Unity使用Input.acceleration旋转Foor

Question

我想使用Input.acceleration旋转floor。如果Input.acceleration接近于零，我想在玩家站立的位置旋转地板，并限制我在某些角度的旋转也停在0。考虑到我在游戏编程新手，我想出了这个代码：

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); 
     } 

    } 
} 

这是工作，但这种方法并不准确，我认为有这样做的更便宜的方法。那么有更好的方法吗？

我想出了这个，我认为这完成了你想要的，尽管我可能误解了你的代码。我已经删除了你的魔术数字，改变了角度以在-180和180之间映射，并将你的变量重命名为具有更好可维护性的全名。

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！
