Question

我想创造一种效果，就像对象环顾四周。就像在四处巡视。在这种情况下，他正看着窗户，所以想法就是使他看起来像在向外看。

这是Navi看着窗口的屏幕截图：摄像头位于窗口的外面，在Navi面上向前看：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ItemAction : MonoBehaviour
{
    public float xAngle, yAngle, zAngle;
    public float speed;
    public camMouseLook mouselook;
    public GameObject lockedRoomCamera;
    public Camera playerCamera;
    public GameObject navi;
    private bool torotate = false;

    public void Init()
    {
        navi.transform.parent = null;
        navi.transform.localScale = new Vector3(0.5f, 0.5f, 0.5f);
        navi.transform.Rotate(new Vector3(0, 180, 0));
        PlayerController.disablePlayerController = true;
        mouselook.enabled = false;
        playerCamera.enabled = false;
        lockedRoomCamera.SetActive(true);
        torotate = true;

    }

    private void Update()
    {
        if(torotate == true)
        {
            navi.transform.Rotate(xAngle, Random.Range(90, 270) * speed * Time.deltaTime, zAngle, Space.Self);
        }
    }
}

我只想在y轴上随机旋转90度到270度之间的对象。因此，看起来该对象在向左右两侧看。

但是现在对象只是在向左一个方向不停地旋转。

一种方法是使用协程每隔很长时间生成一次随机旋转，然后随时间逐渐变化：

IEnumerator DoLookAround() 
{
    float lookPeriod = 5f; // change look every 5 seconds
    float maxRotationSpeed = 90f; // turn no faster than 90 degrees per second
    Vector3 neutralForward = transform.forward;

    while(true) 
    {
        float timeToNextLook = lookPeriod;

        while (timeToNextLook > 0) {
            // Get random offset from forward
            float targetYRotation = Random.Range(-90f, 90f);

            // calculate target rotation
            Quaternion targetRotation = Quaternion.LookRotation(neutralForward, transform.up) 
                                       * Quaternion.AngleAxis(targetYRotation, Vector3.up);

            // rotate towards target limited by speed
            Quaternion newRotation = Quaternion.RotateTowards(transform.rotation, targetRotation, maxRotationSpeed * Time.deltaTime);


            timeToNextLook -= Time.deltaTime;
            yield return null;
        }
    }
}

然后您可以通过以下方式调用它：

StartCoroutine("DoLookAround");

并用

停止

StopCoroutine("DoLookAround");

如何从y轴上的两个方向随机旋转对象？
