通过Lua代码创建一个Cube,并实现控制行走

//创建一个Cube
GameObject = UnityEngine.GameObject
Input = UnityEngine.Input
Time = UnityEngine.Time
Transform = UnityEngine.Transform
Rigidbody = UnityEngine.Rigidbody

cube = nil
transform = nil
rig = nil

function OnStart()
    cube = GameObject.Instantiate(prefab)
    rig = cube:AddComponent(typeof(Rigidbody))
    rig.useGravity = false
    transform = cube:GetComponent(typeof(Transform))
    transform.position = Vector3(0,1,-5)
end

function OnUpdate()
    x,y = 0,0
    x = Input.GetAxis("Horizontal")
    y = Input.GetAxis("Vertical")
    transform:Rotate(Vector3(0,x,0)*Time.deltaTime*100)
    transform.position = transform.position + transform.forward*y*Time.deltaTime*10
end

将脚本写好后拖到Unity中

在C#脚本中
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using LuaInterface ;

public class CreatCubeByLuaScr : MonoBehaviour {

    public TextAsset luaTex;
    LuaState  luaState;
    public GameObject cube;
    //定义一个lua函数字段
    LuaFunction StarFunc;

    void Start () {
        luaState = new LuaState ();
        luaState.Start ();
        LuaBinder.Bind (luaState);
        //给lua文件中使用的预设体赋值
        luaState ["prefab"] = cube;
        luaState.DoString (luaTex.text);
        //获取lua代码中的方法
        StarFunc = luaState.GetFunction ("OnStart");
        //调用Lua中的代码执行
        StarFunc.Call ();

    }

    void Update () {
        UpdateFunc.Call ();
    }
}

挂上c#脚本：将lua文件拖到Lua Text中
