cocos2d-x学习笔记（10）重复动作RepeatForever和Repeat 以及动作组合Sequence和Spawn

Repeat和RepeatForever

Sprite* sprite=Sprite::create("sprite.png");
sprite->setPosition(Point(visibleSize.width/2,visibleSize.height/2));
this->addChild(sprite,1);

JumpBy* jumpBy=JumpBy::create(3.0f,Point(50,1),100,1);

//RepeatForever* repeatforeverAction=RepeatForever::create(jumpBy);

Repeat* repeatAction=Repeat::create(jumpBy,3);

sprite->runAction(repeatAction);


Sequence和Spawn

Sprite* sprite=Sprite::create("sprite.png");
sprite->setPosition(Point(visibleSize.width/2,visibleSize.height/2));
this->addChild(sprite,1);

MoveBy* moveBy=MoveBy::create(2.2f,Point(40,20));

JumpBy* jumpBy=JumpBy::create(3.0f,Point(50,1),100,5);

RotateBy* rotateBy=RotateBy::create(2.5f,220,10);

Action* action=Spawn::create(moveBy,jumpBy,rotateBy,NULL);

sprite->runAction(action);

Action是所有动作额父类，Spawn也是一个动作，只不过这个动作又可以包含若干个动作，最后一个参数是NULL值，因为Spawn的create函数参数是可变参数，需要用NULL值表示结束。.

Seqence是动作一个接着一个执行；

Spawn是动作一起执行。
