Directx11教程(11) 增加一个debug宏

      现在我们在common.h中增加一个debug的宏,在每个d3d11函数后调用,如果d3d函数出错,它能够给出程序中错误的代码行数。

common.h代码如下:

#pragma once

#include <d3d11.h>
#include <d3dx10math.h>

#if defined(DEBUG) || defined(_DEBUG)
#ifndef D3D_DEBUG_INFO
#define D3D_DEBUG_INFO
#endif
#endif

#if defined(DEBUG) || defined(_DEBUG)
#define _CRTDBG_MAP_ALLOC
#include <crtdbg.h>
#endif

#include <dxerr.h>
#include <cassert>

//一个简单的错误检测宏

#if defined(DEBUG) | defined(_DEBUG)
    #ifndef HR
    #define HR(x)                                              \
    {                                                          \
        HRESULT hr = (x);                                      \
        if(FAILED(hr))                                         \
        {                                                      \
            DXTrace(__FILE__, (DWORD)__LINE__, hr, L#x, true); \
        }                                                      \
    }
    #endif

#else
    #ifndef HR
    #define HR(x) (x)
    #endif
#endif

//定义一些常用颜色
const D3DXVECTOR4 WHITE(1.0f, 1.0f, 1.0f, 1.0f);
const D3DXVECTOR4 BLACK(0.0f, 0.0f, 0.0f, 1.0f);
const D3DXVECTOR4 RED(1.0f, 0.0f, 0.0f, 1.0f);
const D3DXVECTOR4 GREEN(0.0f, 1.0f, 0.0f, 1.0f);
const D3DXVECTOR4 BLUE(0.0f, 0.0f, 1.0f, 1.0f);
const D3DXVECTOR4 YELLOW(1.0f, 1.0f, 0.0f, 1.0f);
const D3DXVECTOR4 CYAN(0.0f, 1.0f, 1.0f, 1.0f); //蓝绿色
const D3DXVECTOR4 MAGENTA(1.0f, 0.0f, 1.0f, 1.0f);//洋红色

const D3DXVECTOR4 BEACH_SAND(1.0f, 0.96f, 0.62f, 1.0f);
const D3DXVECTOR4 LIGHT_YELLOW_GREEN(0.48f, 0.77f, 0.46f, 1.0f);
const D3DXVECTOR4 DARK_YELLOW_GREEN(0.1f, 0.48f, 0.19f, 1.0f);
const D3DXVECTOR4 DARKBROWN(0.45f, 0.39f, 0.34f, 1.0f);

 

现在我们修改每一个D3D11函数的调用,比如

// 创建交换链,设备以及设备上下文.
result = D3D11CreateDeviceAndSwapChain(NULL, D3D_DRIVER_TYPE_HARDWARE, NULL,createDeviceFlags, &featureLevel, 1,
    D3D11_SDK_VERSION, &swapChainDesc, &m_swapChain, &m_device, NULL, &m_deviceContext);
if(FAILED(result))
    {
    HR(result);
    return false;
    }
其它类似的代码我就不贴了。
