Error: Unable to access the 'uuid' property of an undefined value in the Three.js library

I'm a beginner in three.js and I am struggling to understand its meaning.

I am looking to display a .dae object with it.

Can anyone assist me with this issue?

Answer №1

Unrelated, however, it is worth mentioning that the uuid declaration has been updated. The following code snippet has worked well for me:

import { v4 as uuidv4 } from 'uuid';

uuidv4(); // ⇨ '9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcb6d'

I hope this solution proves to be helpful.

Answer №2

This issue is not related to three.js, but rather a JavaScript error that has occurred. The error message indicates

Cannot read property 'uuid' of undefined
, which means that JavaScript is unable to access a property of an undefined variable.

Therefore, the value of your clipObject is currently set to undefined.

I suggest reviewing the following article on JavaScript checking for null vs. undefined and difference between == and === for further clarification.

Answer №3

The mistake occurred in the line below

var action = mixer.clipAction( animations[ 0 ] ).play();

Initially, I referenced code from a sample on the threejs website featuring a dynamic stormtrooper animation from Star Wars. However, in my implementation, I needed the object to remain static. Therefore, I simply deleted that specific line of code.

Answer №4

To resolve the issue, you must disable certain lines as shown below (object doesn't have animation):

const loader = new FBXLoader(); loader.load ( 'files/models/fbx/ContainerBox_05/ContainerBox_05.fbx', function (object) { //mixer = new THREE.AnimationMixer(object); <-- DISABLE THIS

    //const <-- DISABLE THIS
                    
    //action = mixer.clipAction(object.animations[0]); <-- DISABLE THIS
    //action.play(); <-- DISABLE THIS
