QuickB2

QuickB2 is a complete abstraction of Box2D, providing grouped hierarchies, extensible classes, and event-driven callbacks. The high-level interface enables developers to create physics simulations that are impractical to write using Box2D’s API alone.

Some features:

• Soft-bodies.
• Top-down car physics.
• Friction in z-direction (top-down friction).
• Event-driven through revent.
• Retain mode that doesn’t require destroying/remaking objects.
• Extensible architecture.
• Nested hierarchy system similar to Flash’s display hierarchies.
• Cloneable objects.
• Highly customizable immediate-mode rendering for both debug and production purposes.
• Hooks for integration with any typical retain-mode-type rendering engine (e.g. the Flash display list).
• Various debugging tools including visualizations, mouse dragging, warnings, notifications, asserts, exceptions, and runtime GUIs.
• Pixel-based units.
• AABB and circular bounding representations.
• Easy low-level access to Box2D API in case of emergency.
• Large suite of “stock” functions and classes to address common needs.
• Individual polygons may be concave and have any number of vertices.
• All kinds of joints, including built-in spring joints.
• Physics world is completely changeable within contact callbacks.
• WYSIWYG editing environment for Flash CS5.
• Built-in system for handling your game loop and time steps.
• Easy API for beginners – lower-level optimizations and tricks available for advanced users.
