WebStorm使用FlyControls.js出现问题

我在学习JavaScript的Three.js，可是当我学习到FlyControls.js时，我的代码出现了问题。
代码：
<body>body>
<script src="/three.js">script>
<script src="/controls/FlyControls.js">script>
<script>
    // The "scene" is where stuff in our game will happen:
    var scene = new THREE.Scene();
    var flat = {flatShading: true};
    var light = new THREE.AmbientLight('white', 0.8);
    scene.add(light);

    // The "camera" is what sees the stuff:
    var aspectRatio = window.innerWidth / window.innerHeight;
    var camera = new THREE.PerspectiveCamera(75, aspectRatio, 1, 10000);
    camera.position.z = 500;
    scene.add(camera);

    // The "renderer" draws what the camera sees onto the screen:
    var renderer = new THREE.WebGLRenderer({antialias: true});
    renderer.setSize(window.innerWidth, window.innerHeight);
    document.body.appendChild(renderer.domElement);

    // ******** START CODING ON THE NEXT LINE ********
    function r(max) {
        if (max) {
            return max * Math.random();
        }
        return Math.random();
    }

    function rColor() {
        return new THREE.Color(r(), r(), r());
    }

    function makePlant() {
        var size = 50;
        var x = r(1000) - 500;
        var y = r(1000) - 500;
        var z = r(1000) - 1000;
        var surface = rColor();
        var shape = new THREE.SphereGeometry(size);
        var cover = new THREE.MeshBasicMaterial({color: surface});
        var planet = new THREE.Mesh(shape, cover);
        planet.position.set(x, y, z);
        scene.add(planet);
    }

    for (var i = 0; i < 100; i++) {
        makePlant();
    }
    var contros = new THREE.FlyControls(camera);
    contros.movementSpeed = 100;
    contros.rollSpeed = 0.5;
    contros.dragToLook = true;
    contros.autoForward = false;
    var clock = new THREE.Clock();

    function animate() {
        var delta = clock.getDelta();
        contros.update(delta);
        renderer.render(scene,camera);
        requestAnimationFrame(animate);
    }
    animate();
    // Now, show what the camera sees on the screen:
    renderer.render(scene, camera);
script>
它在3de上是可以正常运行的，但是，它无法在Webstorm中运行。
