Graphics / 64-bit textures?

« on: January 05, 2014, 01:22:54 pm »

Hi, I need to create a texture with a 64-bit color depth (or at least 32 bit). Is that possible? If so, how?

Graphics / std::list of RenderTextures [Solved, stupid question]

« on: December 14, 2013, 04:43:50 pm »

Hi, since RenderTextures are nonCopyable, is it possible to store them in a list ?
edit1: In other words, can I create dynamically allocated textures?
edit2: Yes I can

Graphics / Sprite::SetScale broken?

« on: November 23, 2013, 08:32:19 pm »

So, I'm setting up a window with a resolution of 800x400 and I'm creating a 800x800 RenderTexture. Then I'm drawing a circle an a square onto the RenderTexture. Now I'm putting the texture into a sprite and setting the sprite scale to 0.5, 1. Now this should draw the sprite without any distortion, but it doesn't. The circle is stretched vertically by a factor of ~1.3. Why?

edit: Got it, scale is relative to the sprite size, not the window size. Used view now and the follwing code to set the size:

       
        float innerRatio = defaultContentSize.x / (float)defaultContentSize.y;
        float outerRatio = winSize.x / (float)winSize.y;
       
        if(innerRatio > outerRatio)
        {
                contentView.setSize(sf::Vector2f(defaultContentSize.x, defaultContentSize.y/outerRatio));
        }
        else
        {
                contentView.setSize(sf::Vector2f(defaultContentSize.x*outerRatio, defaultContentSize.y));
        }
        contentView.setCenter(Tools::VDiv(defaultContentSize, 2));

Graphics / Resolution-Independent Rendering?

« on: November 23, 2013, 04:35:14 pm »

Hi,
I'm new to smfl and I was wondering how I can scale my content to fit into the window without having a global scale variable which has to be used in every frame. I tried a simple approach with RenderTextures, but calling the GetTexture() method every frame seems to be VERY slow. Any ideas?

General / vs2012: toAnsiString returns scrambled data [Solved]

« on: November 18, 2013, 08:40:17 pm »

Hi, when I'm trying to covert a sf string to a regular c++ string, I'm getting a broken value. When debugging I'm getting a wrong value for size and <Error reading characters of string.> for each character. What's going on here ?


edit: Solved, didn't link the debug dlls, my bad!
