如何在 Unity 3D 上正确配置触摸？

Question

I'm making a game on Unity3D. The cube, as shown in the attached photo, should move to a certain position, I achieved this, but there was a problem when I click on the screen, it moves several positions at once, I tested this situation with Debug. Log (I also attached the photo), and as you can see, with one click, the function is triggered several times, how to fix it?

PS Also could advise how to add smoothness of movement of the cube, in a certain coordinate, tried through transform.forward, but couldn't figure out how to stop it at the right coordinate.

The cube's position

The Message Debug.Log

private void Update()
{
    CubePosUp_Z = transform.position.z - 0.7f;
    CubePosDown_Z = transform.position.z + 0.7f;
    if (Input.touchCount > 0)
    {
        Touch touch = Input.GetTouch(0);

        if (touch.position.y > Screen.height / 2)
        {
            tempUp = 1;
            tempDown = 0;
        }
        else
        {
            tempUp = 0;
            tempDown = 1;
        }

        if (tempUp == 1 && tempDown == 0)
        {
            UpTran();
        }
        else if (tempUp == 0 && tempDown == 1)
        {
            DownTran();
        }
    }
}

void UpTran()
{
    Debug.Log("Up");

    if (CubePosUp_Z <= -1.4)
    {
        transform.Translate(0, 0, 0, Space.World);
    }
    else if (CubePosUp_Z > -1.4)
    {
        transform.Translate(0, 0, -0.14f, Space.World);
    }
}
void DownTran()
{
    if (CubePosDown_Z >= 1.4)
    {
        transform.Translate(0, 0, 0, Space.World);
    }
    else if (CubePosDown_Z < 1.4)
    {
        transform.Translate(0, 0, 0.14f, Space.World);
    }
}

@TheHotboll Here's your solution:-

[SerializeField] float touchForce = 2f;

void Update ()
{
    if (Input.touchCount > 0)
    {
        Touch touch = Input.GetTouch (0);

        if (touch.phase == TouchPhase.Moved)
        {
            transform.Translate (0f, 0f, touch.deltaPosition.x * touchForce * Time.deltaTime, Space.World);
        }
    }
}

First in the Update () function we check if we are actually swiping or just touching. If we are swiping, then we move the transform using transform.Translate () function on the World Space . You can also add conditions and check for touch.deltaPosition.x . This will work smoothly. Just try it out.
