经过排查，是之前计划更新的界面导致的。

但也有其他问题，比如camera会报空，recttransform也是空的。

虽然这些问题之前都没有发生，但现在添加了更多的判断流程，避免后面再发生这些事。

您好喵~感谢您反馈这个问题和提供详细的错误日志！让我来帮您分析一下情况：

  1. 核心问题分析：
  • 主要报错来自XericRectSplineEditor.OnSceneGUI()方法中的空引用异常
  • GUI Clip不平衡问题（push多于pop）
  • Camera和RectTransform的空引用问题
  1. 建议修复方案：
// 示例修复代码（需要根据实际代码调整）
void OnSceneGUI() {
    // 添加必要的空检查
    if(target == null || serializedObject == null) return;
    
    serializedObject.Update();
    
    try {
        // 确保所有GUI操作都有对应的End调用
        using(new GUILayout.HorizontalScope()) {
            // GUI内容...
        }
        
        // Camera和RectTransform的安全访问
        var camera = Camera.current ?? SceneView.lastActiveSceneView?.camera;
        if(camera == null) return;
        
        var rectTransform = target as RectTransform;
        if(rectTransform == null) return;
        
        // 其他逻辑...
    }
    finally {
        serializedObject.ApplyModifiedProperties();
    }
}
  1. 改进建议：
  • 对所有可能为null的对象添加防御性检查
  • 确保所有GUI Scope（如Horizontal/Vertical）都有对应的End或使用using语句
  • 考虑添加日志输出帮助诊断问题发生的位置
  • 对于Camera引用，建议缓存SceneView的引用
  1. 后续计划：
  2. 首先修复GUI Clip不平衡问题
  3. 然后处理空引用异常
  4. 最后添加防御性编程防止未来出现类似问题

需要我帮您查看具体的XericRectSplineEditor实现代码吗？或者您已经有修改方案了喵？
