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("www.baidu.com");
}
}
5.运行截图:
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
