Open Source ActionScript Animation Software

DragonBonesAS is a skeletal animation framework for ActionScript 3 and Flash, designed to simplify the implementation of complex 2D animations. It separates the animation data from display logic, allowing developers to reuse assets, blend animations, and reduce draw calls. DragonBones supports the creation of character rigs, timelines, and inverse kinematics, making it popular in Flash-based game development.

The public repository for GreenSock’s ActionScript 3 animation libraries (such as GSAP’s TweenLite, TweenMax, and LoaderMax), widely used for creating rich animations in AS3 projects. Public repository for GreenSock's ActionScript 3 libraries like GSAP (TweenLite, TweenMax, etc.) and LoaderMax. For AS2, see the GreenSock-AS2 repository and for JavaScript, see the GreenSock-JS repository. LoaderMax for managing asset loading. Well‑documented and highly modular libraries.

compiler for a Pascal like language that build Flash animation (SWF) FlashPascal2 is a more advanced free compiler availabe at http://flashpascal.execute.re/

An advanced, plugin-based rich media and 2D vector graphics rendering library, capable of rendering diverse vector-graphics formats to customizable output targets.

Blit sprites to a BitmapData with this simple blitting library in actionscript3. It can mirror a spritesheet across the x-axis for half the load time, trims the rectangular regions of each frame to only include the pixels that matters, and supports pre-rendered rotations.

Flint is an ActionScript 3 particle engine designed for creating rich particle effects in Flash and Flex applications, providing tools for animations like fire, smoke, and explosions. This first tutorial will introduce the basics of Flint through a project to create a snow effect. Our effect will be snow flakes drifting down the screen. Each snow flake will be a particle in our particle system. If you want to see the final effect, scroll to the bottom of the page. This tutorial works with version 4.0.0 of the Flint library. This example creates a 2D particle effect. For 3D particle effects the principles are the same but you use a 3D emitter and 3D behaviours. First create a new Flash file (Actionscript 3). Set the stage size to 500 pixels wide and 400 pixels high, set the frame rate to 30 fps and set the background color to black.

LMC_by_alexiskappa is an educational/fun program to view and learn the Little Man Computer concept in action. Little Man Computer models the von Neumann architecture, which has the basic features of a computer. Just enter your instructions/data inside the boxes. Remember that commands are three digit numbers with the first number being the instruction and the next two digits being the memory address box. LMCv1_by_alexiskappa has the general instructions displayed. Just write your commands/data inside the boxes 00-99 [MEMORY] and then click on the "RUN" button. "RESET" clears the contents of the boxes. LMCv2_by_alexiskappa has a simple animation, showing the order of each step. Just click the button "Animation OFF" to enable it, before clicking the "RUN" button. Easter Egg: Try adding in box 00 the number 601 and in box 01 the number 600. After a while, the infinite loop will be detected! VirusTotal: baada04323a708c6821739f661fc2c4e6294037b3d18c0408ecba7b4d3d71ff5

SemanticNet4Web is the library to visualization semantic nets for web. This library is open source project and the part of Open Semantic Technology for Intelligent Systems (OSTIS).

Zoë is an open-source tool in the CreateJS suite that enables illustrators to generate spritesheet images and animation frame data from SWF files, facilitating seamless workflow between Flash authoring and HTML5/EaselJS animation. Zoë is designed to work with any AS3 SWF file version 9 or greater. It's best practice to have all your animations on the root timeline, and use labels to identify your different animations or frames. To begin, simply drag a swf file into Zoë, and click Export to create a SpriteSheet. Zoë and Easel support custom registration points on images. To define one, simply place an empty clip on your timeline labeled registrationPoint. If needed, you can also define multiple points per file.

Flump is a toolchain for converting Flash timeline animations into lightweight runtime formats suitable for games. It allows artists to design animations in Adobe Flash (now Animate) and export them for playback in game engines using ActionScript, Java, or other runtimes. This helps maintain smooth vector animations with minimal performance cost, particularly for mobile and web games.
