How can I find warden-like code on a non-WoW or non-blizz game?

--This is a post about a game that is not WoW! xD I am trying to find a Warden-like object in this game and/or how to inject lua scripts into this game. This is the place I thought of since WoW is much more advanced than Roblox.--
I said warden-like!
I like to play Roblox and I like to try to edit scripts while playing.
These scripts are in lua, but when I edit a single byte of their code I get kicked from the game(unless I'm offline).

I get the feeling that Roblox uses something like Warden for their scripts, which I want to see if I can identify and kill, OR I want to find a way to inject a lua script into the game.

This is how it happens:
1. Enter game
2. Select my sword
3. Edit sword code
4. Not even halfway through step three I get kicked >.>

What would you recommend I do first to find the Warden-like code or something like that?
Or how would I inject/run lua scripts in the game.

I don't need a game specific thing I just need to know how or if either thing is done or can be done in WoW.
