Minor issue with a VR head tracking script to control the camera?
Hello,
INTRO :
I have a head tracking script for VR to rotate around. It is placed on the Camera GameObject & is sole purpose is to rotate the camera in accordance to the rotation of the head.
ISSUE: The script woks fine but it looks like the rotation is inverted.
Target :
Mobile device (let's say iOS & Android)
REQUEST:
I think I am making a mistake with the math functions.
Here is the script :
using UnityEngine;
using System.Collections;
public class HeadTrack : MonoBehaviour
{
private bool gyroBool;
private Gyroscope gyro;
private Quaternion rotFix;
private Vector3 initial = new Vector3(90, 180, 0);
// Use this for initialization
void Start()
{
Screen.orientation = ScreenOrientation.LandscapeLeft;
Screen.sleepTimeout = SleepTimeout.NeverSleep;
gyroBool = SystemInfo.supportsGyroscope;
Debug.Log("gyro bool = " + gyroBool.ToString());
if (gyroBool)
{
gyro = Input.gyro;
gyro.enabled = true;
rotFix = new Quaternion(0, 0, 0.7071f, 0.7071f);
}
else
{
Debug.Log("No Gyro Support");
}
}
// Update is called once per frame
void Update()
{
if (gyroBool)
{
var camRot = gyro.attitude * rotFix;
transform.eulerAngles = initial;
transform.localRotation *= camRot;
}
}
}
If anyone could point me in the right direction, I would much appreciate it.
regards, Karsnen.
