我正在尝试重置库,但我似乎不能。

我找到了这篇文章,但即使有那里的解释,我也无法做到。

在您看到我的代码之前,我要做的是在选项菜单中更改窗口的分辨率。也许有一种我不知道的方法,这是一种矫枉过正。

这就是我正在做的事情(对“渲染器”的引用将它们作为 OpenGL 处理程序):

此代码在 EventHandlerOptions.cpp 中,在函数 ProcessEvent 中

     if(ResolutionChanged)
        {
            // Change the resolution
            Renderer *renderer = GameSettings::GetRenderer();
            GUIScene *gui = GameSettings::GetGUI();
            if(renderer != NULL && gui != NULL)
            {
                bool ok;
                // Shutdown old ones
                gui->Shutdown();
                renderer->Shutdown();

                // Initialize the new ones
                ok = renderer->Init(GameSettings::GetResolutionWidth(), GameSettings::GetResolutionHeight(), 16, (bool)GameSettings::GetRepresentation());
                assert(ok);

                ok = gui->Init(GameSettings::GetResolutionWidth(), GameSettings::GetResolutionHeight());
                assert(ok);
            }
        }

GUI 的相关代码(我正在使用库附带的示例代码,因此您将看到对 Shell 的引用):

bool GUIScene::Init(int width, int height)
{
// Generic OS initialisation, creates a window and attaches OpenGL.
if (!Shell::Initialise("."))
{
    Shell::Shutdown();
    return false;
}

//Rocket initialisation.
Rocket::Core::SetRenderInterface(new ShellRenderInterfaceOpenGL());
Rocket::Core::SetSystemInterface(new ShellSystemInterface());

Rocket::Core::Initialise();
// Initialise the Rocket Controls library.
Rocket::Controls::Initialise();

// Create the main Rocket context and set it on the shell's input layer.
context = Rocket::Core::CreateContext("main", Rocket::Core::Vector2i(width, height));
if (context == NULL)
{
    Rocket::Core::Shutdown();
    Shell::Shutdown();
    return false;
}

Rocket::Debugger::Initialise(context);
Input::SetContext(context);

Shell::LoadFonts("Data/");

// Initialise the event instancer and handlers.
EventInstancer* event_instancer = new EventInstancer();
Rocket::Core::Factory::RegisterEventListenerInstancer(event_instancer);
event_instancer->RemoveReference();


EventManager::SetContext(context);
EventManager::RegisterEventHandler("options", new EventHandlerOptions());


EventManager::LoadWindow("demo");

return true;
}

void GUIScene::Shutdown()
{
// Shutdown Rocket.
EventManager::Shutdown();
context->RemoveReference();
Rocket::Core::Shutdown();

Rocket::Core::SetSystemInterface(NULL);
Rocket::Core::SetRenderInterface(NULL);

Shell::Shutdown();
}

这在 EventManager.cpp 上崩溃(我认为在 ProcessEvent 函数中)

消息是:“Game.exe 中 0x773515de 中的未处理异常:0xC0000005:....位置 0x2ab60ee1”

看起来它与事件管理器有关,但我正在关闭它所以......?

谢谢。
