gyroscope won't work on iOS,gyroscope.attitude not working on iOS
Hello.
I am having an issue with gyroscope and iOS. I am making a VR game and for simple head movement i use this code
public Quaternion attitude;
void Start () {
Input.gyro.enabled = true;
}
void Update () {
attitude = Input.gyro.attitude;
transform.localRotation.Set(attitude.x, attitude.y, attitude.z, attitude.w);
}
The issue is that on iOS this code will not rotate the object it is on. It works Android without issue, as such i first expected an issue with permissions. Thus i tested by printing out the 4 quaterion values of attitude on GUI elements and the game has full access. For good measure i tried including extra permissions for both NS Motion and the Health Care functions of iOS in Xcode without any sucess.
From what i can discern it seems to be the transform.localRotation.Set() function that is not working as i can read the values. I can even access the attitude.eulerAngles and utilize them, but they quickly cause issues as the roation gets skewed and distorted in unwanted ways. I have also utilized the Rotate() function, setPositionAndRoation() function as well as attempting to convert the eulerAngles back into quaternion. The latter is said in the Unity Documentation to cause problems.
I am out of ideas or solutions. Is this issue with the Set() function a bug? am i missing some sort of function? Has anyone had similar issues?
I have Unity 2017.3.0f3, Xcode 9.3 and I have tested on iPhone 7, two iPhone SE (just in case) and an iPhone 6 and a bunch of Androids.
Any help is very much appriciated?
I have found a work around. I convert each of the Quaternion floats to seperate floats in code and apply them to the transform.rotation as a new Quaternion. Rotation.Set still does not work
void SetRotation(float x, float y, float z, float w)
{
transform.rotation = new Quaternion(x,y,z,w);
}
