如何在一個對象中組合兩個立方體？

Question

我需要管理對象組的位置作爲一個項目。

我：

tankMesh1 = new THREE.Mesh(geometry, material); 
tankMesh2 = new THREE.Mesh(geometry, material); 
scene.add(tankMesh1); 
scene.add(tankMesh2); 

tankMesh2.position = tankMesh2.position + offset * cos (angle) 

我需要：

tankMeshBig = new THREE.Mesh(tankMesh1 , tankMesh2);

Answer 1

您可以使用一個新的THREE.Object3D()：

JS：

var group=new THREE.Object3D(); 

tankMesh1 = new THREE.Mesh(geometry, material); 
group.add(tankMesh1); 

geometry = new THREE.CubeGeometry(3, 2, 5); 
tankMesh2 = new THREE.Mesh(geometry, material); 
tankMesh2.position.y = 3; 
group.add(tankMesh2); 

group.rotation.y = 3.141/3; 

scene.add(group);
