How would you Clamp the relative position of an object?(Unity)

Question

How would I clamp the magnitude of a relative position and convert to world coordinates? i.e. (this.pos - other.pos).clampMag(3f).toWorldCoor(); of course this doesn't exist, but how would I do this kind of thing?

Answer 1

Are you familiar with Vector3.ClampMagnitude and Transform.TransformPoint? If not I believe you could simply use:

Vector3 localClamped = Vector3.ClampMagnitude(yourLocalVector, maxLength);
Vector3 worldPos = someTransform.TransformPoint(localClamped);

If you don't have a local transform you are working with, you can take your localClamped Vector3 and add whatever offset Vector3 you are working with.

Vector3 worldPos = localClamped + offset;
