Open Source ActionScript Games

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.

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.

mapgen2 is a procedural map / island generator intended for games. It focuses on generating continent/island style maps (coastlines, mountains, rivers, etc.) with a vector / polygonal structure rather than a full high-resolution tile grid. Originally written in ActionScript, this tool emphasizes generating aesthetically pleasing island maps with realistic natural features while keeping computational complexity manageable. It supports exporting to SWF (Flash) via appropriate tooling. The most important features I want are nice island/continent coastlines, mountains, and rivers. Non-goals include impassable areas (except for the ocean), maze-like structures, or realistic height maps.

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.

Anodyne is a surreal action-adventure game originally released in 2013 by Analgesic Productions. The 1-Repo is the open source release of the game’s source code, assets, level editor etc, so users can build, modify, or examine the game. The game features exploration, puzzles, a broom as a tool/weapon, top-down rooms, dreamlike narrative and atmosphere, and pixel-art graphics. This is all of the original music source files which you can open in REAPER and play back using the free sfz plugin with some freely available soundfont files. There's more instructions inside! REAPER lets you easily export these projects as MIDI files to use in other DAWs, even if you don't have the original plugins.

Hungry Hero is an open source Flash game developed with the Starling Framework, designed as an educational example for developers interested in Stage3D and GPU-accelerated game development. The game demonstrates how to leverage Starling’s features to create smooth, hardware-accelerated 2D experiences while maintaining cross-device compatibility through Adobe AIR and Flash. It showcases core concepts such as handling textures, sprite sheets, parallax backgrounds, and collision detection, providing a clear reference for building interactive games. The project also integrates advanced techniques like object pooling for performance, bitmap fonts for efficient text rendering, and Starling’s particle system extension for visual effects. Though originally built with the iPad 1 and 2 in mind, it can be adapted to multiple devices by adjusting configuration files, emphasizing the principle of “one code, multi-screen.”

VirtualCockroach is a desktop “pet” application that displays a cockroach roaming around on your desktop. It was developed using Adobe AIR / Flash, includes desktop integration (taskbar icon, system tray, etc.), has various behavioural modes, and includes features like hiding the window, startup animation, etc., mostly as amusement or novelty. Modify the tentacle animation, change from simple png reading to automatic random movement. Update window menu interface, support drag window. Expand the optional range of cockroach sizes, but don't be greedy and be careful that system resource usage is too high.

Boscaceoil is a cross-platform, standalone music tracker designed by indie game developer Terry Cavanagh. Built with Flash, it lets users compose music in a grid-based tracker interface with built-in instruments that mimic the sound of old-school game consoles. It’s great for creating retro game music or experimenting with synthesized tones in a nostalgic interface that feels like a modern homage to classic trackers.
