Object following player when left mouse button is down

Hi,i would like to do a 2d game where if you hold down the left mouse button the object would follow the mouse if you move it,but every time i do this the object dissappears: if(Input.getMouseButtonDown(0)) {
transform.position = Input.MousePosition;
}

 

Are you making 3D game or 2D ?

 

I'd like to make a 2d game.

 

This script will do what you want, but my advice go to Unity Learn, and watch all tutorials here, then watch more and more videos on youtube. Because it will be hard to continue without knowledge.

Script (must be attached to follower GameObject in Unity 2D):

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Movement : MonoBehaviour
6. {
7.     public float movementSpeed = 2.0f;
8.  
9.     void Update()
10.     {
11.         // checking if mouse was pressed down, if yes then implement the script
12.         if (Input.GetKey(KeyCode.Mouse0))
13.         {
14.             // getting mouse position in world coordinate system
15.             Vector2 mouseVector2 = Camera.main.ScreenToWorldPoint(Input.mousePosition);
16.             // changing Object position by -Vector2.MoveTowards- function. Control speed by float -movementSpeed-
17.             transform.position = Vector2.MoveTowards(transform.position, mouseVector2, movementSpeed * Time.deltaTime);
18.         }
19.     }
20. }
21.  

 

Thank you!I will watch the videos, i use to watch Brackeys but i can't write my own codes yet.

 

It will help if you get a little familiar with C#. You can do that just by itself or mixed with how you use it in Unity:

1) by itself: http://learncs.org/
2) unity mixed: https://unity3d.com/learn/tutorials/s/scripting

Learning what's there will help you a lot when it comes to reading & writing scripts.
