问题描述
关于 r58 中的 EventDispatcer 发生了一些变化，我无法向对象添加更多自定义事件.根据 将自定义事件添加到 Object3D 我曾经拥有:
Something changed in regards to the EventDispatcer in r58 and I cannot add any more custom events to Objects. As per Add custom event to Object3D I used to have:
var spinner_obj = new THREE.Object3D();
THREE.EventDispatcher.call( spinner_obj );
spinner_obj.addEventListener('start', function(event) {alert("GOT THE EVENT");});
spinner_obj.dispatchEvent({type:'start'});
但这在 r58 中停止工作并显示错误消息:
but this stopped working in r58 with the error message:
Object [object Object] has no method 'addEventListener'
推荐答案
现在它使用函数的单个实例，而不是在每个对象中复制它.
Now it's using a single instance of the functions instead of duplicating it in every object.
这是我目前找到的最好的方法:https://github.com/mrdoob/three.js/blob/master/examples/js/loaders/OBJLoader.js#L11-L14
This is the best approach I've found so far:https://github.com/mrdoob/three.js/blob/master/examples/js/loaders/OBJLoader.js#L11-L14
我想我会让 Object3D 扩展 EventDispatcher 原型...
I think I'll make Object3D extend EventDispatcher prototype though...
