Box2dFlashAS3 has been updated to version 2.0 complete with ragdolls and Theo Jansen walkers ala APE fame.

Nicolas Cannasse, a virtual machine genius (maker of MTASC compiler, Neko and haXe (haXe compiles to target flash 6-9 but really only flash 9 is used anymore unless you are making banners)) released the Physaxe 2D Physics kit for haXe today.

It is heavily based on Glaze (demos) and Box2D which the Motor2, Glaze and Box2DFlashAS3 physics kits are all based on. Box2D is a great C++ 2D physics engine, it is simple which lended itself to being ported to AS3 quite easily. It is also a testament to AS3 that C++ kits are being ported into the language, not once, but many times. Also C ports like Chipmunk and other signs point to == AS3 is of fun.

Physaxe is quite amazing you must see the demos (very similar to Glade demos), it will get the inspirational wheels turning in your idea machines.

2D Physics in Flash and AS3 are extremely hot and can be used for many, many things from game development to promotions to simulations to user interface or visualizations and even modeling natural systems. It is nice to have a port of Box2D and similar to glade capabilities with Chipmunk like Glade has.

A game and physics engine for Flash including:

  • Rigid Body Dynamics
  • Scene management
  • Line of sight
  • User Input
  • Scrolling
  • AI

Core parts of the physics solver and collision system are based on the C physics engine Chipmunk

Notes about Physaxe:

Physaxe is a 2D Rigid Body Library written in haXe. It’s been highly optimized for the Flash 9 Player, with the best optimizations available.

Physaxe is based on several existing physics engines, mainly :

  • Box2D, the reference open source physics engine
  • Glaze, an AS3 engine which is a port of Chipmunk, itself based on Box2D

Physaxe features are :

  • rigid body consisting in several shapes
  • shapes supported are circles, segments (with rounded edges) and arbitrary convex polygons
  • customizable broadphase (currently bruteforce and y-sorted list are available)
  • island resolution and sleeping (allow ~0 CPU to be spent when groups are sleeping)
  • constraint solver based on Box2D sequential impulses
  • customizable body properties, such as linear/angular friction and maximized motion

Updated list of physics engines are like this:

AS3 3D Physics Engines (Open Source)

AS3 2D Physics Engines (Open Source)

haXe 2D Physics Engines

Get your game on! It is best to get them out early and often. I need to take my own advice.

Drew Cummin’s FOAM is a great flash as3 2d physics package that can be integrated quickly and get started with realistic physics in 2d flash apps and games. I have been playing with this since FOAM’s release last week and putting together some tests to show, comparing with APE and really looking forward to polygonal labs Motor Physics to add there.

Three excellent physics engines (FOAM, APE and Motor Physics) for flash in AS3 already. Basically at flash9 player/avm2 market saturation (it is now available to develop on in over 94% of market) is showing the power of the ES4/Javascript2 based Actionscript3 language and how it is inspiring developers to new levels of interest/inspiration. Then again haXe can target them all but I digress.

FOAM was recently released but the author Drew Cummins is showing very good support for the toolkit and released a plethora of goodins to support this great kit, bug fixes, samples, docs and some realistic physics demos as well as in depth walkthrough of creating a force generator and comparison of the Euler and RK4 equations used in that process and their differences (Euler being less correct due to the factors of the platform and intervals and environment, RK4 more correct but more expensive to run)

If you are developing realistic physics in flash games or apps this toolkit is a great source of inspiration.
