Toggle between Touch input and accelerometer

Hi everyone,

I'm building a variation of the Space Shooter project for mobile and I want to implement an options menu toggle to change from accelerometer controls to touch based controls for the player ship.

I have already implemented both controls and I was thinking to use PlayerPrefs to make the change constant though out the different playthroughs, but I can't get it to work.

Here is a sample code of what I'm doing inside the Player controller:

 void Start () 
     {
         CalibrateAccelerometer ();
         GameObject gameControllerObject = GameObject.FindGameObjectWithTag ("GameController");
         if (gameControllerObject != null)
         {
             gameController = gameControllerObject.GetComponent <Done_GameController>();
         }
         if (gameController == null)
         {
             Debug.Log ("Cannot find 'GameController' script");
         }
         
         touchControls = gameController.state;
         
         Debug.Log ("Are touch controls on? " + touchControls); 
     }

Here is what I do inside the Fixed Update of the same Player controller to choose between different inputs:

 if (touchControls == 0) {
             //Acceleration controls
             Vector3 accelerationRaw = Input.acceleration;
             Vector3 acceleration = FixAcceleration (accelerationRaw);
             movement = new Vector3 (acceleration.x, 0.0f, acceleration.y);
         }
 
         if (touchControls == 1) {
             //Touch Controls
             Vector2 direction = touchPad.GetDirection ();
             movement = new Vector3 (direction.x, 0.0f, direction.y);
         }

Now on the Gamecontroller script to set toggle options on Accelerometer controls or Touch input controls I call the following methods in the toggle options:

     public void SetTouchContols () {
         PlayerPrefs.SetInt(TouchControlsKey, 1);
         state = PlayerPrefs.GetInt(TouchControlsKey, 1);
         Debug.Log ("Touch controls value: " + state);
         PlayerPrefs.Save();
     }
     public void SetAccelerometerControls () {
         PlayerPrefs.SetInt(TouchControlsKey, 0);
         state = PlayerPrefs.GetInt(TouchControlsKey, 0);
         Debug.Log ("Touch controls value: " + state);
         PlayerPrefs.Save();
     }

Finally here is an image of how I hooked up the toggle group:

I can't manage to get it to work properly and i tried different approaches. I ‘have heard the controls can't be changed on runtime but if the change was made in another scene (e.g. Main menu Scene) could it be done?

Thanks! :)
