Three.js SceneUtils 没有 traverseHierarchy!!!它在哪里？

Question

我没有更新我系统中的 three.js 库。今天，我更新了 three.js 文件。但是我遇到了这个错误:“Uncaught TypeError: Object # has no method 'traverseHierarchy'”。

我用它来检测交叉点:在线代码在这里:https://dl.dropbox.com/u/44791710/test/simple2.html

function Intersect(event) {
    event.preventDefault();
    var mousex = (event.clientX / window.innerWidth) * 2 - 1;
    var mousey = -(event.clientY / window.innerHeight) * 2 + 1;
    var vector = new THREE.Vector3(mousex, mousey, 1);

    var toIntersect = [];
    THREE.SceneUtils.traverseHierarchy(scene, function (child) {
        if (child instanceof THREE.Mesh) {
            toIntersect.push(child);
        }
    });
    var projector = new THREE.Projector();
    projector.unprojectVector(vector, camera);
    var ray = new THREE.Raycaster(camera.position,vector.sub(camera.position).normalize());
    var intersects = ray.intersectObjects(toIntersect);
    if (intersects.length > 0) {
        for (var j = 0; j < intersects.length ; j++){
                target = intersects[j].object;
                console.log('Intersects at ' + mouse.x + '/' + mouse.y + ':');
                for(var i = 0, m = intersects.length; i<m; i++){
                     console.log(intersects[i].object.id, intersects[i]);
                }
        }
    }
}

我需要做什么样的改变？谢谢。

您应该将 scene.traverse(scene, function (child) { 替换为 scene.traverse(function (child) {(我无法添加评论，所以我创建了一个答案)。
