在第三人称模式下，让物体也能够进行前后、左右的平移运动

//修改代码片段
    else if (m_CameraMode == CameraMode::ThirdPerson)
 {
     // 第三人称摄像机的操作

     cam3rd->SetTarget(woodCrateTransform.GetPosition());

     // 绕物体旋转
     cam3rd->RotateX(mouseState.y * dt * 2.5f);
     cam3rd->RotateY(mouseState.x * dt * 2.5f);
     cam3rd->Approach(-mouseState.scrollWheelValue / 120 * 1.0f);
     if (keyState.IsKeyDown(Keyboard::W)) {
         woodCrateTransform.Translate(XMFLOAT3(0.0f,0.0f,1.0f), dt * 0.6f);
     }
     if (keyState.IsKeyDown(Keyboard::S)) {
         woodCrateTransform.Translate(XMFLOAT3(0.0f, 0.0f, -1.0f), dt * 0.6f);
     }
     if (keyState.IsKeyDown(Keyboard::A)) {
         woodCrateTransform.Translate(XMFLOAT3(-1.0f, 0.0f, 0.0f), dt * 0.6f);
     }
     if (keyState.IsKeyDown(Keyboard::D)) {

         woodCrateTransform.Translate(XMFLOAT3(1.0f, 0.0f, 0.0f), dt * 0.6f);
     }
 }

在第三人称模式下，使用平躺的圆柱体，让其左右平移运动改为左右旋转运动，前后运动改为朝前滚动

// 切换 第三人称时改变物体
 ComPtr<ID3D11ShaderResourceView> texture;
 // 初始化圆柱
 HR(CreateDDSTextureFromFile(m_pd3dDevice.Get(), L"..\\Texture\\WoodCrate.dds", nullptr, texture.GetAddressOf()));
 m_WoodCrate.SetBuffer(m_pd3dDevice.Get(), Geometry::CreateCylinder());
 m_WoodCrate.SetTexture(texture.Get());
 Transform&  wTransform = m_WoodCrate.GetTransform();
 wTransform.SetRotation(0.5f * 3.1415926f, 0.0f, 0.0f);
 //修改代码
 else if (m_CameraMode == CameraMode::ThirdPerson)
 {
     // 第三人称摄像机的操作

     cam3rd->SetTarget(woodCrateTransform.GetPosition());

     // 绕物体旋转
     cam3rd->RotateX(mouseState.y * dt * 2.5f);
     cam3rd->RotateY(mouseState.x * dt * 2.5f);
     cam3rd->Approach(-mouseState.scrollWheelValue / 120 * 1.0f);
     if (keyState.IsKeyDown(Keyboard::W)) {
         woodCrateTransform.Translate(XMFLOAT3(0.0f,0.0f,1.0f), dt * 0.6f);
         woodCrateTransform.RotateAxis(XMFLOAT3(1.0f, 0.0f, 0.0f), -dt * 0.6f * 3.1415926f);
     }
     if (keyState.IsKeyDown(Keyboard::S)) {
         woodCrateTransform.Translate(XMFLOAT3(0.0f, 0.0f, -1.0f), dt * 0.6f);
         woodCrateTransform.RotateAxis(XMFLOAT3(1.0f, 0.0f, 0.0f), dt * 0.6f * 3.1415926f);
     }
     if (keyState.IsKeyDown(Keyboard::A)) {
         woodCrateTransform.Translate(XMFLOAT3(-1.0f, 0.0f, 0.0f), dt * 0.6f);
         woodCrateTransform.RotateAxis(XMFLOAT3(0.0f, 0.0f, 1.0f), dt * 0.6f * 3.1415926f);
     }
     if (keyState.IsKeyDown(Keyboard::D)) {
         woodCrateTransform.Translate(XMFLOAT3(1.0f, 0.0f, 0.0f), dt * 0.6f);
         woodCrateTransform.RotateAxis(XMFLOAT3(0.0f, 0.0f, 1.0f), -dt * 0.6f * 3.1415926f);
     }
 }
