Spawn sprite on click and makes the sprite follow mouse pointer while still holding the click?

I have this code for now:

Code (CSharp):

1.        
2. if(Input.GetMouseButton(0))
3.         {
4.             RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);
5.  
6.             if(hit.collider)
7.             {
8.                 if(movingObject == null)
9.                 {
10.                     movingObject = hit.collider.gameObject;
11.                     movingObject.gameObject.GetComponent<SpriteRenderer>().enabled = true;
12.                     movingObject.transform.position = Input.mousePosition;
13.                 }
14.             }
15.         }

I use Input.mousePosition inside an Update() which intends to make the sprite always follow the pointer, but it doesn't work?

 

You're halfway there. First confirm using debug.log's or breakpoints that you're definitely hitting a collider and assigning movingObject. Assuming that's correct, I'd say the issue is that you're setting

Code (CSharp):

1. movingObject.transform.position = Input.MousePosition;

The mouse position is a 2D position relative to the screen, and will hold no semblance to the position in the world. Your best bet would be to use the raycast again, and either cast ScreenToWorldPoint again, or to cast onto the floor in the 3D world. Depending on your setup .

 

Care to elaborate more on how to put that into code?
My game is 2D btw

 

Something similar to this. In this example I've smoothed the movement a little.

Code (CSharp):

1.     Vector3 target = Camera.main.ScreenToWorldPoint(Input.mousePosition);
2.     target.z = movingObject.transform.position.z;
3.     movingObject.transform.position = Vector3.MoveTowards(movingObject.transform.position, target, speed * Time.deltaTime);

 

And you've done it with MoveTowards, rather than the common mistake of using Lerp! Kudos.
