identify robots as simulated or representations of physical robots

[vital-dhaveloose]

How else can we scan for physical robots only in the physical world and for virtual robots only in the virtual world. Differently put: If no distinction can be made between these two types of robots, why would we scan in the real world? We can just scan the virtual world and get all the information we need there.

[MattiasBuelens]

Proposed solution:

• Indicate the type of robot when creating the PlayerClient.
• Rename SpectatorHandler.playerRolled to playerSetup.
• When player numbers are rolled, send all of your own data (player ID, number, type, width, height,...) along with the rolled broadcast. (related to #17) Probably good to make a simple Player class out of this.
• Spectators call playerSetup on their handlers when receiving a rolled.
• Player send the same data along with every update as well for spectators to receive.

This should allow simulators to properly initialize players before the game is started, while still allowing non-simulating spectators to join at any time without missing out on critical information.
