[coding] OpenGL draw custom text?

**qazz** · 02-28-2009

Well i have the will to code a dll file with some simple patching memory functions for start.

But part of the main goal is for me to create a menu for the hack, so you can toggle easily anything you desire.

I noticed that in WoW.exe's memory is loaded opengl32.dll

I have the following 2 procedures (i code in delphi btw)

Code:

 
procedure glPrint(bs: integer; s: pchar); // draw text
begin
glPushAttrib($00020000);
oldglListBase(bs - 32);
oldglCallLists(length(s), $1401, s);
glPopAttrib;
end;

Code:

 
procedure DrawMenuText(x, y, bs: integer; s: pchar; red, green, blue: single); // draw menu text
begin
glColor4f(0, 0, 0, 1); // set gray color
oldglRasterPos2f(x+3, y+3); // set text coord
glPrint(bs,s); // print text
 
glColor4f(red,green,blue,1); // set new color
oldglRasterPos2f(x,y); // set text coord
glPrint(bs,s); // draw colored text
end;

So far so good ... this code is not working for me, nothing is being drawn if i use the following for example:

Code:

drawmenutext(swidth-80-80,120,base,'my greeny text is here',0,1,0);

So anyway, my question is for you to help me a little bit more what should i use to draw 2D custom text (with custom coords,color) in WoW?

Please excues my bad english, and i am sorry if i posted it in the wrong section but i suppose that dll injections and hooking ogl functions should be in "memory editing" :wave:

WoW uses Direct X...

Yeah, but who actually uses that? Even Wine does better when its running under DX.

Not on a Mac, OpenGL support probably stemmed solely because of the Mac;

But what the above posters said, Either use DirectX or Enable your OpenGL.

Pfft. Mac. Just download linux and throw some money in the bin, its pretty much the same thing.

Have a look at WoWX.

Well it has quite it's differences, even though they both stem from a Unix background; It's why you see a WoW essentially "Emulated" on Linux and ran Native on Mac. Since Linux is growing in video Driver support and runs amazingly with OpenGL; I would like to see Blizzard blow some live into WoW by getting a 5-10 man team to screen the code and get a compiled version running native for Linux. I think it would be a sight to see.

Lol, it was a joke.

Wine is far from 'emulated' though.

Notice the Quotations " ", I know about Wine and how it does things; But really in General it would fall under the, not quite Emulation, but "Emulation" tree of things.

I look at it that way because it is not really Windows. It may take calls and, if you will, redirect them to viable Unix calls and Converts DirectX calls to OpenGL calls etc; But that in a sense is almost emulation. Just because they are taking one thing and replacing it with something that can do, to our eyes, the same thing; But Emulation is the art of taking one thing and replacing it with another.

I also caught the joke, I was just bored and figured I would stir the pot with some "seriousness"

I know you threw "emulation" in quotations but even then its still a poor choice of words. I realize what you meant, but I was pointing out that even that may have been a little misguided. Its not emulation, nor is it "almost emulation", at least not in the sense of the word that is normally used in the software development context.

Its beside the point though. My main point was to do with ripping on Macs, so lets get back to doing that.
