Is there a more elegant way to set this boolean value? SetScript() is a game API, while "OnClick" is its handler. What is important is the method that triggers when I click on the checkbutton.

local foo = true

checkbutton:SetScript("OnClick", function()
   if foo == true then foo = false
   else foo = true
   end
end)

a more elegant way ?

Simply assign the negation, unconditionally: not foo

This works in Lua, and in essentially every other language.

checkbutton:SetScript("OnClick", function()
   foo = not foo
end)

If we're flipping {0, 1} integers instead of booleans, then the relevant idiom is to assign 1 - foo.
