1. 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);
        }
    }

2. 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);
        }
    }

3. 尝试实现带有父子关系的Transform变换和GameObject

   放弃
