Aug 5, 2015 · The difference comes down to which aspects of the transform are used or not used when performing the transform: TransformPoint: position, rotation, and scale; TransformDirection: rotation only; TransformVector: rotation and scale only; TransformPoint is used, as the name implies to transform a point from local space to global space. Collections; public class ExampleClass : MonoBehaviour { public GameObject someObject; public Vector3 thePosition; void Start() { // Instantiate an object to the right of the current object thePosition = transform. for example:. position = transform. c1. So in this case, the values returned mean different things but you could interchange them if you wanted.
