1 second fall iteration bug

Questions & Answers
1

I have a piece of script that causes an object to fall in ticks of 1 second by one meter. However, something is wrong with it, the object just shoots straight down and I can’t see the logic error, if you guys could point out the issue that would be great!
Here’s the function:

void Fall()
    {
        if (posit != limit)
        {
            float pastSecond = 0;
            float currentSecond = Time.time - pastSecond;
            float nextSecond = 1;
            if (currentSecond >= nextSecond)
            {
                transform.position -= new Vector3(0, 1, 0);
                pastSecond = Time.time;
            }
        }
        else
        {
            return;
        }
    }

try this :

public float time = 1;
	public float distance = 1;

	private float _timer;
	private Vector3 _movement;

	void Awake ()
	{
		_movement = new Vector3 (0, -distance, 0);
		_timer = time;
	}

	void Update()
	{
		_timer -= Time.deltaTime;

		if (_timer <= 0)
		{
			transform.position += _movement;
			_timer = time;
		}
	}
