three.js: mesh1.position.set 不是函数

three.js: mesh1.position.set is not a function

我已经尝试了所有方法来设置我新创建的 mesh1 网格对象的位置。 mesh1.position 属性 是只读的,mesh1.setPosition 不存在,mesh1.position.set 也不存在。这是我当前的代码:

var plane1 = new THREE.PlaneGeometry(20, 20, 5, 5);
var mesh1 = utils_misc.mesher(plane1, intersection, 0xffffff, "", false, true, false);

mesher 函数的相关部分如下所示:

function mesher ( aGeometry, position, color, name, woodTexture, doubleSided, debug ) {
// ...
material = new THREE.MeshBasicMaterial( { map: texture, side: THREE.DoubleSide } );
mesh = new THREE.Mesh(aGeometry, material);
mesh.position.set = position;
mesh.name = name;
mesh.callback = function() { makeDOMelements.info.innerHTML = name; };
makeScene.scene.add( mesh );
}

我也试过这个:

mesh1.position.set(intersection.x, intersection.y, intersection.z);

帅哥是怎么摆位的?

这行不通:

mesh.position.set = position;

你需要做

mesh.position.copy( position );

但是

mesh1.position.set(intersection.x, intersection.y, intersection.z);

只要 mesh1 的类型是 Object3D

就应该有效
