hi guys i have a problem with my player(Roll A Ball Game) on android, my player easily move left, right, up, down But when i tilt my phone to move player up it's too slow

using UnityEngine; using System.Collections; [RequireComponent(typeof(Rigidbody))] public class ForceFromAccelerometer : MonoBehaviour { // gravity constant public float g=9.8f; void FixedUpdate() { // normalize axis var gravity = new Vector3 ( Input.acceleration.x, Input.acceleration.z, Input.acceleration.y ) * g; GetComponent().AddForce (gravity, ForceMode.Acceleration); } }
