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. | The comment is valid but misleading, so I moved it here.

Revision as of 11:52, 11 January 2023
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.
player getVariable ["yolo",call {hint "!"; true}];The hint will always print, even if the "yolo" variable exists.
