Lerp(Vector2, Vector2, float)

Linearly interpolates between vectors 
a
and 
b
by 
t
.
public static Vector2 Lerp(Vector2 a, Vector2 b, float t)

Parameters

a

Vector2
The first vector to interpolate between.

b

Vector2
The second vector to interpolate between.

t

float
The amount to interpolate between.

Returns

Type

Description

Vector2When 
t
is equal to 0, returns 
a
. When 
t
is equal to 1, returns 
b
. When 
t
is equal to 0.5, returns the midpoint of 
a
and 
b
.

Remarks

The parameter 
t
is clamped to the range [0, 1].
When 
t
= 0 returns 
a
.
When 
t
= 1 return 
b
.
When 
t
= 0.5 returns the midpoint of 
a
and 
b
.

Examples

using UnityEngine;public class Example : MonoBehaviour{    public Vector2 destination;    void Update()    {        //Moves the GameObject from it's current position to destination over time        transform.position = Vector2.Lerp(transform.position, destination, Time.deltaTime);    }}
