    VVVVVV

    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.

    Super Smash FLash 2

    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.

    mapgen2

    mapgen2

    Map generator for games

    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.

    Juicy Breakout
    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.

    Hungry Hero

    Hungry Hero

    Hungry Hero is an open source Flash game built on Starling Framework.

    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.”

    kidware

    Kid safe flash apps packaged in webpages

    Kidware is currently a few flash apps for helping very young kids with learning mouse control, counting and basic sets. I tried to keep as much distraction out of the games as possible, in part, because I want the kids to focus on learning the tech above being amused. Hopefully kids will quickly learn these techniques and then use them to play some more advanced games. Currently, most of the games do not come with sound or instruction so the teacher/adult may need to demonstrate the game. The games are also up on kongregate.com where some of them use that system to track high scores, however, there is a lot more visual spam on that site. More levels and audio are planned for future updates. Open to suggestions for future games. Check out wudiware.com for some of the other projects, like brainstorm browser, which is more for an older audience.
