通过cocos2d 的代码
Block.h的代码
#include <iostream>
#include<cocos2d.h>
USING_NS_CC;
class Block:public Sprite
{
public:
    virtual bool init();
    virtual void update(float dt);
    CREATE_FUNC(Block);
};
Block.cpp代码
#include "Block.h"
bool Block::init()
{
    Sprite::init();
    Size s = Size(（rand()%20）+5,（rand()%30）+10);
    Size visibleSize = Director::getInstance()->getVisibleSize();
    setPhysicsBody(PhysicsBody::createBox(s));
    setTextureRect(Rect(0, 0, s.width, s.height));
    setContentSize(s);
    setPositionX(visibleSize.width);
    scheduleUpdate();
    return true;
}


void Block::update(float dt)
{
    this->setPositionX(getPositionX()-1);
    if(getPositionX()<0)
    {
        log(">>>");
        unscheduleUpdate();
        removeFromParent();
    }
}
这个案例中block虚函数怎样实现动态联编！
