Input.acceleration

Description

Last measured linear acceleration of a device in three-dimensional space. (Read Only)

Note: This API is part of the legacy Input class, and not recommended for new projects. The documentation is provided here to support legacy projects that use the old Input Manager and Input class. For new projects you should use the newer and Input System Package. (read more).

using UnityEngine;

public class Example : MonoBehaviour
{
    // Move object using accelerometer
    float speed = 10.0f;

    void Update()
    {
        Vector3 dir = 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.x = -Input.acceleration.y;
        dir.z = Input.acceleration.x;

        // clamp acceleration vector to unit sphere
        if (dir.sqrMagnitude > 1)
            dir.Normalize();

        // Make it move 10 meters per second instead of 10 meters per frame...
        dir *= Time.deltaTime;

        // Move object
        transform.Translate(dir * speed);
    }
