babylon.js 如何访问其功能之外的网格 [英] babylon.js how to get access to a mesh outside of it's function

问题描述

我无法访问巴比伦网格.每次我尝试运行代码时，我都会得到这个错误.

I just cant get access to the babylon mesh. Everytime I try to run the code I get this error.

我尝试了两种不同的方法:

I've tried it with two different approaches:

示例 1:

var carTest;
BABYLON.SceneLoader.ImportMesh("", "assets/", "car.obj", scene, function(object) {
        carTest = object[0];
    });
carTest.position.x = 10;

示例 2:

var carTest = BABYLON.SceneLoader.ImportMesh("", "assets/", "car.obj", scene);
carTest.position.x = 10;

推荐答案

如果您知道 async/await 的概念，您可以使用 async 函数代替带有回调函数的同步方法.

Instead of using the synchron method with callback function you could use the async function if you know the concept of async / await.

示例:

const data = await SceneLoader.ImportMeshAsync("", "assets/", "car.obj", scene);
const carMeshes = data.meshes;

如果您知道只有一个有孩子，您可以访问 [0] 否则您可能需要合并网格.取决于你想做什么.

If you know there is only one with children you could access [0] otherwise you may need to merger the meshes. Depends on what you want to do.
