Lua和C#互調的一個簡單案例

XLua和C#互調的一個簡單案例

用Lua寫了一個點擊旋轉的方法,可以先把這三個腳本拖進去看看效果。
C#腳本如下:
1.一個Lua虛擬機單例：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using XLua;
/// <summary>
/// Lua虛擬機單例模板
/// </summary>
public class LuaSimulator : MonoBehaviour
{
    internal static float lastGcTime = 0;
    public const float gcInterval = 1;//釋放內存的間隔時間
    static LuaEnv myLuaEnv;
    public static LuaEnv MyLuaEnv
    {
        get
        {
            if (myLuaEnv == null)
            {
                myLuaEnv = new LuaEnv();
            }
            return myLuaEnv;
        }
    }
    void Update()
    {
        if (Time.time - lastGcTime > gcInterval)
        {
            myLuaEnv.Tick();
            lastGcTime = Time.time;
        }
    }
}

2.CSCallLua

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using XLua;
using System;
public class MBehaviour : MonoBehaviour {

    public TextAsset luaScript;
    private Action luaAwake;
    private Action luaStart;
    private Action luaUpdate;
    private Action<Collider> luaOnTriggerEnter;
    private Action luaOnDestroy;
    private LuaTable scriptEnv;
    void Awake()
    {
        scriptEnv = LuaSimulator.MyLuaEnv.NewTable();
        // 爲每個腳本設置一個獨立的環境，可一定程度上防止腳本間全局變量、函數衝突
        LuaTable meta = LuaSimulator.MyLuaEnv.NewTable();
        meta.Set("__index", LuaSimulator.MyLuaEnv.Global);
        scriptEnv.SetMetaTable(meta);
        meta.Dispose();

        scriptEnv.Set("self", this);
        LuaSimulator.MyLuaEnv.DoString(luaScript.text,"ChunkName",scriptEnv);//ChunkName是什麼無所謂
        scriptEnv.Get("Awake", out luaAwake);
        scriptEnv.Get("Start", out luaStart);
        scriptEnv.Get("Update", out luaUpdate);
        scriptEnv.Get("OnTriggerEnter", out luaOnTriggerEnter);
        scriptEnv.Get("OnDestroy", out luaOnDestroy);

        if (luaAwake != null)
        {
            luaAwake();
        }
        DontDestroyOnLoad(gameObject);
    }
    void Start () {
        if (luaStart != null)
        {
            luaStart();                                 
        }
	}
	
	// Update is called once per frame
	void Update () {
        if (luaUpdate != null)
        {
            luaUpdate();
        }
	}
    void OnTriggerEnter(Collider other)
    {
        if (luaOnTriggerEnter != null)
        {
            luaOnTriggerEnter(other);
        }
    }
    void OnDestroy()
    {
        if (luaOnDestroy != null)
        {
            luaOnDestroy();
        }
        luaOnDestroy = null;
        luaUpdate = null;
        luaStart = null;
        luaAwake = null;
        scriptEnv.Dispose();
    }
}

3.LuaCallCS對應的Lua腳本如下,文件後綴名爲.lua.txt或者.txt,但是不能爲.lua,Unity不能直接識別.lua後綴名的文件,一般習慣性後綴名都使用.lua.txt，以便於區分腳本文件類型，腳本名字的話隨便起。

Debug = CS.UnityEngine.Debug
Input = CS.UnityEngine.Input
GameObject = CS.UnityEngine.GameObject
Vector3 = CS.UnityEngine.Vector3
function Awake()
    Debug.Log("你好,我是Lua的Awake方法")
end
function Start()
     Debug.Log("你好,我是Lua的Start方法")
end
function Update()
    --Debug.Log("你好,我是Lua的Update方法")
    GameObjectRotate()
end
function OnDestroy()
    Debug.Log("你好,我是Lua的OnDestroy方法")
end
function GameObjectRotate()

    if (Input.GetMouseButton(0)) then
        GameObject.Find("Cube").transform:Rotate(Vector3.up, 30);
        Debug.Log("你好,我是Lua的GameObjectRotate方法")
    end
end
