Use of 'this' demo

The Portal class contain the most useful demonstration of using the 'this' keyword. Look closely as to how the constructor and the 'setPortal' method within that class work together.

It also demonstrate another way to create linked portals within the same and within different worlds.

Wow! I don't find where is the switch to another portal is made? Why getActor() works on a new port?

@Olexandra, the "getActor" method may probably be better named as "takeActor" as that is what its partner portal is asking it to do. The link is made when the second constructor (the one with its partner portal passed to it) is used.

Thanks for the answer. It seems I've done the same, but only one port is working. The other keeps the actor and doesn't let it move. It depends on which Port I create first. Maybe you know what might be the problem? https://www.greenfoot.org/scenarios/27113 There is an exception on the site, but it works on my machine. I guess that's because of the images I upload to the program.
