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是所有動作額父類，Spawn也是一個動作，只不過這個動作又可以包含若干個動作，最後一個引數是NULL值，因為Spawn的create函式引數是可變引數，需要用NULL值表示結束。.

Seqence是動作一個接著一個執行；

Spawn是動作一起執行。
