Increase velocity -increase distance

Unity Engine
1

I don’t know how to implement relationship of velocity and distance correctly. I have generator of platforms, when a player(ball) get to the end of platforms, player jump to the next. At the same time generator create a new platform. Velocity of player , straightforce (for jump) and distance between platforms are constant. But i want to increase velocity after 5 covered platforms and i dont relationship between increasing velocity and distance between platform.

//Spawnscript
private float offset = 20.8277f;
     private float zpos = 104.1335f;
     void OnTriggerEnter(Collider other)
  if (kk != 6)
        {
            if (other.tag == "jump")
            {

                zpos +=  set;
if ((kk % 9) != 0)
                {
                    plt[(kk % 10)] = Instantiate(obj, Vector3.forward * zpos, Quaternion.identity);
}

  else
                {
                    plt[(kk % 10)] = Instantiate(obj10, Vector3.forward * zpos, Quaternion.identity) as GameObject;
                    }

//Script for movement:
     private float straightforce = 3f
   
    private float force = 3000f
    private float gravity = 6.8f, gravitymax = 15f;

    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }
 

    void FixedUpdate()
    {
        rb.velocity = new Vector3(0, 0, straightforce);



    }
    void Update()
    {


    }



    void OnTriggerEnter(Collider other)
    {


        if (other.tag == "jump")
        {



            rb.AddForce(0, force, 0);
        }
     

    }
}

Create a “distance ratio” using the starting player speed and the offset value you have.

private const float distanceRatio = offset / startingPlayerVelocity; // 20.8277f / 3f in your current code

// change this:
zpos += offset;
// to this:
zpos += distanceRatio * playerVelocity; // you're going to have to access that value from the other script or some global speed script

So at first, your zpos will increase by the same amount:
zpos = 20.8277
zpos = 41.6554
zpos = 62.4831

but then if you increase the velocity to 5, the gap between platforms will increase too:
zpos = 97.195933333333333333333333333333
zpos = 131.90876666666666666666666666667
zpos = 166.6216

etc. etc.
