Библиотека JS dat.gui не работает

0 голосов
/ 28 мая 2018

Я пытался заставить работать библиотеку dat.gui (https://github.com/dataarts/dat.gui)). При запуске моего javascript я вижу следующее сообщение: 

Uncaught TypeError: this.onResize is not a function
    at Object.GUI (GUI.js:429)
    at loadScene (main.js:21)
    at main.js:163

Я не знаком с этой библиотекой итак как я только импортировал его до сих пор, я не знаю, что я, возможно, мог делать неправильно. Я пытался использовать уменьшенную версию, но это возвращает ту же ошибку.

Это код JS, который я использую: 

function update(renderer, scene, camera)
{
//Make the renderer render the scene and the camera
renderer.render(
    scene,
    camera
);

//Calls itself each time the function is called upon using recursion
requestAnimationFrame(function()
{
    update(renderer, scene, camera);
})
}

function loadScene()
{
console.log("LOG: Program start");

//Create dat.gui instance
 var gui = dat.GUI();

//Create scene
var scene = new THREE.Scene();
//Create a fog effect in the scene
//scene.fog = createFog(0xffffff, 0.2);


//Create camera
var camera = new THREE.PerspectiveCamera(
    //Perspective
    45,
    //Ratio
    window.innerWidth/window.innerHeight,
    //Near clipping distance
    1,
    //Far clipping distance
    1000
);

//Set the camera position x,y,z
setCameraPosition(camera, 1, 2, 7);

//Create a box with width, depth and height
var box = createBox(1, 1, 1);
box.position.y = box.geometry.parameters.height/2;

//Create a square plane
var plane = createPlane(4);
plane.name = "plane-1";
rotateObject(plane, -90, 0, 0);

//Create a (point) light source
var pointLight = createLightSource(1, 1, 2, 2, gui);

//Create a sphere
 var sphere = createSphere(0.05);

scene.add(plane);
scene.add(box);
scene.add(pointLight);
pointLight.add(sphere);

//Create renderer
var renderer = new THREE.WebGLRenderer();
//Set renderer size
renderer.setSize(window.innerWidth*0.9, window.innerHeight*0.9);
renderer.setClearColor('gray');
//Get element by ID
document.getElementById('scene').appendChild(renderer.domElement);

//Update the renderer, scene and camera
update(renderer, scene, camera);

return scene;
}

function createFog(color, density)
{
return new THREE.FogExp2(color, density);
}

function createPlane(size)
{
var object = new THREE.PlaneGeometry(size, size);
var material = new THREE.MeshPhongMaterial
({
    color: 'gray',
    side: THREE.DoubleSide
});

var mesh = new THREE.Mesh(object, material);

console.log("LOG: Plane created");
return mesh;
}

function createBox(w, d, h)
{
    var object = new THREE.BoxGeometry(w, d, h);
var material = new THREE.MeshPhongMaterial
({
    color: 'gray'
});

var mesh = new THREE.Mesh(object, material);

console.log("LOG: Box created");
return mesh;
//scene.add(mesh);
}

function createSphere(radius)
{
var object = new THREE.SphereGeometry(radius, 24, 24);
var material = new THREE.MeshBasicMaterial
({
    color: 'white'
});

var mesh = new THREE.Mesh(object, material);

console.log("LOG: Box created");
return mesh;
//scene.add(mesh);
}

function createLightSource(intensity, x, y, z, gui)
{
var light = new THREE.PointLight('white', intensity)
light.position.x = x;
light.position.y = y;
light.position.z = z;

gui.add(light, 'intensity', 0, 10);

return light;
}

function setCameraPosition(camera, x, y, z)
{
//Set camera position
camera.position.x = x;
camera.position.y = y;
camera.position.z = z;

camera.lookAt(new THREE.Vector3(0, 0, 0));

console.log("LOG: Camera position set");
}

function rotateObject(object,degreeX=0, degreeY=0, degreeZ=0)
{
degreeX = (degreeX * Math.PI)/180;
degreeY = (degreeY * Math.PI)/180;
degreeZ = (degreeZ * Math.PI)/180;

object.rotateX(degreeX);
object.rotateY(degreeY);
object.rotateZ(degreeZ);
}

var scene = loadScene();

У меня была такая же проблема.dat.GUI должен быть создан с ключевым словом new .

var gui = dat.GUI(); должно быть var gui = new dat.GUI();

Это решило проблему для меня.
