Question

我正在制作飞机游戏，我需要获得飞机的偏航。下面是设置俯仰和滚动的工作代码，但我无法弄清楚偏航。

private void _CalculateRollAndPitchAngles()
{
    // Calculate roll & pitch angles
    // Calculate the flat forward direction (with no y component).
    Vector3 flatForward = transform.forward;
    flatForward.y = 0;
    // If the flat forward vector is non-zero (which would only happen if the plane was pointing exactly straight upwards)
    if (flatForward.sqrMagnitude > 0)
    {
        flatForward.Normalize();
        // calculate current pitch angle
        Vector3 localFlatForward = transform.InverseTransformDirection(flatForward);
        m_pitchDegrees = Mathf.Atan2(localFlatForward.y, localFlatForward.z) * Mathf.Rad2Deg;
        // calculate current roll angle
        Vector3 flatRight = Vector3.Cross(Vector3.up, flatForward);
        Vector3 localFlatRight = transform.InverseTransformDirection(flatRight);
        m_rollDegrees = Mathf.Atan2(localFlatRight.y, localFlatRight.x) * Mathf.Rad2Deg;
    }
}

继续评论之后，您可以使用here中的公式并将Y-Z交换计算出来，将转换矩阵（或其旋转部分）直接转换为欧拉角：

roll = atan2(M[1][2], M[1][1])
pitch = atan2(-M[1][0], sqrt(M[0][1] * M[0][1] + M[0][0] * M[0][0]))
yaw = atan2(M[2][0], M[0][0])

如何从Unity中的变换获得偏航度？
