AIGS 2009 Update

Updated with almost everything necessary to play the tournament.  I still need to implement the game timer per side.  I will have the up before AI class meets Monday.

All of the changes that are mentioned in the Tournament Rules document have been completed with the following notes:

  • Always 3 players per team
  • Not guaranteed to be solvable (though I haven’t seen an unsolvable one yet).
  • You can only capture flags on the other side of the board
  • Flags respawn at random locations on your side of the map
  • You can only see your flags when they have not been captured
  • Non-wall squares you cannot see will be sent as a ‘*’
  • Captured players will spawn adjacent to their home base
  • If no location is available, they will try further out in concentric circles

Behavior of respawning flags:

  • If the original location is occupied by a player that can pick up the flag, they will immediately.
  • If the original location is occupied by a player that can not pick up the flag (wrong team or already holding a flag), the flag will spawn in a nearby available square.
  • This may change in class today, if so the server will be updated to match the requirements in class.

Also, the timer has been implemented.  Once you have used your 3 minutes, the server will not ask you to take another turn

Finally, changes from today’s class:

  • Enable random seeds for tournaments (0 to use time)
  • Add flag spawn points
  • Players can move onto enemy spawns
  • Players cannot move onto their own spawns
  • Flag carrying players cannot move onto spawns.
  • Bases and flag spawns have vision of eight adjacent
  • Players have Manhattan vision of 4 (as opposed to old vision algorithm)
  • Display fog of war with non-constant players
  • Add board state to YourTurn
  • Add remaining time messages

New packets of interest:

CreateTournament

  • Creates a new tournament map with the given seed.
  • Use 0 to use the server’s system time as a seed.

SetConstantPlayer

  • For the server to always treat you as player 0.
  • Will flip the board so that you are on the left.

RequestScores

  • Should return each teams current score.
  • Your teams score should be first followed by your opponents
