unity3d性能优化（tolua篇）_skybeauty_新浪博客

tolua篇：

我们目前开发采用的是tolua，大家可能都知道c#到lua是需要导出接口给lua调用的，只要lua获取unity的对象，那么tolua都会根据id（唯一）保存在 LuaState中的 ObjectTranslator 中，每个lua变量都是唯一对应的，参考图

#define MISS_WARNING

using System;

using System.IO;

using System.Collections;

using System.Collections.Generic;

using System.Collections.ObjectModel;

using System.Runtime.InteropServices;

using System.Runtime.CompilerServices;

using System.Text;

using UnityEngine;

namespace LuaInterface

{

    public class LuaState : LuaStatePtr, IDisposable

    {

        public ObjectTranslator translator = new ObjectTranslator();

        public LuaReflection reflection = new LuaReflection();

        public int ArrayMetatable { get; private set; }

        public int DelegateMetatable { get; private set; }

        public int TypeMetatable { get; private set; }

        public int EnumMetatable { get; private set; }

        public int IterMetatable { get; private set; }        

        public int EventMetatable { get; private set; }

        //function ref                

        public int PackBounds { get; private set; }

        public int UnpackBounds { get; private set; }

        public int PackRay { get; private set; }

        public int UnpackRay { get; private set; }

        public int PackRaycastHit { get; private set; }        

        public int PackTouch { get; private set; }

具体可以参考tolua中的类ObjectTranslator.cs,

using System;

using System.Collections.Generic;

using System.Runtime.CompilerServices;

using UnityEngine;

namespace LuaInterface

{

    public class ObjectTranslator

    {        

        private class DelayGC

        {

            public DelayGC(int id, UnityEngine.Object obj, float time)

            {

                this.id = id;

                this.time = time;

                this.obj = obj;

            }

            public int id;

            public UnityEngine.Object obj;

            public float time;

        }

        private class CompareObject : IEqualityComparer

        {

            public new bool Equals(object x, object y)

            {

                return object.ReferenceEquals(x, y);                

            }

            public int GetHashCode(object obj)

            {

                return RuntimeHelpers.GetHashCode(obj);                

            }

        }

        public bool LogGC { get; set; }

        public readonly Dictionary objectsBackMap = new Dictionary (new CompareObject());

        public readonly LuaObjectPool objects = new LuaObjectPool();

        private List gcList = new List();
