Reset Accelerometer? Is it possible?

I just ended up putting the FixAcceleration function in the control script and it was much easier to access.

 

Thanks Fuel Games guys and Little Angel - I need to calibrate the accelerometer and had no idea how to do it. I dropped your script into my Game Engine and my UI HUD controller... literally 5 minutes later, it's perfect. I cannot say thank you enough around here - Unity FTW : )

 

I've posted my simplified calibration code from this thread here:

Thanks cheezorg. If you are still around on these forums I appreciate your solution. This works great.

 

I realize this thread is kind of old but I'm having difficulties getting the "fix" from Fuel Games to work with my existing script (Sorry there's a bunch of logic in there to find platform and requested input type). I suspect its where I'm trying to get the calibrated vaue but I'm not sure. Normally I write in Unity.js so it could also be my C# translation skills aren't up to the task.

At any rate any help would be appreciated, thanks in advance!

Code (csharp):

1.  
2.     void calibrateAccelerometer() {
3.         Vector3 wantedDeadZone = iPhoneInput.acceleration;
4.         Quaternion rotateQuaternion = Quaternion.FromToRotation(new Vector3(0f, 0f, -1f), wantedDeadZone);
5.    
6.         //create identity matrix ... rotate our matrix to match up with down vec
7.         Matrix4x4 matrix = Matrix4x4.TRS(Vector3.zero, rotateQuaternion, new Vector3(1f, 1f, 1f));
8.         //get the inverse of the matrix
9.         this.calibrationMatrix = matrix.inverse;
10.     }
11.    
12.     Vector3 getAccelerometer(Vector3 accelerator) {
13.         Vector3 accel = this.calibrationMatrix.MultiplyVector(accelerator);
14.         return accel;
15.     }
16.    
17.    
18.     void Update ()
19.     {  
20.         Vector3 forward = Camera.main.transform.TransformDirection(Vector3.forward);
21.         forward.y = 0;
22.         forward = forward.normalized;
23.        
24.         Vector3 forwardForce = new Vector3();
25.        
26.         if (Application.platform == RuntimePlatform.IPhonePlayer || Application.platform == RuntimePlatform.Android)
27.         {
28.             if(tiltControls == 0) {
29.                 //tilt off
30.                 float tmpSpeed = moveJoy.GetComponent<Joystick>().position.y;
31.                 forwardForce = forward * tmpSpeed * 1f * moveSpeed;
32.             } else {
33.                 //tilt on
34.                 float tmpSpeed = Input.acceleration.y *8;              
35.                 forwardForce = forward * tmpSpeed * 1f * moveSpeed;
36.                 getAccelerometer(forwardForce);
37.             }  
38.            
39.         }
40.         else
41.         {
42.             forwardForce = forward * Input.GetAxis("Vertical") * moveSpeed;
43.         }
44.         rigidbody.AddForce(forwardForce);

As in my case execute calibration, week I am puzzled with this question, helps nothing.

Code (CSharp):

1.  void Start () {
2.      mainCamera = Camera.main.transform;
3.      thisRigidbody = GetComponent<Rigidbody>();
4. }
5. void Update () {
6.  
7.      float h = (Input.acceleration.x);
8.      float v = (-Input.acceleration.z);
9.    
10.      if (mainCamera != null)
11.      {
12.          mainCameraForward = Vector3.Scale (mainCamera.forward, new Vector3 (1, 0, 1));
13.          move = (v * mainCameraForward + h * mainCamera.right);
14.      }
15.      else
16.      {
17.          move = (v * Vector3.forward + h * Vector3.right);
18.      }
19.      if (useTorque)
20.      {
21.          thisRigidbody.AddTorque(new Vector3(move.z, 0, -move.x) * moveSpeed);
22.      }
23.      else
24.      {
25.          thisRigidbody.AddForce(move * moveSpeed);
26.      }
27. }

 

Hi,

sorry for Necro posting, but I can't adapt this code to my needs :
Here, I want to change the Physics.gravity with the accelerometer (for a classic Roll-a-ball game). Here's what I've tried :

Code (CSharp):

1.     void Start(){
2.  
3.         GravityStart = new Vector3 (
4.             Mathf.Clamp (Input.acceleration.x, -1, 1),
5.             Mathf.Clamp (Input.acceleration.z, -0.05f, 0.05f),
6.             Mathf.Clamp (Input.acceleration.y, -1, 1)
7.         ) * g;
8.         Quaternion rotateQ = Quaternion.FromToRotation (new Vector3 (0f, 0f, -1f), GravityStart);
9.         Matrix4x4 matrix = Matrix4x4.TRS (Vector3.zero, rotateQ, new Vector3 (1f, 1f, 1f));
10.         this.calibrationMatrix = matrix.inverse;
11.     }
12.  
13.     Vector3 getAccelerometer(Vector3 accelerator){
14.         Vector3 accel = this.calibrationMatrix.MultiplyVector (accelerator);
15.         return accel;
16.     }
17.     void Update() {
18.         // normalize axis
19.         Physics.gravity = new Vector3 (
20.             Mathf.Clamp (Input.acceleration.x, -1, 1),
21.             Mathf.Clamp (Input.acceleration.z, -0.05f, 0.05f),
22.             Mathf.Clamp (Input.acceleration.y, -1, 1)
23.         ) * g;
24. Physics.gravity=getAccelerometer(Physics.gravity);
25. }

Has anyone an idea ?
all the best,
L.
