General / glDrawArrays crash

« on: October 13, 2015, 04:38:18 pm »

My application keeps crashing with unhandled exception when I add glDrawArrays.

I have tried to glDisableClientState but it doesn't help

Is it something to do with SFML? I'm nearly sure OpenGL code is correct.

do you really expect being able to find binaries for all of them built with your compiler of choice?

Yes, I expect every quality library to provide binaries, this should be automated to a one click process on the creators side.

No offence but you sounded douchey.

Could someone provide binaries for visual studio 2013? Pretty please?

I have spent last two hours getting cmake to work and now it doesn't compile

DotNet / [C#][SFML 2.1] Passing RenderStates makes object dissappear.

« on: January 13, 2014, 01:31:38 am »

When I call draw with just 2 params it works fine, but when I want to set texture through RenderStates triangle is not displayed.

Texture loads well, can draw it without issue as Sprite.

I have also tried creating and filling RenderStates object every loop with no effects.

What am I doing wrong here?

public class Terrain
        {
                List<Vertex> triangles = new List<Vertex>();

                Texture imgGrass;
                Sprite sprite;
                RenderStates states = new RenderStates();

                public Terrain ()
                {
                        imgGrass = new Texture("Data/Gfx/grass.png");
                        imgGrass.Repeated = true;
                        states.Texture = imgGrass;
                        sprite = new Sprite(imgGrass);

                        Vertex vertex = new Vertex();

                        vertex.Position = new Vector2f( 32, 32 );
                        vertex.Color = Color.White;
                        vertex.TexCoords = new Vector2f( 0, 0);

                        triangles.Add(vertex);

                        vertex.Position = new Vector2f( 256, 32 );
                        vertex.Color = Color.White;
                        vertex.TexCoords = new Vector2f( 100, 0);

                        triangles.Add(vertex);

                        vertex.Position = new Vector2f( 128, 128 );
                        vertex.Color = Color.White;
                        vertex.TexCoords = new Vector2f( 0, 100);

                        triangles.Add(vertex);
                }

                public void Draw(RenderWindow window)
                {
                        //window.Draw(sprite);

                        window.Draw(triangles.ToArray(), PrimitiveType.Triangles, states);
                }
        }

Graphics / SOIL unhandled expression

« on: January 07, 2012, 02:11:50 pm »

I am trying to load texture into OpenGL using soil with something like this:

Code: [Select]

int LoadGLTextures()
{
    /* load an image file directly as a new OpenGL texture */
    texture[0] = SOIL_load_OGL_texture
        (
        "bg.png",
        SOIL_LOAD_AUTO,
        SOIL_CREATE_NEW_ID,
        SOIL_FLAG_INVERT_Y
        );

    if(texture[0] == 0)
        return false;


    // Typical Texture Generation Using Data From The Bitmap
    glBindTexture(GL_TEXTURE_2D, texture[0]);
    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);
    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);

    return true;                                        // Return Success
}

And call

Code: [Select]

glEnable( GL_TEXTURE_2D );
glShadeModel( GL_SMOOTH );

before it.

App launches and returns unhandled exception here:

Code: [Select]

// SOIL.c
int query_NPOT_capability( void )
{
    /*  check for the capability    */
    if( has_NPOT_capability == SOIL_CAPABILITY_UNKNOWN )
    {
        /*  we haven't yet checked for the capability, do so    */
        if(
            (NULL == strstr( (char const*)glGetString( GL_EXTENSIONS ),
                "GL_ARB_texture_non_power_of_two" ) )
            ) //############ it points here ############//
        {
            /*  not there, flag the failure */
            has_NPOT_capability = SOIL_CAPABILITY_NONE;
        } else
        {
            /*  it's there! */
            has_NPOT_capability = SOIL_CAPABILITY_PRESENT;
        }
    }
    /*  let the user know if we can do non-power-of-two textures or not */
    return has_NPOT_capability;
}

Am I missing other initialisations?

SOIL_CAPABILITY returns -1
has_NPOT_capability returns -1

General discussions / SFML 2.0 changes / progress

Yes, there's a topic on the first page of the General forum.

Ah, right, had to be blind

Will it support OpenGL 4.x ?

Is there SFML 1.6 -> 2.0 changes list?
Haven't found it anywhere.

And how is it progressing? Can we expect full version soon?

SFML projects / Conway's game of life

« on: January 02, 2012, 09:02:28 pm »

Haven't yet, waiting for it to be released, I'll play some more time with 1.6 and eventually move then

Also yes, tried with shapes, but it was 2x slower.

Does it create new object with every call?

Code: [Select]

AppWindow.Draw( sf::Shape::Rectangle( i * GridSpacing, j * GridSpacing, i * GridSpacing + GridSpacing, j * GridSpacing+ GridSpacing, sf::Color( 0, 0, 255 ), 0, sf::Color::Black ) );

To be honest didn't though about it before.

No, I simply apply single image for single sprite at initialisation point:

Code: [Select]

imgBlueLifeForm.Create( 16, 16, sf::Color::Blue );
	BlueLifeForm.SetImage( imgBlueLifeForm );

and draw it this way:

Code: [Select]


for( int i = 0 ; i < 64 ; i ++ )
	{
		for( int j = 0 ; j < 48 ; j ++ )
		{
			if( isAlive[i][j] == true )
			{
				BlueLifeForm.SetPosition( i * GridSpacing, j * GridSpacing );
				AppWindow.Draw( BlueLifeForm );
			}
		}
	}

SFML projects / Conway's game of life

« on: January 02, 2012, 03:27:45 pm »

Here's my result of few days of learning sfml

My 'framework' took me 3 days to look like a framework

and game itself one day.

I've started with rendering grid and cells using primitives, but it was definitely bad idea, now grid and cells are just sprites, whereas I noticed, that filling image with color in-code, gives ~20fps performance for me.

Without any cells shown it runs with 900fps, with 100 cels about 260 fps.

I'm quite sad with sfml (1.6) rendering speed, maybe just my code is wrong, but for now showing for example many tiles is just impossible.

I'll probably extend this 'game' as a part of learning openGL

LMB - set cell talive
RMB - set cell dead
G - toggle grid
P - pause/unpause simulation
+/- change speed of simulation

Graphics / Insert images after App.Display();

« on: January 02, 2012, 12:29:39 pm »

It's hard to understand you, but as Tex killer said, you have to put App.Clear on the beggining of the loop, or right after App.Display. That's why you can't see 'miss' object when you press key.

App.Clear fill the whole screen with some color, so you won't see anything displayed before you called it.

And how does it handle drawing many sprites? Is it actually able to run over 60fps with 1024x768 screen fullof 16bit tiles? Does it use OpenGL to render it or SFML graphics?
