On Thursday, we will have an excellent visitor, Tom Rothamel, the creator of Ren'Py (https://www.renpy.org) speaking about the design of languages for Ren'Py. (See also https://en.wikipedia.org/wiki/Ren%27Py.)
Ren'Py is a visual novel engine---used by thousands of creators from around the world---that helps you use words, images, and sounds to tell interactive stories that run on computers and mobile devices. In this talk, the lead developer of Ren'Py will describe the various languages that are the main way that creators interact with Ren'Py; especially two of the languages: The script language that is the main way that users interact with the engine to create games, and the Screen Language that's used to to present user interfaces. We'll cover the how the languages have been designed for the needs of the visual novel medium, and how they are intended to address creators that have not been formally trained in the art of programming.
