This is a rewrite of my older game engine, with code dating back to 2007.

• Project Board
• Documentation
• Projects and Examples:
  • FRAG.EXE (First person shooter)
  • Micro Army (2d platformer)
  • Qorpse (2D shooter)
  • Skyroads-inspired racer
  • C++ Usage Example
  • Python Usage Example

• Cross-platform (Windows, Linux, and Mac(wip))
• Multi-threaded (more improvements here soon)
• OpenGL ES-compatible shader-based pipeline
  • Forward rendering w/ multipass lighting
  • Several shaders, including tangent-space bumpmapping
  • Partitioner/culling support
  • Automatic VBO baking of visible areas (10x framerate in many cases)
  • Mesh instance copy-on-write vertex and shader attribute modifications
  • Basic instancing
  • Render-to-Texture
  • Thread-safe OpenGL task handler
• C++ and (wip) Python support
• Multi-layer tilemap system for 2D games
  • Compatible with Tiled map editor
• Python Console
• Shared resource management
  • Animating Sprites
  • Resource management and multiple path search
  • Resource caching
  • Basic create() function for all types
  • Json config for more complex resources
    • Config-based type-resolution and subresources
  • Composite/nested resource suport
  • User-defined resources
• 3D Scene graph
  • World matrix transform caching
  • Static mesh baking (collapse to world space and combine)
  • Tracking/following w/ animation support
  • Node factory supporting user classes
  • Node tags
  • Many 3D model formats supported
  • Blender scene exporter
• Reactive Subsystems
  • Communicate with/between nodes easily by sending/receiving data through named metaobject/json events
  • Each node has a lightweight state machine with signal support
  • User-defined events and states
• State stack
  • User-defined engine states
  • Async loading screens
• Input
  • Multiple controllers
  • Bindings specific to player profiles
  • Button/switch-associated events
  • Switch history for timer-based events and multiple fast press events
  • Activation thresholds
• Animation (code moved to kit)
  • Timer-based keyframes
  • Interpolation/Easing
  • Callback scheduling
• Music and 3D Sound
  • Powered by OpenAL
  • Wav and Ogg support
  • Thread-safe
• Cairo 2D primitives w/ Render-To-Texture
• Pango Font and Text Rendering
• Headless mode for dedicated servers and unit testing

More features will be listed as I add them...
