Close public static float Lerp(float a,
float b,
float t);

## Parameters

a | The start value. |

b | The end value. |

t | The interpolation value between the two floats. |

## Returns

**float**
The interpolated float result between the two float values.

## Description

Linearly interpolates between `a`

and `b`

by `t`

.

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`

.

using UnityEngine;

public class Example : MonoBehaviour
{
// animate the game object from -1 to +1 and back
public float minimum = -1.0F;
public float maximum = 1.0F;

// starting value for the Lerp
static float t = 0.0f;

void Update()
{
// animate the position of the game object...
transform.position = new Vector3(Mathf.Lerp(minimum, maximum, t), 0, 0);

// .. and increase the t interpolater
t += 0.5f * Time.deltaTime;

// now check if the interpolator has reached 1.0
// and swap maximum and minimum so game object moves
// in the opposite direction.
if (t > 1.0f)
{
float temp = maximum;
maximum = minimum;
minimum = temp;
t = 0.0f;
}
}
