我正在尝试使用 Input.acceleration 旋转地板。如果 Input.acceleration 接近于零，我想围绕玩家站立的点旋转地板并限制我在某些角度的旋转也停止在 0。考虑到我是游戏编程的新手，我想出了以下代码：

using UnityEngine;
using System.Collections;

public class Tilt : MonoBehaviour {

    public float maxRotationAngle = 350;                    // max rotation right
    public float minRotationAngle = 10;                     // max rotation left 
    public float rotationSpeed = 20;                        //rotation speed
    public Transform rotateAround;                          //rotation point
    private bool stopRotation = false;                      //if this is true rotation stops
    private int stopDir;                                    //direction where rotation stops -1 equals left 0 center 1 right

    void Update () {

        int tiltDir = 0;                                    //input tilt direction
        float accel = Input.acceleration.x;                 //input tilt value
        float currentRotation = transform.eulerAngles.z;    //current rotation

        //set rotation direction
        if (accel > 0) {
            tiltDir = 1;
        }else if (accel < 0){
            tiltDir = -1;
        }

        //stop rotation left
        if (!stopRotation && (currentRotation < maxRotationAngle && currentRotation > 270)) {
            stopRotation = true;
            stopDir = -1;
        }
        //stop rotation right
        if (!stopRotation && (currentRotation > minRotationAngle && currentRotation < 270)) {
            stopRotation = true;
            stopDir = 1;
        }
        //allow rotation right
        if (stopRotation && stopDir < 0 && Input.acceleration.x > 0) {
            stopRotation = false;

        }
        //allow rotation left
        if (stopRotation && stopDir > 0 && Input.acceleration.x < 0) {
            stopRotation = false;
        }
        //stop rotation center
        if(!stopRotation  && currentRotation < 0.2 || (currentRotation > 359.8 && currentRotation < 360)){
            if(accel > -0.1 && accel < 0.1){
                stopRotation = true;
                stopDir = 0;
            }
        }
        //allow rotation from center
        if(stopRotation && stopDir == 0 && (accel < -0.1 || accel > 0.1)){
            stopRotation = false;
        }
        //apply rotation
        if(!stopRotation){
            transform.RotateAround(rotateAround.position, new Vector3(0, 0, tiltDir), rotationSpeed * Mathf.Abs(accel) * Time.deltaTime);
        }

    }
}

这是可行的，但这种方法并不准确，我认为有更便宜的方法可以做到这一点。那么有没有更好的方法呢？

我想出了这个，我认为它可以实现你想要的，尽管我可能误读了你的代码。我已经删除了您的幻数，将角度更改为 -180 到 180 之间的映射，并将您的变量重命名为具有全名以获得更好的可维护性。

public float maxRotationAngle = 170;
public float minRotationAngle = -170;
public float minimumAcceleration = 0.1f;
public float rotationSpeed = 20;
public Transform rotateAroundTransform;

void Update () 
{
    float deltaAcceleration = Mathf.Abs(Input.acceleration.x);
    float currentRotation = transform.eulerAngles.z;

    //stop rotation outside of angle range and motion range
    if (currentRotation > minRotationAngle && 
        currentRotation < maxRotationAngle && 
        deltaAcceleration < minimumAcceleration) 
    {
        //set rotation direction
        int tiltDirection = Input.acceleration.x > 0 ? 1 : -1;
        transform.RotateAround(rotateAroundTransform.position, new Vector3(0, 0, tiltDirection), rotationSpeed * deltaAcceleration * Time.deltaTime);
    }
}

希望有帮助！
