篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了unity 导出ui初始化代码相关的知识，希望对你有一定的参考价值。
项目ui代码初始化部分 一般都可以自动生成。
原因：主要是手动填写ui node节点的路径，费时间。
实现结果：借助于插件 QHierarchy ，添加点选控制，只导出自己想要的节点。如下图红框内打钩的component是要导出代码。
步骤：1.点选 2.选预制件 3.点击导出 4.结果(具体代码文件不贴出来，而且每个项目可能ui代码规则不同)
实现方式：
主要是两部分代码：1.编辑器下 QHierarchy 代码插入 2.导出lua文件的代码
1.插入到QHierarchy
仿照QLockComponent.cs的流程，新加QToLuaUIComponent.cs类。此类是每个GameObject节点的显示和操作

"Choose" : "UnChoose"); 180 181 for (int i = gameObjects.Count - 1; i >= 0; i--) 182 { 183 GameObject curGameObject = gameObjects[i]; 184 Undo.RecordObject(curGameObject, targetLock ? "Choose" : "UnChoose"); 185 186 if (targetLock) 187 { 188 189 if (!objectList.chooseObjects.Contains(curGameObject)) 190 objectList.chooseObjects.Add(curGameObject); 191 } 192 else 193 { 194 195 objectList.chooseObjects.Remove(curGameObject); 196 } 197 198 EditorUtility.SetDirty(curGameObject); 199 } 200 } 201 202 203 } 204 }
QObjectList内加一行
public GameObject selectPrefab = null; 用来获取预制件
QObjectListInspector内添加，用于Inspector界面的显示交互：
1 EditorGUILayout.HelpBox("export ui script", MessageType.Info, true); 2 if (GUI.Button(EditorGUILayout.GetControlRect(GUILayout.ExpandWidth(true), GUILayout.Height(20)), "ExportLuaUIScript")) 3 { 4 foreach (QObjectList objectList in QObjectList.instances) 5 { 6 GameObject prefabObj = objectList.selectPrefab; 7 QExportUIScript.BeginExport(prefabObj); 8 } 9 }
QHierarchySettingsWindow.cs内控制 setting面板 是否开启新加的功能：
1 // -- toLuaUI-- 2 drawSeparator(); 3 drawToLuaUISetting(); 4 // -----------
QSettings内添加 ToLuaUI = 100, public const string DEFAULT_ORDER = "0;1;2;3;4;5;6;7;8;9;10;11;12;13";
还有其他的零碎，不想写了。
2.导出lua文件的代码
新建QExportUIScript.cs类：实现初始化 ui prefab的功能和针对 button组件生成 按钮相应接口
