LERPing a camera between two set Vector3 coordinates.

Questions & Answers
1

I am attempting to LERP a camera between two set Vector3 coordinates, using an onClick event on a GUI button. I have accomplished this task, with one set back. I must continually click the GUI button to move the camera along its path, until I reach the target position. Instead, I want the player to click the associated camera button once and move to the target position. As an asset designer/3D modeler, I am not proficient with coding at all, so forgive my inexperience. Here is my camera movement script, written in C#.

using UnityEngine;
using System.Collections;

public class CameraMovement : MonoBehaviour {

	private Vector3 Target;
	private Vector3 cameraStartPosition;
	private bool isLerping;
	public float Speed;

	public void CameraPosition1()
	{
		isLerping = true;
		cameraStartPosition = transform.position;
		Target = new Vector3(0, 0, 0);
	}
	public void CameraPosition2()
	{
		isLerping = true;
		cameraStartPosition = transform.position;
		Target = new Vector3(24, 0, 0);
	}
	void FixedUpdate()
	{
		if (isLerping) {
			transform.position = Vector3.Lerp (cameraStartPosition, Target, Speed * Time.deltaTime);
		}

	}

Thank you in advance for your assistance.

in Unity - Scripting API: Vector3.Lerp you need to put parameter t as fraction of time spent in movement and total time of movement

transform.position = Vector3.Lerp (cameraStartPosition, Target, timeFromStart/timeToDestination);

it’s usually float between 0 an 1, there 0 returns the “from” Vector3 and 1 returns the “to” Vector3
