Three Arena is an opiniated WebGL game framework to create 3D terrain-based games in an HTML context. It uses three.js 3D engine, machinejs behaviour trees, recastnavigation pathfinding system, knockoutjs dom binding system and other open source projects.

Features

• click-to-move on any .obj mesh object with an easy pathfinding system
• use your level geometry file directly, or load a custom navigation mesh
• single unit control
• mouse & arrow keys camera behaviour
• customizable HTML & CSS for HUD

• game.on('added:character', function)
• character.on('hit', function)
• character.on('death', function)

• You have a super fun idea ? Great !

• add it as a ticket
• you can code it ? send a pull request from master branch !

Not ready (yet)

Examples

Some examples here three-arena.com/examples

Or run npm install && npm start from the project root.

Show me the code

• The main game code is in lib/index.js
• Character class is in lib/character.js
• A spell example is in lib/spell/bite.js

Hack the pathfinding system

The pathfinding is done via an javascript Emscripten-compiled interface above the c++ library recastnavigation. To add methods in this module, you need to code their javascript interface and rebuild the javascript module with

npm run recast

Or build a separated build with

cd recastnavigation/emscripten
./build.sh ../../lib/pathfinding/recast.js
