A place for people to meet and play connect-4 with each other
Install leiningen - http://leiningen.org/
Go to the base folder, and type lein run - it will use port
8001 for websocket connections and port 4222 for the nrepl connection
Go to clients/ and run ./client.py --name Alice
There are two reference players that you can play against, and also two game engines that you can use, like this:
./client.py --name Bob --engine random --against random
./client.py --name Carl --engine neuralq --against aima
The AIMA reference client is from here. It's an IterativeDeepeningAlphaBetaSearch that's been restricted to 0.5 seconds of computation time.
You will need websocket-client, which can be installed by pip install websocket-client
Clients connect via websocket.
From client1:
{:type "start", :id "Alice"}
From client2:
{:type "start", :id "Bob"}
To client1:
{
:type "state",
:turn 1 :you 1
:state [0,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0]
}
From client1:
{:type "move", :move 0}
State representation is column-major
To client2:
{
:type "state",
:turn 2 :you 2
:state [1,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0]
}
The move you make is a column number
From client2:
{:type "move", :move 2}
To client1:
{
:type "state",
:turn 1 :you 1
:state [1,0,0,0,0,0,
0,0,0,0,0,0,
2,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0]
}
And so on. When a winner appears, the server sends a state update:
To client1:
{
:type "state",
:winner 1
:turn 0 :you 1
:state [1,0,0,0,0,0,
2,1,0,0,0,0,
2,2,1,0,0,0,
2,1,2,1,0,0,
1,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0]
}
To client2:
{
:type "state",
:winner 1
:turn 0 :you 2
:state [1,0,0,0,0,0,
2,1,0,0,0,0,
2,2,1,0,0,0,
2,1,2,1,0,0,
1,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0]
}
and then sends
{:type "end"}
- If the other player terminates their connection, server will send
{:type "disconnected"}
- Any invalid messages result in a reply
{:type "ignored", :msg <copy of msg>}
- You can request the current state like this:
From client1:
{
:type "state_request"
}
To client1:
{
:type "state"
:turn 1
:you 1
:state [1,0,0,0,0,0,
0,0,0,0,0,0,
2,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0,
0,0,0,0,0,0]
}
