Evennia 0.7 was just released. Evennia is a MU* creation library in Python. People here on MU soapbox might be most familiar with it being the engine running Arx.

There are a ton of updates and fixes. Many are technical and of more interest to those already into Evennia; here are some of more general interest:

  • Evennia separates Player objects from Character objects in that the former is an OOC entity that can puppet one or more of the latter. The name Player was a source of some confusion since this is used differently in other code bases. Player has now been renamed to Account to make its function clearer.
  • Evennia's in-built website now uses our own theme and bootstrap under the hood to make it easier to modify as well as rescale it better on mobile devices (webclient is not updated at this point).
  • Shared logins between webclient and website, with the ability to log out of each independently of the other if so desired.
  • Prefix-ignoring - All default commands are now renamed without their @-prefixes. Both @examine, +examine or examine will now all point to the same command. You can customize which prefixes Evennia simply ignores when searching for a command. The mechanic is clever though - if you create a command with a specific key "+foo", then that will still work and won't clash with another command named just "foo". This idea was borrowed from @faraday's Ares system.
  • Easy pause mechanisms using yield statements directly in Command code (just do yield 10 in your command code to have it pause ten seconds without blocking anyone else). You can also do retval = yield "Do you want to accept?" and have the command pause (non-blocking) for the player's input before continuing.

New contribs (optional plugins) (selection, new since 0.6 but many have been available on master branch for a while):

  • The optional In-Game-Python contrib by Vincent le Geoff might be of interest to people here. It allows for coding and scripting in-game using full-fledged Python to make events and triggers. It's not a safe softcode-style language (you have the full power of Python which is not good for untrusted users) but is intended for trusted builders to make complex scripting from the command line.
  • Wilderness/maps - Creation of dynamic or static maps based on ascii-maps for dynamically creating rooms and to show when moving around. (titeuf87, Cloud Keeper)
  • Full turn-based combat system, meant to expand for a desired system (battlejenkins)
  • Alternative Unix-style command base for Evennia, for those that prefer to enter commands like you do on the unix command line (with --flags etc) (Vincent le Geoff)
  • Multidescer, which together with Evennia's nick replacement system can be heavily customized in-game (me).
  • Mail - a @brandymail-style in-game mail-system (grungies1138)
  • Clothing system, for layered outfits adding to the wearer's desc when worn (battlejenkins).

... And much more. See the release post on the Evennia mailing list for gritty details.
