General / Strange error "Unhandled event type: 0"

« on: June 21, 2015, 10:54:21 am »

Hello!

I'm using QSFMLWidget from 1.x turorual which I have got working with SFML2.3.
On implementing event handling system I've faced a strange error.

X Extensions:
        Generic Event Extension - First event: 0
        SHAPE - First event: 64
        MIT-SHM - First event: 65
        XInputExtension - First event: 66
        XTEST - First event: 0
        BIG-REQUESTS - First event: 0
        SYNC - First event: 83
        XKEYBOARD - First event: 85
        XC-MISC - First event: 0
        XFIXES - First event: 86
        RENDER - First event: 0
        RANDR - First event: 88
        XINERAMA - First event: 0
        Composite - First event: 0
        DAMAGE - First event: 90
        MIT-SCREEN-SAVER - First event: 91

        X-Resource - First event: 0
        XVideo - First event: 92
        XFree86-VidModeExtension - First event: 0
        XFree86-DGA - First event: 94
        DRI2 - First event: 101
        GLX - First event: 103
        NV-GLX - First event: 0
        NV-CONTROL - First event: 120
Unhandled event type: 0
Report this to the SFML maintainers if possible

Here is my function:

void QSFMLCanvas::OnUpdate()
{
    sf::Event event;
    while (pollEvent(event)) {
        switch(event.type)
        {
            case (sf::Event::MouseButtonPressed) :
                qDebug() << "mouse clicked"; // Event never handled
                //mousePressedEventHandling(event);
                break;
            case (sf::Event::MouseMoved) :
                qDebug() << "mouse moved"; // Event handled
                //mouseMovedEventHandling(event);
                break;
            case (sf::Event::KeyPressed) :
                qDebug() << "key pressed"; // Event handled
                break;
            default:
                break;
        }

    }
    // Clear screen
    clear(sf::Color(0, 0, 0));
    engine.render();
}

As I can see in my console, none of the events are handled.
I'm using Linux.

Graphics / Terrain questions: general approach, texture splatting, maps

« on: September 05, 2014, 04:12:44 pm »

Greetings to everybody. I'm new to game creating, OpenGL, SFML and you forum )
Currently I'm writing my own terrain engine, so to say...  I intend to make a level editor in the future. My ambitious plan is to make something like this:


Looks like an impossible task for a newbie because of using custom shaders and abstruse formulas, but I want to implement at least texture splatting on edges...

Struggling with google I hoped to find some tutorials about making such terrains but all my requests were to no avail.

So
1) My current approach is to make a vexel array for each land area containing different textures. Somehow I want to make texture splatting in vexel array intersections. By the way I use vertex arrays of different types, not only quads.. Does it make sense in order to draw a terrain?
2) I have heard about using alpha maps for splatting textures. But I have no idea how to implement this... If it is a large topic could anyone advise me some articles or literature about this?
3) I'll repeat that I'm new to SFML and I don't have any knowledge of OpenGL actually. Can I reach my goals learning SFML only? Or do I have to learn OpenGL basics first?

Thank you for your further helpful answers.
