How to change fall delay of a gameobject by time?

Questions & Answers
1

I want my gameobjects to fall faster as the time goes. Gameobject falling is getting called when the player collides with if.

Here’s my code:

    private Rigidbody rb;
    public float currentFallDelay = 1f;
    float minFallDelay = 0.3f;
    public float accelerationTime = 60;
    private float maxFallDelay;
    private float time;

void Start() 
{
    rb = GetComponent<Rigidbody>();
    minFallDelay = currentFallDelay;
    time = 0;
}

    public void FallDelay()
    {
        rb.isKinematic = true;
        currentFallDelay = Mathf.SmoothStep(minFallDelay, maxFallDelay, time / accelerationTime);
        transform.position += Vector3.down * currentFallDelay * Time.deltaTime;
        time += Time.deltaTime;
    }

    void OnCollisionEnter(Collision col) 
    {
        if(rb.isKinematic && col.collider.CompareTag("Player")) 
        {
            FallDelay();
        }
    }

What am I doing wrong?
All helps are appreciated!

Maybe something like this:

Transform.position += Vector3.down * currentFallDelay * time;

As the value of time increase, the object should fall faster.

currentFallDelay = Mathf.SmoothStep(minFallDelay, maxFallDelay, time / accelerationTime);
transform.position += Vector3.down * currentFallDelay * Time.deltaTime;
time += Time.deltaTime;

The problem is above code block is just executed once, so your object’s position only changes in one frame. The logic that changes object’s position for making it moving need to be executed every frame.
In your case, Coroutine could help.

public IEnumerator FallDelay()
{
         rb.isKinematic = true;
         while (true)
        {
         currentFallDelay = Mathf.SmoothStep(minFallDelay, maxFallDelay, time / accelerationTime);
         transform.position += Vector3.down * currentFallDelay * Time.deltaTime;
         time += Time.deltaTime;
          yield return null;
         }
}    


void OnCollisionEnter(Collision col) 
  {
             if (rb.isKinematic && col.collider.CompareTag("Player")) 
             {
                 StartCoroutine(FallDelay());
             }
   }
