Lets one object follow another object using only a positional offset

LateFollow.cs

using UnityEngine;

// @kurtdekker
// Purpose: follows another Transform, maintaining the same offset from it.
// Useful for a detached health bar that follows a rotating ship (for instance).
public class LateFollow : MonoBehaviour
{
	public Transform TargetToFollow;

	Vector3 Offset;

	void Start ()
	{
		Offset = transform.position - TargetToFollow.position;	
	}

	void LateUpdate ()
	{
		transform.position = TargetToFollow.position + Offset;	
	}
}
