Three.js可拖动的立方体

Question

参加本教程Draggable cubes我尝试移动我的个人几何立方体但不起作用。在下面的代码中，它适用于geometry2但不适用于geometry0，也许在geometry0中有一些不允许移动的设置？

//geometry0 doesn't move
geometry0 = new THREE.Geometry()
geometry0.vertices = [new THREE.Vector3(0.5, -0.5, 0.5), new THREE.Vector3(-0.5, -0.5, 0.5), new     THREE.Vector3(-0.5, -0.5, -0.5), new THREE.Vector3(0.5, -0.5, -0.5), new THREE.Vector3(0.5, 0.5,    0.5), new THREE.Vector3(-0.5, 0.5, 0.5), new THREE.Vector3(-0.5, 0.5, -0.5), new THREE.Vector3(0.5,   0.5, -0.5)]; 
geometry0.faces = [new THREE.Face3(3, 2, 1), new THREE.Face3(3, 1, 0), new THREE.Face3(4, 5, 6),   new THREE.Face3(4, 6, 7), new THREE.Face3(0, 1, 5), new THREE.Face3(0, 5, 4), new THREE.Face3(1, 2,   6), new THREE.Face3(1, 6, 5), new THREE.Face3(2, 3, 7), new THREE.Face3(2, 7, 6), new THREE.Face3(3,  0, 4), new THREE.Face3(3, 4, 7)]; 
geometry0.computeFaceNormals();
geometry0.computeVertexNormals();
var material0 = new THREE.MeshBasicMaterial( { color: 0x39d2dbe7fff39d2, transparent: true,   opacity: 0 });
mesh0 = new THREE.Mesh( geometry0, material0);
egh0 = new THREE.EdgesHelper( mesh0, 0x000 );
egh0.material.linewidth = 2;
scene.add( egh0 );




geometry2 = new THREE.Geometry() // it works
geometry2.vertices = [new THREE.Vector3(0.5, -0.5, 0), new THREE.Vector3(0.5, -0.166667, 0.5),  new THREE.Vector3(0, -0.5, 0.5), new THREE.Vector3(0.5, -0.5, 0.5)]; 
geometry2.faces = [new THREE.Face3(0, 1, 2), new THREE.Face3(0, 3, 1), new THREE.Face3(1, 3, 2),  new THREE.Face3(2, 3, 0)]; 
geometry2.computeFaceNormals();
geometry2.computeVertexNormals();
var material2 = new THREE.MeshBasicMaterial( { color: 0xffff00 });
mesh2 = new THREE.Mesh( geometry2, material2);
scene.add(mesh2);
egh2 = new THREE.EdgesHelper( mesh2, 0x000 );
egh2.material.linewidth = 2;
scene.add( egh2 );







geometryContainer.push(mesh0);
geometryContainer.push(mesh2);

 plane = new THREE.Mesh( new THREE.PlaneGeometry( 2000, 2000, 8, 8 ), new THREE.MeshBasicMaterial( { color: 0xffff00, opacity: 0.25 } ) );
            //plane.visible = false;
            scene.add( plane );
