cocos2d-x 3.0游戏开发xcode5帅印博客教学 004.[HoldTail]主角的上下飞行跟移动

写给大家的前言，在学习cocos2d-x的时候自己走了很多的弯路，也遇到了很多很多问题，不管是简单的还是困难的现在都慢慢的一步一步克服了，其实用cocos2d－x做游戏特别的简单，大家不要被是做游戏吓到了，支持我把游戏开源的原因是因为  eoe上海  的大家的支持。加油，加油，要说明一下的是，写得不好还请大家多多包含哦。相信你们跟着我得博客，一步一步做肯定会成功的。

看到有朋友跟这我做，感到很开心这样我才有写下去的信心，大家一起加油,主角写好了几天了一直没有更新，今天给大家更新送到，下次更新看到家的评论。

好了回到正题，今天开始主角的上下移动的控制

首先来添加主角类

    Sprite *fly = (Sprite *)this->getChildByTag(tag_player_fly);
    fly->setOpacity(0);
}

然后在游戏世界里面加入对主角的配置

当然对游戏的世界类也需要做小小的修改

        }
    }

        }
    }
}

好了这下，主角就可以上下移动了，原理就是控制背景的移动，从而达到主角的移动效果
