Technical Implementation

Just some comments to myself:

• Server controls what is on the map (the client shall not assume anything)

Internal actions

• Show Map
• Show Map at pos x,y
• Show Map at nest n
• Help about n (predefined constants in app) - or use the wiki pages?
• Show spieces chat with prepared message/location x,y

etc

Determine water vs land

Client <-> Server

• All actions are asynchronous
• Send all waiting actions (in client) to one server script using a background thread.
  • The client application holds a list of actions waiting to be performed (with a generated serial id)
  • A json-list with actions
  • All actions have a serial number (unique to user and say 5 min?) and info on what to perform
  • If the action already took place (serial number) just send the updated info (for that action)
  • The server responds with apropriate data on all actions or error messages and also a part with new data (that might have been changed)
  • The client updates data and remove confirmed actions from the list of waiting actions
  • The client sends a new request with waiting actions (including those who where not confirmed)

• Notification from server if nearby actions take place, the notifications shall contain enough data to update the info in the client (typically attacks)
