The easiest way to do that is to use the "not" operator.</description> <code> local bool = false if bool then print("Boolean is false, this code is not run!") end // Boolean is now being inverted ( false -> true ) bool = not bool if bool then print("Boolean has been inverted and is now true!") end // This also works backwards. Note how "!" can be used in place of "not" bool = !bool if bool then print("Boolean is false again, and won't be printed!") end </code> <output>Boolean has been inverted and is now true!</output> </example>
