go-engine

GoEngine

Go engine is a simple game engine intended for 2D or 3D games. This project is currently in progress and it is likely to change significantly over the next year or so.

Features

• OpenGL renderer
• Obj importer
• Lighting Engine
• Particle System
• UI system
• Controller system (mouse, keyboard, joystick)
• Multiplayer networking library

Platform Support

• Windows
• macOS
• webgl/browser (WIP)
• android (Planned)

Instructions

Example programs can be found in examples/*.

Go-Engine uses go-gl which requires opengl. Note: if you are using Xcode 8.3 or above, you will need go1.8.1 or above.

Core Packages

• renderer - package contains common renderer interface and scenegraph implementation.
• opengl - package contains opengl renderer implementation.
• engine - package Is the high level engine interface that handles a lot of boilerplate stuff.
• controller - package Is the api for keyboard/mouse/joystick controllers. (see examples/simple/main.go)
• assets - asset management for images and obj files.

Important Interfaces and Structs

• renderer.Entity (interface) - anything that can be moved, rotated and scaled. (eg. Camera/Node/ParticleEmitter)
• renderer.Spatial (interface) - something that can be Drawn by a Renderer (eg. Geometry/Node)
• renderer.Node (struct) - Container for Spatials.
• renderer.Geometry (struct) - A collection of faces and verticies.
• renderer.Material (struct) - used for texturing a geometry.
• renderer.Camera (struct) - Struct used to manage the camera.
• renderer.Light (struct) - Struct used to manage dynamic lights.
• controller.Controller (interface) - Can have (mouse/keyboard...) events bound to.
• engine.Engine (interface) - The main game engine interface
• engine.Updatable (interface) - anything that can be updated every game simulation step.
