图文混排更新到超链接这儿,好像也差不多了,不过就在最后一点,博主也表现得相当不专业,直接整合了山中双木林同学提供的超链接的解决方案,博主甚至没来得及细看就直接复制了,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/// <summary>/// 超链接信息列表/// </summary>private readonly List<HrefInfo> m_HrefInfos = new List<HrefInfo>();/// <summary>/// 文本构造器/// </summary>private static readonly StringBuilder s_TextBuilder = new StringBuilder();/// <summary>/// 超链接正则/// </summary>private static readonly Regex s_HrefRegex =new Regex(@"<a href=([^>\n\s]+)>(.*?)(</a>)", RegexOptions.Singleline);[System.Serializable]public class HrefClickEvent : UnityEvent<string> { }[SerializeField]private HrefClickEvent m_OnHrefClick = new HrefClickEvent();/// <summary>/// 超链接点击事件/// </summary>public HrefClickEvent onHrefClick{get { return m_OnHrefClick; }set { m_OnHrefClick = value; }}/// <summary>/// 获取超链接解析后的最后输出文本/// </summary>/// <returns></returns>protected string GetOutputText(){s_TextBuilder.Length = 0;m_HrefInfos.Clear();var indexText = 0;foreach (Match match in s_HrefRegex.Matches(text)){s_TextBuilder.Append(text.Substring(indexText, match.Index - indexText));s_TextBuilder.Append("<color=blue>"); // 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,name = group.Value};m_HrefInfos.Add(hrefInfo);s_TextBuilder.Append(match.Groups[2].Value);s_TextBuilder.Append("</color>");indexText = match.Index + match.Length;}s_TextBuilder.Append(text.Substring(indexText, text.Length - indexText));return s_TextBuilder.ToString();}/// <summary>/// 点击事件检测是否点击到超链接文本/// </summary>/// <param name="eventData"></param>public void OnPointerClick(PointerEventData eventData){Vector2 lp;RectTransformUtility.ScreenPointToLocalPointInRectangle(rectTransform, eventData.position, eventData.pressEventCamera, out lp);foreach (var hrefInfo in m_HrefInfos){var boxes = hrefInfo.boxes;for (var i = 0; i < boxes.Count; ++i){if (boxes[i].Contains(lp)){m_OnHrefClick.Invoke(hrefInfo.name);return;}}}}/// <summary>/// 超链接信息类/// </summary>private class HrefInfo{public int startIndex;public int endIndex;public string name;public readonly List<Rect> boxes = new List<Rect>();}#endregion
2.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 = new UIVertex();foreach (var hrefInfo in m_HrefInfos){hrefInfo.boxes.Clear();if (hrefInfo.startIndex >= 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 = vert.position;var bounds = new Bounds(pos, Vector3.zero);for (int i = hrefInfo.startIndex, m = hrefInfo.endIndex; i < m; i++){if (i >= toFill.currentVertCount){break;}toFill.PopulateUIVertex(ref vert, i);pos = vert.position;if (pos.x < bounds.min.x) // 换行重新添加包围框{hrefInfo.boxes.Add(new Rect(bounds.min, bounds.size));bounds = new Bounds(pos, Vector3.zero);}else{bounds.Encapsulate(pos); // 扩展包围框}}hrefInfo.boxes.Add(new Rect(bounds.min, bounds.size));}#endregion
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,用来监听点击事件
using UnityEngine;using System.Collections;public class TestClickInlineText : MonoBehaviour {private InlieText _text;void Awake(){_text = GetComponent<InlieText>();}void OnEnable(){_text.onHrefClick.AddListener(OnHrefClick);}void OnDisable(){_text.onHrefClick.RemoveListener(OnHrefClick);}private void OnHrefClick(string hrefName){Debug.Log("点击了 " + hrefName);// Application.OpenURL("");}}

6.更新速度实在太慢,为了早点完结图文混排,这里的功能是复制的,有什么疑问的话,可以再讨论,这里的功能也就更新得差不多了,最后再给一个最新的源码链接,短时间没有特殊的功能或者bug,就不打算再更新了
