Hi

I’m just wondering if creating (unnessesary) objectreferences take alot of memory or affects performance?

ie:  
if I have a _graphicManager_ class and a _dataManager_ class  
Lets say I have a function in _graphicManager_ that creates a movieClip, and calls it from the _dataManager_:

[COLOR=“RoyalBlue”]myGraphicManager.createMC();[/COLOR]

Sometimes I like to call it like this:

[COLOR=“RoyalBlue”]someVar = myGraphicManager.createMC();[/COLOR]

to keep a refrence in my _dataManger_ for more readable code and easy access. I’ll then have a reference in the _graphicManager_ and the _dataManager_. Is this bad? Cause I can always just keep it in the _graphicManager_ and refrence it with

[COLOR=“RoyalBlue”]myGraphicsManager.someVarMC;[/COLOR]  
(instead of useing “someVar”)

Any views on this?
