clayoteReleased version 0.19.2 of <a href="https://peoplemaking.games/tags/Lisien" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Lisien</a>, the time-traveling rules engine for systemically complex life simulation games.This release adds the ability to run Lisien with no database, nor any files open at all. It's mainly useful for testing Lisien itself--but could be of use in testing your game, too.It also fixes the string store, so you can change what strings are in it within the Python interpreter, if you want.Get it in your Python interpreter: <code>python -m pip install -U lisien elide</code>Or on Itch: <a href="https://clayote.itch.io/lisien/devlog/932346/v0192" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://clayote.itch.io/lisien/devlog/932346/v0192</a><a href="https://peoplemaking.games/tags/gameDev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#gameDev</a> <a href="https://peoplemaking.games/tags/customEngine" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#customEngine</a> <a href="https://peoplemaking.games/tags/lifeSim" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lifeSim</a> <a href="https://peoplemaking.games/tags/lifeSimulation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lifeSimulation</a>

clayoteReleased version 0.19.1 of <a href="https://peoplemaking.games/tags/Lisien" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Lisien</a>, the time traveling rules engine for making life sim games.This is a bugfix release. The biggest bug was that big rules weren't resetting the time at the end of planning blocks, which meant that if you had a big rule that set a lot of things to traveling, such as the <code>pathfind</code> example, they would wait for each other to finish travel before starting their own, which would take a really long time.Get it in your <a href="https://peoplemaking.games/tags/Python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Python</a> interpreter: <code>python -m pip install --upgrade lisien elide</code>Or on Itch: <a href="https://clayote.itch.io/lisien/devlog/928348/v0191" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://clayote.itch.io/lisien/devlog/928348/v0191</a><a href="https://peoplemaking.games/tags/lifeSim" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lifeSim</a> <a href="https://peoplemaking.games/tags/lifeSimulation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lifeSimulation</a> <a href="https://peoplemaking.games/tags/gameDev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#gameDev</a> <a href="https://peoplemaking.games/tags/customEngine" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#customEngine</a>
