CEGUI Implementation Issues

[Seraphis]

Hello community,

 

I was just looking through the CEGUI tutorial by Laurens and the CEGUI forums for an answer to this little frustrating issue but all to no avail.

 

 

Essentially the problem is that I keep getting an access violation when I run the program and I'm pretty sure I narrowed it down to the line thats causing the exception.

 

CEGUI::SchemeManager::getSingleton().create("TaharezLook.scheme");

 

Now, I have a the TaharezLook.scheme in my gui/schemes folder which is in the main folder of my application.

 

I'm using Visual Studio 2010 with the 09 toolset. I've followed the tutorial to a T and have crosschecked my code to it a million times.

 

When checking the CEGUI log file it returns no error. Heres my log.

 

---- Version 0.7.1 (Build: Jan 27 2010 Microsoft Windows MSVC++ 9.0 32 bit) ----

27/07/2010 15:22:28 (Std) ---- Renderer module is: CEGUI::OpenGLRenderer - Official OpenGL based 2nd generation renderer module. TextureTarget support enabled via FBO extension. ----

27/07/2010 15:22:28 (Std) ---- XML Parser module is: CEGUI::ExpatParser - Official expat based parser module for CEGUI ----

27/07/2010 15:22:28 (Std) ---- Image Codec module is: SILLYImageCodec - Official SILLY based image codec ----

27/07/2010 15:22:28 (Std) ---- Scripting module is: None ----

 

---- CEGUI System initialisation completed ----

27/07/2010 15:22:28 (Std)

27/07/2010 15:22:28 (Std) Started creation of Scheme from XML specification:

27/07/2010 15:22:28 (Std) ---- CEGUI GUIScheme name: TaharezLook

27/07/2010 15:22:28 (Std) Started creation of Imageset from XML specification:

27/07/2010 15:22:28 (Std) ---- CEGUI Imageset name: TaharezLook

27/07/2010 15:22:28 (Std) ---- Source texture file: TaharezLook.tga in resource group: (Default)

 

So I'm rather confused at there being no error in the log for this...

 

I've posted my code below, I left out a lot of the usual leadwerks code in my program but left my comments. Essentially the program stops getting the access violation when the CEGUI code is removed, and when commenting out the aforementioned line I get no crash, but then obviously the GUI doesnt render.

 

 

#include "engine.h"
#include "CEGUI.h" 
#include "RendererModules\OpenGL\CEGUIOpenGLRenderer.h" 
#include "ProcessScene.h"

int main(int argc, char** argv)
{
Initialize();

//Create a graphics context
Graphics(1024,768);

//Create a world
if (!CreateWorld()) 
{
	MessageBoxA(0,"Error","Failed to create world.",0);
	goto exitapp;
}

//Create a camera

//Create a light

       //Load Scene

//Create a render buffer

//Configure Character

//Reposition Camera

//Handle Collisions

//Camera & Movement Variables

//Init GUI
CEGUI::OpenGLRenderer &ceguiRenderer = CEGUI::OpenGLRenderer::create(); 
   CEGUI::System::create(ceguiRenderer);  

   ceguiRenderer.enableExtraStateSettings(true);  

   CEGUI::DefaultResourceProvider *rp = static_cast<CEGUI::DefaultResourceProvider*>(CEGUI::System::getSingleton().getResourceProvider()); 

   rp->setResourceGroupDirectory("schemes", "gui/Schemes/");    
   rp->setResourceGroupDirectory("layouts", "gui/Layouts/");  
   rp->setResourceGroupDirectory("looknfeels", "gui/LookNFeels/");  
   rp->setResourceGroupDirectory("imagesets", "gui/Imagesets/");  
   rp->setResourceGroupDirectory("fonts", "gui/Fonts/");  

   CEGUI::Scheme::setDefaultResourceGroup("schemes");  
   CEGUI::WindowManager::setDefaultResourceGroup("layouts");  
   CEGUI::WidgetLookManager::setDefaultResourceGroup("looknfeels");  
   CEGUI::Imageset::setDefaultResourceGroup("imagesets");  
   CEGUI::Font::setDefaultResourceGroup("fonts");

CEGUI::SchemeManager::getSingleton().create("TaharezLook.scheme");  
   CEGUI::FontManager::getSingleton().create( "DejaVuSans-10.font" );  

   CEGUI::System::getSingleton().setDefaultFont("DejaVuSans-10");  

   CEGUI::WindowManager &wm = CEGUI::WindowManager::getSingleton();  
   CEGUI::Window *root = wm.loadWindowLayout("test.layout");  
   CEGUI::System::getSingleton().setGUISheet(root);

//Main loop
while(!KeyHit(KEY_ESCAPE)) 
{
	//Camera Controls

               //Character Controls

	//Update the world
	UpdateAppTime();
	UpdateWorld();

	//Render the scene
	SetBuffer(buffer);
	RenderWorld();

	//Render lighting
	SetBuffer(BackBuffer());
	RenderLights(buffer);

	//GUI Render
	glPixelStoref(0x806E, 0);  
               glPixelStoref(GL_PACK_ROW_LENGTH, 0);  
              glPixelStoref(GL_UNPACK_ROW_LENGTH, 0);  

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

	Flip();
}
exitapp:
Terminate();
return 0;
}

 

If you need any more information from me please let me know.

 

Thanks in advance =).

Does the same thing happen with the example code posted at the bottom of that tutorial?

 

The only thing I can come up with right now is that you have not set your working directory correctly. It should be the same directory as the command. It my case the command is $(TargetPath) and the working directory is thus set to $(TargetDir).

Its been a few days of tinkering now and I haven't had any luck. I have my command set up properly as well as my working directory. I'm stumped.

I have my files structure set up like this.

 

 

c:\code\CPP_Projects\testproject\

c:\code\CPP_Projects\testproject\source

c:\code\CPP_Projects\testproject\source\Debug

c:\code\CPP_Projects\testproject\GUI

c:\code\CPP_Projects\testproject\media

 

The GUI folder has all the subfolders containing the files for CEGUI, the looksnfeels folder etc.

 

My project settings are like this:

 

*General Settings*

Output Directory: (" ..\ ")

Imtermediate Directory: (" $(Configuration)\ ")

Platform Toolset: v90

 

*Debugging Settings*

Command: (" $(targetpath) ")

Working Directory: (" $(targetdir) ")

 

*C++ General Settings*

Additional Include Directories:

C:\Users\Seraphis\code\Engines\CEGUI\cegui\include;

C:\Users\Seraphis\code\Engines\Leadwerks\CPP;

 

*Linker - Input*

Additional Dependencies:

opengl32.lib

CEGUIBase_d.lib

CEGUIOpenGLRenderer_d.lib

 

Now, inside of c:\code\CPP_Projects\testproject\ rests my EXE along with the following DLLs

 

CEGUIBase_d.dll

CEGUIExpatParser_d.dll

CEGUIFalagardWRBase_d.dll

CEGUIOpenGLRenderer_d.dll

CEGUISillyImageCodec_d.dll

silly_d.dll

 

along with the other dlls needed for the engine.

 

The solution, project file, and all the headers/cpp files are in the source folder.

Hi!

 

I am currently still on holiday but when I get back next monday I will send you a sample VS2010 project to see if it is related to your project settings or something else entirely. Right now I don't see any reason why it shouldn't work.

 

Cheers!

[Seraphis]

I just fixed it, thank god.

 

Thanks for the help anyway man.

[Laurens]

Good to hear, what was the issue?

 

Cheers!

Quite interesting, what was the source of this trouble.
