bfxr
Flash + AIR sound effects generator. Based on Sfxr.
The bfxr project by increpare is a sound-effects generator tool originally built using Flash + AIR, based on the earlier Sfxr project. Its purpose is to enable users, especially game developers and sound designers, to quickly generate retro, 8-bit/“chiptune” style sound effects (“bleeps”, “booms”, “zaps”, etc.) without deep knowledge of audio signal processing. It offers an interactive GUI through which you can tweak many parameters (oscillators, envelopes, filters, etc.) to sculpt custom sound effects; you can preview in real time, export, and iterate. The project includes libraries, HTML templates, and both ActionScript and JavaScript code. It has been well-received (over a thousand stars), but as of 2025, it has been superseded by a newer version called bfxr2, which is a JavaScript reworking of the original. -

VVVVVV
The source code to VVVVVV
From the creator of Super Hexagon, VVVVVV, the hit 2010 indie platformer, now available on android and iOS! Winner of Indiecade's 2010 award for Most Fun/Compelling Game. There are two versions of the VVVVVV source code available, the desktop version (based on the C++ port, and currently live on Steam), and the mobile version (based on a fork of the original flash source code, and currently live on iOS and Android). If you’re looking for the game’s text, that’s mainly (but not entirely) in the Scripts.cpp and TerminalScripts.cpp classes. These functions basically load data into a very simple script parser that controls cutscene logic. All the actual levels in the game are hardcoded in huge arrays generated with a map editor, which exports the levels in source code. Since the 2.0 update, the Windows, Mac and Linux versions of VVVVVV have featured a powerful and easy to use level editor. -

FileReader
A FileReader polyfill for Internet Explore and Safari using Flash
FileReader is a polyfill library combining JavaScript and Flash (SWF) to mimic the HTML5 File API in older browsers (notably Internet Explorer and Safari versions that did not support File API fully). It overlays a transparent Flash SWF over a DOM element to allow users to select files, then exposes a .files attribute etc., so that client-side file reading behaves more like modern standard. It is unmaintained now, since File API support is widespread. -

SignalCommandMap
Robotlegs extension to facilitate the use of AS3-Signals with Robotleg
signals-extensions-CommandSignal is an ActionScript 3 extension that integrates Robotlegs and AS3-Signals frameworks to provide a cleaner, strongly typed alternative to traditional Flash Events in application architecture. Robotlegs uses events as the communication mechanism between models, services, and commands, but this project replaces that system with the more robust and object-oriented AS3-Signals. By combining the two, developers can eliminate the ambiguity and string-based event registration common in standard event-driven patterns. The library introduces the SignalCommandMap, a utility that allows developers to map Signals to Commands, enabling commands to trigger automatically when a Signal’s dispatch() method is called. This extension also creates a SignalContext, an enhanced MVCS context that manages Signals alongside the traditional Robotlegs maps. -

SoundAS
A modern lightweight sound manager for AS3
SoundAS is a modern and lightweight sound management library for ActionScript 3, built for both Flash and Adobe AIR applications. Its primary purpose is to simplify audio playback, making it easier to transition between sounds, manage sound effects separately from looping music, and handle complex sound interactions. The library provides a clean API that supports chaining, allowing concise and expressive sound control in just a few lines of code. It includes built-in support for seamless looping, volume fading, tweening, and grouping of sounds, making it highly useful for game development and multimedia projects. SoundAS also offers a modular structure, enabling developers to use individual SoundInstance objects directly without needing the full system. With a permissive license and active examples, it is designed to be straightforward, flexible, and powerful for managing audio in ActionScript projects. -

Standing Wave 3
Flash ActionScript3 dynamic audio library
Standing Wave 3 is an ActionScript 3 audio library that provides high-level control over the Flash Player’s SampleDataEvent API for streaming audio output. It builds on the foundation of Standing Wave 2 but has been extensively refactored, with its core sample storage and manipulation routines rewritten using Adobe Alchemy for significant performance improvements. Originally derived from the audio engine used in the Noteflight Score Editor, the library allows developers to combine and chain together audio sources, filters, and sequences to create dynamic, real-time sound experiences. Supported audio sources include MP3s, WAV files, and algorithmic generators, while filters enable effects such as echo, equalization, and envelope shaping. The system is flexible enough to handle complex timing sequences of audio, making it suitable for advanced audio applications or interactive projects. -

as3delaunay
Delaunay triangulation and Voronoi diagram for Flash Builder 4 project
as3delaunay is an ActionScript 3 library that provides an implementation of Delaunay triangulation and Voronoi diagram generation. It is based on the well-known work of Raymond Hill and offers developers an efficient way to create and manipulate geometric structures for use in Flash and other AS3-based environments. The library enables users to generate Voronoi diagrams from a set of input points, allowing applications such as procedural map generation, image segmentation, and spatial partitioning. By handling complex geometric relationships automatically, it simplifies the process of building interactive or data-driven visualizations. The project emphasizes performance and mathematical accuracy while maintaining readability for developers working in ActionScript. Its codebase serves as a reliable foundation for anyone implementing geometry-based algorithms or graphical systems within AS3 projects. -

Super Smash FLash 2
Super Smash Flash 2 is the most must-play battle game with 28 classic
SSF2 Fan Club: https://www.facebook.com/SuperSmashFlash2FC/ Play SSF2 Online: https://www.freegames66.com/fighting/super-smash-flash-2/ Nice news for those who love Super Smash Flash game, the upgraded version is better and better with an extra 3 playable characters to swell the ranks too (Marth, Zero Suit Samus and Chibi-Robo). Super Smash Flash 2's gameplay is very similar to the official Super Smash Bros. However, the most interesting feature of SSF2 is that character's health is measured by a damage percentage counter. It means a character is attacked, the damage will be accumulated, and percent value gets high. The controls of Super Smash Flash 2 are also different from the previous version. Make use of WASD keys to move Player while the arrow keys are used to control second player. The O and P keys still remain in P-1's possession, the P key for standard attacks, the I key for shield, and the 1 key for taunting. -

Juicy Breakout is a demo/example game created by grapefrukt (Martin Jonasson & Petri Purho) to explore and demonstrate “juiciness” in game feel, how small visual, animation, and feedback effects make a game feel more responsive, alive, and engaging. It’s built in ActionScript (Flash) and uses grapefrukt’s own libraries (grapelib) to handle game framework, input, rendering, etc. The demo showcases a Breakout-style (brick-breaking) game but with extra polish, effects, easing, cascading animations, sound, and visuals that exaggerate response so you feel every bounce, paddle movement, and collision. The source is under the zlib license, allowing free use and modification.
