Mudlet 4.8 - Drag and drop packages, custom cursors, and amazing maps

This is an amazing release that adds drag and drop packages, custom cursors, draggable labels and more! Mudlet is now more powerful than ever for building stunning, modern interfaces for MUDs.

Drag and drop packages

Thanks to Edru, who massively improved Geyser and Userwindows in the last update, you can now drag and drop packages into Mudlet to install them. Pretty simple!

Along with this comes a sysDropEvent, so you can code a custom action when a file is dropped into Mudlet. If you’re a package author, remember you can make use of the sysInstall event to notify that your package has been installed. Enjoy!

Carrion Fields added

This game has put together a seriously impressive Mudlet package and we’re honoured to have them added to Mudlet officially! Double-click on CF in the Connection screen to play :)


Carrion Fields is a unique blend of high-caliber roleplay and complex, hardcore player-versus-player combat that has been running continuously, and 100% free, for over 25 years.

Choose from among 21 races, 17 highly customizable classes, and several cabals and religions to suit your playstyle and the story you want to tell. Our massive, original world is full of secrets and envied limited objects that take skill to acquire and great care to keep.

We like to think of ourselves as the Dark Souls of MUDs, with a community that is supportive of new players – unforgiving though our world may be. Join us for a real challenge and real rewards: adrenalin-pumping battles, memorable quests run by our volunteer immortal staff, and stories that will stick with you for a lifetime.

Adjustable Containers

Edru didn’t just stop with drag and drop – adjustable containers are in as well! What does it mean? It means labels/miniconsoles that you can move around and reposition just by dragging! No code needed.

Try this code in Mudlet:

testCon = testCon or Adjustable.Container:new({name="testContainer"})
testLabel = Geyser.Label:new({x=0, y=0, height="100%", width="100%", color="green"},testCon)

Search within the script

Dicene also added a cool feature – you can now hit Ctrl+F to search within the script only, not your entire Mudlet profile!

He didn’t just stop there either – you can now toggle whenever you’d like to search within variables, default off so it’s quicker:

CP437 encoding now supported

Thanks to SlySven, the CP437 encoding is now supported. Along with a custom font, Medievia makes use of this to draw amazing custom maps :)

Custom cursors

Yep, custom cursors are here! Curious? Download, drag, and drop this demo package into Mudlet to try all the cursors out :)

Big thanks to Edru for adding these in.

New API features

gcms added MXP as another format that you can get data / events from, just like GMCP. Check it out!

demonnic did a pass over the table functions – table.contains() can now check within multiple nested tables, and table.collect(), table.n_collect(), table.matches(), table.n_matches() to make working with tables easier.

Thanks to Edru, you can now manipulate the syncing of a module with enableModuleSync(), disableModuleSync(), and getModuleSync(), and add/edit the Scripts as you see them in Mudlet with enableScript(), disableScript(), setScript(), getScript(), permScript(), and appendScript().

Edru also improved on the userwindows – you can now choose whenever they should be popped out or docked at start, and if docked, which area should they be in. Autodocking while dragging can now be disabled, too!

A few more improvements are also present – see the full changelog below.

Geyser:show() fixed

As mentioned two months ago, we’ve fixed an issue where you could still :show() the child of a hidden container. If your UI relied on this broken behaviour, make sure to update it!

Script editor sizes

Alias/trigger/script editors are no longer huge by default, and they’ll remember their sizes as well. Thanks to dicene for covering this off!

Polish translation ⭐

Big thanks to mwarzec for translating the entirety of Mudlet into Polish! In his own words, it was possible thanks to:

home.. sweet home.. and no reasons to go outside..


Did I miss 4.7?

We skipped 4.7 because that was the April Fools version ;)
