Repository Structure

Crafty repo

These are the important directories:

*/src -- The source code for Crafty */build -- Scripts for building crafty and its documentation */tests -- Unit tests using the qunit framework. (Several are broken, but core and events should work.) */demos -- Small demos of various parts of Crafty's functionality. They can be used to check functionality not covered by the unit tests (such as whether rendering works!)

Building

The build scripts currently depend on php.

• To build crafty, run build-crafty.sh from the build directory. It generates a new crafty.js in the top level directory of the project. crafty.js is generated by concatanting many separate source files together.
• To build the documentation, run build-api.sh. The documentation will be generated in /build/api. Documentation is generated from comments in the source code.

== Testing ==

Just open up the html files to run the tests in a browser. The following tests should pass; others are broken.

• core.html -- tests many parts of Crafty's core functionality
• events.html -- tests several aspects of Crafty's event system

== Source code== To make Crafty more maintainable, it is split into many separate source files. Build scripts concatanate these files into one monolithic files: crafty.js. Comments in the source code are used to generate the documentation.

core.js --Core methods:

• Crafty.c for creating components, Crafty.e for entities
• bind, unbind and similar event handling code
