I'll try, the next time I'd be near that computer, but it's not a code problem - on my home desktop there's no tearing.

No, In the animation I keep removing the first frame and then draw the next one.

DotNet / Tearing in clear textures.
« on: May 17, 2012, 10:41:42 pm »
When I run an animation that involves a partly clear (invisible) texture on a slow computer, there's "static" tearing which disrupts the view. This happens regardless of Vsync or whether there's a framerate limit set. Is there a known cause for this?

Sorry, couldn't parse it down to the bare minimum, so this came out a bit long.
Running this on debug mode in VS2010 opens a large window with smal green animation. After about two minutes it'll crash.
EDIT: Another run didn't crash, but began blinking white. The one after threw a "divide by zero" exception after ten seconds. As I said, non-deterministic.

DotNet / RenderTexture / Texture problems
« on: May 15, 2012, 01:07:54 pm »
At some point after creating a RenderTexture, drawing to it, displaying & saving the texture in a sprite, some odd transformation happen - When I'll try to display the sprite, I'll get an error message - either a "tried to divide by zero" after the inner texture's parameters change (sometimes to 0,0, sometimes to impossibly large numbers), or a "Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
This happens at a non-deterministic stage, and not at the first time the texture is displayed, and I failed to find a definite result to it. Could this be connected to garbage collection of the RenderTexture after it left operational scope, and something in it's destructor changing it's texture afterwards?

thank you very much.
laurent - how can UI set it back? Image.Pixels is readonly, and the array doesn't have x,y coordinates to use in Image.setPixel.
omeg - I'm not certain I know what you're talking about. Can you please explain?

is this function a reasonable replacement, or is there a more efficient way?
for (uint i = 0; i < img.Size.X; i++)
{
for (uint j = 0; j < img.Size.Y; j++)
{
if (img.GetPixel(i, j).Equals(Color.White))
{
img.SetPixel(i,j,new Color(0,0,0,0));
}
}
}
for (uint i = 0; i < img.Size.X; i++)
{
for (uint j = 0; j < img.Size.Y; j++)
{
if (img.GetPixel(i, j).Equals(Color.White))
{
img.SetPixel(i,j,new Color(0,0,0,0));
}

When I try to use the command, I get the error message "Unable to find an entry point named 'sfImage_createMaskFromColor' in DLL 'csfml-graphics-2'.". This happens with the 2.0 RC version.
this happens even with
static int Main(string[] args)
{
SFML.Graphics.Image img= new SFML.Graphics.Image(10, 10, SFML.Graphics.Color.White);
img.CreateMaskFromColor(SFML.Graphics.Color.White);
return 1;
}
for now I just iterate over the pixels, but if the function could be fixed, it'll help. Thanks!

« on: April 20, 2012, 09:47:26 am »
So, to explain why I failed to find a minimal working problem - apparently it's not the Texture, or the original images - Sprites made from both are running. There's no discernible cause for this, no condition that I could isolate through prints, etc. Frankly, at the level of information open to me, I can't discern any difference between the Sprites that crash (and they're very few) and those that don't.
The only thing I know is that sometimes, when calling line 165 in Sprite.Draw, states.Transform *= Transform, the "right" variable will be null. Since this.Transform isn't null, but is Matrix(System.Single)[], I don't really understand what is happening.

« on: April 19, 2012, 11:01:44 pm »
I'm still looking at reducing the code, but now I've noticed that the only null part of the Sprite is myInverseTransform, and that under InverseTransform there's a message "'((SFML.Graphics.Transformable)(sprite)).InverseTransform' threw an exception of type 'System.AccessViolationException' SFML.Graphics.Transform {System.AccessViolationException}".
Is this a hint towards what happened?
EDIT: I now see that every object has it as null. So I don't see what do I get the null exception on - the Sprite's definitely not a null, and I can't seem to reduce this to a minimal case that wtill pops the error.

« on: April 19, 2012, 09:46:14 pm »Do you really need the same complexity to reproduce it? I mean, if it's a bug in SFML then it can probably be reproduced easily. If not, then the problem is caused by your program, and there's nothing I can do.
Oh, I don't know what I need to reproduce it. Currently it's very complex, and I'll try to focus on the minimal needed to reproduce it.
eXpl0it3r - I don't use OpenGL, but I do set it to Active(false) on the thread it's created.

Argh. This is a problem that spans the interaction between several objects and threads. I can try to minimise it, but will it still be worthwhile if the code I'll upload will be quite long?

Yes, I didn't run the OpenGL example program. I tried once and errors popped ("output path not defined"), and since I wasn't interested in OpenGL didn't bother with it.
There's no global sprite. There's one that is created before the window, but it gets displayed well - it's the background, and the program runs and displays stuff (and the background) before crashing. It happens when drawing new sprites.
