When comparing Flixel vs Genome2D, the Slant community recommends Flixel for most people. In the question“What are the best 2D game engines?” Flixel is ranked 20th while Genome2D is ranked 50th. The most important reason people chose Flixel is:
Ports are available for Objective C, C# (XNA), HaXe and [Monkey X](https://github.com/devolonter/flixel-monkey).
Ranked in these QuestionsQuestion Ranking
Pro Many ports available
Ports are available for Objective C, C# (XNA), HaXe and Monkey X.
Pro Built-in pathfinding and following
Pathfinding just means figuring out how to (or if you can) get from A to B. FlxTilemap has a function FlxTilemap.findPath() which returns a FlxPath object, which is just a collection of "nodes", or FlxPoint objects.
Pro Camera system for split screen
Create effects like "split screen" views, or "picture in picture" style displays, or even mini-maps with FlxCamera. Each camera is an independent display object, with its own zoom, color tint, rotation, and scaling values.
Pro Record and play back replays
Replays are essentially a list of what keyboard keys were pressed, and what mouse inputs were given, during a specific time frame. Because Flixel is largely deterministic, you can use that information to recreate a gameplay session that someone else recorded, as long as you have the same SWF.
Pro Basic features provide a solid foundation
- Display thousands of moving objects
- Basic collisions between objects
- Group objects together for simplicity
- Easily generate and emit particles
- Create game levels using tilemaps
- Text display, save games, scrolling
- Mouse & keyboard input
- Math & color utilities
Pro Flixel Power Tools extend the functionality
Flixel Power Tools provide a set of classes and APIs that provide more functionality.
Pro Used to create Canabalt, game that started endless runner genre
Pro Lightning fast
It's the fastest gpu-based framework out there for flash. It's beautifully optimised. It has very low rendering latency, low level OpenGL calls that other tech simply cannot do (ie Unity) due to Stage3D, and thus can render a lot more data quicker
Pro Cross-platform mobile, desktop and web
Supports Windows, Mac OS X, Linux, iOS, Android, Web and native Flash.
And with the HTML5 export, it also potentially supports development for the Wii U :)
Haxe is a strictly typed programming language that saves development time but still compiles high performance executables, and can build for tons of different platforms (flash, c++, html5, java, c#, etc.)
Pro Access to direct draw features
Has access to direct draw features so you can make you own rendering structures (scene graphs etc).
Pro Automatic dynamic batching
Automatically batch geometries with dynamic batching techniques (by using constant buffers).
Pro Component based architecture
Con Development has stopped
Seems like development for Flixel has stopped. The last commit on all of the branches of it's Github repository are from 2011.
Con Poor performance on mobile
Con Lacks documentation
The API documentation is minimal, there's not many tutorials and the ones that are there are very small and only cover the basics. If you want to learn how to properly use it, you have to ask the community or read the source code and figure it out.
