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

[Steve]

If you don't want to activate it when doing stuff and just want to see it instantly (probably for testing purposes I guess) use this;

void OnStart()
{
SetMessage("Messages", "NameofMessage", 0);
}

For the .lang part see james' post.
And Steve, as far as I'm concerned the O and S in OnStart need to be capitalized.

I saw I forgot the capilization, I changed it immediately
It should work now.
