Hi all.

I am using the below to throw the Boomerang. It works well if you look at the gif.

What I can’t figure out is on this part. The Boomerang flies to the target max Distance. I want it to slow down Just before it start returning and pick up speed back to the player.

Any help would be great. Thanks!

 rb.velocity = transform.up * speed; // Calculate to go slower when close

Or Better stated. Slow down before reaching Max distance

void Update()
    {
        //Makes the boomerang rotate around its pivot
        spriteHolder.transform.Rotate(0f, 0f, rotationSpeed * Time.deltaTime);

        //Checks if the distance between the spawn point and the boomerang is greater than the maximum distance
        //If it is true and IsTrown is true, the boomerang will return to the player
//Get Max Distance from SpawnPoint. If reached return to player
        if (Vector2.Distance(transform.position, spawn) >= MaxDistance && IsThrown)
        {
            CanReturn = true;
        }

        if (CanReturn)
        {
            GoBack();
        }
    }

public void Throw(Transform spawnPoint) //called from player when Spawning Boom
    {
        if (!IsThrown)
        {
            //Makes the boomerang move
            rb.velocity = transform.up * speed; // Calculate to go slower when close

            //Contains the spawn point
            spawn = spawnPoint.position;

            IsThrown = true;
        }
        else
        {
            return;
        }
    }
    void GoBack()
    {
        CanReturn = true;

        //Calculates the direction so it can return to the player
        Vector2 playerPos = player.position - transform.position;
        rb.velocity = playerPos.normalized * speed;

        //Checks if the distances between player and the boomerang is less than the GrabDistance
        //If it is true it will be destroy the boomerang

        if (Vector2.Distance(transform.position, player.position) < GrabDistance)
        {
            //Allows the player to throw another boomerang
           // GameObject.FindGameObjectWithTag("Player").GetComponent<AttachToPlayer>().CanThrowBoomerang = true;
            GameObject.FindGameObjectWithTag("Player").GetComponent<Aiming>().CanThrowBoomerang = true;
            Destroy(gameObject);
        }
    }

You could use an AnimationCurve object to define an ease-in-ease-out feel to the motion as it nears its limit of flight.

This obviously would require you to confidently predict what the final point of flight is, which might be troubling if a moving target gets in the way of the flying object.

Hmm. Not Ideal like you say. But an Staring point.
