Unity 图文混排超链接图片均可点击
1.在其他博主的基础上，增加了图片可以点击的功能，因为我临时遇到了这个需求，这应该是图文混排的终极版本了吧，如果以后图文混排相关功能还有增加的话，我再临时更新此篇文章吧！希望可以帮到拥有同样需求的你们，谢谢！
2.此代码为图文混排代码
using System;
using System.Collections.Generic;

using UnityEngine.EventSystems;
using UnityEngine.UI;
/// m_ImagesPool = new List();

/// m_ImageInfos = new List();
/// ", RegexOptions.Singleline);
private static readonly Regex s_ImageRegex1 =
new Regex(@"" , RegexOptions.Singleline);
/// (m_ImagesPool);
}
if (m_ImagesVertexIndex.Count > m_ImagesPool.Count)
{
var resources = new DefaultControls.Resources();
var go = DefaultControls.CreateImage(resources);
go.layer = gameObject.layer;
var rt = go.transform as RectTransform;
if (rt)
{
rt.SetParent(rectTransform);
rt.localPosition = Vector3.zero;
rt.localRotation = Quaternion.identity;
rt.localScale = Vector3.one;
}
m_ImagesPool.Add(go.GetComponent());
}
var spriteName = match.Groups[1].Value;
var size = float.Parse(match.Groups[2].Value);
var id = match.Groups[5].Value;
var img = m_ImagesPool[m_ImagesVertexIndex.Count - 1];
if (img.sprite == null || img.sprite.name != spriteName)
{
//UI.UpdateSpriteImage(img, "", "");

};

}
for (var i = m_ImagesVertexIndex.Count; i < m_ImagesPool.Count; i++)
{
if (m_ImagesPool[i])
{
m_ImagesPool[i].enabled = false;
}
}
}
protected override void OnPopulateMesh(VertexHelper toFill)
{
var orignText = m_Text;
m_Text = m_OutputText;
base.OnPopulateMesh(toFill);

var pos = vert.position;
for (int j = endIndex, m = endIndex - 3; j > m; j--)
{
toFill.PopulateUIVertex(ref vert, endIndex);
vert.position = pos;
toFill.SetUIVertex(vert, j);
}
}
}
if (m_ImagesVertexIndex.Count != 0)
{
m_ImagesVertexIndex.Clear();
}
//处理图片包围狂
foreach (var imageInfo in m_ImageInfos)
{

toFill.PopulateUIVertex(ref vert, hrefInfo.startIndex);

var bounds = new Bounds(pos, Vector3.zero);

{

bounds = new Bounds(pos, Vector3.zero);
}
else
{
bounds.Encapsulate(pos); // 扩展包围框
}
}
hrefInfo.boxes.Add(new Rect(bounds.min, bounds.size));
}
}
/// " ); // 超链接颜色
var group = match.Groups[1];
var hrefInfo = new HrefInfo
{
startIndex = s_TextBuilder.Length * 4, // 超链接里的文本起始顶点索引
endIndex = (s_TextBuilder.Length + match.Groups[2].Length - 1) * 4 + 3,

};

s_TextBuilder.Append(outputText.Substring(indexText, outputText.Length - indexText));
return s_TextBuilder.ToString();
}
/// boxes = new List();
}
/// ImageBoxes = new List();
}
}
3.此代码为添加点击事件代码
using UnityEngine;
public class testHref : MonoBehaviour
{
public LinkImageText textPic;
void Awake()
{
textPic = GetComponent();
}
void OnEnable()
{
textPic.onHrefClick.AddListener(OnHrefClick);
textPic.onImageClick.AddListener(OnHrefClick1);
}
void OnDisable()
{
textPic.onHrefClick.RemoveListener(OnHrefClick);
}
private void OnHrefClick(string hrefName)
{
Debug.Log("点击了 " + hrefName);
}
private void OnHrefClick1(string hrefName)
{
Debug.Log("点击了 " + hrefName);
}
