Three.js — Uncaught TypeError: THREE.OrbitControls is not a constructor

Question

I am trying to add Orbit Controls to my scene without success. The code below keeps giving me an error Uncaught TypeError: THREE.OrbitControls is not a constructor. I have tried different solutions I came across the web but, the error still persists. What am I doing wrong?

Pseudocode

Add Orbit Controls
Be able to use Orbit Controls in the scene

Thank you in advance.

JS

var renderer = new THREE.WebGLRenderer();
renderer.setSize( window.innerWidth, window.innerHeight );
document.body.appendChild( renderer.domElement );

var scene = new THREE.Scene();

// var camera = new THREE.PerspectiveCamera( 75, window.innerWidth/window.innerHeight, 0.1, 1000 );

// var renderer = new THREE.WebGLRenderer();
// renderer.setSize( window.innerWidth, window.innerHeight );
// document.body.appendChild( renderer.domElement );

// CAMERA
var camera = new THREE.PerspectiveCamera(75, 320 / 240, 1, 1000);
camera.position.set(250, 200, 250);
camera.lookAt(0, 0, 0);

// add controls for the camera
var controls = new THREE.OrbitControls(camera);



var geometry = new THREE.PlaneGeometry(100, 50);
var material = new THREE.MeshBasicMaterial( { color: 0xFFFFFF } );
var plane = new THREE.Mesh( geometry, material );
scene.add( plane );

camera.position.z = 200;

var animate = function () {
  requestAnimationFrame( animate );

    controls.update();

  // plane.rotation.x += 0.01;
  // plane.rotation.y += 0.01;

  renderer.render( scene, camera );

};

animate();

It requires 2 arguments var controls = new THREE.OrbitControls(camera, renderer.domElement) — Blindman67

There is an issue in your codepen. When you import OrbitControls via ES6 imports, it's not necessary to use the THREE namespace. So when doing something like this:

import { OrbitControls } from "https://unpkg.com/[email protected]/examples/jsm/controls/OrbitControls.js";

you have to to create OrbitControls like so:

controls = new OrbitControls( camera, renderer.domElement );

If installed via npm, the correct way to import OrbitControls is thus: import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls';
