View source for Talk:getVariable

Only way I found to see if variable had even been assigned:
  if (format ["%1", _obj getVariable "myVar"] == "<NULL>") then {
   // initialize it
  };

This also works:

   _check = _obj getVariable "myVar";
   if (isNil "_check") then
   {
      // initialize it
   };

'''defaultValue''' is processed even if the default isn't used.

The [[hint]] will '''always''' print, even if the "yolo" variable exists.

The comment is valid but misleading, so I moved it here. It is not true that the default value will be processed even if the variable is defined. It will be processed before when code is compiling, in order to obtain default value. It is simple array, and like with every array, if you put expression into it it will be executed in order to obtain the value.
