AN XP SCRIPTING QUESTION (HELP ME IMPROVE MY GAME)

A friend of mine on the forum has pointed out that I should hide the game's hud during certain story events to improve immersion. I've been trying to figure out how to do so but just haven't been able.

The script I'm using is part of the:
Tons of Add-ons by Blizzard
Version: 5.40b

Specifically I'm using:
Blizz-Art lagless HUD by Blizzard
Version: 1.3b

Here's a link to the script (technically its a newer version but that's all I could find to link to I'm sure it's still basically the same)

So, basically I want to be able to turn the hud off and on in game. Your help would be very appreciated. If you can solve this for me I'll put your username in the game credits if you'd like.

I know that there is a script button within the event commands menu but my attempts to use that haven't worked. I just don't know enough about scripting to do this on my own.

It works! :D

Thanks LockeZ.

Since you solved that for me I'd be willing to put your name in the credits.
So, would you like your username added to the credits for my game's next update?
Either way is fine by me.

Again thank you so much for your help I didn't think I'd get a solution so quickly.
