OLPCities/Links
A "link" has 2 files. It's neither like 3D objects nor like Hard objects. The avatar can not go behind it. He can only to collide with the "shadow" (figure having the sufix "S") that will transport him to another place that can be another Lot, another City or a "normal" web-page. The Z of a "shadow" is: 0. The Z of a link is 12, like any of the Hard objects
The basic "link" is that to go to a "normal" web-page:
At the "normal" web page you need to put a link to go back to the Lot of OLPCity you came from. The icon to be clicked you see at right.
The "gates" are links to another Lot or City. There are a "gate-in" and a "gate-out". When the avatar arrives to a Lot he arrives going out of a "gate-out". If he likes to go to any other Lot, he collides with the "gateS" (a "shadow") of a "gate-in". A "gate-out" doesn't have "shadow".
