Description

Looks at a target whilst keeping another target in view.

C# Script

<csharp>using UnityEngine;

public class SmoothLookFrame : MonoBehaviour {

public Transform lookAtTarget; public Transform frameTarget; public float distance = 10.0f; public float height = 5.0f; public float damping = 2.0f;

private Vector3 direction; private Vector3 wantedPosition;

void FixedUpdate () {

if (!lookAtTarget || !frameTarget) return;

direction = (frameTarget.position - lookAtTarget.position);

wantedPosition = frameTarget.position + (direction.normalized * distance); wantedPosition.y = wantedPosition.y + height;

transform.position = Vector3.Lerp(transform.position, wantedPosition, damping * Time.deltaTime);

transform.LookAt (lookAtTarget);

}

}</csharp>

Javascript

<javascript>var lookAtTarget : Transform; var frameTarget : Transform; var distance : float = 10.0; var height : float = 10.0; var damping : float = 2.0;

private var direction : Vector3; private var wantedPosition : Vector3;

function FixedUpdate () {

if (!lookAtTarget || !frameTarget) return;

direction = (frameTarget.position - lookAtTarget.position);

wantedPosition = frameTarget.position + (direction.normalized * distance); wantedPosition.y = wantedPosition.y + height;

transform.position = Vector3.Lerp(transform.position, wantedPosition, damping * Time.deltaTime);

transform.LookAt (lookAtTarget); }</javascript>
