Status

Chunky Monkey is no longer being maintained by Huin. It does not run anything that could be considered a full game experience.

Worlds generated by Alpha or Beta Notchian clients or servers can be loaded by the server.

Features include:

• Compatibility with Minecraft Beta clients.
• Blocks may be dug, items picked up, and blocks placed.
• Crafting using the 2x2 or 3x3 crafting grids and the furnace.
• Partial item physics.
• World persistency.
• Basic world generation.

Currently missing features include:

• Block physics.
• Complete item physics (there is a minimal implementation in place).
• Mob behaviour.
• Many block interactions.
• Decent world generation.

Contributing

Huin is no longer actively developing Chunky Monkey. People are welcome to take it over with a fork.

Requirements

The Go toolchain must be installed. Note that chunkymonkey is developed against the current stable release of the Go toolchain, so might not compile against the weekly releases (gofix might be able to fix such cases).

Building & Testing

Any of the binaries in the cmd subdirectory can be built with the standard go command, for example, the server can be compiles with:

$ go install github.com/huin/chunkymonkey/cmd/chunkymonkey

The mocks can be regenerated with:

$ make clean mocks

The unit tests require GoMock to be installed:

$ go install code.google.com/p/gomock/mockgen

The unit tests can be run with:

$ go test github.com/huin/chunkymonkey/...

Running

Serve up a single player world:

$ chunkymonkey ~/.minecraft/saves/World1
2010/10/03 16:32:13 Listening on  :25565

Record/replay

For debugging it is often useful to record a player's actions and replay them one or more times later. This makes it possible to simulate multiplayer games without having real people logging in.

To record a session, run the intercept proxy:

$ intercept -record player.log localhost:25567 localhost:25565

Which will accept client connections on localhost port 25567 and relay the connection to the server at localhost port 25565. This has the side effect of display packets that pass through to stderr.

Connect your Minecraft client to localhost:25567, and a record of the clients actions will be stored to player.log-1, player.log-2 etc. (one file per client connection).

To replay a session:

$ replay localhost:25565 player.log-1
