I've decided, in order to spice up my motivation, I'm going to take requests for demo applications to create.

I'll make either another A.cc javascript extension or an example application for the Thing library (a D3D/OpenGL/Allegro wrapper in C++).

Ideally your request / idea:

• Has a good ratio of time put in to coolness coming out, or

• Showcases something cool (about the Thing library), or

• Would be really cool

I'll throw something together

Alright, here we go. The Sprite Thing example is now complete. Download Sprite Thing Example.

Heres a preview of the source code:

That was in by mistake .

Hmm... Try installing direct X 9 maybe?

Yes this is the way to switch from OpenGL mode to D3D mode.

The d3dx9.dll dependency is stuck for now. In the future I plan to make the dll dynamically loaded and simply make the D3D driver fail if it is not found. For now the only way to remove the dependency is to compile with the NO_D3D macro defined.

I'm not sure why its so large for you... did you strip the executable?

Yes this is supported by every drawing method. The parameter its controlled with is 'tint'. Heres the Tint class for reference:

struct Tint {
    
    float r, g, b, a;
    
    // True if the blit should be done with additive blending.
    bool additive;
    
    Tint(float red = 1, float green = 1, float blue = 1, float alpha = 1, bool add = false)
        : r(red), g(green), b(blue), a(alpha), additive(add)
    {
        
    }
};

IIRC D3D was incorporated in DirectX 8. There was some good reason that made since way back when to just use version 9 instead of 8, though I don't remember it just now.

Any way you could get a back-trace on which line is failing in conf.cpp?

I play games using DirectX 9.0b without problems, I don't know what could be wrong?

It seems that this is the part of code that throws the error:

I installed DirectX 9.0c, and now the sample works with D3D:D
However the example looks different when D3D mode is used.

The circle scaled blit code only works with HARDWARE(why don't you call it OPENGL?)
It does not work in SOFTWARE and D3D modes.
The star looks antialiased only with HARDWARE, I think it should look the same with D3D.

DirectX90C.DevPack

I was doing some testings.(test.cpp and bitmap attached.)

I created a tint to set the opacity in 50%, it works in D3D, but it does not work in HARDWARE.
Additive = true

In FULLSCREEN and D3D after the program finishes, my desktop remains in 640x480, and the program continues resident in memory.

In FULLSCREEN and HARDWARE my monitor shows this message "238Hz frequency not supported"
I also have this problem with some OGL and OL games. Is there a way to force a standar refresh rate like 60, 85, or 100hz? In AllegroGL I use Allegro's request_refresh_rate(x) to solve it, but this time that did not work.

tileBlitToScreen works fine in HARDWARE but it shows something weird in D3D mode.

I set antialiasing to 8x but it looks aliased.
If I set antialias to Application controlled, can I control it with some lines of code from my application?

It's my fault!, sorry.

And it is still there, I tried your new conf.cpp but I did not notice any difference.
In FULLSCREEN and HARDWARE I get the aforementioned message about the unsupported frequency.
But it's worse in FULLSCREEN and D3D. At first it works without problem, but when the application ends, it remains in memory and set my desktop to 640x480 and it changes my desktop wallpaper, not a nice thing at all.

I would like to use your Thing in my current project, I have found it extremely easy to use, however these little problems should be fixed first.
If I only knew something about D3D:'( I think I could fix those little problems.
Can you recomend me a tutorial for beginners?

My monitor does not allow non-standar refresh rates, when that happens it goes black and it shows a message saying "132k/239Hz frequency out of range", well in this particular case it was 239Hz.

That's why I need to force a standar refresh rate like 60, 70, 72, 75, 85, 90, or 100Hz, I don't want my game running at a higher refresh rate, that only happens in FULLSCREEN and HARDWARE mode.

In FULLSCREEN and D3D mode it works, but it seems that there is something wrong in the D3Dshutdown(), because once the application ends, it remains in memory and it makes a mess in my desktop, it changes the resolution to 640x480, icons missed, really ugly.

In my PC when I try to close the application(in FULLSCREEN), it fails to close, and it reamins in memory and it makes a mess in my desktop, and I have to kill the application manually, yes I think this could be related.

Yes, I tried all AllegroGL examples and they work.
I also tried an old Nehe example modified to be compiled with AllegroGL(with a lot of deprecated AGL functions), but this one failed to find a supported refresh rate and my monitor displayed the message I already said, but I fixed this problem with Allegro's set_refresh_rate();
My video card is a FX5700LE with 128MB, it supports pixel/vertex shader 2.0+, I think it should not be problems with this card.
