Free mud engine software for linux

Fuzz Engine is an SDL/Mono-based 2D game engine that loads its games from XML so that anyone with a simple text editor can produce their own high-performance games in minutes.

Known problems: the platform game system is still pretty flaky.

Absolut Engine is a news publishing system. It features three-layer access (admin/chief/editor), article posting, editing, and deleting. Absolut Engine includes a powerful image managing tool, a file manager, and a related articles manager.

Rich text editing is provided via a built-in WYSIWYG editor that produces XHTML 1.0 Strict-compliant code. Absolut Engine is easy to extend via module functionality. The provided modules include Discussions, Surveys, RSS Feed, Search Engine Optimization (static/clean URLs), and a message system for better communication between users.

Absolut Engine produces Web-standards-compliant valid and accessible XHTML 1.0 Strict and CSS semantically-correct code.

KoalaMud Game Engine project is a multithreaded MUD server.
KoalaMud is a MUD source base designed around multithreading and stability. On top of this platform, Shadow of the Wheel is evolving to demonstrate its capabilities.
Enhancements:
- Tons of new stuff done here.
- We now have basic rooms support completed, though there are still some additional pieces to be flushed out.
- We also have the first part of the skills system outlined and language support is more flushed out now.
- The network code has been completely rewriten to extract Qt from that loop.
- All input is now processed in the thread pool via ZThread tasks.
- Overall the system seems to be even more responsive now and I have not had nearly as many problems with stability since this code conversion.
- Split commands into multiple command trees that are searched as needed.
- Currently we have standard commands and immortal commands.
- All of the OLC editors have been moved under the olc command tree for simplicity and consistancy as well.
- This also paves the way for aliases later on.
- Also added color marker support.

The CheeseMusic engine is the core to most of the cheesetronic audio tools.
CheeseMusic Engine is a flexible and powerful set of components designed to aid in the programming of audio software.
Main features:
- Very fast fixed point mixing/resampling engine. (tops around 200 voices on my duron 850mhz)
- Support for custom Effect Buffers (and LADSPA too).
- Abstract DSP/MIDI layers with support for ALSA/JACK/OSS/Win32
- Support for synthesis helpers such as envelopes,LFOs,filters,ringbuffers,interpolators,declickers,etc
- GUI-Agnostic support thru "Property Bridges" with GTKmm and QT support (but most support is for Qt)
- Qt widgets for configuring many components, such as:
- Audio/Midi drivers.
- Resampler.
- Effect Buffers/Routing.
- Envelopes/LFO,etc.
- Midi-Input managers, with voice/bank/channel allocation and integration to the mixing engine
- Powerful framework for writing MIDI Synthesizers, as programming at voice level is only needed.

Natrium Engine project tracks groups of parts by letting users define the relationships between parts. Users create definitions for configurations and parts.

These are joined together to form a rule for parts in configurations. When a part is removed from or added to a configuration, all children of that part are also transferred. This has special applications to "living" inventory, or groups of disparate parts that need to be tracked as a group rather than individually.

For example, if a carburetor is made a separate configuration from an engine, then when removing it all parts associated with the carburetor are also removed. A facility is provided for tracking user-defined line-item costs of each part.

The GTK-Qt Theme Engine is a project allowing GTK to use Qt widget styles.
Gtk-Qt Theme Engine behaves like a normal GTK theme engine, but calls functions from Qt instead of doing the drawing itself.
Version restrictions:
- Due to an incompatibility between Qt and the GNOME window manager, some parts of GNOME will not be themed by Qt.
- The theme will run fine under GNOME, but the logout box and window border menus will appear blank.
- It appears that the only way to overcome this bug is by patching Qt itself.

Siriel4 game engine project is a game engine for adventure, arcade, maze-like games.
The main goal of this engine is to provide tools and scripts for easy game creation.
Game creators only write the necessary scenario descriptions for the game in a scripting language (such as Lua) and do not have to care about such low-level details as animation loading, etc.
Main features:
- Lua-5.0 - scripting language support
- DUMB - music and audio support
- Multiplayer
- Terminal support for controlling engine
Enhancements:
- fixed widget system
- removed procedure for separate processing of widget and replaced by flag indicating status of widget
- basic support of room neighbours
- fixed Makefile - include paths
- fixed freeze mode of univers (bug: avatar can move in freeze mode)
- callback function
- avatar can walk through rooms
- fixed processing and displaying things in correct rooms, so they display only in rooms where they are connected to
- fixed collision with object
