Setting Variables True/False in Tables?
ModeString = {"Normal", "Colored"}
ModeValue = {_G.normal, _G.colored}
function PickMode()
local nextmode = math.random(#ModeString)
Talk("The gamemode is ".. ModeString[nextmode],2, "")
ModeValue[nextmode] = true
end
function ResetMode()
for i,v in pairs(ModeValue) do
v = false
end
end
This is a portion of a functioning script. These functions, however, aren't working entirely.
The non-functioning portion is where I try to set a global variable as true
ModeValue[nextmode] = true
The code works perfectly up until this line. It seems to skip this line without displaying an error in the output.
Also, ResetMode()obviously doesn't work; I used the same thought process as the line above.
Is there an error in this code, or is this simply not possible?

Changing v changes v. v is not linked up to the corresponding thing in the table, or where it came from.
The same is said for how you use _G.normal. The list doesn't remember where the expression came from. It'll simply drop a false or true in there. Modifying ModeValue[nextmode] modifies ModeValue. You didn't tell it to change _G so it won't.
For ResetMode:
In order to modify ModeValue, you have to explicitly reference it:
ModeValue[i] = false
For PickMode:
The simplest way is to store the name:
ModeValue = {"normal", "colored"}
----
_G[ModeValue[nextmode]] = true
however at that point you might as well just use ModeString instead.
Is there a particular reason you're using booleans in _G instead of something more controlled, e.g., a list of modules to run, for example?
