Question

我有这个方法：

  self.create_from_prototype_1 = function (x, y, z, body_textures, left_leg_textures, right_leg_textures) {
    var body_geo = new THREE.Geometry();
    var left_leg_geo = new THREE.Geometry();
    var right_leg_geo = new THREE.Geometry();

    self.merge_parts(body_geo, self.get_face(x, y, z), 0);
    self.merge_parts(body_geo, self.get_head(x, y, z), 1);
    self.merge_parts(body_geo, self.get_neck(x, y, z), 2);
    self.merge_parts(body_geo, self.get_body_front(x, y, z), 3);
    self.merge_parts(body_geo, self.get_body(x, y, z), 4);
    self.merge_parts(body_geo, self.get_left_arm(x, y, z), 5);
    self.merge_parts(body_geo, self.get_right_arm(x, y, z), 6);
    self.merge_parts(body_geo, self.get_left_forearm(x, y, z), 7);
    self.merge_parts(body_geo, self.get_right_forearm(x, y, z), 8);
    self.merge_parts(body_geo, self.get_left_hand(x, y, z), 9);
    self.merge_parts(body_geo, self.get_right_hand(x, y, z), 10);

    self.merge_parts(left_leg_geo, self.get_left_leg(x, y, z), 0);
    self.merge_parts(left_leg_geo, self.get_left_thigh(x, y, z), 1);
    self.merge_parts(left_leg_geo, self.get_left_foot(x, y, z), 2);

    self.merge_parts(right_leg_geo, self.get_right_leg(x, y, z), 0);
    self.merge_parts(right_leg_geo, self.get_right_thigh(x, y, z), 1);
    self.merge_parts(right_leg_geo, self.get_right_foot(x, y, z), 2);

    var body_materials = [];
    var left_leg_materials = [];
    var right_leg_materials = [];
    var i;

    for (i = 0; i <= 10; i++) {
      body_materials.push(new THREE.MeshBasicMaterial({
        map : body_textures[ i ]
      }));
    }

    for (i = 0; i <= 2; i++) {
      left_leg_materials.push(new THREE.MeshBasicMaterial({
        map : left_leg_textures[ i ]
      }));
    }

    for (i = 0; i <= 2; i++) {
      right_leg_materials.push(new THREE.MeshBasicMaterial({
        map : right_leg_textures[ i ]
      }));
    }

    var body = new THREE.Mesh(body_geo); // no textures yet :/
    body.geometry.computeFaceNormals();
    body.geometry.computeVertexNormals();

    var left_leg = new THREE.Mesh(left_leg_geo); // no textures yet :/
    left_leg.geometry.computeFaceNormals();
    left_leg.geometry.computeVertexNormals();

    var right_leg = new THREE.Mesh(right_leg_geo); // no textures yet :/
    right_leg.geometry.computeFaceNormals();
    right_leg.geometry.computeVertexNormals();

    Game.scene.add(body);
    Game.scene.add(left_leg);
    Game.scene.add(right_leg);

    return {
      body : body, 
      left_leg : left_leg, 
      right_leg : right_leg
    };
  }

它工作正常并正确渲染最终网格但是如果我不添加材料。但是，如果我使用MeshFaceMaterial对象添加我在上面创建的材质数组，如下所示：

var body = new THREE.Mesh(body_geo, new THREE.MeshFaceMaterial(body_materials)); // no textures yet :/
body.geometry.computeFaceNormals();
body.geometry.computeVertexNormals();

var left_leg = new THREE.Mesh(left_leg_geo, new THREE.MeshFaceMaterial(left_leg_materials)); // no textures yet :/
left_leg.geometry.computeFaceNormals();
left_leg.geometry.computeVertexNormals();

var right_leg = new THREE.Mesh(right_leg_geo, new THREE.MeshFaceMaterial(right_leg_materials)); // no textures yet :/
right_leg.geometry.computeFaceNormals();
right_leg.geometry.computeVertexNormals();

控制台抛出＆＃34;无法读取属性＆＃39;属性＆＃39;未定义的。＆＃34;。这是一个错误吗？我在Google搜索并在一整天内检查了我的代码，我找不到与此问题相关的任何解决方案（我甚至尝试直接加载和添加MeshBasicMaterials用于纹理而且都没有工作）..任何帮助.. ？感谢＆＃39;！小号

MeshFaceMaterial未按预期工作
