Mathf.Lerp

Parameters

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.

// Fades from minimum to maximum in one second

var minimum = 10.0;
var maximum = 20.0;

function Update () {
		transform.position = Vector3(Mathf.Lerp(minimum, maximum, Time.time), 0, 0);
}

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public float minimum = 10.0F;
    public float maximum = 20.0F;
    void Update() {
        transform.position = new Vector3(Mathf.Lerp(minimum, maximum, Time.time), 0, 0);
    }
}
