Automatic OGL activate in EXE mod.

I'm working on a small mod to add files to give proper animation & color changes to models by use of new extrernal files. I saw OGL automatically active in TML, but I can't figure it out. I had some theories, but they failed. Also, I'm not using the SVN, because I can't seem to download a subversion client.

Wasn't TML using a batch file? With -opengl?

Np, it went OGL straight from the exe.

Oh, I was just enabling that the other day, in i_video.c or win_vid.c, there's a bit of code where it switches to software by default in I_StarupGraphics :

(This is from the SDL code)

Original:

#ifdef HWRENDER
if (M_CheckParm("-opengl") || rendermode == render_opengl)
{
rendermode = render_opengl;
HWD.pfnInit = hwSym("Init",NULL);
HWD.pfnFinishUpdate = hwSym("FinishUpdate",NULL);
HWD.pfnDraw2DLine = hwSym("Draw2DLine",NULL);
HWD.pfnDrawPolygon = hwSym("DrawPolygon",NULL);
HWD.pfnSetBlend = hwSym("SetBlend",NULL);
HWD.pfnClearBuffer = hwSym("ClearBuffer",NULL);
HWD.pfnSetTexture = hwSym("SetTexture",NULL);
HWD.pfnReadRect = hwSym("ReadRect",NULL);
HWD.pfnGClipRect = hwSym("GClipRect",NULL);
HWD.pfnClearMipMapCache = hwSym("ClearMipMapCache",NULL);
HWD.pfnSetSpecialState = hwSym("SetSpecialState",NULL);
HWD.pfnSetPalette = hwSym("SetPalette",NULL);
HWD.pfnGetTextureUsed = hwSym("GetTextureUsed",NULL);
HWD.pfnDrawMD2 = hwSym("DrawMD2",NULL);
HWD.pfnSetTransform = hwSym("SetTransform",NULL);
HWD.pfnGetRenderVersion = hwSym("GetRenderVersion",NULL);
// check gl renderer lib
if (HWD.pfnGetRenderVersion() != VERSION)
I_Error ("The version of the renderer doesn't match the version of the executable\nBe sure you have installed SRB2 properly.\n");
#ifdef _WIN32_WCE
vid.width = 320;
vid.height = 240;
#else
vid.width = 640; // hack to make voodoo cards work in 640x480
vid.height = 480;
#endif
/*
* We want at least 1 bit R, G, and B,
* and at least 16 bpp. Why 1 bit? May be more?
*/
SDL_GL_SetAttribute(SDL_GL_RED_SIZE, 1);
SDL_GL_SetAttribute(SDL_GL_GREEN_SIZE, 1);
SDL_GL_SetAttribute(SDL_GL_BLUE_SIZE, 1);
SDL_GL_SetAttribute(SDL_GL_DEPTH_SIZE, 16);
if (!OglSdlSurface(vid.width, vid.height, (USE_FULLSCREEN)))
if (!OglSdlSurface(vid.width, vid.height, !(USE_FULLSCREEN)))
rendermode = render_soft;
}
#else
rendermode = render_soft; //force software mode when there no HWRENDER code
#endif

Method I used:

#ifdef HWRENDER
rendermode = render_opengl;
HWD.pfnInit = hwSym("Init",NULL);
HWD.pfnFinishUpdate = hwSym("FinishUpdate",NULL);
HWD.pfnDraw2DLine = hwSym("Draw2DLine",NULL);
HWD.pfnDrawPolygon = hwSym("DrawPolygon",NULL);
HWD.pfnSetBlend = hwSym("SetBlend",NULL);
HWD.pfnClearBuffer = hwSym("ClearBuffer",NULL);
HWD.pfnSetTexture = hwSym("SetTexture",NULL);
HWD.pfnReadRect = hwSym("ReadRect",NULL);
HWD.pfnGClipRect = hwSym("GClipRect",NULL);
HWD.pfnClearMipMapCache = hwSym("ClearMipMapCache",NULL);
HWD.pfnSetSpecialState = hwSym("SetSpecialState",NULL);
HWD.pfnSetPalette = hwSym("SetPalette",NULL);
HWD.pfnGetTextureUsed = hwSym("GetTextureUsed",NULL);
HWD.pfnDrawMD2 = hwSym("DrawMD2",NULL);
HWD.pfnSetTransform = hwSym("SetTransform",NULL);
HWD.pfnGetRenderVersion = hwSym("GetRenderVersion",NULL);
// check gl renderer lib
if (HWD.pfnGetRenderVersion() != VERSION)
I_Error ("The version of the renderer doesn't match the version of the executable\n");
#ifdef _WIN32_WCE
vid.width = 320;
vid.height = 240;
#else
vid.width = 640; // make voodoo cards work in 640x480
vid.height = 480;
#endif
/*
* We want at least 1 bit R, G, and B,
* and at least 16 bpp. Why 1 bit? May be more?
*/
SDL_GL_SetAttribute(SDL_GL_RED_SIZE, 1);
SDL_GL_SetAttribute(SDL_GL_GREEN_SIZE, 1);
SDL_GL_SetAttribute(SDL_GL_BLUE_SIZE, 1);
SDL_GL_SetAttribute(SDL_GL_DEPTH_SIZE, 16);
if (!OglSdlSurface(vid.width, vid.height, (USE_FULLSCREEN)))
if (!OglSdlSurface(vid.width, vid.height, !(USE_FULLSCREEN)))
rendermode = render_opengl;
#else
rendermode = render_opengl; // OpenGL by default
#endif


There's different code in the windows version, just search for in the code for "-opengl" and you should find what you're looking for

Thank you. I have been looking in the wrong places all this time.
EDIT: It looks like this in Win:
And I changed it to this:
So now you can type -software in the command line to go software, (but in my little mod, it'll look stupid.)

Not if you use the net launcher =P

What? Do you mean that you can't go software from that with the net launcher? Well, that is true, with check boxes, but the net launcher has a command line in main options.

So for software mode on your mod I'm guessing your gonna have to create a batch file with -software for software mode then =/

That's an option. It can still easily be done through the launcher, and the old launcher's code it supplied, so I could try and make one to work with this. (Note, I said try. I have extremely limited experience with this stuff.)
