接着上一篇博文，前面讲到加载hero的实现，地图加载补充一下，

在HelloWorldScene.cpp的函数init()中添加如下代码：

int lvl=1;        char mapPath[20];        char lvlinform[30];        //map_tmx_lvl1        sprintf(mapPath,"mapTmx/map%d.tmx",lvl);        sprintf(lvlinform,"Lvl %d",lvl);        CCTMXTiledMap *map = CCTMXTiledMap::tiledMapWithTMXFile(mapPath);        //addChild(map,0,mapList);        if(!map)        {            CCLOG("map not init!");        }        map->setAnchorPoint(CCPointZero);        map->setPosition(ccp(0,50*(size.height/320)));//112.5        map->setScaleX(size.width/480);        map->setScaleY(size.height/320);        this->addChild(map,-2,mapList);

动作游戏，运动比较重要，讲一下运动的算法，在Global.h添加几个函数的定义：

void addBtn_Jump(CCMenuItemImage * pBtn_Jump);void addBtn_Right(CCMenuItemImage * pBtn_Right);void addBtn_Left(CCMenuItemImage * pBtn_Left);void addBtn_Attack(CCMenuItemImage * pBtn_Attack);void addBoy(Boy* boy);void addSwordPlayer(Player* swordPlayer);void addScene(CCLayer* gameScene);void addEnemyMap(CCTMXTiledMap *eMap);void addTiledMap(CCTMXTiledMap *kmap);void move(ccTime dt);

这几个函数的实现：

void Global::addBoy(Boy* boy){    this->boy=boy;}void Global::addBtn_Jump(CCMenuItemImage* pBtn_Jump){    this->pBtn_Jump=pBtn_Jump;}void Global::addBtn_Attack(CCMenuItemImage* pBtn_Attack){    this->pBtn_Attack=pBtn_Attack;}void Global::addBtn_Right(CCMenuItemImage* pBtn_Right){    this->pBtn_Right=pBtn_Right;}void Global::addBtn_Left(CCMenuItemImage* pBtn_Left){    this->pBtn_Left=pBtn_Left;}void Global::move(ccTime dt){                            if(pBtn_Right->getIsSelected()&&yVel==0&&boy->getDirection()!=ATTACK)    {        if(boy->getDirection()!=RIGHT)        {            boy->setAnimation(RIGHT,MOVE);                                        }                                    swordPlayer->getActorSprite()->setFlipX(false);                                    boy->getHeroSprite()->setFlipX(false);                            //-------------------2013.04.21----------------------------        boyDirection=RIGHT;        xVel=2.0;    }    else if(pBtn_Left->getIsSelected()&&yVel==0&&boy->getDirection()!=ATTACK)    {        if(boy->getDirection()!=LEFT)        {            boy->setAnimation(LEFT,MOVE);        }                                    swordPlayer->getActorSprite()->setFlipX(true);                                    boy->getHeroSprite()->setFlipX(true);                            //-------------------2013.04.21----------------------------        boyDirection=LEFT;        xVel=-1*2.0;    }    //默认开启跳跃    if(pBtn_Jump->getIsSelected())    {        if(boy->getDirection()!=JUMP&&yVel!=5.0)        {            boy->setAnimation(JUMP,MOVE);//影响帧数        }        yVel=5.0;    }    //测试    if(boy->getDirection()==JUMP)    {        //CCLOG(">-------------JUMP");    }    if(boy->getDirection()==OVERLOOK)    {        //CCLOG("<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
     
      getDirection()!=OVERLOOK&&xVel==0&&boy>getDirection()!=ATTACK&&boy->getDirection()!=ATTACKED)        {            //落地时，的设置            if(getStage()==GETSWORD)            {                boy->getHeroSprite()->setIsVisible(false);                swordPlayer->getActorSprite()->setIsVisible(true);            }            if(boy->getDirection()!=OVERLOOK)            {                boy->setAnimation(OVERLOOK,STAND);            }            //SWORDPLAYER ANIMATION            if(swordPlayer->getDirection()!=SWORDSTAND)            {                //CCLOG("SWORDSTAND      GROUND!");                swordPlayer->setAnimation(SWORDSTAND,MOVE);            }        }                                    time=0;    }    float gravity=0.1;    boyPosition.y=(yVel*time)-0.5*gravity*time*time;//导致下降    boyPosition.x=xVel*time;    if(boyPosition.x==201.0||boyPosition.x==-201.0)    {        //CCLOG("kuayue jiaozheng!");        boyPosition.x=0.0;    }    float y=boy->getHeroSprite()->getPosition().y;    if(boy->getHeroSprite()->getPosition().y
      
       getHeroSprite()->getPosition();        if(yVel==0)        {            position.y+=0.5*gravity*time*time;//导致上升，及一上一下(bug)        }        if(yVel>0)        {            time=0;        }                                    float x=boy->getHeroSprite()->getPosition().y;        xVel=0;        yVel=0;    }    boy>getHeroSprite()>setPosition(ccp(position.x+boyPosition.x,position.y+boyPosition.y));    swordPlayer>getActorSprite()>setPosition(ccp(position.x+boyPosition.x,position.y+boyPosition.y));    //CCLOG("BOY POSITION=%f",boy->getHeroSprite()->getPosition().x);    time+=0.75;}
      
     

在HelloWorldScene.cpp添加如下代码就可以让英雄动起来：

sGlobal->addBtn_Attack(pBtn_Attack);sGlobal->addBtn_Jump(pBtn_Jump);sGlobal->addBtn_Left(pBtn_Left);sGlobal->addBtn_Right(pBtn_Right);Global::getInstance()->addPlayer(p);Global::getInstance()->addBoy(player);Global::getInstance()->addScene(this);//动画的初始化AnimationManager::getInstance()->loadAnimation(heroAnimation,12);schedule(schedule_selector(HelloWorld::tick),0.005f);

再新建一个函数：

void HelloWorld::tick(cocos2d::ccTime dt) {      sGlobal->move(dt);}

现在hero可以动了。
