Font Draw - Sydney Tutorial

[WhyMe]

Hello.

I'm new on this forum and with programming with using graphics engines. So, i want to say hello to everyone, and please forgive me my english.

Ok.

I modify HelloWorld tutorial with drawing an extern fonts, but, even if they are loaded, they aren't displayed. I trying with built in fonts and this is the same.

Code:

Code: Select all

device->setWindowCaption(L"Hello World! - Irrlicht Engine Demo");
    IVideoDriver* driver = device->getVideoDriver();
    ISceneManager* smgr = device->getSceneManager();
    IGUIEnvironment* guienv = device->getGUIEnvironment();
 
   /*guienv->addStaticText(L"Hello World! This is the Irrlicht Software renderer!",
         rect<s32>(10,10,260,52), true);*/
 
    IGUIFont *nFont = guienv->getBuiltInFont(); /* guienv->getFont("myfont.xml");*/
 
    if(nFont) nFont->draw(L"Testuje sobie bal bla", core::rect<s32>(10,10,260,52), video::SColor(0,0,0,0));
 
    IAnimatedMesh* mesh = smgr->getMesh("sydney.md2");
        if (!mesh)
        {
            device->drop();
            return 1;
        }

Any advices ?

if(nFont) nFont->draw(L"Testuje sobie bal bla", core::rect<s32>(10,10,260,52), video::SColor(0,0,0,0));

Is that the only line where you do any drawing?
If so when your buffers get cleared (at beginScene?) and your text gets cleared from the screen. Or are you not using begin scene?

If so, use the draw function in main loop after buffers get cleared.

I moved this line to the loop, but it didn't work ...

Code: Select all

    QCoreApplication a(argc, argv);
    
    IrrlichtDevice *device =
            createDevice( video::EDT_DIRECT3D9, dimension2d<u32>(640, 480), 32,
                false, false, false, 0);
 
        if (!device) return 1;
 
    device->setWindowCaption(L"Hello World! - Irrlicht Engine Demo");
    IVideoDriver* driver = device->getVideoDriver();
    ISceneManager* smgr = device->getSceneManager();
    IGUIEnvironment* guienv = device->getGUIEnvironment();
 
   /*guienv->addStaticText(L"Hello World! This is the Irrlicht Software renderer!",
         rect<s32>(10,10,260,52), true);*/
 
    IGUIFont *nFont = guienv->getBuiltInFont(); /* guienv->getFont("myfont.xml");*/
 
    IAnimatedMesh* mesh = smgr->getMesh("sydney.md2");
        if (!mesh)
        {
            device->drop();
            return 1;
        }
    IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode( mesh );
 
    if (node)
        {
            node->setMaterialFlag(EMF_LIGHTING, false);
            node->setMD2Animation(scene::EMAT_STAND);
            node->setMaterialTexture( 0, driver->getTexture("sydney.bmp") );
        }
 
    smgr->addCameraSceneNode(0, vector3df(0,30,-40), vector3df(0,5,0));
 
    while(device->run())
        {
 
            driver->beginScene(true, true, SColor(255,100,101,140));
 
            if(nFont) nFont->draw(L"Testuje sobie bal bla", core::rect<s32>(10,10,260,52), video::SColor(0,0,0,0));
            smgr->drawAll();
            guienv->drawAll();
            driver->endScene();
        }
        device->drop();
 
    return a.exec();
}
 

//Edit:
Ok, thank you - it works, and I had set transparency.

You should put the line after smgr->drawAll(). Otherwise, it will appear as if the text is behind all your 3D nodes.
