Question

嗨，我有一个webgl问题并使用requestAnimationFrame，如果我继续调试动画很好但是只要我让脚本自由运行我就会从浏览器中得到一个无响应的脚本错误

这是我的HTML：

<!DOCTYPE html>
<html>
<head>
    <title>Earth to WebGL</title>
    <script type="text/javascript" src="../Rec/three.min.js"></script>
    <script type="text/javascript" src="../Rec/jquery-1.6.4.js"></script>
    <script type="text/javascript" src="../Rec/RequestAnimationFrame.js"></script>
    <script type="text/javascript" src="ex_loop.js"></script>
    <script type="text/javascript" src="Earth.js"></script>
    <script>

    var loopProg = null;
    var renderer = null;
    var scene = null;
    var camera = null;
    var mesh = null;
    var earth = null;

    $(document).ready(
            function() {
                var container = document.getElementById("container");
                renderer = new THREE.WebGLRenderer({ antialias: true } );
                renderer.setSize(container.offsetWidth,container.offsetHeight);
                container.appendChild(renderer.domElement)
                scene = new THREE.Scene();
                camera = new THREE.PerspectiveCamera( 45,
                        container.offsetWidth / container.offsetHeight, 1, 4000 );

                earth = new Earth();
                scene.add(earth.getEarth);
                camera.position.set( 0, 0, 3 );

                loopProg = new loopProgram();
                loopProg.add(function(){earth.update()});
                loopProg.add(function(){renderer.render( scene, camera );});
                loopProg.solarLoop();
            }
    );


</script>

我的地球脚本文件

function Earth()
{


   this.getEarth = init();

function init()
{
    var map = {map:THREE.ImageUtils.loadTexture("images/earth_surface_2048.jpg")};
    var material = new THREE.MeshBasicMaterial(map);
    var geometry = new THREE.SphereGeometry(1,32,32);
    return new THREE.Mesh(geometry, material);
}

this.update = function()
{
    this.getEarth.rotation.x += .01;
}

    return this;
}

和循环代码：

function loopProgram()
{
    this.functionsToRun = new Array();
    this.solarLoop= function()
    {
        jQuery.each(this.functionsToRun, function(index,value)
        {
            value ? value() : null;
        });
        var loopRef = this;
        requestAnimationFrame(loopRef.solarLoop());
    }

    this.add = function(func)
    {
        this.functionsToRun[this.functionsToRun.length] = func;
    }
}

你是递归地调用solarLoop而不是只传递回调函数：

requestAnimationFrame(loopRef.solarLoop());

应该是

requestAnimationFrame(loopRef.solarLoop);

带有requestAnimationFrame的webGL无响应脚本
