A hide for Draw?

[GameWalrus]

I was wondering, considering I've seen things that look like they've been done using Draw, is there a way to hide things done using draw? If so, how?

[lua]
draw = setmetatable({},{__index = function() return (function() return 0 end) end})
[/lua]
:v:

draw = setmetatable({},{__index = function() return (function() return 0 end) end})

Could you explain to me how that works? Sorry, I'm still rather new to Lua.

Nevermind, apparently Draw will take a boolean whether or not to draw itself. Silly me.

Whenever you try to access a non existing member of the draw table (which is equal to the first argument of setmetatable) the __index function of the metatable (which is the second argument to setmetatable) will be called, which in turns returns an empty function (which returns 0 to prevent scripts using draw.GetFontSize from erroring)

All in all it's a shortcut to setting all draw.* functions to do nothing.
