The BananaBread Engine
======================

A port of the Cube 2/Sauerbraten 3D game engine/first person shooter to the
web, compiling C++ and OpenGL to JavaScript and WebGL using Emscripten.

See the **[FAQ](https://github.com/kripken/BananaBread/wiki/FAQ)**.


Demos
-----

A live demo is available here: **[Stable Demo](https://developer.mozilla.org/demos/detail/bananabread)**

There is a non-stable testing version here: http://dl.dropbox.com/u/80664946/index.html

We also have a silly non-game example, http://www.syntensity.com/static/night14/fireworks.html


Overview
--------

Cube 2 is a compact and efficient 3D game engine. By compiling it
to JavaScript and WebGL you can run a complete first person
shooter in your web browser, using only standard web APIs and
without any plugins.

Features:

 * A multitude of visual effects including water reflection/refraction,
   parallax mapping, glare, particle effects,
   lightmaps, skeletal animation (on gpu), etc. etc.
 * Streamlined and quick physics system
  * Ragdoll physics
 * Bot AI with adjustable skill level
 * Integrated in-game editor
 * Fast performance both running on the web or natively
 * zlib license

The original engine also has a lot of other features not yet
enabled (but will be):

 * Multiplayer
  * Multiplayer editing
 * Shadowmapping


Building
--------

Get emscripten and its dependencies,

  http://emscripten.org/

It's recommended to go through the emscripten tutorial to see that it is set
up properly.

You will also need crunch if you want smaller downloads,

  http://code.google.com/p/crunch/

Build in crnlib using the Makefile (if it isn't in the release yet, see the
issue filed on their site where we submitted it,
http://code.google.com/p/crunch/issues/detail?id=1 ). You can disable
crunch if you don't want it, remove all mentions of crunch in
`cube2/src/web/Makefile`.

Then do `make` in `cube2/src/web` for a web build. You can also do `make` in
`cube2/src/native` for a native linux build.

If you have any problems building, feel free to file an issue here or to
find us on emscripten IRC (see emscripten site).

See needed.txt for some possibly useful scripts to package the output.


Running
-------

0. Run
     python -m SimpleHTTPServer 8888
   in cube2/

1. Load localhost:8888 in your browser


Modding
-------

To use maps of your own or make other kinds of changes or additions to the
artwork, see the
**[Modding](https://github.com/kripken/BananaBread/wiki/Modding)**
page.


Debugging
---------

If you append `,debug` to the URL of one of the levels, it will use
`bb.debug.js` instead of `bb.js`. The debug build has not been run
through closure compiler and is much more readable for stack traces
and profiling and so forth.
