以上问题如下步骤解决
在导入的 这个插件 的文件夹中，打开示例 场景，在 Hierarchy视图 ，找到 Camera 物体，打开 GUI Controller，如下图所示
在GUI Controller 中有两种解决办法，
第1种，在Start函数上面 添加 一个 private Camera camera;并在Start函数里面为 这个 camera 进行初始化。（这个 GUIController.cs 就得在 Camera物体上有效）
如下图所示
第2种方式，添加public Camera camera;，设置为公共成员 如下图所示
设置了公共成员之后，把Camera物体 拖入 该变量即可。
记得选择 字体
效果如下图所示
