Quick Cocos2dx 初步战斗

呵呵，图片先来一发：

最近懒，很懒，连我自己都觉得有点可耻了。

但是实在没有什么东西啊，温水煮青蛙的什么的。

吐槽完成，以上。

目前完成了简单的战斗部分，AI还需要抽出来。

然后突然之间想到手游的帧频是60fps/s，然后就放弃了之前比较平滑的CCMoveTo，换成了每帧去计算坐标。

还增加了掉血计算与表现，与死亡逻辑处理。

虽然处理得不是很干净，但是这个是后续需要优化的部分。

本次的主要用到的知识点：

framework.scheduler

framework.transition

写这篇blog的目的是在于给自己一点动力，能够一步一个脚印去记录自己。

主要更新的代码部分：

GameUnit.lua:增加了死亡逻辑处理
