tolua杂记

1 字符串调用luaFunc  :DoString

 

public class CallLuaFunction : MonoBehaviour 
{
    private string script =
        @"  function luaFunc(num)                        
                return num + 1
            end

            test = {}
            test.luaFunc = luaFunc
        ";

    LuaFunction luaFunc = null;
    LuaState lua = null;
    string tips = null;
    
    void Start () 
    {
        new LuaResLoader();
        lua = new LuaState();
        lua.Start();
        DelegateFactory.Init();        
        lua.DoString(script);

        //Get the function object
        luaFunc = lua.GetFunction("test.luaFunc");

        if (luaFunc != null)
        {
            int num = luaFunc.Invoke<int, int>(123456);
            Debugger.Log("generic call return: {0}", num);

            num = CallFunc();
            Debugger.Log("expansion call return: {0}", num);

            Func<int, int> Func = luaFunc.ToDelegate<Func<int, int>>();
            num = Func(123456);
            Debugger.Log("Delegate call return: {0}", num);
            
            num = lua.Invoke<int, int>("test.luaFunc", 123456, true);
            Debugger.Log("luastate call return: {0}", num);
        }

        lua.CheckTop();
    }
    void OnDestroy()
    {
        if (luaFunc != null)
        {
            luaFunc.Dispose();
            luaFunc = null;
        }
        lua.Dispose();
        lua = null;
    }

    int CallFunc()
    {        
        luaFunc.BeginPCall();                
        luaFunc.Push(123456);
        luaFunc.PCall();        
        int num = (int)luaFunc.CheckNumber();
        luaFunc.EndPCall();
        return num;  
    }
}

2 执行lua文件

lua = new LuaState();                
        lua.Start();        
        //如果移动了ToLua目录，自己手动修复吧，只是例子就不做配置了
        string fullPath = Application.dataPath + "\\LuaFramework/ToLua/Examples/02_ScriptsFromFile";
        lua.AddSearchPath(fullPath);   
lua.DoFile("ScriptsFromFile.lua");     
//lua.Require("ScriptsFromFile");    Require 只执行一次                 
lua.Collect();
lua.CheckTop();
