Unity TMP超链接和图文混排

游戏内聊天内容离不开的就是超链接 比如点击物品名字 显示该物品的详细信息等等

public class Link : MonoBehaviour
{
    
    
    public TextMeshProUGUI proUGUI;
    private Action<string, string> linkClickCallBack;

    private void Start()
    {
    
    
        string text = "<u><link=100101>Test</link></u>\n<color=#ff0000>red</color>\n<link=100102>Test1</link>";
        Action<string, string> action = (linkId, linkText) => 
        {
    
    
            Debug.LogErrorFormat("link click callback, linkId: {0}, linkText: {1}", linkId, linkText);
        };

        SetMsg(text, action);
    }

    private void SetMsg(string text, Action<string, string> action)
    {
    
    
        linkClickCallBack = action;
        proUGUI.text = text;
    }

    private void Update()
    {
    
    
        if (Input.GetMouseButtonDown(0))
        {
    
    
            int linkIndex = TMP_TextUtilities.FindIntersectingLink(proUGUI, Input.mousePosition, null);
            if (linkIndex != -1)
            {
    
    
                TMP_LinkInfo linkInfo = proUGUI.textInfo.linkInfo[linkIndex];
                linkClickCallBack?.Invoke(linkInfo.GetLinkID(), linkInfo.GetLinkText());
            }
        }
    }
}

点击超链接触发的回调

图文混排

TP将碎图打包成图集导出到工程中

然后调用接口

string text = "test sprite \n<sprite=0>\n<sprite=1>\n<sprite=2>";
Action<string, string> action = (linkId, linkText) => 
{
    
    
    Debug.LogErrorFormat("link click callback, linkId: {0}, linkText: {1}", linkId, linkText);
};

SetMsg(text, action)

运行结果

调整单个图片的偏移量

使用tmp制作超链和图文混排简直不要太简单
