Three.js - 未捕获TypeError:undefined不是函数 [英] Three.js - Uncaught TypeError: undefined is not a function
问题描述
我在使用Three.js时遇到未捕获的TypeError:undefined不是函数
。
我正在创建 THREE.PerspectiveCamera
的行显示错误。
脚本是
I'm getting the Uncaught TypeError: undefined is not a function
while using Three.js.
The error is being shown for the line where I'm creating a THREE.PerspectiveCamera
.
The script is
window.requestAnimFrame = (function(callback){
return window.requestAnimationFrame ||
window.webkitRequestAnimationFrame ||
window.mozRequestAnimationFrame ||
window.oRequestAnimationFrame ||
window.msRequestAnimationFrame ||
function(callback){
window.setTimeout(callback, 1000 / 60);
};
})();
function animate(lastTime, angularSpeed, three){
// update
var date = new Date();
var time = date.getTime();
lastTime = time;
// render
three.renderer.render(three.scene, three.camera);
// request new frame
requestAnimFrame(function(){
animate(lastTime, angularSpeed, three);
});
}
$(window).bind('load',function(){
var angularSpeed = 0.2; // revolutions per second
var lastTime = 0;
$container = $("#container");
var renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
$container.append(renderer.domElement);
// camera - Uncaught Type Error on the below line
var camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 1, 1000);
camera.position.y = -450;
camera.position.z = 400;
camera.rotation.x = 45 * (Math.PI / 180);
// scene
var scene = new THREE.Scene();
var material = new THREE.LineBasicMaterial({
color: 0x0000ff,
});
var geometry = new THREE.Geometry();
for(var i=0;i<100;i++){
geometry.vertices.push(new THREE.Vector3(i-100,i-100,i-100));
geometry.vertices.push(new THREE.Vector3(i+100,i+100,i+100));
var line = new Three.Line(geometry,material);
scene.add(line);
geometry=new THREE.Geometry();
}
// create wrapper object that contains three.js objects
var three = {
renderer: renderer,
camera: camera,
scene: scene,
};
animate(lastTime, angularSpeed, three);
});
这是因为我宣布相机的方式错了吗?
我检查了three.js文档和示例给出的基本相同。
所以我坚持要做什么。
Is this because the way I'm declaring the camera is wrong? I checked the three.js documentation and the example give there is basically the same. So I'm stuck on what to do.
更新:
当我遇到最后一个时,我正在使用Three.js的本地副本错误。我用链接 http://www.html5canvastutorials.com/libraries/Three.js切换了它一>。
现在,PerspectiveCamera错误消失了,但它在Three.js脚本中产生了一个新错误。错误是未捕获TypeError:无法在Three.js脚本的第337行读取未定义
的属性x
谢谢。
推荐答案
本地副本的问题是你使用了未构建的Three.js文件(那将是src / Three .js文件)。你想要的是build / three.js或build / three.min.js。我将其复制到我的项目中,并在脚本标签的src属性中更改了对它的引用,这一切都开始有效。
The problem with the local copy is you used the unbuilt Three.js file (that would be src/Three.js). The one you want is either build/three.js or build/three.min.js. I copied that into my project, and changed the reference to it in the script tag's src attribute, and it all started working.
简而言之:
mrdoob-three.js-2524525(or some other number here)
|
+----build
| |
| +--three.js <-- YES, CORRECT FILE
| +--three.min.js <-- YES
| ...
|
+----src
... |
+--Three.js <-- NO, PREBUILT FILE THAT ONLY CONTAINS CONSTANTS
