Google Cardboard Magnet Refresh Not Working in Unity3d - unity3d

Question

I am working on a Unity project using google cardboard, basing my design on Cardboard Catapult, cardboard magnet to make a ball jump and it works the first time, but whenever the game restarts, using Application.LoadLevel(), the ball doesn’t jump anymore; it just glitches. I used this script. I have tested this script (Magnet Sensor Script) with a test application where whenever the magnet is pulled, the text will change color and it works all the time. Here’s my Ball Control Script (the script I called the Magnet Sensing):
#pragma strict
var rotationSpeed = 100;
var jumpHeight = 8;
var Hit01 : AudioClip;
var Hit02 : AudioClip;
var Hit03 : AudioClip;
var distToGround : float;
function Start () {
// Getting the distance from the center to the ground.
distToGround = collider.bounds.extents.y;
}
function Update ()
{
//Handle ball rotation.
var rotation : float = Input.GetAxis(“Horizontal”) * rotationSpeed;
rotation *= Time.deltaTime;
rigidbody.AddRelativeTorque (Vector3.back * rotation);
MagnetSensor.OnMagnetPull += JumpOnMagnet; //important
}
function JumpOnMagnet () { //important
rigidbody.velocity.y = jumpHeight; //important
} //important
function IsGrounded () : boolean { //Check if we are on the ground. Return true if we are else return null.
return Physics.Raycast(transform.position, -Vector3.up, distToGround + 0.1);
}
function OnCollisionEnter () {
var theHit = Random.Range(0, 3);
if (theHit == 0)
{
audio.clip = Hit01;
}
else if (theHit == 1)
{
audio.clip = Hit02;
}
else {
audio.clip = Hit03;
}
audio.pitch = Random.Range (0.9,1.1);
audio.Play();
}
Here’s my script for the restart:
#pragma strict
var maxFallDistance = -10;
private var isRestarting = false;
var level : String;
var GameOverSound : AudioClip;
function Update ()
{
if (transform.position.y <= maxFallDistance)
{
if (isRestarting == false)
{
RestartLevel();
}
}
}
function RestartLevel () {
isRestarting = true;
audio.pitch = 1;
audio.clip = GameOverSound;
audio.Play();
yield WaitForSeconds (audio.clip.length);
Application.LoadLevel(level);
}
Please let me know what the possible issues could be and how I can fix them. Also, I’d appreciate if you can point me to any website or resource that can help.

Don't do MagnetSensor.OnMagnetPull += JumpOnMagnet; in the Update() function. Call it in Start(), so it is only added once.
Also, you should add an OnDestroy() function and call MagnetSensor.OnMagnetPull -= JumpOnMagnet; in it.
