Unity Editor includeChildren为false时无法单独控制子Toggle问题

问题原因 #

现有渲染逻辑在OnGUI每帧执行时，都会无条件将单物体对应的include1数组值强制覆盖为和全局includeChildren变量一致，不管全局开关有没有被用户修改。这就导致全局开关为false时，用户手动点击单个Toggle修改的状态，会在下一帧渲染时被直接重置为false，完全无法手动调整单个物体的设置。

修复方案 #

• 只在用户主动操作修改全局includeChildren开关的瞬间，才批量同步所有单个物体的Toggle值，全局开关状态不变时，不强制覆盖单个Toggle的用户设置
• 全局开关为true时，将单个Toggle设为禁用状态，避免和全局全选逻辑冲突；全局开关为false时，解锁单个Toggle的编辑权限，支持用户手动勾选
• 补全选中物体变化时的数组初始化逻辑，避免选中物体数量变化后出现数组索引越界异常

核心代码修改 #

1. 全局开关增加变化检测 #

替换原有全局Toggle渲染代码：

// 检测全局开关是否被用户主动修改
EditorGUI.BeginChangeCheck();
includeChildren = EditorGUILayout.Toggle("Include Children", includeChildren);
bool globalToggleChanged = EditorGUI.EndChangeCheck();

2. 替换循环内的单个Toggle逻辑 #

删除原有强制赋值的if/else代码块，替换为以下逻辑：

// 仅全局开关刚被修改时，才同步所有单个Toggle状态
if (globalToggleChanged)
{
    include1[i] = includeChildren;
}
// 全局开启时禁用单个Toggle编辑，全局关闭时允许手动调整
using (new EditorGUI.DisabledScope(includeChildren))
{
    include1[i] = EditorGUILayout.Toggle("Include Children", include1[i], GUILayout.ExpandWidth(true));
}

3. 补全选中物体变化时的数组初始化 #

修改OnSelectionChange方法，避免数组长度不匹配：

private void OnSelectionChange()
{
    objects = Selection.gameObjects;
    // 重新初始化单个Toggle数组，长度和当前选中物体匹配
    include1 = new bool[objects.Length];
    // 全局开关为开启状态时，所有单个Toggle默认设为true
    if (includeChildren)
    {
        for (int i = 0; i < include1.Length; i++)
        {
            include1[i] = true;
        }
    }
}

        if (Event.current.type == EventType.MouseUp && foldRect.Contains(Event.current.mousePosition))

                    objects[i] = (GameObject)EditorGUILayout.ObjectField(i.ToString(), objects[i], typeof(GameObject), true, options);
                    EditorGUIUtility.labelWidth = 112;
                    
                    if (globalToggleChanged)
                    {
                        include1[i] = includeChildren;
                    }

                    using (new EditorGUI.DisabledScope(includeChildren))

                        include1[i] = EditorGUILayout.Toggle("Include Children", include1[i], GUILayout.ExpandWidth(true));
                    }
                }
                EditorGUILayout.EndHorizontal();

            EditorGUILayout.EndScrollView();

            EditorGUI.indentLevel--;
        }

        GUILayout.FlexibleSpace();
        if (GUILayout.Button("Rename Objects"))
        {
            // 后续重命名逻辑可在此处实现，遍历objects时根据include1[i]判断是否获取子物体即可
        }

        Repaint();
    }
}

实现效果验证 #

• 全局includeChildren勾选时：所有单个物体的子物体Toggle自动全选且置灰不可编辑，符合全局全选的预期
• 全局includeChildren取消勾选时：单个Toggle恢复可编辑状态，用户可以自由勾选需要处理子物体的条目，不会被每帧强制重置
