Hi guys, i'm having some problems, after my attempt to try getting CEGUI working in a directx game (by injected a dll) i decided to try OpenGl with Quake 3.

My problem is though, when using:

Code: Select all

CEGUI::System::getSingleton().renderGUI()

It crashes the game, but, when commenting it out, it looks like the CEGUI stuff is being created sucessfully. Here is the log. When the "RenderGUI" is not commented out, it doesn't create a log.

I've tried placing "RenderGUI" in glViewport and glEnable but both crash. I'm injecting a dll which hooks opengl rendering functions. If you could help it would be greatly appreciated.

Also, is it possible to use CEGUI without having to place "CEGUIBase.dll" and "OpenGLGUIRenderer.dll" in the game directory?

My OpenGL is a little rusty these days, but you arn't doing the rendergui between a glBegin & an glEnd are you?

Maybe you could hook glClear (and call the original clear & then renderGUI) or a glFlush (and call renderGUI before the real glFlush).

I'm sure there are ways, i can't think of any good ones right now though, if i solve the problem for my own hack, i'll try to get back to you

Hi,

about the DLLs: do you mean that you'd like to have them in a different location? Or would you like to link statically so that you don't have any DLLs? You can add the CEGUI's bin folder to your PATH, so each CEGUI application can find the most recent DLL's. You may link statically as of version 0.5, which is not released yet.

For the rendering you might also check this code from the layout editor, which uses OpenGl in a non-cegui application:
http://svn.sourceforge.net/viewcvs.cgi/ ... p&rev=1153

The method "void EditorCanvas::Render()" might give some insights. Althouth "glBegin()" and "glEnd()" are wrapped by the wxWidgets methods presumably.

Good luck!

Hey, now there is some good thinking!
The PATH hadn't even occured to me, although, static linking sounds like a good option as well.

When i finally figure out the slowdown i'm having, i'll implement one of the two (depending ofcourse on when 0.5 comes out

)
