图文混排更新到超链接这儿&＃xff0c;好像也差不多了&＃xff0c;不过就在最后一点&＃xff0c;博主也表现得相当不专业&＃xff0c;直接整合了山中双木林同学提供的超链接的解决方案&＃xff0c;博主甚至没来得及细看就直接复制了&＃xff0c;但感觉还是挺好用的。
博主已经将超链接的功能直接整合到了之前的InlineText和InlineSpriteText的两个脚本中
1.定义超链接的正则表达式和事件监听
#region 超链接/// /// 超链接信息列表/// private readonly List m_HrefInfos &＃61; new List();/// /// 文本构造器/// private static readonly StringBuilder s_TextBuilder &＃61; new StringBuilder();/// /// 超链接正则/// private static readonly Regex s_HrefRegex &＃61;new Regex(&＃64;"\n\s]&＃43;)>(.*?)()", RegexOptions.Singleline);[System.Serializable]public class HrefClickEvent : UnityEvent { }[SerializeField]private HrefClickEvent m_OnHrefClick &＃61; new HrefClickEvent();/// /// 超链接点击事件/// public HrefClickEvent onHrefClick{get { return m_OnHrefClick; }set { m_OnHrefClick &＃61; value; }}/// /// 获取超链接解析后的最后输出文本/// /// protected string GetOutputText(){s_TextBuilder.Length &＃61; 0;m_HrefInfos.Clear();var indexText &＃61; 0;foreach (Match match in s_HrefRegex.Matches(text)){s_TextBuilder.Append(text.Substring(indexText, match.Index - indexText));s_TextBuilder.Append(""); // 超链接颜色var group &＃61; match.Groups[1];var hrefInfo &＃61; new HrefInfo{startIndex &＃61; s_TextBuilder.Length * 4, // 超链接里的文本起始顶点索引endIndex &＃61; (s_TextBuilder.Length &＃43; match.Groups[2].Length - 1) * 4 &＃43; 3,name &＃61; group.Value};m_HrefInfos.Add(hrefInfo);s_TextBuilder.Append(match.Groups[2].Value);s_TextBuilder.Append("");indexText &＃61; match.Index &＃43; match.Length;}s_TextBuilder.Append(text.Substring(indexText, text.Length - indexText));return s_TextBuilder.ToString();}/// /// 点击事件检测是否点击到超链接文本/// /// public void OnPointerClick(PointerEventData eventData){Vector2 lp;RectTransformUtility.ScreenPointToLocalPointInRectangle(rectTransform, eventData.position, eventData.pressEventCamera, out lp);foreach (var hrefInfo in m_HrefInfos){var boxes &＃61; hrefInfo.boxes;for (var i &＃61; 0; i /// 超链接信息类/// private class HrefInfo{public int startIndex;public int endIndex;public string name;public readonly List boxes &＃61; new List();}#endregion2.在文本绘制完成后处理超链接的包围盒
#region 处理超链接的包围盒// 处理超链接包围框UIVertex vert &＃61; new UIVertex();foreach (var hrefInfo in m_HrefInfos){hrefInfo.boxes.Clear();if (hrefInfo.startIndex >&＃61; toFill.currentVertCount){continue;}// 将超链接里面的文本顶点索引坐标加入到包围框toFill.PopulateUIVertex(ref vert, hrefInfo.startIndex);var pos &＃61; vert.position;var bounds &＃61; new Bounds(pos, Vector3.zero);for (int i &＃61; hrefInfo.startIndex, m &＃61; hrefInfo.endIndex; i &＃61; toFill.currentVertCount){break;}toFill.PopulateUIVertex(ref vert, i);pos &＃61; vert.position;if (pos.x 3.看一下文中中超链接的输入规则
4.简单写了一个测试脚本&＃xff0c;用来监听点击事件
using UnityEngine;
using System.Collections;public class TestClickInlineText : MonoBehaviour {private InlieText _text;void Awake(){_text &＃61; GetComponent();}void OnEnable(){_text.onHrefClick.AddListener(OnHrefClick);}void OnDisable(){_text.onHrefClick.RemoveListener(OnHrefClick);}private void OnHrefClick(string hrefName){Debug.Log("点击了 " &＃43; hrefName);// Application.OpenURL("www.baidu.com");}
}
5.运行截图&＃xff1a;
6.更新速度实在太慢&＃xff0c;为了早点完结图文混排&＃xff0c;这里的功能是复制的&＃xff0c;有什么疑问的话&＃xff0c;可以再讨论&＃xff0c;这里的功能也就更新得差不多了&＃xff0c;最后再给一个最新的源码链接&＃xff0c;短时间没有特殊的功能或者bug&＃xff0c;就不打算再更新了
