导出unity场景的所有游戏对象信息,一种是XML一种是JSON。本篇文章我们把游戏场景中游戏对象的、旋转、缩放、平移与Prefab的名称导出在XML与JSON中。然后解析刚刚导出的XML或JSON通过脚本把导出的游戏场景还原。在Unity官网上下载随便下载一个demo Project,如下图所示这是我刚刚在官网上下载的一个范例程序。
接着将层次视图中的所有游戏对象都封装成Prefab保存在资源路径中,这里注意一下如果你的Prefab绑定的脚本中有public Object 的话 ,需要在代码中改一下。。用 Find() FindTag()这类方法在脚本中Awake()方法中来拿,不然Prefab动态加载的时候无法赋值的,如下图所示,我把封装的Prefab对象都放在了Resources/Prefab文件夹下。
OK,现在我们就需要编写我们的导出工具、在Project视图中创建Editor文件夹,接着创建脚本MyEditor 。如下图所示。
因为编辑的游戏场景数量比较多,导出的时候我们需要遍历所有的游戏场景,一个一个的读取场景信息。然后取得游戏场景中所有游戏对象的Prefab的 名称 旋转 缩放 平移。有关XML的使用请大家看我的上一篇文章: unity3d研究院之使用 C#合成解析XML与JSON(四十一) 代码中我只注释重点的部分,嘿嘿。
