COCOS2D方法回调，块语句回调和反转动作和特殊动作

1.今天学习了有关动作的回调的内容。 1）就方法回调进行说明：简单的说 就是使用了SEL 选择器方法 ~~~ -(id) init { // always call "super" init // Apple recommends to re-assign "self" with the "super's" return value if( (self=[super init]) ) { //获取当前屏幕的大小 CGSize size = [CCDirector sharedDirector].winSize; // 创建第一个精灵，并将其添加为当前层的子节点 apple = [CCSprite spriteWithFile:@"apple.png"]; apple.position = ccp(50,100); apple.opacity = 0; [self addChild:apple]; // 创建第二个精灵，并将其添加为当前层的子节点 plane = [CCSprite spriteWithFile:@"plane.png"]; plane.position = ccp(size.width/2,size.height/2); plane.opacity = 0; [self addChild: plane]; // 创建第三个精灵，并将其添加为当前层的子节点 ball = [CCSprite spriteWithFile:@"ball.png"]; ball.position = ccp(250,100); ball.opacity = 0; [self addChild:ball]; // 创建第四个精灵，并将其添加为当前层的子节点 orange = [CCSprite spriteWithFile:@"orange.png"]; orange.position = ccp(250,300); orange.opacity = 0; [self addChild:orange]; // 创建第五个精灵，并将其添加为当前层的子节点 tomato = [CCSprite spriteWithFile:@"tomato.png"]; tomato.position = ccp(250,200); tomato.opacity = 0; [self addChild:tomato]; // 第一个精灵执行序列组合动作，其中最后一个动作调用了moveSprite方法 [apple runAction:[CCSequence actions:[CCDelayTime actionWithDuration:1], [CCSpawn actions: [CCFadeIn actionWithDuration:1], [CCScaleTo actionWithDuration:1 scale:1.5], nil], [CCDelayTime actionWithDuration:1], [CCCallFunc actionWithTarget:self selector:@selector(moveSprite)], nil]]; // 第二个精灵执行序列组合动作，其中最后一个动作调用了removeSprite:方法，并将当前的节点对象传递给指定的方法，注意冒号不能省略 [plane runAction:[CCSequence actions:[CCDelayTime actionWithDuration:1], [CCSpawn actions: [CCFadeIn actionWithDuration:1], [CCScaleTo actionWithDuration:1 scale:1.5], nil], [CCDelayTime actionWithDuration:1], [CCCallFuncN actionWithTarget:self selector:@selector(removeSprite:)], nil]]; // 第三个精灵执行序列组合动作，其中最后一个动作调用了tintSprite:data:方法，并将当前的节点对象和数据传递给指定的方法，注意冒号和参数不能省略 [ball runAction:[CCSequence actions:[CCDelayTime actionWithDuration:1], [CCSpawn actions: [CCFadeIn actionWithDuration:1], [CCScaleTo actionWithDuration:1 scale:1.5], nil], [CCDelayTime actionWithDuration:1], [CCCallFuncND actionWithTarget:self selector:@selector(tintSprite:data:)data:(void *)2], nil]]; // 第四个精灵执行序列组合动作，其中最后一个动作调用了tintSprite:data:方法，并将当前的节点对象和数据传递给指定的方法，注意冒号和参数不能省略 [orange runAction:[CCSequence actions:[CCDelayTime actionWithDuration:1], [CCSpawn actions: [CCFadeIn actionWithDuration:1], [CCScaleTo actionWithDuration:1 scale:1.5], nil], [CCDelayTime actionWithDuration:1], [CCCallFuncO actionWithTarget:self selector:@selector(rotateSprite:object:) object:tomato], nil]]; } return self; } ~~~ 2.块语句回调：一句话就是在代码中嵌入了 block语句 ~~~ -(id) init { // always call "super" init // Apple recommends to re-assign "self" with the "super's" return value if( (self=[super init]) ) { // ask director for the window size CGSize size = [[CCDirector sharedDirector] winSize]; // 创建第一个精灵，并将其添加为当前层的子节点 apple = [CCSprite spriteWithFile:@"apple.png"]; apple.position = ccp(50,100); apple.opacity = 0; [self addChild:apple]; // 创建第二个精灵，并将其添加为当前层的子节点 plane = [CCSprite spriteWithFile:@"plane.png"]; plane.position = ccp(size.width/2,size.height/2); plane.opacity = 0; [self addChild: plane]; // 创建第三个精灵，并将其添加为当前层的子节点 ball = [CCSprite spriteWithFile:@"ball.png"]; ball.position = ccp(250,100); ball.opacity = 0; [self addChild:ball]; // 创建第四个精灵，并将其添加为当前层的子节点 orange = [CCSprite spriteWithFile:@"orange.png"]; orange.position = ccp(250,300); orange.opacity = 0; [self addChild:orange]; [apple runAction:[CCSequence actions:[CCDelayTime actionWithDuration:1], [CCSpawn actions: [CCFadeIn actionWithDuration:1], [CCScaleTo actionWithDuration:1 scale:1.5], nil], [CCDelayTime actionWithDuration:1], [CCCallBlock actionWithBlock:^{ [apple runAction:[CCMoveTo actionWithDuration:2 position:ccp(50, 200)]]; }], nil]]; [plane runAction:[CCSequence actions:[CCDelayTime actionWithDuration:1], [CCSpawn actions: [CCFadeIn actionWithDuration:1], [CCScaleTo actionWithDuration:1 scale:1.5], nil], [CCDelayTime actionWithDuration:1], [CCCallBlockN actionWithBlock:^(CCNode *node){ CCNode *currentNode = node; [self removeChild:currentNode cleanup:YES]; }], nil]]; [ball runAction:[CCSequence actions:[CCDelayTime actionWithDuration:1], [CCSpawn actions: [CCFadeIn actionWithDuration:1], [CCScaleTo actionWithDuration:1 scale:1.5], nil], [CCDelayTime actionWithDuration:1], [CCCallBlockO actionWithBlock:^(id object){ CCNode *currentNode = (CCNode *)object; [currentNode runAction:[CCSequence actions:[CCFadeIn actionWithDuration:2],[CCRotateBy actionWithDuration:3 angle:180], nil]]; } object:orange], nil]]; } return self; } ~~~ 3.反转动作：如果一系列动作有顺序，那么反转动作就是原来动作的逆向run 与 CCReverseTime 有关 4.特殊动作 CCActionTween  主要是修改一个对象的属性，比如说  scale，width等 id scaleA = 【CCScale actionWithDuration ：2 scale：3】； id scaleB = 【CCActionTween actionWithDuration：2 key： @“Scale” form 1：to：3】; CCSpeed 可以修改一个飞机的速度。
