using System.Collections; using UnityEditor.ProjectWindowCallback; using System.IO; using UnityEditor; public class CreateLua {[MenuItem(Assets/Create/Lua Script,false,80)] //80是菜单的次序public static void CreateNewLua(){ProjectWindowUtil.StartNameEditingIfProjectWindowExists(0,ScriptableObject.CreateInstanceCreateScriptAssetAction(),GetSelectedPathOrFallback() /New Lua.lua,null,Assets/Editor/Template/LuaComponent.lua);}public static string GetSelectedPathOrFallback(){string path Assets;foreach (UnityEngine.Object obj in Selection.GetFiltered(typeof(UnityEngine.Object), SelectionMode.Assets)){path AssetDatabase.GetAssetPath(obj);if (!string.IsNullOrEmpty(path) File.Exists(path)){path Path.GetDirectoryName(path);break;}}return path;} } class CreateScriptAssetAction:EndNameEditAction {public override void Action(int instanceId, string pathName, string resourceFile){//创建资源UnityEngine.Object obj CreateAssetFromTemplate(pathName, resourceFile);//高亮显示该资源ProjectWindowUtil.ShowCreatedAsset(obj);}internal static UnityEngine.Object CreateAssetFromTemplate(string pahtName, string resourceFile){//获取要创建的资源的绝对路径string fullName Path.GetFullPath(pahtName);//读取本地模板文件StreamReader reader new StreamReader(resourceFile);string content reader.ReadToEnd();reader.Close();//获取资源的文件名// string fileName Path.GetFileNameWithoutExtension(pahtName);//替换默认的文件名content content.Replace(#TIME, System.DateTime.Now.ToString(yyyy年MM月dd日 HH:mm:ss dddd));//写入新文件StreamWriter writer new StreamWriter(fullName, false, new System.Text.UTF8Encoding(false));writer.Write(content);writer.Close();//刷新本地资源AssetDatabase.ImportAsset(pahtName);AssetDatabase.Refresh();return AssetDatabase.LoadAssetAtPath(pahtName, typeof(UnityEngine.Object));} }在Editor目录下创建Template文件夹存放模板里面的文件如下 local LuaBehaviour require(Component.LuaBehaviour) local newclass LuaExtend(LuaBehaviour)function newclass:Awake() end function newclass:Update() endreturn newclass 这样在右键菜单Create中就会多出一个Lua Script的选项可以直接创建Lua的模板文件。 Lua调用Unity相关组件和接口 Unity编辑器相关CS.UnityEngine例如CS.UnityEngine.Time.deltaTime 自己定义的类CS.命名空间.类名 为了方便我们可以在lua中重新进行定义 local Time CS.UnityEngine.Time另外在上面组件化开发模式中我们可以直接才lua模块中使用obj.gameObject,obj.transform来获取对应物体和对应物体的transform的信息。 C#端创建一个脚本 using UnityEngine;
