Assertion failed

[blablub]

I get an assertion failed error on line 73 in CEGUISingleton.h., but I'm using the OGRE singleton template. I wrote my own class that handles all the gui stuff (including CEGUI), which I instantiate once. Throughout the code there's also another non-CEGUI-related class using the Ogre singleton template (if this is important). I used the CEGUI tutorials to set the following up, which then creates the assertion failed...

Code: Select all

template<> Gui* Ogre::Singleton<Gui>::ms_Singleton = 0;

Gui& Gui::getSingleton()
{
    assert(ms_Singleton);
    return(*ms_Singleton);
}

Gui* Gui::getSingletonPtr()
{
    return ms_Singleton;
}

Gui::Gui()
{
    CEGUI::OgreRenderer& mRenderer = CEGUI::OgreRenderer::bootstrapSystem();
    CEGUI::System::create(mRenderer);

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

    rp->setResourceGroupDirectory("schemes", GUI_PATH);
    rp->setResourceGroupDirectory("imagesets", GUI_PATH);
    rp->setResourceGroupDirectory("fonts", GUI_PATH);
    rp->setResourceGroupDirectory("layouts", GUI_PATH);
    rp->setResourceGroupDirectory("looknfeels", GUI_PATH);
    rp->setResourceGroupDirectory("lua_scripts", GUI_PATH);

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

    CEGUI::System::getSingleton().setDefaultMouseCursor("MySkin", "MouseArrow");
    CEGUI::System::getSingleton().setDefaultTooltip("MyTooltip");
    CEGUI::MouseCursor::getSingleton().setImage(
            CEGUI::System::getSingleton().getDefaultMouseCursor());
}

In the cpp I have:

Code: Select all

try
{
    Gui* myGui = new Gui();

    CEGUI::Window* sheet= CEGUI::WindowManager::getSingleton().loadWindowLayout("MyGame.layout");
    CEGUI::System::getSingleton().setGUISheet(sheet);
}
catch (CEGUI::Exception& e)
{
}

Code: Select all

    CEGUI::OgreRenderer& mRenderer = CEGUI::OgreRenderer::bootstrapSystem();
    CEGUI::System::create(mRenderer);


You are creating CEGUI::System twice. bootstrapSystem already creates System for you. Remove the second line and all should be well.

Ah, thanks. Worked fine.

This wasn't completly clear in the tutorials to me.

Edit the tutorials so that it's more clear then please
