Singleton Pattern

[alexgeek]

Hi,
I have a movieclip called "GameArea" on my stage (instance name "gameArea") and have generated a class for it.
How can I incorporate the singleton pattern so that when I reference the GameArea class in other files, it gives me an instance that is on the stage?

Thanks, Alex.

alexgeek,

Another option would be to use a Locator / Multiton Pattern to retrieve your GameArea instance. This involves creating a GameAreaLocator class which comprises only of static members and properties:



public class GameAreaLocator
{
private static var INSTANCE : GameAreaLocator;

public static function setInstance(instance : GameArea) : void
{
INSTANCE = instance;
}

public static function getInstnace() : GameArea
{
if (INSTANCE is GameArea)
{
return INSTANCE;
}
else
{
throw new IllegalOperationError("GameArea instance must be set via GameAreaLocator.setInstance() before retrieval!");
return null;
}
}
}
