Does anyone know if there's a way to change the default underline links to appear in bold instead; in a way that could be set up once when the game starts?

Add this function into your game:

  <function name="GetCurrentLinkTextFormat" type="string">
    return (GetCurrentTextFormat(GetLinkTextColour()) + "font-weight:bold;")
  </function>

This replaces the built-in GetCurrentLinkTextFormat, to add in an additional "font-weight:bold" CSS style for links.

Jay, where are you finding these functions? I didn't see them in the function list on the docs site.

Thanks again, Jay!

Is there a certain place to put it in the code, it's making the listed exits in bold/underline...but it's not working on game objects I create, which still show up as in default.

george, I do searches through the core source to see how it all works...

Unfortunately, objects don't use the same code. Add this function override as well to your game:

  <function name="ProcessTextCommand_Object" type="string" parameters="section, data">
    <![CDATA[
    objectname = Mid(section, 8)
    text = ""
    colon = Instr(objectname, ":")
    if (colon > 0) {
      text = Mid(objectname, colon + 1)
      objectname = Left(objectname, colon - 1)
    }
    object = GetObject(objectname)
    if (object = null) {
      return ("{" + ProcessTextSection(section, data) + "}")
    }
    else {
      if (LengthOf(text) = 0) {
        text = SafeXML(GetDisplayAlias(object))
      }
      if (game.enablehyperlinks) {
        linkid = ProcessTextCommand_GetNextLinkId()
        colour = ""
        if (HasString(object, "linkcolour") and GetUIOption("UseGameColours") = "true") {
          colour = object.linkcolour
        }
        else {
          colour = GetLinkTextColour()
        }
        style = GetCurrentTextFormat(colour) + "font-weight:bold;"
        return ("<a id=\"" + linkid + "\" style=\"" + style + "\" class=\"cmdlink elementmenu\" data-elementid=\"" + object.name + "\">" + text + "</a>")
      }
      else {
        return (text)
      }
    }
    ]]>
  </function>

(I hate having to replace a large function like this for a single line change, but what can you do?)

Thanks again for this, it's all really aesthetics, but for me personally having objects in bold is easier on the eyes and I think they stand out more from the text and look less like a wiki web-link.

No problem. I'm up for aesthetics myself. The details do make a difference.
