Question

我正在编写一个代码来创建一个平面并通过three.js将对象放在其上以下是我的代码。当我尝试运行它时，获取

未捕获的ReferenceError：未定义mythree

为最后一行。

未捕获的SyntaxError：意外的令牌）js / myassn3.js：60

以下是JS代码：

(function (mythree , $, undefined) {
    mythree.init = function (hook) {
        var checkerBoard = undefined;
        var WIDTH  = 600,
            HEIGHT = 500;
        var renderer = new THREE.WebGLRenderer();
        renderer.setSize(WIDTH, HEIGHT);
        hook.append(renderer.domElement);

        // CAMERA SETUP
        var VIEW_ANGLE = 65, 
            ASPECT = WIDTH / HEIGHT,
            NEAR = 0.1,  // these elements are needed for cameras to
            FAR = 10000; // partition space correctly
        var camera = new THREE.PerspectiveCamera(
            VIEW_ANGLE,
            ASPECT,
            NEAR,
            FAR);
        camera.position.z = 300;
        var controls = new THREE.TrackballControls(camera);
        controls.target.set(0, 0, 0)

        // SCENE SETUP
        var scene = new THREE.Scene();
        scene.add(camera);

        // PLAIN SETUP & APPLYING TEXTURE TO IT
        var plane = new THREE.Mesh(new THREE.PlaneGeometry(300, 300), material);
        plane.overdraw = true;
        scene.add(plane);

        // TEXTURE SETUP
        var texture =THREE.ImageUtils.loadTexture('./images/chessboard.jpg');
        var material = new THREE.MeshLambertMaterial({
            map: texture
        });

        var loader = new THREE.JSONLoader();
        var pointLight = new THREE.PointLight(0xFFFFFF);
        pointLight.position = new THREE.Vector3(-10, 30, 100);
        scene.add(pointLight);
        for (i = 0; i < 4; i++) {
            var a = -130;
            loader.load("piece.json", function (geometry) {
                mesh = new THREE.Mesh(geometry, new THREE.MeshBasicMaterial({ color: 0x000000 }));
                mesh.scale.set(30, 30, 30);
                mesh.position = new THREE.Vector3(a, -130, 15); 
                mesh.rotation.x += 1.5;
                a = a + 75;
                scene.add(mesh);
            });
        }

        var render = function () {
            renderer.render(scene, camera);
            controls.update();
            requestAnimationFrame(render);
        };
        render();
        window.requestAnimationFrame(renderLoop);
})(window.mythree = window.mythree || {}, jQuery)

有人可以帮忙解决这个问题吗？

首先：请学习缩进代码。请！
如果您的代码是可读的，或者您只是使用IDE（任何为您计算括号，括号和括号的IDE），则无需向我们寻求帮助。

所以，问题是你的mythree.init函数定义块缺少右括号（}）。我不知道你的mythree.init在哪里结束（只是因为你的代码没有缩进而且真的很混乱），所以自己修复它。
