Synchronization between client and server - files.

[Arxcis]

What if I get a highscore while I am offline. I want the game to be able to push my new highscore, when internet is back up. I want see global highscore-lists on my client , even if I am offline.

Something that's possible is to save the highscore when you don't have internet, and when you start the game while you have internet, check if it is really a highscore in that level and if it is, push it to the server.

Yes that could work.

Another solution would be to send levelhistory to the server right after player have picked a level. Then you have 2 dictionaries on the server, 1 with client history , 1 with _ server history. Then you run a merge-function on the server which basically makes them identical to each other. And then you send client_history back to client, which stores the new history in its files.

Here is some pseudo - code that could work:

1. Player picks level.
2. Client reads level_history and stores it in a dictionary.
3. Client sends level_history to the server.
4. Server recieves client_level_history, and reads server_level_history into its own dictinary.
5. Server launches the following synchronization-function.

\ For every key in server_history: ** If key is not in client_history: Store server- key + data in client_history.

For every key in client_history: If key is not in server_history Store client key + data in server_history.

     **Else if client_history[key][points] == server_history[key][points]:**
                   Do nothing

      **Else if client_history[key][points]  >  server_history[key][points]:**
                    Store client - key + data   in server_history.

      **Else if client_history[key][points]  <   server_history[key][points]:**
                   Store server-key + data in client_history

1. Server sends the possibly modified client_history back to client.
2. Client recieves and stores the new client_history in its respective file.
3. WINNING!

That could work, and since you have aleardy made pseudocode, maybe we should go for your solution. :-)

Unecessary if we only have storage.py on server.
