关于Cocos2d-x中根据分数增加游戏难度的方法

1.GameScene.h中声明一些分数边界值

     //level提升所需的分数
     enum LevelUp_Score
     {
         Level1Up_Score = ,
         Level2Up_Score = ,
         Level3Up_Score = ,
         Level4Up_Score =
     };

　　

2.在移动的Baby对象类的.cpp文件的update方法中写，每一帧都会执行update方法

　　

 //让生成的Baby实例对象不断地往左边移动，超出屏幕就消失，好像有了这个就不用再在Block和Star的定义下面写一个用来消失的update函数了
 void Baby::update(float dt){
     //log("wo zai baby update limian1");
     m_score=GameScene::sharedGameLayer()->getScore();
     //log("wo zai baby update limian2");
     //m_score=GameScene::getScore();
     //根据到达的分数，设置LEVEL
     if (m_score > GameScene::LevelUp_Score::Level1Up_Score && m_score < GameScene::LevelUp_Score::Level2Up_Score)
     {
         //m_level = LEVEL2;
         setPositionX(getPositionX() - );
     }
     else if (m_score > GameScene::LevelUp_Score::Level2Up_Score && m_score < GameScene::LevelUp_Score::Level3Up_Score)
     {
         //m_level = LEVEL3;
         setPositionX(getPositionX() - );
     }
     else if (m_score > GameScene::LevelUp_Score::Level3Up_Score && m_score < GameScene::LevelUp_Score::Level4Up_Score)
     {
         //m_level = LEVEL4;
         setPositionX(getPositionX() - );
     }
     else if (m_score > GameScene::LevelUp_Score::Level4Up_Score)
     {
         //m_level = LEVEL5;
         setPositionX(getPositionX() - );
     }
     else
     {
         setPositionX(getPositionX() - );
         //setPositionX(getPositionX() - 6);
     }

     if (getPositionX()<-this->getContentSize().width) {
             unscheduleUpdate();
             removeFromParent();
         }
 }
