Momoko is a generic, object-oriented, modular, extensible environment for creating multi-user environments. It is suitable for writing MUDs, servers, and community-based Web sites. It is written in pure Java and supports Java and Python as internal scripting languages. Momoko provides facilities for organizing objects into tree-based hierarchies, orthogonal persistence, a transparent distributed objects system, remote access to source code and user files via WebDAV, a telnet-enabled shell for manipulating the object database, and an integrated build process which can be triggered remotely.
Trebuchet Tk is a MUCK/MUSH/MOO GUI client written entirely in TCL/Tk. It supports both Unix/X11 and Windows, and includes powerful scripting, triggers, hilites, macros, quickbuttons, keybinds, etc. that you would expect from a good MU* client. It also supports MCP simple-edit, and GUI dialog packages for MOO and FBMUCK6. For Muck users, Trebuchet also supports intelligent colored editing of MUF and MPI programs.
ymusk stands for Yenzie's Mush Klient. It is a mush client written in Perl, and it is built around the Net::Telnet and Tk modules. It is meant to be a simple program which is easily customizable. Its features include logging, macro definition, speech filters, command history, and ANSI colors.
JamochaMUD offers Unicode, plug-in, and multi-language support (8 different languages) to allow a more enjoyable MUCKing/MUDding experience. It features command history, synchronized window controls, experimental SOCKS 5 support, and greatly improved ANSI colour support. It plays nice on Unix systems, supports a wide range of MU*s, and also includes emulation of some TinyFugue editor controls. JamochaMUD includes classes that may be easily reused in other Java applications.
Metacosm is a framework for computer role playing games in Java. An example called ZHeroeZ is also provided. Some of the project's objectives are object oriented design, world persistency (all actions should have a long term impact on the world), coherent time management (time is the same for everybody in the same world), a graphical editor, and choice in client user interface. All creatures can be player or AI controlled by design.
