This month, we have the first of a new kind of sponsor article. In this series, I’m going to try to focus on Ren’Py development, and the topics that come naturally each month as I create and support Ren’Py.

A couple of months ago, I received a request from a sponsor who wanted to see if there was a way for Ren’Py to indicate a player’s progress through a visual novel, both through the VN as a whole and through a single chapter inside it.
This turned out to be a harder problem than I thought it would be, but after an attempt last month tha...

I'm happy to announce Ren'Py 7.3.5, the latest in a series of releases that continue to maintain Ren'Py 7.3. This release fixes the compilation of iOS projects, and adds a button that accesses the audio directory to the launcher.

I'm happy to announce Ren'Py 7.3.4, a further patch to Ren'Py 7.3. This fixes two major graphical glitches, and also adds the ability to pass "[prefix_]" to image names everywhere, rather than only in styles. The graphical issues are pretty major and can manifest in reasonable circumstances, so I recommend everyone upgrade from 7.3.3 to 7.3.4.

In the 15 years I’ve been developing Ren’Py, I’ve given talks to fan conventions, school clubs, and academic settings. When I give a talk, I use a presentation framework that runs inside Ren’Py itself. Doing so makes it possible to intermix static slides with examples of the Ren’Py script running.
