Hi. I've been programming in LUA for several years now, so I'd thought that I and a few other members of ROBLOX's developer community would answer some questions about programming in LUA.

The following people will be here to answer questions:
Quenty
magnalite
vorlias
Andalf
BlueTaslem


There may be a few other people who jump in here too. So ask away, we're here to answer your LUA questions.

Yes! I would definitely recommend the datastore tutorial on the wiki. A quick rundown though, if you know anything about tables, you can use a datastore in the same way, except you only use a string as a key.

http://wiki.roblox.com/index.php?title=DataStore

You should also check out Crazyman32's datastore editor.

No, I meant it as in a part of a 3D gui.
How would you triangulate the firewall so I can change the color of the matrix gui?

For those saying "Lol its Lua not LUA"

It's actually LUA. It stands for Lightweight Unanimous Arithmetic and is a standard for a system on functional arithmetic with minimal overhead.

I would like to take the time to shamelessly plug qCmdUtl. I just updated it.

I will see if whobloxedwho and asimo3089, owner of EBR and builder extraordinaire respectively, are up to give away some tips.

For this you need to apply the MVC pattern using LUA to establish the Matrix as a separate view in the first place. The Colour property can be found in the C of MVC as it stands for Matrix View Colour and then you can build anything from the 3D Gui using the view by drawing on it with a WACOM tablet. You don't even need LUA really!

This isn't about programming but about game design(?)

So how do you brainstorm game ideas, how do you know when an idea is good/bad?

etc.

Uhh no
Lua is the successor of SOL which means sun in Portuguese. They named it lua because it means moon in Portuguese.

Nope, it's LUA. LUA stands for Lightweight User Actionscript.
