[aktlakfh1777]

what can i do ?

Code: Select all

class gameFrames:public IEventReceiver
{
private:
	DataBank *db;
	IVideoDriver* _driver;
	ISceneManager* _smgr;
	IGUIEnvironment* _guienv;
	IrrlichtDevice* _device;
	IGUISkin* skin;
	IGUIFont* font;
	framesWork *fw;
	GuiManagement *guiman;
	IEventReceiver *_eru_;
	int nfGameLevel;
	int nowFrame;
	int nLoginWork;
	bool loadedComplete;
public:
	graphic_ARGBUnit *gfARGB;
	void valueInit()
	{
		this->fw=new framesWork();
		this->nowFrame=0;
		this->loadedComplete=false;
		this->db=new DataBank();
		this->nfGameLevel=0;
		this->nLoginWork=0;
		this->skin = _guienv->getSkin();
		this->font = _guienv->getFont("datas/font.bmp");
		if (this->font)
			this->skin->setFont(this->font);
		this->skin->setFont(_guienv->getBuiltInFont(), EGDF_TOOLTIP);
		this->guiman=new GuiManagement(_guienv);
	}
	gameFrames(IVideoDriver *_drv,ISceneManager *_smr,IGUIEnvironment *_gui,IrrlichtDevice *_irrDev)
	{
		this->_driver=_drv;
		this->_smgr=_smr;
		this->_device=_irrDev;
		this->_guienv=_device->getGUIEnvironment();
		this->valueInit();
	}
	gameFrames(IVideoDriver *_drv,ISceneManager *_smr,IGUIEnvironment *_gui,IrrlichtDevice *_irrDev,graphic_ARGBUnit *argbunit)
	{
		this->_driver=_drv;
		this->_smgr=_smr;
		this->_guienv=_gui;
		this->_device=_irrDev;
		this->_guienv=_device->getGUIEnvironment();
		this->gfARGB=argbunit;
		this->valueInit();
	}
	void steping(); // game loop
	void loopwork()
	{
		// Draw And Scene Line
		this->_driver->beginScene(true, true, SColor(this->gfARGB->getAlpha(),this->gfARGB->getRed(),this->gfARGB->getGreen(),this->gfARGB->getBlue()));
		this->_smgr->drawAll();
		this->_guienv->drawAll();
		this->fw->ppFrame();
	}
	void finalwork()
	{
		this->_driver->endScene();
	}
	void loginWork()
	{
		_driver->draw2DImage(_driver->getTexture("datas/login_screen.jpg"),core::position2d<s32>(0,0));
		if(nLoginWork==0)
		{
			IGUIButton *lgin=this->_guienv->addButton(rect<s32>(300,300,110,100),0,GUI_BUTTON_LOGINLEVEL_LOGINOK,L"Login",L"Login Now.");
			lgin->draw();
			nLoginWork++;
		}else{
		}
	}
	bool OnEvent(const SEvent &event);
};

It doesn't work !
it could be compiled well(with no error).
but, button is not displayed on screen.
how to fix my code ?

[Eigen]

It's not displayed, because your button dimensions are off.

Correct usage would be

Code: Select all

rect<s32>(x1, y1, x2, y2)

not

Code: Select all

rect<s32>(x, y, width, height)

Use

rect<s32>(300,300,410,400) instead.

thanks for your advice, but it still does not work.

1.make sure that nLoginWork==0 (or else it wont show the button offcourse)
2.try changing the add button position to something like this

Code: Select all

addButton(rect<s32>(10,240,110,240)

and see if the button displays...if not then your code is being misunderstanded by the compiler somewhere else in your code.
