How to make an object move to another object's location in a 2d game?

Question

Hello, I am trying to figure out how to make a game object (like a player) move to another object (like a house or dungeon) that the player clicked on, but only if they clicked on it. Meaning the player can't move around freely. It doesn't really matter how it gets there, so path finding or anything like that doesn't matter.

I'm sorry if this is a stupid thing to ask, or too much to ask of.

(EDIT - Sorry this only answers the object moving towards another part, i should have read the full description and not been lazy reading the title)

Well this should be relatively simple with Vector2.MoveTowards() then make your code look something like this

 using UnityEngine;
 using System.Collections;
 
 public class MoveTowards : MonoBehaviour {
     GameObject HouseOrDungeon;
     GameObject Player;
     float speed;
 
     // Update is called once per frame
     void Update () {
         float step = speed * Time.deltaTime;
         Player.transform.position = Vector2.MoveTowards(Player.transform.position, HouseOrDungeon.transform.position, step);
     }
 }

Check out the documentation (here)

Hope that helps but please remeber (do this before asking)

Not sure how it would work for the clicking on an object part, i guess you could get the click's x and y coordinates and compare them against the surrounding objects on the screens using (screen point to game point)

by using Vector3 to be = to touch position & instead of HouseOrDungeon.transform.position the target will be that Vector3 with taking care of converting click position from pixels to points because clicks & touches defined by pixels where transform defined by points for example if we have 800 pixel screen width then click in the middle will bee 400 then you will send the transform 400 points imagine that so i think now i have to answer

 public float speed;
 void Update(){
     if (Input.GetMouseButton(0)){
        Vector3 target = Camera.main.ScreenToWorldPoint(Input.mousePosition);//converting
         target.z = transform.position.z;
         transform.position = Vector3.MoveTowards(transform.position, target, speed);
     }
 }
