);36 array->addObject(action1);37 array->addObject(action2);38 array->addObject(action3);39 array->addObject(action4);40 array->addObject(action5);41 array->addObject(action6);42 array->addObject(action7);43 //array->addObject(NULL);44 //array->retain();45 //CCAction *totoalAction = CCSequence::create( action1, action2, action3, action4, action5, action6, action7, NULL );46 CCAction *totalAction = CCSequence::create(array);47 sprite->runAction(totalAction);48 49 return true;50 }51 52 void MyScene::callback1()53 {54 CCLog( "callback1" );55 }56 57 void MyScene::callback2(CCNode *node)58 {59 CCLog( "%d", node->getTag() );60 }61 62 void MyScene::callback3(CCObject *obj)63 {64 CCNode *node = dynamic_cast<CCNode*>(obj);65 if( node != NULL ){66 CCLog( "%d", node->getTag() );67 }68 }69 70 void MyScene::callback4(CCNode *node, void *data)71 {72 CCLog( "%d, %s", node->getTag(), data );73 CCMessageBox( "Over!", "Info" );74 }
callback1到callback4分别对应4种回调形式，只是各自带的参数不同而已。
