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


a The start value.
b The end value.
t The interpolation value between the two floats.


float The interpolated float result between the two float values.


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 increate 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; } } }
