改变动作执行对象CCTargetedAction通常默认的动作执行对象是调用runAction的对象，而CCTargetedAction可以改变动作执行对象。CCTargetedAction* t = CCTargetedAction::create(sprite2, moveto);sprite->runAction(CCSequence::create(moveto, t, moveto, NULL));sprite先moveto，然后sprite2执行moveto，最后sprite执行moveto。void ActionTargeted::onEnter(){ ActionsDem 阅读全文

摘要：
通过CCAnimation实例获取CCSpriteFrame，会出现类型转换问题。我们在创建一个animation的时候，经常遵循下面的步骤：1）create 一个CCArray对象A。2）通过A->addObject()添加CCSpriteFrame对象3）通过CCAnimation::createWithSpriteFrames(A， 0.2f)常见一个CCAnimation对象B。可以通过B->getFrames()获得一个CCArray*的指针A’，然后通过A’->ObjectAtIndex(0)获得第一个CCObject*类型的对象，称之为C。从表面上看，A’和A应 阅读全文
