Get Updated Object Position

Questions
1

Hi,

I need to get the updated object position, currently I am loading an object in a loop and it gets loaded in a L shape structure (increment in x/y axis with each loading), I want to place another object on top of the loaded object, but the other object gets loaded in a straight line rather than being in L shape, is there any function/method I can use to bind them together.

Thanks in advance.

Each object has its own Cartesian space. If you want a child object to be positioned according to a parent object, just add it to the parent object instead of adding it to the scene.

const parentObject = new Object3D();

parentObject.position.set( 0, 1, 0 );

scene.add( parentObject );

const childObject = new Object3D();

parentObject.add( childObject );

// childObject will be positioned at [ 0, 1, 0 ] in scene space ( aka world space )

This seems to be not working in my case, getting this error frequently and positioning is not getting applied same as Parent object, by chance any other example/solution to this problem would be greatful.

three.js:5506 THREE.Object3D.add: object not an instance of THREE.Object3D. undefined

This error means that you are passing something wrong to Object3D.add.
