Flixel is a free, open-source game development library written in ActionScript 3 originally for Flash, created by Adam “Atomic” Saltsman. It provides a lightweight yet powerful base framework to build 2D games: handling rendering, input, collisions, tilemaps, particles, cameras, etc. It was designed to be easy to learn and extend, useful both for simple arcade style games and more elaborate ones. It has been used for many indie / Flash games (including commercial and contest-nominated ones), and its design emphasizes object recycling, simplicity, utilities, and using free or low-cost tools to create games.

Features

  • Displaying and managing thousands of moving objects efficiently using sprite batching / simple display logic
  • Basic collision detection between game objects, including bounding rectangles and pixel-level where needed
  • Grouping of objects (object containers/groups) to simplify bulk operations (update, draw, destroy)
  • Particle generation / emission system for effects like explosions, smoke, magic etc.
  • Tilemap support for levels: tile‐based maps, scrolling, level rendering, etc.
  • Support for mouse & keyboard input, text display, save games, scrolling, color & math utilities; also advanced features like replay recording/playback, interactive debugger, object recycling, camera system, path following
