public class Rotateturret : MonoBehaviour
{
    public enum RotateOnAxis { rotateOnX, rotateOnY, rotateOnZ };
    public bool randomRotation = false;
    [Range(0, 360)]
    public int rotationRange = 70;

    private void Start()
    {

    }

    private void Update()
    {
        if (randomRotation == true)
        {
            var rr = Random.Range(-rotationRange, rotationRange);
            transform.Rotate(Vector3.up, rr);
        }
    }
}

它现在做什么它继续添加或删除旋转的随机数，所以在某些情况下旋转可以是230或450或21它在-70到70的范围内添加/删除但是我希望它添加/删除但是从原始起始位置/旋转只有70 / -70。

例如，如果游戏开始且对象旋转为20，那么添加/删除70，旋转将在20 + 70和20-70之间随机变化，最大可达90，最小为-50。

Answer 1

Rotate将相对于当前轮换行动，因此您实际上在那里累积轮换。试试这个;

Quaternion initialRotation;

void Start ()
{
    // Save initial rotation
    initialRotation = transform.rotation;
}

void Update ()
{
    // Compute random angle in the range of +- rotationRange
    var delta = (Random.value * 2f - 1f) * rotationRange;

    // Compute rotation from the initial rotation and delta
    transform.rotation = initialRotation * Quaternion.Euler(0f, delta, 0f);
}

我相信使用“currentRotation”变量和“startRotation”变量并向其添加随机值将起作用。我在下面的部分中将它添加到您现有的脚本中。

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

public class Rotateturret : MonoBehaviour
{
public enum RotateOnAxis { rotateOnX, rotateOnY, rotateOnZ };
public bool randomRotation = false;
[Range(0, 360)]
public int rotationRange = 70;
public int startRotation = 20; //create a startRotation value.
public int currentRotation = 20; //create a currentRotation value in case you need to access it later.

private void Update()
{
    if (randomRotation == true)
    {
        var rr = Random.Range(-rotationRange, rotationRange);
        currentRotation = startRotation + rr; //Add the random value to the start value. This also works for negative values.
        transform.Rotate(Vector3.up, currentRotation); //use the combined value instead of just rr.
    }
}
}

如何保持对象在原始位置/旋转范围内旋转，而不是每次新旋转时添加/删除？
