Rotate Object by Tilting Android Device Any Angle

@$$anonymous$$wahuNashoba Thank you for the help :)

But, I couldn't get it to work. The object is not moving at all. Any ideas?

It looks like for Android people use Input.acceleration ins$$anonymous$$d of input.gyro. what do you think? http://answers.unity3d.com/questions/254111/how-to-enable-the-gyroscope-for-input-on-an-androi.html

I attached the script to the object that I want to rotate and changed the script so that there won't be any compile errors, so this is the exact script:

using UnityEngine; using System.Collections;

 public class AndroidInputControllerC : $$anonymous$$onoBehaviour {
 
     // Use this for initialization
     void Start () {

         if(!Input.gyro.enabled)
         {
             Input.gyro.enabled = true;
         }
     }
     
     // Update is called once per frame
     void Update () 
     {
         transform.rotation  = Input.gyro.attitude;
     }
 }

3 . The following code works but has two issues. a) it is too sensitive. the object is constantly shaking and when rotating the object it rotates really shaky. b) when tilting the Android device from parallel-to-ground-face-up state to parallel-to-ground-face-down state, the object makes a whole rotation of 360 degrees, while it should be rotating only 180 degrees like the Android device. Another example: when tilting the Android device from parallel-to-ground-face-up state to horizontal state (when it's facing your face), the object turns 180 degrees ins$$anonymous$$d of 90 degrees.

 var rotx : float = 0;
 var roty : float = 0;
 var rotz : float = 0;
 var rotw : float = 0;
 
 function Start() {
     Screen.orientation = ScreenOrientation.LandscapeLeft;
 }
 
 function Update () {
     rotx = Input.acceleration.x;
     roty = Input.acceleration.y;
     rotz = Input.acceleration.z;
     transform.rotation = new Quaternion(rotx, roty, rotz, rotw);
 }

Below are three different code-snippets I have tried that all work in different ways but each have different problems. $$anonymous$$aybe this can help someone to solve it. If anyone find a solution using this info, please post the solution because I'm stuck on this for a long time already.

1. This following code works but has two problems.

a) It moved constantly ins$$anonymous$$d of stopping the object when the android is stopped. What is needed is that when the Android device is tilted left, the object will tilt left and then stop when the Android device is stopped. But the way this code works is that the object only stops moving when the Android device is help face up parallel to the ground.

b) When the object is tilted a certain direction then it changes the other directions tilting on. So if tilting on X axis then Y axis will title from where the object has been rotated so it actually won't be rotating on Y anymore. So ins$$anonymous$$d of tilting Y and the object rotating on Y, the object will no longer rotate on Y because the direction of the object has changed. What is needed that the object rotates the direction the Android device is tilted regardless of which direction the object is pointing because of previous rotation.

     var speed = 10.0;
     
     function Start() {
         Screen.orientation = ScreenOrientation.LandscapeLeft;
     }
     
     function Update () {
         var dir : Vector3 = Vector3.zero;
     
         // we assume that device is held parallel to the ground
         // and Home button is in the right hand
         
         // remap device acceleration axis to game coordinates:
         //  1) XY plane of the device is mapped onto XZ plane
         //  2) rotated 90 degrees around Y axis
         dir.y = -Input.acceleration.x;
         dir.z = Input.acceleration.y;
         
         // clamp acceleration vector to unit sphere
         if (dir.sqr$$anonymous$$agnitude > 1)
             dir.Normalize();
         
         // $$anonymous$$ake it move 10 meters per second ins$$anonymous$$d of 10 meters per frame...
         dir *= Time.deltaTime;
             
         transform.Rotate (dir * speed);
     }

The other two code snippets are in the next two comment because of character limit of the post.

2 . The following code works but has one problem: When the Android device is held face up parallel to the ground, when tilting the Android device left/right, the object rotates with a diagonal shift ins$$anonymous$$d of just rotating right/left. Also, when holding the Android device upside-down facing your face then it doesn't rotate the object well. This code works well only when the Android device is facing your face (not when help up parallel to ground or when held upside down facing your face).

     private var sizeFilter: int = 15;
     private var filter: Vector3[];
     private var filterSum = Vector3.zero;
     private var posFilter: int = 0;
     private var qSamples: int = 0;
     
     function Start() {
         Screen.orientation = ScreenOrientation.LandscapeLeft;
     }
     
     function $$anonymous$$ovAverage(sample: Vector3): Vector3 {
          if (qSamples==0) filter = new Vector3[sizeFilter];
          filterSum += sample - filter[posFilter];
          filter[posFilter++] = sample;
          if (posFilter > qSamples) qSamples = posFilter;
          posFilter = posFilter % sizeFilter;
          return filterSum / qSamples;
     }
     
     function Update () {
         transform.up = -$$anonymous$$ovAverage(Input.acceleration.normalized);
     }
