推荐答案

您可以使用内置物理学来做到这一点：

You can do this with builtin physics:

1. 用一些简单的可缩放立方体创建一个关卡（不要忘记地面）。

1. 添加球-一个球体，然后添加 RigidBody 。在刚体上设置一个约束-检查冻结位置y（如果将设备倒置，它会跳出水平位置。）。

1. add the ball - a sphere, then and add a RigidBody to it. Set a constraint on the rigidbody - check freeze position y (or it will be able to jump out of the level if you put the device upside down).

将此脚本添加到场景中的任何位置（例如，添加到摄像机）：

add this script anywhere on the scene (for example to the camera):

using UnityEngine;

public class GravityFromAccelerometer : MonoBehaviour {

    // gravity constant
    public float g=9.8f;

    void Update() {
        // normalize axis
        Physics.gravity=new Vector3(
            Input.acceleration.x,
            Input.acceleration.z,
            Input.acceleration.y
        )*g;
    }

}

或者如果您希望物理学只是影响这个对象，将此脚本添加到该对象并关闭它受重力影响的刚体：

or if you want the physics to just affect this one object, add this script to the object and turn off it's rigidbody's affected by gravity:

using UnityEngine;

[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<Rigidbody>().AddForce (gravity, ForceMode.Acceleration);
    }

}

现在您有了工作球物理。要使球表现出所需的效果，请尝试使用刚体属性。例如，将阻力更改为0.1。

And now you have working ball physics. To make the ball behave as you'd like, try to play with the rigidbody properties. For example, change the drag to something like 0.1.
