Hello again!
My script for touching a 2D gameObject does not work! here it is
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class VLCMODE : MonoBehaviour
{
// Update is called once per frame
void Update()
{
if (Input.GetMouseButtonDown(0))
{
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit2D hit;
if (Physics2D.Raycast2D(ray, out hit))
{
//Select Stage
if (hit.transform.name == "vlc")
{
SceneManager.LoadScene("VLCMODE");
}
}
}
}
}
Please tell me what’s wrong with it! Thanks!
Is there a 2D collider attached to the object?
You need to do Physics2D.Raycast, not Raycast2D. 
Ooooh ok thank you! But there is 2 more errors…
2D raycasts work a bit different from 3D ones. Try this:
var cam = Camera.main;
RaycastHit2D hit = Physics2D.Raycast(new Vector2(cam.ScreenToWorldPoint(Input.mousePosition).x, cam.ScreenToWorldPoint(Input.mousePosition).y), Vector2.Zero, 0f);
if (hit.collider.name == "NAME") {
}
ok but where do i put it in the script?
Replace your old code inside of
if (Input.GetMouseButtonDown(0))
{
// put that code here
}
And don’t forget to replace “NAME” with what you need.
ooooooh ok i’ll try it now
The errors are gone but still another error…
In 2D you don’t use a raycast (especially one of zero length with a zero degenerate direction) to detect if a point overlaps a collider, you use Physics2D.OverlapPoint.
When you have errors on something then please take a look at it in the Scripting Reference. Note that everything is case-sensitive.
For instance, Vector2.zero.

@MelvMay Oh… I’ll try
Oh, my bad, I don’t work with 2D that much. 
My script looks like this for the moment
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class VLCMODE : MonoBehaviour
{
// Update is called once per frame
void Update()
{
if (Input.GetMouseButtonDown(0))
{
var cam = Camera.main;
RaycastHit2D hit = Physics2D.OverlapPoint(new Vector2(cam.ScreenToWorldPoint(Input.mousePosition).x, cam.ScreenToWorldPoint(Input.mousePosition).y), Vector2.zero, 0f);
if (hit.collider.name == "vlc")
{
SceneManager.LoadScene("VLCMODE");
}
}
}
}
But there is still an error…
Yes i know… It’s an errorception…
Like Melv said, check the scripting reference.
if (Input.GetMouseButtonDown(0))
{
Vector2 mPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Collider2D hit = Physics2D.OverlapPoint(mPos);
if (hit != null && hit.transform.name == "vlc")
{
SceneManager.LoadScene("VLCMODE");
}
}
