How to make an object move diagonally indefinitely?

Question

Unity

Hello! I need that when the button is pressed, the object flies diagonally until it hits the enemy (well, that is, infinitely) or rests on the platform. Show how to do this in code

I did it more for myself, because on Habré it’s unlikely that someone will write code for someone else.
You did not mention in which dimension to write it, incl. drank for 2d. The code is working, I checked. Spherecast (This is for 3d), CircleCast (For 2d) is suitable for both cases.

public class Logic : MonoBehaviour
{
    public float Speed;
    [Header("SphereCast options")]
    public float Radius;
    private void Start()
    {
        _originalSpeed = Speed;
    }
    private void OnMouseDown()
    {
        Detector();
        Movement();
    }
    private void OnMouseUp()
    {
        Speed = 0;
    }
    private void Movement()
    {
        transform.Translate(Speed * Time.deltaTime, Speed * Time.deltaTime, 0);
    }
    float _originalSpeed;
    private void Detector()
    {
        if (Physics2D.CircleCast(transform.position, Radius, transform.right))
        {
            Speed = 0;
        }
        else
        {
            Speed = _originalSpeed;
        }
    }
}
