Checklist¶

Check these before you hand in your client.

• WebSocket: send each line as its own message, without a newline. Each message you receive is one line.
• Telnet: end each line you send with a newline. Split what you receive on newlines.
• Right after you connect, say hello with your protocol version. The server waits for it.
• Log in only after the hello OK.
• Save your session token for reconnecting.
• Give every request its own id (counting up works).
• Remember which ids are still waiting for an answer.
• Don't expect the next line to be your answer. Events can come first.
• Use the match ID to know which match an event is for.
• Check the error code, not the error text.
• Got FATAL? Connect again from the start.
• Write commands in lowercase.
• Send data as one JSON object, made with a JSON library: {"player": "jane doe"}.
• WebSocket: keep reading messages, so your library answers the server's pings.
• Telnet: answer PING with PONG.
• Lost connection? Reconnect fast, with your session token.
• Got a time_limit in game.your_turn? Move before it runs out.
• Read reason in game.result to know why a match ended.
• One login per name. A name that is already logged in gives AUTH_FAILED.
• Only read the data fields you need. Others may change.
