}
GetIrrlichtManager()->GetDevice()->getTimer()->setTime(0);

video::IVideoDriver* driver = GetIrrlichtManager()->GetDriver();
scene::ISceneManager* smgr = GetIrrlichtManager()->GetScene();
IrrlichtDevice * device = GetIrrlichtManager()->GetDevice();

video::ITexture* imgBack;

imgBack = driver->getTexture("interface/map.rttex");
driver->makeColorKeyTexture(imgBack, core:osition2d<s32>(0,0));

driver->getMaterial2D().TextureLayer[0].BilinearFilter=true;
driver->getMaterial2D().AntiAliasing=video::EAAM_FULL_BAS IC;

driver->draw2DImage(imgBack, core:osition2d<s32>(50,50),
core::rect<s32>(0,0,342,224), 0,
video::SColor(255,255,255,255), true);
