getVariable returns a reference?

[bhaz 0]

Came across something I've never noticed before in a mission I'm designing at the moment:

_groupArray = missionNamespace getVariable( format[ "INT_town_%1_groups", _this select 2 ] );
_groupArray set[ count _groupArray, _spawnedGroup ];

I'm keeping track of groups I spawn in per town so they can be deleted later, and even though I'm adding a new value to the local array, the global is being updated without needing to use setVariable.

Has it always been like this?

Array Operators

Normally arrays are assigned by reference. That means, if you assign array a to array b and change a afterwards, also b is changed. Use the copy operator to avoid this otherwise useful feature.

Never knew that, thanks. :)
