What is Mudlet?

Mudlet is a platform for gaming and enhancing game-play primarily with MUDs.
Mudlet provides a toolkit and supports a wide variety of protocols for players and creators to tailor an immersive game-playing experience. MUD creators can use Mudlet to add visual flair or build features into their text games. MUD players can utilize the Mudlet toolkit to script and automate parts of their gameplay or add their own visual customization for game data.

Outside the realm of MUD games, Mudlet has even been used to provide automation and features in 3D games which support in-game chat and a Telnet or similar server-console protocols.

What are MUDs?

MUD (/ˈmʌd/; originally Multi-User Dungeon, with later variants Multi-User Dimension and Multi-User Domain),[1][2] is a multiplayer real-time virtual world, usually text-based. MUDs combine elements of role-playing gameshack and slashplayer versus playerinteractive fiction, and online chat. Players can read or view descriptions of rooms, objects, other players, non-player characters, and actions performed in the virtual world. Players typically interact with each other and the world by typing commands that resemble a natural language. – Wikipedia

It’s the type of game you’ll fall in love with for its ability to tell a story, have epic combat raids, devious politics, or just have a grand time with your new friends.

4.16 – easier map labels, map autosaves, and scriptable settings

Summer is around the corner in the Northern Hemisphere… and so is a new update of Mudlet! It brings easier map labels, map autosaves, and scriptable settings.
Easier map labels
The previous version of Mudlet had a map label form that was hard to use. This version has a much simpler map label experience, thanks to Delwing’s efforts.

Map autosaves
Profile autosaves, after they had been introduced, largely eliminated losses of unsaved scripts when Mudlet was unexpectedly shut down. Map autosaves are here to do the same thing: even if you don’t save your map by hand, Mudlet will save the map for you in the background on a regular basis, so you don’t lose your work.
Just like profile autosaves, this feature is easy on the disk space as it keeps just one autosaved copy of the map around.
Scriptable settings
This one has been on the wish list for a good while – the ability for scripts to adjust Mudlet’ settings to their liking. This is now here by the way of a setConfig function. The initial implementation of this feature by ktunkiewicz and Vadi has options for adjusting the map view, enabling MSDP, and various special options. More settings will be added over time.
Release automation
A lot of effort this release was put into automating releases since the process was far too unwieldy and complicated. Delwing got his elbows out, and created a plugin to synchronise github releases to Wordpress, which cut down on a lot of overhead. FloXire automated US English translation text generation, Vadi tweaked changelog generation to work for releases as well as PTBs, and keneanung restored connectivity between Github and mudlet.org. All of these improvements make releasing much easier!
While we’ve made great strides in this area, there is still some work to do, so if you can help out – join in!
