Gyroscope.rotationRate

설명

Returns rotation rate as measured by the device's gyroscope.

The rotation rate is given as a Vector3 representing the speed of rotation around each of the three axes in radians per second. This is the value as it is reported by the gyroscope hardware - a more accurate measurement that has been processed to remove "bias" can be obtained with the rotationRateUnbiased property.

    void Start()
    {
        audioSource = GetComponent<AudioSource>();
    }

    void Update()
    {
        if (Input.gyro.rotationRate.y > shakeSpeed &amp;&amp; !audioSource.isPlaying)
            audioSource.PlayOneShot(shakeSound);
    }
