Question Raycast2D / DrawRay cursor relative position does not update correctly

Hello folks!
I have written this code to visualise a cursor/crosshair around my player that I will need to shoot some very particular projectiles later on.

So I also need a raycast between the cursor and the player position, which I take from the main player script.

However as you can see in the second image, when I debug with Debug.DrawRay (using the same variables as the raycast) and I move the player away from its starting point I notice that DrawRay does not draw all the way to the new relative cursor position anymore.

What am I doing wrong?
Any suggestion on how to solve?

Code (CSharp):

1. public class CursorXhair : MonoBehaviour
2. {
3.     public Player Player;
4.  
5.     // Start is called before the first frame update
6.     void Awake()
7.     {
8.        Cursor.visible = false;    
9.     }
10.     // Update is called once per frame
11.     void Update()
12.     {
13.         Vector2 mouseCursorPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
14.         transform.position = mouseCursorPos;
15.         Debug.DrawRay(Player.transform.position, mouseCursorPos);
16.         RaycastHit2D Player2Mouse = Physics2D.Raycast(Player.transform.position, mouseCursorPos);
17.     }
18. }

 

Hi Melv. I understood what's happening: I have mistaken position for direction... I thought that could be a problem but then I saw it sorta work so I pushed forward, not quite how to solve these things.

This is how I finally solved it:

Code (CSharp):

1.  void Update()
2.     {
3.         Vector2 playerPos = Player.transform.position;
4.         Vector2 mouseCursorPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
5.         Vector2 direction = mouseCursorPos - playerPos;
6.         transform.position = mouseCursorPos;
7.         Debug.DrawRay(playerPos, direction);
8.         RaycastHit2D Player2Mouse = Physics2D.Raycast(playerPos, direction);
9.     }

 

Drawing works, but collision is wrong for the reasons you mention.

I just changed it to Linecast and it works perfectly. I did not use it before when you first mentioned because I did not know it and was afraid to use it, but turns out is very simple!

Thanks again

 

Interesting! Also kind of makes sense when you think about it. I believe Raycast is just more popular because of all the shooty-shooty bang-bang games and tutorials.
