java - Online games: update the clients with deltas or with the new status -


i'm implementing online chess android , have question how update players other player's movements.

for example lets imagine player1 moves tower a1 a7.

what should do?

  • send player2: "a1 a7" (with kind of checksum of full board avoid errors)
  • send player2 full board 32 pieces

support both.

  • only send deltas during events, but
  • allow client request full state, reason, through separate api.
  • include , increment sequence number each event trivial client detect missed updates.
