# AdamAtomic/flixel

flixel is a free Actionscript (Flash) library that I distilled from a variety of Flash games that I've worked on over the last couple years, including Gravity Hook, Fathom and Canabalt.  It's primary function is to provide some useful base classes that you can extend to make your own game objects.

## What it is
Flixel is a free, open-source 2D game library written entirely in ActionScript 3 for making Flash games. It provides base classes for game objects along with collisions, tilemaps, particles, cameras, pathfinding, replays, and input handling.

## Use cases
- make a 2d flash game in actionscript
- build retro-style pixel games for the browser
- create tilemap-based platformer levels
- add particle effects and collisions to a flash game
- make split-screen camera views in a game
- record and play back gameplay replays
- learn game programming with a simple game library

## When to choose
- you are building 2D games targeting the Flash Player in ActionScript 3
- you want a lightweight, easy-to-learn library with collisions, tilemaps, and cameras included
- you are maintaining or studying legacy Flash games built with Flixel

## When to avoid
- you are starting a new game today, since Flash is deprecated and the library is unmaintained
- you need a modern platform like HTML5, mobile, or desktop targets
- you need 3D rendering or a full modern game engine

## Facets
- artifact type: library
- maturity: abandoned
- function: game-engine, graphics, animation, simulation
- domain: cross-platform
- platform: browser
- tags: 2d-games, retro-games, tilemaps, particles, flash-player, game-library, game-development, flash, actionscript
