This is a rewrite of my [older game engine](https://github.com/flipcoder/qor-old), with code dating back to 2007.

- [Project Board](https://trello.com/b/0uh8zbxa/qor)

- [Documentation](https://github.com/flipcoder/qor/blob/master/QorBook.md)

- Projects and Examples:

    - [FRAG.EXE (First person shooter)](https://github.com/flipcoder/FRAG.EXE)

    - [Micro Army (2d platformer)](https://github.com/flipcoder/microarmy)

    - [Qorpse (2D shooter)](https://github.com/flipcoder/qorpse)

    - [Skyroads-inspired racer](https://github.com/flipcoder/bouncingship)

    - [C++ Usage Example](https://github.com/flipcoder/qor/blob/master/src/DemoState.cpp)

    - [Python Usage Example](https://github.com/flipcoder/qor/blob/master/bin/mods/scriptdemo/__init__.py)

## Features

- 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](http://mapeditor.org) 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](https://github.com/flipcoder/kit))

    - Timer-based keyframes

    - Interpolation/Easing

    - Callback scheduling

- Music and 3D Sound

    - Powered by OpenAL

    - Wav and Ogg support

    - Thread-safe

- [Cairo](http://cairographics.org) 2D primitives w/ Render-To-Texture

- [Pango](http://pango.org) Font and Text Rendering

- Headless mode for dedicated servers and unit testing

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