unity 衣服比对

根据提供的引用内容，unity 衣服比对是通过获取精灵(sprite)的点位信息，并与PolygonCollider2D的点位信息进行匹配，然后调整大小来实现的。具体方法是通过遍历PolygonCollider2D的Point点位，将其放大到与精灵的点位匹配。可以使用以下脚本实现该功能：

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

public class Test : MonoBehaviour {

    PolygonCollider2D poly2D;
    Vector2[] pos_save; // 存放PolygonCollider2D的Point点位
    public float scale = 100f;

    void Start() {
        poly2D = GetComponent<PolygonCollider2D>();
        SetPos();
    }

    void SetPos() {
        pos_save = poly2D.GetPath(0);
        for (int i = 0; i < pos_save.Length; i++) {
            pos_save[i *= scale;
        }
        poly2D.SetPath(0, pos_save);
    }
}

将以上代码拖放到Unity中的一个物体上即可实现衣服比对的效果。这个脚本会获取PolygonCollider2D的点位信息，并将其放大到与指定精灵的点位匹配。您可以根据实际需求调整scale的值来控制放大的比例。该脚本适用于Unity的任何版本，只需将其放入Assets文件夹即可，无需额外操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
