# Vector3.Lerp

Switch to Manual
public static Vector3 Lerp (Vector3 a, Vector3 b, float t);

## Description

Линейная интерполяция между двумя vector'aми .

Interpolates between the vectors `a` and `b` by the interpolant `t`. The parameter `t` is clamped to the range [0, 1]. This is most commonly used to find a point some fraction of the way along a line between two endpoints (e.g. to move an object gradually between those points).

When `t` = 0 returns `a`. When `t` = 1 returns `b`. When `t` = 0.5 returns the point midway between `a` and `b`.

```using UnityEngine;
using System.Collections;public class ExampleClass : MonoBehaviour
{
// Transforms to act as start and end markers for the journey.
public Transform startMarker;
public Transform endMarker;    // Movement speed in units/sec.
public float speed = 1.0F;    // Time when the movement started.
private float startTime;    // Total distance between the markers.
private float journeyLength;    void Start()
{
// Keep a note of the time the movement started.
startTime = Time.time;        // Calculate the journey length.
journeyLength = Vector3.Distance(startMarker.position, endMarker.position);
}    // Follows the target position like with a spring
void Update()
{
// Distance moved = time * speed.
float distCovered = (Time.time - startTime) * speed;        // Fraction of journey completed = current distance divided by total distance.
float fracJourney = distCovered / journeyLength;        // Set our position as a fraction of the distance between the markers.
transform.position = Vector3.Lerp(startMarker.position, endMarker.position, fracJourney);
}
}
