组件式开发框架 craftyjs

想要少写代码,请用组件式开发吧。传统的oop,一直做着重复的事性.

先理解下概念

Entity            实体        An entity is just an ID

Component    组件       Components are just data

System          系统       Logic that runs on every entity that has a component of the system

 

选择组件

Crafty("2D DOM");    // select all entities with both 2D and DOM Crafty("2D DOM");

Crafty("2D, Canvas") // select entities with either DOM or Canvas Crafty("DOM, Canvas");

Crafty("*")               // select all entities Crafty("*");
