关于自己学习xlua的一些心得

直接举个例子
首先直接在场景里边新建一个LuaMgr的空物体
然后挂上一个脚本using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using XLua;
using System.IO;

public class HotFixScript : MonoBehaviour
{
private LuaEnv lua;
// Start is called before the first frame update
void Awake()
{
lua = new LuaEnv();
lua.AddLoader(MyLoader);
lua.DoString(@“require ‘game’”);
}

private byte[] MyLoader(ref string fileluaname)
{
    string absPath = Application.dataPath+@"\LuaText\" + fileluaname + ".lua";
    Debug.Log("abspath"+absPath);

    return System.Text.Encoding.UTF8.GetBytes(File.ReadAllText(absPath));
}
// Update is called once per frame
private void OnDestroy()
{
    lua.Dispose();
}

private void OnDisable()
{
    lua.DoString(@"require 'gameDispose'");
}

}
game.lua和gameDispose.lua脚本如下

 GameObject=CS.UnityEngine.GameObject
 Input=CS.UnityEngine.Input

 PlayerMove=CS.PlayerMove
 Vector3 =CS.UnityEngine.Vector3
 Time=CS.UnityEngine.Time

 Quaternion=CS.UnityEngine.Quaternion
 Destroy=CS.UnityEngine.GameObject.Destroy


--LUA实现人物移动
xlua.private_accessible(PlayerMove)

xlua.hotfix(PlayerMove,'Update',function(self)
         -- local moveSpeed= self.moveSpeed
          --local rotateSpeed=self.rotateSpeed
        -- print('Time'..Time.deltaTime)
       --  print('moveSpeed'..':'..self.moveSpeed)
       --  print('rotateSpeed'..':'..self.rotateSpeed)
       --  print('vinput'..self.vInput)
        -- print('hInput'..self.hInput)
        
     
         self.vInput=Input.GetAxis('Vertical') * (self.moveSpeed)
         self.hInput=Input.GetAxis('Horizontal') * (self.rotateSpeed)
     
         --self.transform:Translate(Vector3.forward * self.moveSpeed * self.vInput * Time.deltaTime)
        -- self.transform:Rotate(Vector3.up * self.hInput * self.rotateSpeed * Time.deltaTime)
end)

xlua.hotfix(PlayerMove,'Start',function (self)

    self.Rigidbody=self.transform:GetComponent('Rigidbody')
    
end)

xlua.hotfix(PlayerMove,'FixedUpdate',function (self)
    
    local rotation=Vector3.up*self.hInput

    local angleRot=Quaternion.Euler(rotation* Time.fixedDeltaTime)

    self.Rigidbody:MovePosition(self.transform.position+self.transform.forward*self.vInput* Time.fixedDeltaTime)

    self.Rigidbody:MoveRotation(self.Rigidbody.rotation*angleRot);

end)


--实现人物摄像机跟随
CameraMove=CS.CameraMove

xlua.private_accessible(CameraMove)
xlua.hotfix(CameraMove,'Start',function (self)

    self.camoffset=Vector3(0,1.2,-2.6)
   
    self.target=GameObject.Find('Player').transform
    
    print("cam开始执行")

    
end)

xlua.hotfix(CameraMove,'LateUpdate',function (self)

    self.transform.position=self.target.TransformPoint(self.target,self.camoffset)

    self.transform:LookAt(self.target)
    
end)

--物体被捡起来的脚本
ItemScript=CS.ItemScript
xlua.private_accessible(ItemScript)
xlua.hotfix(ItemScript,'OnCollisionEnter',function (self,collision)
    
    print("hello")
    if collision.gameObject.name=='Player' then
        Destroy(self.gameObject)
        print('luaItemPicked')
    end

end)

--敌人发现自己的脚本
EnemyScript=CS.EnemyScript
xlua.private_accessible(EnemyScript)
xlua.hotfix(EnemyScript,'OnTriggerEnter',function(self, collider)
       if collider.name=='Player' then
           print("lua敌人发现了自己")
       end
end)
xlua.hotfix(EnemyScript,'OnTriggerExit',function(self,collider)
       if collider.name=='Player' then
           print("lua我已经走出敌人范围之外了")
       end
end)

gameDispose.lua脚本如下

PlayerMove=CS.PlayerMove
xlua.hotfix(PlayerMove,'Update',nil)
xlua.hotfix(PlayerMove,'Start',nil)
xlua.hotfix(PlayerMove,'FixedUpdate',nil)
CameraMove=CS.CameraMove
xlua.hotfix(CameraMove,'Start',nil)
xlua.hotfix(CameraMove,'LateUpdate',nil)
ItemScript=CS.ItemScript
xlua.hotfix(ItemScript,'OnCollisionEnter',nil)
EnemyScript=CS.EnemyScript
xlua.hotfix(EnemyScript,'OnTriggerEnter',nil)
xlua.hotfix(EnemyScript,'OnTriggerExit',nil)

然后上边对应的PlayerMove，CameraMove,ItemScript分别对应继承mono的脚本
在这里插入图片描述
实际上lua并不是很难，最主要用好table,metatable之间的区别 .和：之间的区别
