Flixel vs Genome2D

Ports are available for Objective C, C# (XNA), HaXe and Monkey X.

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.

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.

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.

• 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

Flixel Power Tools provide a set of classes and APIs that provide more functionality.

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

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.)

Has access to direct draw features so you can make you own rendering structures (scene graphs etc).

Automatically batch geometries with dynamic batching techniques (by using constant buffers).
