Update breaks function

Questions & Answers

void Update()
{
if (Input.GetKeyDown(“w”))
{
Fire();
}
}

void Fire()
{
    rb.MovePosition(rb.position + Vector2.down * speed * Time.deltaTime);
}

I have the following code and every time I press W, the ball moves only down for 1 instead of multiplying with the speed variable. How can I make the object move as defined in the Fire().

I think you need to use +=

void Fire()
{
     rb.position += Vector2.down * speed * Time.deltaTime;
}

Edit: Sorry Use this instead…

 if(Input.GetKey(KeyCode.W))
 {
      rb.position += Vector2.down * speed * Time.deltaTime;
 }

You want to press W once and have the object continue on for forever?

MovePosition is one time kind of thing unless you call it all the time. Since it’s a rigidbody try AddForce instead.
