自己用 love2d 做游戏，开了好几个头，最后都因为种种原因不了了之。。其中最最重要的原因之一，就是没有现成的图。
网上找到的图，经常是大章的，整合过的。自己在用起来的时候，就得自己拿着 photoshop 去量 每个小土块的 uv坐标，量好了手写到 lua 文件里。
为了快速出原形的时候，这不失为一种便捷的做法，但是每次自己去量的时候也很头疼。这时候就希望能有个工具，能自动给我量好了，然而这并不可能。。最多也就是可视化丈量了。于是想，干脆自己开发这么个工具得了（话说N多年前自己就有过这样的想法)。但是这样搞成本太高了，自己也没这个心思。于是怀念起来刚刚入职 gl 时，用的 AuroraGT.里面的 Sprite 编辑器其实就是一个可视化编辑的工具，非常符合我的需求。
3，4年前上班的时候，自己搞过用 c++解析 AuroraGT 导出的 .sprite 文件，并且用 dx 渲染出来的小东西。那个时候我的做法，竟然是直接在主程序里，读取并解析 .sprite 文件。。而且写得效率并不高，分析一个大点的 .sprite 文件速度慢的要死。现在用 love2d, 打算直接把 .sprite 文件直接导成 .lua 代码。这个思路的主要来源有两个：1年前看cocosstudio ，记得有个功能是能直接根据 排版的 menu 布局，导出成 lua 代码；现在上班的公司，也是直接把 配置文件 csv 搞成 lua 代码的。这样 在 love2d 的游戏主程序里用起来，就省略了解析这一步，用起来 效率肯定会高出不少。
AuroraGT 这个软件，能够把图片，根据 uv 坐标，拆成许许多多的小块，称为 module。 一般我想象中的拆图工具，功能到此也就结束了;然而 AuroraGT 牛的地方在于，还可以自行拼装 这些 module ,组成 几个 module 合成的一个图块，成为 frame;到这里当然还没结束，还能把这些 frame 按照顺序，组成 animation
也就是说，AuroraGT 不是一个简单的拆图片软件，还能做帧动画编辑器，图片如果拆的够细致，图片的利用率就非常高，能在很省图片的情况下，完整保存帧动画数据。当然你也可以把 module 和 frame 视为 1对1 的，简单的把这个东西当成一个普通的帧动画编辑器也可以。
为了简单，我做的这个导出，只支持 一个.sprite 文件，对应一张图片。 我认为这样足够了， 对应多张实在有点乱。
下面3段分别是 AuroraGT 导出的 .sprite 文件, python 导出代码, lua 导出结果。
为了速度实现功能，代码没往美观的写，留在这里做个备忘

AuroraGT 除了 sprite 编辑器外，还有个 Game编辑器，和 Map 编辑器的功能。
这两个编辑器我还不太明白具体的用法。将来了解一下，如果好用的话，我会再搞相应的 python脚本 去导出这两种工具的 结果文件。
记录结束，赶紧睡了。
