基于UGUI的Unity画线工具

最近项目里需要做一个画线的小游戏，LineRenderer不是很好用，自己撸了一个小工具，效果如下

下面上代码

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using FMCShape;

    public class MyLineDrawer : Image
    {
   
   
        public List<Vector2> pointer = new List<Vector2>();
        public float radio = 30;
        private int headPointCount = 7;//头部顶点数量
        private Vector2 offset;
        protected override void Awake()
        {
   
   
            base.Awake();
            offset = new Vector2(Screen.width * 0.5f, Screen.height * 0.5f);
        }
        protected override void OnPopulateMesh(VertexHelper toFill)
        {
   
   
            toFill.Clear();
            if (pointer.Count >= 2)
            {
   
   
                for (int i = 1; i < pointer.Count; i++)
                {
   
   
                    Draw(toFill, pointer[i - 1], pointer[i]);
