Additionally, Amber provides a set of classes which enable the development of multi-user and distributed virtual reality systems using multiple PCs and serial connections. The following sections briefly describe some of the concepts for game worlds under development. In this world, the players encounter a series of floating three dimensional objects. The players are able to interact with the floating objects by touching them. Most of these objects give the players points, small prizes, or other rewards.
Players also have the ability to pick up and drop objects which they find.
Two of the objects reveal keys when touched by the players. These keys can be used to unlock the gate leading to the next level by inserting them into the keyholes next to the gate. However, the gate will only open if both keys are placed into the keyholes at the same time. Since the keyholes are spatially separated, this can only happen if both players possess one key and coordinate with each other to unlock the gates at about the same time. In the paintball world, the players find themselves in orbit around a strange planet which is itself orbited by a series of polyhedra.
