Pros
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 Can create portable native applications
Polycode uses Lua and C++ to create native applications for Windows, Mac, and Linux. Mobile platforms are planned for the future.
Pro Free and open source
Polycode is free and open source (released under the MIT license). The source code is freely available on GitHub.
Pro IDE for 3D editing
Recently, the editor and its integrated tools have been released in compiled form. Features coding and scene editing in one application.
Pro C++/Lua
Polycode is distributed in a C++ form as well as with IDE. And there's an additional LUA-based scripting system.
