Trying to transform position of gameobject unity using C#

Question

I need some help in trying to change the position of an gameobject and its speed. I know to translate the gameObject but I don't know how to increase the speed of how it translates. I'm using the unity game engine by the way.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class lightning : MonoBehaviour
{
    //This is lightning
    private GameObject name;

    // Start is called before the first frame update
    void Start()
    {
       name=GameObject.Find("car");
    }

    // Update is called once per frame
    void Update()
    {
     if (Input.Keydone("r")
       door.transform.Translate(-Vector3.right * Time.deltaTime);
    }
}

Answer 1

One workaround you can use is a black filter(preferably Image) on UI layer that covers the whole screen. You can change filter's opacity accordingly to achieve the feeling of 'dimmed' screen.

Answer 2

It sounds like you are having trouble with speed and acceleration.
I added a velocity variable and an acceleration variable with the two you can make objects go faster and faster with time.

Since this is Physics I'd recommend you to use a rigidbody on your gameobject and manipulate its speed or to apply a force (force = mass * acceleration) so by adding a force it will give the object an acceleration.

//This is lightning
private GameObject name;
private float speedFactor = 20;
private float accelearationFactor = 5;

// Start is called before the first frame update
void Start()
{
   name=GameObject.Find("car");
}

// Update is called once per frame
void Update()
{
 if (Input.Keydone("r") {
   door.transform.Translate(-Vector3.right * speedFactor * Time.deltaTime);
   speedFactor += accelearationFactor * Time.deltaTime;
 }
}
