We are alive again as of July 2010!!!!

The glaze google group is now clear of spam - post questions there, or feature requests here under the 'Issues' tab

New blog coming soon

Starting with a reorganization & spiting the project into several parts:

• Core Physics Engine + Testbed
• General Demos
• Game Engine
• Game Level Editor (2011)

I'm looking for anybody to help out, especially with the level editor.

Engine Requirements Overview:

• Very Large Scene management
• 50,000px x 50,000px
• 100,000's shapes
• World Objects (other bodies, joints, force generators)
• Optimized Broadphase
• Line of sight
• User Input
• Scrolling
• AI

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

Development

Apart from the conversion from C to AS3 and OOP, many adaptations have be made to tune the engine for the performance characteristics of the AVM2. In summary:

• The original relies heavily on memory operations & copy/update arrays for many things - especially contact lists. Array operations (splicing, adding/removing elements) is expensive in this situation. All these arrays were replaced with linked lists
• Many function calls have been inlined. The makes the code a mess, but has a significant performance benefit.
• Object pooling. Once create, the most important core objects are all recycled via shared pools.
