_G

[qaisjp]

What the hell does _G(...) do?

[karlis]

everything that is variable and is not local is stored in _G

[qaisjp]

So

  
testmanny = "hi" 
outputChatBox(_G("testmanny")) 
  

would output "hi" to chatbox?

but

  
local pfft = "hi" 
outputChatBox(_G("pfft")) 
  

wouldn't?

[karlis]

no, they still will show, if the local value exsists at the moment _G is called

EDIT AGAIN:seems that local values rnt stored indeed.

  
number1=1 
string="string" 
local number2=2 
local string2="string" 
for k,v in pairs(_G) do 
   if type(v)~="table" and type(v)~="function" then 
      print(k..":"..v) 
   end 
end
