JavaScript implementation of a simple multiplayer billiards-like game

"Chapayev game" (Russian: "игра в Чапаева") is a game played on a checkerboard, a hybrid of checkers and billiards.

Game rules and funny details are present on Wikipedia

The project has been started as a programming exercise while studying Javascript and various JS libraries. In the same time I just wanted to play Chapayev with friends, so I decided to implement multiplayer version as well.

JS libraries used so far:

• Raphaёl -- for game graphics and animation
• Socket.io -- for client/server interaction suitable for any browser
• Node.js -- for server side
• Knockout.js -- for structuring the code, introducing data model in UI using MVVM pattern
• jQuery -- for querying the DOM, providing templates for Knockout.
• Sylvester -- for vector/matrix operation needed for collision resolving.

chapayev-js's Issues

Funny messages, captions, etc.

To add some fun, use them instead of boring "you won", "you lose" and similar.

Create a bot to play with while there are no online players

The bot should play more or less randomly (+- 5/10 degrees from the optimal angle) to be interesting and non-invincible :)

There might be also different strategies for choosing target pieces.

The bot should be implemented on the client side to be able to play offline.

Make players pairing process more friendly

• add /replay command, it should send the invitation to the most recently played opponent
• the server should start the game if two players are inviting each other

Make autofocus on console input.

Focus should shift to console after every mouse click. This should make chatting more convenient.

Implement the rest of client/server protocol

Messages which are not implemented yet:

• decline
• gameresult

Implement automatic client reconnect

Currently, the client is not trying to reconnect after the server has been restarted.

Try Faye instead of Socket.IO

Its site is here:

Synchronize nicknames between client and server

Currently, initial nickname which is loaded in KO model from the cookie is not synced with server on application startup.

Horizontal scroll in console in Firefox

Subj

Chat with bots

Pieces might disappear from the board

Sometimes, the piece dissolves after collision even if it's not out of the board.

Sending messages through socket doesn't work in Opera.

Used Opera 11.0. Tried to update to the last version of client and server socket.io (client = 0.6.2, server = 0.6.12), doesn't seem to help :(

Pieces advance

Implement pieces advance, level by level (after each win) in correspondence with typical Chapayev rules (see on Wikipedia).

Fix bug with a piece in (0, 0) corner after collision resolving

Sometimes a piece might end up in (0, 0) after a collision resolving.

This typically happen after a huge number of small collisions, resulting in NaN values.
Also, mysterious "collision with undefined" happened once, leading to the same bug.

Make console commands history

It should be possible to recall last command with 'up' arrow.
'Up' and 'down' arrows should work as in shell command line.

Daemonize server.js on eth0

Use 'god' tool, it looks promising:

Make opponent's pieces always on the top

It's not convenient to push pieces down, so it makes sense to display your own pieces on the bottom and opponent's ones -- on the top.

The page stays in "Waiting for..." state

After connecting to the server, the status bar shows "Waiting for eth0.net.ua..." all the time and site's favicon is in "loading" state as well, despite the fact we have successfully connected.

Note: reproduces in Chrome only. Firefox works fine.

Add URLs to specific games

Make links with shebangs (smth. like iveselov.info/chapayev/#!23131123).

This will make it possible to send a link to the specific game.
