How to move an object to a certain point using rigidbody.velocity?

Question

C++ / C#

I have an object that moves with the help of velocity in X and Y.
When you press the button, it should move to a certain Z coordinate.
Here is the code just moves it along the Z coordinate

rigidbody3D = GetComponent<Rigidbody>();
...
rigidbody3D.velocity = new Vector3(rigidbody3D.velocity.x, rigidbody3D.velocity.y, layerLevelPosition[1].z);

It moves as needed, it needs to hold down the button and at the same time the object moves beyond the desired Z coordinate (layerLevelPosition[1].z).

transform.position = Vector3.MoveTowards(transform.position, new Vector3(transform.position.x, transform.position.y, layerLevelPosition[1].z),0.5f);

This code moves the object to the desired Z coordinate, but you also need to hold down the button.
1) Is it possible to move to a certain Z coordinate using velocity?
2) Is there a method that itself "moves" the object to the desired point or only through a loop?

Answer 1

1.Mathf.Clamp.
2. Loop/coroutines with Vector3.Lerp.
