三.js:按名称或 ID 访问场景对象 [英] three.js: Access Scene Objects by Name or ID

问题描述

我正在从一个我这样定义的数组中生成对象(不限于这三个):

I'm generating objects from an array which I've defined like this (It's not limited to these three):

var links = [['Linkedin','img/linkedin.png','-300','-230', '600'],
             ['Google+', 'img/google.png',  '0',   '-230', '600'],
             ['Twitter', 'img/twitter.png', '300', '-230', '600']];

现在它通过每个循环通过 Three.JS 创建对象并将其添加到场景中，如下所示:

Now it goes through the each loop to create and add the objects to the scene by Three.JS like this:

$.each(links, function(i, item) {
    var thisItemTexture = THREE.ImageUtils.loadTexture(item[1]);
    thisItemGeo = new THREE.CubeGeometry(60, 60, 60,1 ,1 , 1);
    thisItemMat = new THREE.MeshBasicMaterial({map: thisItemTexture });
    thisItem =    new THREE.Mesh(thisItemGeo, thisItemMat);
    scene.add(thisItem);
    thisItem.position.x = item[2];
    thisItem.position.y = item[3];
    thisItem.position.z = item[4];
    thisItem.castShadow = true;
    thisItem.receiveShadow = true;          
});

问题是:
如何访问我在上述每个循环中创建的对象?

The question is:
How can I access the objects that I've made in the each loop above?

推荐答案

您可以这样做:

myObject.name = "objectName";
...
var object = scene.getObjectByName( "objectName" );

或者递归搜索场景图

var object = scene.getObjectByName( "objectName", true );

或者，您可以通过 ID 进行搜索.

Alternatively, you can search by ID.

var object = scene.getObjectById( 4, true );
