Physics2D.RaycastAll not detecting colliders (minor problem...?)

Hello, beginner here.

I created a simple 2D raycastall using a tutorial on Youtube, and the raycast is showing up properly, however my if statement, which should return a debug log, is not a returning anything, which leads me to believe that the raycast is not hitting the collider2d. I have 4 images, all in a row, with collider2d's on each of them. There is an empty game object to the left of the images which holds the code and origin of the ray.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Raycast : MonoBehaviour
6. {
7.     string xpos;
8.     string ypos;
9.  
10.     public float maxRayDistance = 15f;
11.  
12.     void Update()
13.     {
14.         Ray ray = new Ray(transform.position, Vector2.right);
15.         RaycastHit[] hits = Physics.RaycastAll(transform.position, Vector2.right);
16.  
17.         Debug.DrawLine(transform.position, Vector2.right * maxRayDistance, Color.red);
18.  
19.         foreach (RaycastHit hit in hits)
20.         {
21.             Debug.Log("Hit " + hit.collider.name);
22.         }
23.     }
24.  
25. }
26.  

Any help would be greatly appreciated!

 

Are these images Image components? Or are you talking about a GameObject with SpriteRenderer? If Images, these are for the Canvas (UI) and that may be the issue.

Another source of the issue is likely that you've got a Physics.RaycastAll call instead of a Physics2D.RaycastAll call.

 

Thanks for your reply. These are GameObjects with SpriteRenderers, I believe. Also I'm unable to change the Raycast to Physics2D without an error, so I figured Physics.RaycastAll would work, just without a z-axis.
