VS build Lua development environment and Luabridge Register C + + class (COCOS2DX project) (ii)

In this article we register 2 classes to test the use of the Luabridge, before we begin, we use C + + to invoke the LUA function on the basis of the previous article. We add a Main.lua file to the resource folder. The LUA code is as follows:

1 function Init () 2     Print (1) 3 End

Then, add the following code in the Initscript () function:

1 std::string FilePath = Fileutils::getinstance ()->fullpathforfilename ("Main.lua "); 2     int ret = lual_dofile (m_luastate, Filepath.c_str ()); 3     if (! ret) 4     {5         runluafunc ("init"); 6     }

The Runluafunc function is as follows:

void Helloworld::runluafunc (std::string  funcName) {    new  luabridge::luaref (getglobal (M_luastate, Funcname.c_str ()));     Try     {        if (lua_func->isfunction ())        {            (*lua_func) ();        }    }     Catch (luaexception& e)    {        Cclog ("%s", E.what ());    }    }

OK, call success ...

The following adds a class, Uimanage class, for adding UI and registering control events ...

We move the initscript and Runluafunc functions into the Uimanage class. Modify the Initscript function as follows:

1 voidUimanage::initscript ()2 {3M_luastate =lual_newstate ();4 lual_openlibs (m_luastate);5 6 getglobalnamespace (m_luastate)7 8. Beginnamespace ("Game")9 Ten.beginclass<widget> ("Widgets") One. AddFunction ("Getchildbytag", &Widget::getchildbytag) A . Endclass () -  -.beginclass<uimanage> ("Uimanage") the. Addstaticfunction ("instance", &uimanage::getintance) -. AddFunction ("AddWidget", &uimanage::addwidget) - . Endclass () -  + . Endnamespace () -  +         ; A  atSTD::stringFilePath = Fileutils::getinstance ()->fullpathforfilename ("Main.lua"); -     intRET =lual_dofile (M_luastate, Filepath.c_str ()); -     if(!ret) -     { -Runluafunc ("Init"); -     } in     Else -     { toCclog ("Lua Error:%s", Lua_tostring (M_luastate,-1)); +     } -}

We register the getinstance and AddWidget functions into Lua, and then the Main.lua as follows:

Uimanage =function()    local PNL = Uimanage:addwidget ("  Loginui/loginui.exportjson")End

First get the Uimanage Singleton class, then call the function Addwidget,ok, find the interface successfully added.

Add: The calling code is as follows ...

void Helloworld::onenter () {    layer::onenter ();    Uimanage::getintance ()initscript ();}

The following adds events to the controls on the interface ....

Add the function as follows (void Addtoucheventlistener (Ccwidgettouchcallback callback)):

1 voidUimanage::addeventlisten (widget* UI, std::stringfuncName)2 {3STD::stringBeginname = FuncName +"_begin";4STD::stringMovename = FuncName +"_move";5STD::stringEndname = FuncName +"_end";6STD::stringCancelname = FuncName +"_cancel";7 8Auto Beginfunc =NewLuaref (Getglobal (M_luastate, Beginname.c_str ()));9Auto Movefunc =NewLuaref (Getglobal (M_luastate, Movename.c_str ()));TenAuto Endfunc =NewLuaref (Getglobal (M_luastate, Endname.c_str ())); OneAuto Cancelfunc =NewLuaref (Getglobal (M_luastate, Cancelname.c_str ())); A  -Ui->addtoucheventlistener ([Beginfunc, Movefunc, Endfunc, Cancelfunc] (ref*ref, Widget::toucheventtype type) -     { the         Switch(type) -         { -          CaseCocos2d::ui::widget::toucheventtype::began: -             if(beginfunc->isfunction ()) +             { -(*Beginfunc) (); +             } A              Break; at          Casecocos2d::ui::widget::toucheventtype::moved: -             if(movefunc->isfunction ()) -             { -(*Movefunc) (); -             } -              Break; in          Casecocos2d::ui::widget::toucheventtype::ended: -             if(endfunc->isfunction ()) to             { +(*Endfunc) (); -             } the              Break; *          Casecocos2d::ui::widget::toucheventtype::canceled: $             if(cancelfunc->isfunction ())Panax Notoginseng             { -(*Cancelfunc) (); the             } +              Break; A         } the     }); +}

Registering in Lua

1 . AddFunction ("addeventlisten", &uimanage::addeventlisten)

The LUA Code registration event is as follows:

1--Events2Clcickevent =3 {4Ends =function ()5Print1)6 End7 }8 9init =function ()TenLocal PNL = Uimanage:addwidget ("Loginui/loginui.exportjson") OneAddevent (pnl,clcickevent)--Add Event AUimanage:addeventlisten (PNL,"PNL") - End -  the  -  -Addevent = function (UI,Event) -_g["Pnlends"] =Event. Ends--Global Table C + +Direct access to pnlends calls in code event.ends +End

OK, event invocation succeeded
