TransformControls requires a unique identifier.

Description

Can TransformControls and other controls add type='TransformControls' or isTransformControls property? It would be convenient for raycaster and other functions to filter.

Solution

class TransformControls add type='TransformControls' or isTransformControls = true

Alternatives

The default type of TransformControls is Object3D. By overriding and writing the type, you can avoid this.

The default type of TransformControls is Object3D.

In latest versions TransformControls is derived from Controls so the control instance is no 3D object anymore. The usage looks like so now:

const controls = new TransformControls( camera, renderer.domElement );

const gizmo = controls.getHelper();
scene.add( gizmo );

The 3D object you add to the scene graph via controls.getHelper() has a flag called isTransformControlsRoot. Does that solve your issue?

I tried it and it solved my problem, thanks for your answer. ^_^
