Impossible to create rendertexture?...

[zombiekiller222]

Code: [Select]

using System;
using SFML.Window;
using SFML.Graphics;

namespace Utilities
{
public class Utilities
{
public static Sprite TextToSprite (Text text)
{
FloatRect textb=text.GetRect();
RenderTexture rtex = new RenderTexture((uint)textb.Width, (uint)textb.Height);
rtex.Draw (text);
return new Sprite(rtex.Texture);
}
}
}




Returns an error:

Failed to share the OpenGL context
Impossible to create render texture (failed to link the target texture to the fr
ame buffer)

The failed to create an Opengl texture is a seperate error, I would assume, which causes the second.

Can you show a complete and minimal source code that reproduces the problem?

With the other peice of the code:

Code: [Select]

using System;
using SFML.Window;
using SFML.Graphics;
using SFML.Audio;
using Utilities;

namespace IsoGame
{
static class Program
{
private static uint width = 800;
private static uint height = 600;
static void Main ()
{
RenderWindow window = new RenderWindow(new VideoMode(width, height), "Retrogons");

while (true)
{
Render(window);
}

}

private static void Render (RenderWindow window)
{
window.Clear();
Text error = new Text("Play");
                        error.Position = new Vector2f(width/2, height/2);
Utilities.Utilities.TextToSprite(error);
window.Display();
}
}
}

Works for me, except that the text position is out of the render-texture area

But no error message, and with position at (0, 0) it works as expected.

Strange... What could the problem possibly be? Also, is my method of converting a text into a sprite bad? Btw, off topic, but why is image.Pixels 1 dimensional?

What could the problem possibly be?

Your graphics drivers

Also, is my method of converting a text into a sprite bad?

No. But I hope that you have a good reason for doing so

Btw, off topic, but why is image.Pixels 1 dimensional?

Because internally, the pixels are stored in a contiguous array in memory. Much easier to work with (at least from a C++ point of view).

I'm using an intel integrated graphics card, and I'm not sure which driver I should update? The chipset driver, or some other driver?

Oh... so a driver update may not be enough :lol:

I don't know, I never worked with integrated graphics.
