My accelerometer input works fine through Unity remote, but doesn't work when I build on ios

Hey guys,

My accelerometer input works fine when I run my game through Unity remote, but doesn't work when I build it through XCode and run it on my iPhone that way. I have already checked when I built my game my accelerometer frequency was set to 60Hz but it still doesn't work.

Here is my code, any help is highly appreciated!

Code (CSharp):

1.     void AcceleratorMove()
2.     {
3.         float x = Input.acceleration.x;
4.         if (x<-0.1f)
5.         {
6.             MoveLeft();
7.         }
8.         else if (x > 0.1f)
9.         {
10.             MoveRight();
11.         }
12.         else
13.         {
14.             SetVelocityZero();
15.         }
16.  
17.     }
18.      void MoveLeft()
19.     {
20.         position.x += -1 * Time.deltaTime * horizontalPositionSpeedMultiplier;
21.     }
22.     void MoveRight()
23.     {
24.         position.x += 1 * Time.deltaTime * horizontalPositionSpeedMultiplier;
25.     }
26.     void SetVelocityZero()
27.     {
28.         position.x += 0 * Time.deltaTime * horizontalPositionSpeedMultiplier;
29.     }

 

There is no problem in your code. If you set the accelerometer frequency in the build settings correctly (which you said you did), I guess there might be a #if UNITY_EDITOR code snippet or an EditorOnly tag on a game object so the script won't be executed in a build. Maybe post thhe complete script so we can dissect it further.

 

Ok thanks. So this is my full code. Please let me know what you think?

The error is at line 88. You're overwriting your just calculated position with transform.position. This is no problem for standalone since there you're also setting the transform.position value. I suggest moving line 88 to the start of the update method.

 

Thank you, you are an absolute genius!!! The problem is solved. thank you
