观看该视频。

我的问题是左，右旋转正常但向上，向下旋转无法正常工作（请参阅视频）。我猜轴问题

那是我的来源

GunObject来源 //缩放

XMMATRIX matScale = XMMatrixIdentity();
    matScale = XMMatrixScaling(m_Scaling.x, m_Scaling.y, m_Scaling.z);

    // rotation
    XMMATRIX matRoation = XMMatrixIdentity();
    matRoation *= XMMatrixRotationNormal(XMLoadFloat3(&XMFLOAT3(0.0f, 1.0f, 0.0f)), m_fRotAngleY);
    matRoation *= XMMatrixRotationNormal(XMLoadFloat3(&vRight), m_fRotAngleX);

    // Translate
    XMMATRIX matTranslate = XMMatrixIdentity();
    matTranslate = XMMatrixTranslation(m_Pos.x, m_Pos.y, m_Pos.z);

    XMMATRIX matWorld = XMMatrixIdentity();
    matWorld = matScale * matRoation * matTranslate;

    XMStoreFloat4x4(&m_f4x4World, matWorld);
    XMStoreFloat4x4(&m_f4x4ViewProj, matViewProj);
    XMStoreFloat4x4(&m_f4x4WorldViewProj, matWorld * matViewProj);
