Frozen is an open-source HTML5 game engine delivering ease-of-use, rapid development through tooling and modularity.
Our goal is to apply techniques used in building modern webapps to game development, such as AMD modules, dependency management, build process, and project scaffolding.
-
Frozen (single file - AMD loader included)
Development and Production -
Frozen Source (individual modules - bring your own loader or use Dojo)
Usevolo add iceddev/frozento add it to your project
or grab the zip: Frozen Source (but don't forget your dependencies) -
Or just use the boilerplate!
Usevolo create your_project iceddev/frozen-dev-boilerplatewhich will scaffold out a new project for you and install all dependencies
Documentation is available at http://frozenjs.com/doc/
Play examples at http://frozenjs.com/examples/
Examples source code can be found at https://github.com/iceddev/frozen/tree/master/examples
Source available on github: https://github.com/iceddev/frozen
We have tested in:
- Chrome 24 & 26-dev
- Firefox 18 & 19
- IE10 (limited sound support)
- Chrome for Android 18 & 24 (limited sound support)
- Firefox for Android 18-19 & 20a2 (There is a bug in Dojo touch event handling that breaks on mobile FF, We are working towards landing a patch)
- PhantomJS 1.8.1
Most modern browsers should support this game engine if they support canvas, but YMMV with sounds
Our Frozen Box2d Editor is available at http://phated.github.com/frozen-editor/
While builds of Frozen may be tiny, we use some libraries and technologies behind the scenes as to not reinvent the wheel.
These technologies include:
- Node.js and npm - used for dependecy mangement for our build process and development workflow
- Grunt - task runner for our development workflow, and allows for a single entry point into development configuration
- Volo - clientside dependency management and project scaffolding tool
- Dojo - used for AMD loader and some utility modules inside the library, Dojo build process is used to build a single JS file
- dcl - used for generating constructors and supplying AOP convenience methods
- Box2d - used for physics calculations in games
- JSDoc - generates documentation for code
- Jasmine - tests all use Jasmine
- AMD - all modules are written with AMD and the single layer includes an AMD module loader
Warning: don't run npm install unless you need raw source, as this will use volo to install dojo, dojo utils, dcl, and Box2D
All development tasks depend on having dependencies installed.
Use npm install to get all the NPM dependencies and start the volo add
grunt dojo to start the dojo build
grunt jsdoc will generate docs
grunt jasmine to run tests in PhantomJS or grunt jasmine-server to run tests in the browser
grunt lint to lint the source
grunt watch to watch the source and specs and run lint and jasmine when a file changes
Breaking Changes
- None! This is a bug fix release
New Features
- None! This is a bug fix release
Non-Breaking Changes
- Scaling issues in IE10 were fixed
- Fixed issue where ResourceManager was hanging when Audio loading errored
- Made collision masking check against null or undefined instead of hasOwnProperty
- Partial Chrome for Android sound support
Deprecations
- Sound plugin will be moved to plugins 0.3.0
- AudioBase will be renamed Sound in 0.3.0
Breaking Changes
- Default Box#gravityY to 9.8 instead of 10
- Auto-scaling on Box (Will cause problems if you are already scaling and don't account for auto-scaling)P
- Remove dojo/_base/declare from single layer - switch to dcl
- Change color to fillStyle and strokeColor to strokeStyle to stay consistent with canvas API
New Features
- Added Joints (Distance, Prismatic, Revolute) - Box gained methods related to Joints
- Added GameCore#setHeight and GameCore#setWidth to set the game's and canvas' height or width
- Entities gained pointInShape function to determine if a point is within shape
- Collision filtering inside Box and properties on Entities
- Added insideCanvas utility and an insideCanvas property flag on mouse or touch events
- HTML5 Audio Support - with plugin that auto-detects which audio type to use
- Default lineWidth on Entities - used inside default draw
- AMD Plugins for loadImage and loadSound
- BoxGame added for easy creation of Box2d games - added preUpdate to GameCore to support this
- Jasmine tests for the library
Non-Breaking Changes
- loadSound and loadImage now accept a String, Array of Strings, or Object of Strings and return the same type
- Dojo/on is used to listen for Image loading - allows for other event listeners to be added without breaking things
- Removed width and height from Box
- Cleaned up InputManager#resize
- Rewrote pointInPolygon module
- Fix some InputManager bugs
- Add more documentation
- Update examples
Deprecations
- Any method that is just a getter or setter that did nothing else - No reason to continue the Java paradigms
- Animation#createFromTile
- ResourceManager#imageCount, ResourceManager#loadedImages, ResourceManager#playSound
- Sprite#drawCurrentFrame
- Entity#hidden
