#NGEngine

NGEngine by Nativ' Games is a C++ 2D/3D Game Engine, with the minimum of dependencies:

• OpenGL 3.1: A low-level graphics library
• Glew
• Glm (mathematic library designed for OpenGL programs)

The examples use the following libraries:

• SDL 2.0: create the window in which the OpenGL context is displayed
• SDL_image_2.0: support for png/jpeg images

#Folder Structure

• /include: contains the .h files of ngengine
• /src: contains the sources of ngengine (cpp)
• /externals: contains the external libraries: glm
• /build: contains compilation files (linux makefile)
• /bin: contains the ngengine library and the examples executables
• /examples: contains the sources of the examples
• /resources: contains the resources for the examples
• /tests: contains the unit tests
• /.travis.yml: configuration of the compilation to provide continous-integration (cloning this project on a VM, installing the dependencies, compiling the project, compiling the tests, launching the tests.

#Library Structure

• Collision: the collision shapes (3D BoundingBox for instant, in the future 2D/3D AABB, 2D (/3D ?) OBB etc...).
• Event
• Utils
• Video
• Network: contains classes to create TCP/IP clients and servers (Linux for instant).

#Compilation

##Linux

###With Apt-Get

• sudo apt-get install glew-utils libsdl2-dev libsdl2-image-dev libfreetype*
• cd ngengine && git submodule init && git submodule update
• cd build/linux && make

make clean and make mrproper are available in the build/linux makefile.

If you don't succeed to compile, read .travis.yml it details how to install the dependencies.

#Conventions

• Each namespace is in lower case letters.
• 2D and 3D folders are respectively written D2 and D3 because 2D and 3D can't refer to namespaces (namespaces must begin with a letter).
• Each Class or Struct or Enum begins with an upper case letter.

#Warnings

• Lots of comments are in French, others are in English: I'm rewriting them in English.
• The 06_CameraQuat presents a bug: the rotation should be around the left_axis and the normal_axis, and when you do rounds with the camera, it turns over the target_axis too... TO FIX
