transformAcrossSpaces

Keep in mind that this is an advanced function that works with coordinate spaces

Parameters

1. vec: a Vector signal representing the position of the object to "follow"

2. vecParentSpace: The parent space in which vec is located

3. targetParentSpace: A TransformSignal representing the "target space", which in the absolute frame of reference

function transformAcrossSpaces(
  vec: VectorSignal,
  vecParentSpace: TransformSignal,
  targetParentSpace: TransformSignal,
): VectorSignal

Example

With the code example below, the two objects will be placed on top of each other no matter what happens in the rest of the scene

Note: sometimes a reload is required after changing the Scene hierarchy

import { transformAcrossSpaces } from './volts';

// define two SceneObjects
let firstObj: SceneObjectBase, secondarySceneObj: SceneObjectBase;

// make both objects be in the same position
// obj2 is placed on top of obj1
secondarySceneObj.transform.position =
  transformAcrossSpaces(
    firstObj.transform.position,
    firstObj.parentWorldTransform,
    secondarySceneObj.parentWorldTransform
  );
