Unity 扩散式布局

如图所示，可以随意增加数量，半径，起始角度和终止角度等。

代码使用Dotween，如有报错，还请检查是否引入了该组件

代码如下：

using UnityEngine;
using DG.Tweening;

public class CircularMenuController : MonoBehaviour
{
    [Header("菜单配置")]
    [Tooltip("子物体数量，即段数")]
    public int segments = 6;
    [Tooltip("子物体移动的半径")]
    public float radius = 100f;
    [Tooltip("子物体分布的起始角度")]
    public float startAngle = 0f;
    [Tooltip("子物体分布的终止角度")]
    public float endAngle = 359f;

    [Header("动画配置")]
    [Tooltip("动画持续时间")]
    public float duration = 0.5f;
    [Tooltip("打开状态的缓动类型")]
    public Ease openEase = Ease.OutBack;
    [Tooltip("关闭状态的缓动类型")]
    public Ease closeEase = Ease.InBack;

    public bool isOpen = false;
    private Transform[] childTransforms;

    void Start()
    {
        // 获取所有子物体的Transform组件
        childTransforms = new Transform[segments];
        for (int i = 0; i < segments; i++)
        {
            if (i < transform.childCount)
            {
                childTransforms[i] = transform.GetChild(i);
            }
            else
            {
                // 如果子物体数量不足，则创建新的空物体作为占位符
                GameObject placeholder = new GameObject("Placeholder " + i);
                placeholder.transform.SetParent(transform);
                placeholder.transform.localPosition = Vector3.zero;
                childTransforms[i] = placeholder.transform;
            }
        }
    }


    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            ToggleMenu();
        }
    }

    /// <summary>
    /// 切换菜单状态：打开或关闭
    /// </summary>
    public void ToggleMenu()
    {
        if (isOpen)
        {
            CloseMenu();
        }
        else
        {
            OpenMenu();
        }
    }

    /// <summary>
    /// 打开菜单：子物体从中心移动到圆周边缘
    /// </summary>
    public void OpenMenu()
    {
        float angleStep = (endAngle - startAngle) / segments;
        for (int i = 0; i < segments; i++)
        {
            float angle = startAngle + angleStep * i;
            float rad = angle * Mathf.Deg2Rad;
            Vector2 targetPos = new Vector2(Mathf.Cos(rad) * radius, Mathf.Sin(rad) * radius);
            childTransforms[i].DOLocalMove(targetPos, duration).SetEase(openEase);
        }
        isOpen = true;
    }

    /// <summary>
    /// 关闭菜单：子物体从圆周边缘移动回中心
    /// </summary>
    public void CloseMenu()
    {
        for (int i = 0; i < segments; i++)
        {
            childTransforms[i].DOLocalMove(Vector2.zero, duration).SetEase(closeEase);
        }
        isOpen = false;
    }
}

如果代码帮到你，还请点个关注，给个三连。
