MonoBehaviour.FixedUpdate()

Descripción

Esta función se puede llamar cada frame de framerate fijo, si el MonoBehaviour está habilitado.

FixedUpdate should be used instead of Update when dealing with Rigidbody. For example when adding a force to a rigidbody, you have to apply the force every fixed frame inside FixedUpdate instead of every frame inside Update.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public Rigidbody rb;

    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    void FixedUpdate()
    {
        rb.AddForce(10.0f * Vector3.up);
    }
}

In order to get the elapsed time since last call to Update, use Time.deltaTime This function is only called if the Behaviour is enabled. Override this function in order to provide your component's functionality.
