engine

Engine is a work in progress entity-component-system based 3D game engine.

Some highlights:

• Physics support
• Deferred rendering used to optimize for many light sources
• Support for loading .obj models

Sample

// We are going to use render, physics and input systems
attach(new RenderSystem("monkey"));
attach(new PhysicsSystem());
attach(new InputSystem());

// Set up the controllable player
Entity *player = new Entity();
player->attach(new Transform(0.0, 2.0, 0.0));
player->attach(new PhysicsCharacter());
player->attach(new InputController());
player->attach(new Camera(CAMERA_DEFAULT));
attach(player);

// Set up a point light
Entity *light = new Entity();
light->attach(new Transform(1.0, 2.0, 0.0));
light->attach(new Light(LIGHT_POINT, Color(255, 255, 255)));
attach(light);

// Set up a monkey
Entity *monkey = new Entity();
monkey->attach(new Transform(2.0, 1.0, 0.0));
monkey->attach(MeshLoader::load("monkey.obj", Color(200, 150, 50)));
monkey->attach(new Physics(PHYSICS_DYNAMIC));
monkey->attach(new Renderer());
attach(monkey);

// Set up the ground
Entity *ground = new Entity();
ground->attach(new Transform(0.0, 0.0, 0.0));
ground->attach(ShapeGenerator::plane(Color(200, 50, 50), 50.0, 50.0));
ground->attach(new Physics(PHYSICS_STATIC));
ground->attach(new Renderer());
attach(ground);

The sample code above produces the following scene:

Build

The following libraries are required to build:

• Bullet
• GLFW 2.7.x
• OpenGL Extension Wrangler Library (GLEW)
• OpenGL Mathematics (GLM)

To build the library along with the samples, just run make.
