[SCRIPT] How to appear a text message on screen?

[Steve]

This should work you only have to fill in the area's
void OnStart()
{
SetEntityPlayerInteractCallback("NAME_OF_OBJECT", "MSG", false);
}
void MSG(string &in entity)
{
SetMessage("Messages", "msgname", 0);
}
And in the .LANG file

<CATEGORY Name="Messages">
<Entry Name="msgname">Put Text Here.</Entry>
</CATEGORY>
