First of all, thanks for the help. I’m dabbling in OOP, but I’m nowhere near proficient yet.

I have two classes, house() and town(). In house’s constructor, I want to define an exit from the house to town. I’ve set up a Doors and Exits array in the base class, and in house, I add town to it:

Doors = new Array(new trigger());  
Exits = new Array(new town());

This way, I can check if the player is colliding with the trigger, and if so, I can set level to Exits\* or wherever it is.

My problem is, including Exits = new Array(new town()); in house’s constructor calls town’s constructor, and town has an array Exits, which leads back to house and so on.

So my question is: How would I get around this problem or structure my level class? Is it possible to use “town” to get to new town(); without manually checking if(“town”){ new town(); } etc. Basically, I want to tell flash to create a new town() WHEN I need it, not necessarily during the initial construction, but I don’t want to have to manually call “new town();”

Thanks again for the help!
