cocos2d-x 动画循环播放

Question

一个动画从a点移动到b点，在移动过程中，动画需要循环播放。例如，一颗子弹移动到一个点，这个子弹是一个动画，应该循环播放。

CCSequence::create(
  CCSpawn::createWithTwoActions(
    CCTargetedAction::create(sprite, CCMoveTo::create(3.0f, point_a)), 
    CCTargetedAction::create(sprite, CCRepeatForever::create(CCAnimate::create(animation)))
),0);

但是CCRepeatForever不能是action sequence的成员。那怎么办呢？我用sequence是因为还有其他action要排队(上面略)

Answer 1

您不需要为此使用 ccspawn.. 也不需要 ccsequence 只对对象分别运行这两个操作。

CCSprite *newSprite=CCSprite::create("imageName");

CCAnimation *animation=CCAnimation::create();

//..some code to add frames to this animation object..

//to repeat for indefinite time you could setLoops to -1 or use CCRepeatForever class    //like this..
//1:

animation->setLoops(-1);
newSprite->runAction(CCAnimate:create(animation));

//or..

//2:

newSprite->runAction(CCRepeatForever:create(CCAnimate:create(animation)));

//now to translate this sprite simultaneously use this.

newSprite->runAction(CCMoveTo::create(3.0,point_a));
