在 Three.js 中更改对象父级? [英] Change Object parent in Three.js?

问题描述

是否可以更改任何对象的父级?

Is it possible to change the parent of any object?

例如:

scene.add(Object);
Object.Add(OtherObject);
OtherObject.parent = scene; // <-- Something like this

我只知道我可以删除对象并在新的父对象中再次创建它，但我希望有另一种方法.我有一些在飞机上的物体，如果我点击它们，我想把它们固定在相机上，这样我就可以一直在相机前看到.如果我再次单击它们，我想再次将父级设置为飞机.

I just know that I can remove the Object and create it again in the new parent, but I'll hope there's another way. I got some Object that are on a plane, if I click them I want fix them to the camera so I can see all the time in front of the camera. And If I click them Again I wanna set the parent again to the plane.

为什么这不起作用?

var obj = clicked.clone();
camera.add(obj);
obj.position.set(0,0,-20);

推荐答案

最简单的方法是使用 THREE.SceneUtils 对象的 detach 和 attach 函数:

Easiest way is to use the detach and attach functions of the THREE.SceneUtils object:

THREE.SceneUtils.detach( child, parent, scene );
THREE.SceneUtils.attach( child, scene, parent );
