Check if compass sensor available?

Unity Engine

Hi,
How can I check to see if the device has a compass?

Thanks

This seems to work: Try setting and reading Input.compass.enabled. If you enable it but it still read false, there’s no compass.

Thanks, will give this a go

Reading Input.compass.enabled is not working for me (at least not on my iPhone).

I’m not sure how accurate this is, but here’s what I did:

private IEnumerator IsCompassAvailable () {
    bool compass = false;

    for (int i = 0; i < 10; i++) {
        if (Input.compass.trueHeading != 0) {
            compass = true;
        }

        yield return new WaitForSeconds(0.05f);
    }
       
    yield return compass;
}

Basically I take 10 samples of the sensor across 500ms, if they are all equal to 0 I assume that there is no compass available (this probably works with magneticHeading too).
Obviously you need to enable the compass beforehand.

I hope this helps someone!
