        transform.position = v3OrgPos + (transform.forward) * (transform.localScale.z / 2.0f + orgScale / 2.0f);
        /*if (Input.GetKeyDown(KeyCode.S))

If I use the S and R keys when I press S, the scaling starts smoothly.
However, if you don't use the buttons and start scaling while running the game, there will be some delay, or it looks like the first frame is scaling it by one like a jump effect. Then the scaling continues smoothly.

But the first image, or the first time it looks like it is scaled once and then continued smoothly, does not scale smoothly when the game is run from the beginning.
