逻辑和数据的分离
如果需要,系统可以帮助将逻辑和行为与数据分开。我们让系统处理繁重的工作,组件只担心通过其生命周期方法管理数据:
AFRAME.registerSystem('my-component', {
createComplexObject: function (data) {
// Do calculations and stuff with data.
return new ComplexObject(data);
}
});
AFRAME.registerComponent('my-component', {
init: function () {
this.myObject = null;
},
update: function () {
// Do stuff with `this.data`.
this.myObject = this.system.createComplexObject(this.data);
}
});
