Orange Engine

Oct 01, 2011

This is a 2D and 3D game engine I made back in highschool when I got my first Android phone (~2010). It is written in 100% Java, uses OpenGL ES 1.x (so no shaders), and is surprisingly functional. It weighs in at around ~30k LOC.

It is essentially the engine that powered my first Android game, SpinShip. I pulled out the core engine features and packaged it as a separate reusable engine after I released the game. Unfortunately, I didn't use any version control back when I began development (I backed up my code to DVDs lol), so there's no development history from that point. I also, predictably, lost the source code for SpinShip :(

This engine was used to create the following apps that were/are published on the Android Market/Play Store, a few random non-Google app stores for Android, and Blackberry AppWorld:

SpinShip, SpinShip Lite, SpinShip HD
Crazy Virtual Dice 3D
Paperflight
Outpost
Pixel^3 3d modeling tool
Spike Roller Live Wallpaper
Pitch Speed

It was also used for a handful of apps I made for clients as a freelancer, and a bunch of incomplete personal projects. Pretty much the only thing that kept development of this engine alive was one giant project in particular that I ended up scrapping as well...

Features*

*That I remember...

2D and 3D graphics
API strongly inspired by the Irrlicht3D engine (it was my favorite at the time!)
Works on pretty much every Android version ever (uses basic opengl-es 1.x features only and no dependencies)
OBJ file format loading
Full 2D scene graph with many different types of renderable 'nodes'
sprite, spritesheet, animation, text, etc
Virtual input system
buttons, joystick, toggle widgets, drag widgets
Basic component-based entity system

Source Code

The full source code is up on Github

Here are a bunch of random screenshots of things I made with this engine.
