推荐答案

易...

要做到这些动画ü必须记住，你的动画精灵的Z值应该更高了所有其他人总是前面（创建常量来表示）
你要使用CCAction确实创造了类似的行动，淡入，缩放，移动。

To do those animations u must be in mind that the z value of your animated sprite should be higher the all the others to be always up front (create constants to that) You are going to use CCAction do create the action like, fadeIn, Scale, Move.

这是一个海盗的样品中的屏幕和像

This is a sample of an viking poping up in the screen and like

CCSprite *viking =
[CCSprite spriteWithFile:@"VikingFloating.png"];
[viking setPosition:ccp(screenSize.width * 0.35f, screenSize.height * 0.45f)];
[self addChild:viking];
id rotateAction = [CCEaseElasticInOut actionWithAction:
[CCRotateBy actionWithDuration:5.5f angle:360]];
id scaleUp = [CCScaleTo actionWithDuration:2.0f scale:1.5f];
id scaleDown = [CCScaleTo actionWithDuration:2.0f scale:0.5f];
[viking runAction:[CCRepeatForever actionWithAction:
[CCSequence actions:scaleUp,scaleDown,nil]]];
[viking runAction:
[CCRepeatForever actionWithAction:rotateAction]];
