最近在研究大大的代码，斜45度地图的渲染这里看的有些头晕。不明白坐标都是如何计算的，还有resource/earth.002里的索引和index.ka里的坐标分别都是什么的索引啊。 |

来自问自答吧，earth.002这些文件里的是素材的索引。理论上来讲，靠这里的索引已经能计算出素材的坐标 |

所有图片的零点定义到下面中间 例如人 建筑等 方便判断物件的地点坐标 |

p.x = -y * TILE_W + x * TILE_W + render_center_x_; p.y = y * TILE_H + x * TILE_H + render_center_y_;但是这些素材不知道为什么还有一定的坐标偏移，存在index.ka里，真正的显示坐标要用计算出来的坐标减去偏移坐标
