Awesome RenPy

A curated list of awesome goodies for RenPy visual novel engine. Originally this started as me dumping my bookmark folder, but since this accrued some interest, I decided to make this more of a thing. Things that were known to be obsolete at the time of writing -- which happens relatively often in the RenPy land -- did not make it into this list unless they were otherwise significant or were the only example of their kind.

Who am I kidding, this will languish in obscurity like every other attempt to produce an index of these things...

Frameworks

Pieces of code big enough to be called libraries.

General

• Console - An in-game console for the player to use (i.e. distinct from the built-in developer console). Not well documented at all.
• DynamicSpriteManager - A high-level system for easily defining and compiling the RenPy native LayeredImage. Given a directory of images, it will automatically scan and categorize those images for use in a mix-and-match style sprite declaration language based on filenames. Documentation inline with code.

Device imitation

• Candella - "Candella is a fork of the AliceOS framework, a Ren'Py framework that provides an operating environment to visual novels. This operating environment includes utilities, classes, and other code that lets developers and players write and use apps designed for the system." To put it less opaquely, this imitates a full window system with "applications" inside RenPy.

Extra content

In a classic Japanese title, these would go into making the contents of an "Extras" menu.

• GalleryPlus - Extends the functionality of RenPy's built-in Gallery class. Allows looping images, pages, navigation buttons.
• renpy-gallery-inject - Self contained gallery screen, and code to allow the screen and functionality to be patched into existing games without changing their code in any way.

• renpy-achievement - A screen to display an XBox-like achievement popup. Does not actually interact with any achievement backend, but the builtin one should serve.

Cookbook

Most useful RenPy code comes in the form of code snippets, examples, and other small pieces, rather than a well-packaged library. As such, many of these links link to Gists, forum posts, and other such locations wherein a given code snippet is presented in context.
