There are some great demos that run smoothly in canvas capable browsers and very smooth in Chrome.

Demos of Haxe Sandy:

Sandy was actually the first open source 3d engine in flash, maybe this will be a trend building in haXe for export to flash and javascript?  It certainly looks like a great start and would make a very nice platform for 3d on the web allowing Sandy or other flash libraries to run in Flash and Javascript by writing in an abstraction platform like haXe. Other libraries like Motor2, Physaxe, haxe3D, PureMVC and more have haXe versions. Still very experimental but a possible need when Flash and canvas are both in the market in the future.  Right now it is still all Flash.

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.
