I have ported some directx tutorial back in 2005... This time I play around again with directx and also with tango. But I have a problem even with the old directx code of mine - which of course worked on the old dmd compiler. Right now the compiler and tango verisons are: tango-0.99.4-bin-win32-dmd.1.024.zip

Bit of a help would be appreciated, the attached code should display a triangle.

Have you seen the Win32 API bindings project? They seem to have ported some or all of the DirectX headers: http://www.dsource.org/projects/bindings/wiki/WindowsApi

Also, check out this in-progress 3D game engine written in D: http://www.yage3d.net/

Yep, I am aware of the bindings, also I use them in newer code - in the attached code I tried to use a minimal version, and also a simple one which worked well with dmd back in 2005.

Thanks for the link to Yage. Unfortunately Yage uses openGL.

i tried your attached app and it works for me with dmd2.010 i just changed the depencies to get it working with phobos, cause i dont use tango.

He probably meant this link www.dsource.org/projects/nonagon

Well, by working you mean you see the triangle (instead of the simple backgroud)?
I'll try that with phobos, also with dmd2.010, if that difference causes this then there is an interesting bug somewhere...

Thanks,

Whoa I see this is what happening. It works with dmdv1.026 and phobos. I am investigating this issue, right now I suspect tango - somebody from there please lend me a hand.

There is a problem - difference - between dmdc1.0124 AND default phobos versus "tango-0.99.4-bin-win32-dmd.1.024".

See the code below:

// A structure for our custom vertex type
struct CUSTOMVERTEX
{
    FLOAT x, y, z, rhw; // The transformed position for the vertex
    DWORD color;        // The vertex color
};

// Initialize three vertices for rendering a triangle
static CUSTOMVERTEX[3] vertices =
[
	{ 150.0f,  50.0f, 0.5f, 1.0f, 0xffff0000, }, // x, y, z, rhw, color
	{ 250.0f, 250.0f, 0.5f, 1.0f, 0xff00ff00, },
	{  50.0f, 250.0f, 0.5f, 1.0f, 0xff00ffff, },
];

int a = vertices.sizeof;

a is 120 with phobos, 60 with tango.


Some related question: is it possible for tango and phobos to live side by side, also edit and debug side by side? (Something like an automated test that is capable to compare phobos vs tango build?) It isn't simple to find a difference like this one.

Or is this difference intentional to begin with?

I don't see why the size would differ based on the standard library, that's really odd.  The library should have no effect on this code.  Regardless, you should put align(1) on the CUSTOMVERTEX struct declaration, which SHOULD make it 60 in both.

I'm not sure why you'd want to.  There's tangobos which is an implementation of phobos in Tango, but you should really either target one, or if you really must, use "version(Tango) { ... } else { ... }" statements.

Finally I have found the time to investigate this issue. And the winner is...

Same code will follow with phobos then with tango:

//phobos
import std.c.windows.windows;

struct CUSTOMVERTEX { FLOAT x; };
static CUSTOMVERTEX[3] vertices = [ { 150.0f } ];

void main() { printf ("%d",vertices.sizeof); }

Prints 12.

//tango
import tango.sys.win32.Types;
import tango.stdc.stdio;

struct CUSTOMVERTEX { FLOAT x; };
static CUSTOMVERTEX[3] vertices = [ { 150.0f } ];
void main() { printf ("%d",vertices.sizeof); }

Prints 24.

The difference lies:

Phobos, \dmd\src\phobos\std\c\windows\windows.d:
alias float FLOAT;

Tango, D:\D\import\tango\sys\win32\Types.di:
alias double FLOAT;

(Before you ask, I use type FLOAT - uppercase - because I copy some directx code, which already uses that.) With directx on win32, the phobos approach is working, Tango FLOAT produces errors.

Is this intended in Tango? Is there already code requiring FLOAT to be double?

The problem in the original post is disappears (and the directx triangle appears), if I use float instead of FLOAT (so double in Tango).
