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

Descripción

Interpolación lineal entre dos vectores.

Interpola entre los vectores a y b por el interpolante t. El parámetro t se sujeta al rango [0, 1]. Esto se utiliza más comúnmente para encontrar un punto de alguna fracción del camino a lo largo de una linea entre dos puntos extremos (por ejemplo. para mover un objeto gradualmente entre esos puntos).

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

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); } }
