How to make it possible to move up and down?

Question

Unity

While there is such a line that makes the object constantly fly to the left:

public GameObject obj;
  private float speed = 10f;
  void Update()
  {
  	StartCoroutine(moveObj());
  }
  IEnumerator moveObj () {
  	yield return new WaitForSeconds(1f);
  	obj.transform.Translate(Vector2.left * speed * Time.deltaTime);
  }

But how can I make it so that I can control the object even up and down while it flies to the left, while keeping my finger on the screen? I heard that they do it through IDragHandler .
Do not criticize strictly, I'm still learning, I hope for understanding :)

Answer 1

What it is? Maybe I already flew away from new technologies in a day, to make a curutina to constantly pull to the left. I just don't understand why you need a delay of 1 second, but okay
Throw it into an update or curutina
float yPoz = Input.GetAxis("Vertical");
Vector2 direction = new Vector2(-1,yPoz);
obj.transform.Translate(direction * speed * Time.deltaTime);
yPoz calculates up or down, while direction calculates the direction. But, here it will move smoothly up or down, but if you need it sharply by 1 unit, then through the KeyCode you already need it
. At the expense of touches for android, this is another question, but there you just read it in Google and paste the code into the method
