Layermask not working

I have a layermask set to just ignore the Player, the player is in the Player Layer(boy this is a tongue twister)

anyway here is my code

Code (CSharp):

1. RaycastHit2D hit = Physics2D.Raycast(position, Vector2.up,RayLength, ignorePlayer);
2.             {
3.                 Debug.Log("You have hit: " + hit.collider.name);
4.             }

the ignorePlayer is the Layermask

and the Debug is saying hit Player

 

Are you sure you're bot ignoring everything except for player?

 

This is what it looks like this is my first time using layermasks but I think that you are supposed to select the layer you want ignored from the drop down (if not please tell me).

 

Nope, do a:

Code (CSharp):

1. LayerMask ignorePlayer = ~(1 << ignorePlayer);

This will basically invert the layerMask

 

ok so is the 1 mean the first layer or the number of layers that are masked and is << ignorePlayer the Layer name?

 

https://en.wikipedia.org/wiki/Bitwise_operation, the ~ means "invert"

 

thanks but the 1 problem is is that i get this error
error CS0236: A field initializer cannot reference the nonstatic field, method, or property
and if I change it to static the error goes away but the layermask does not work

 

Could you show the function, that does this thing?

 

OK so here is my updated script:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Interaction_base : MonoBehaviour
5. {
6.     public PlayerMovement playermovement;
7.     public float RayLength = Mathf.Sqrt(2);//How far the raycast will go
8.     Rigidbody2D player;
9.  
10.     void Start()
11.     {
12.         player = GetComponent<Rigidbody2D>();
13.     }
14.  
15.     void Update()
16.     {
17.         Debug.DrawLine(player.position, player.position + playermovement.Direction * RayLength, Color.red); // Shows where the raycast is in the inspector
18.  
19.    
20.         if (Input.GetKeyDown("space"))
21.         {
22.             Vector2 position = player.position;
23.             RaycastHit2D hit = Physics2D.Raycast(position, player.position + playermovement.Direction * RayLength,~1 << 9);
24.             {
25.                 Debug.Log("You have hit: " + hit.collider.name);
26.             }
27.         }
28.     }
29. }

EDITED: oh and here are my layers: I want every layer to respond with the collider .name except the player layer also edited script to be ~1<< 9

 

sorry I did not really reply to that Ok here is the error
Assets/Scripts/Interaction_base.cs(12,48): error CS0236: A field initializer cannot reference the nonstatic field, method, or property `Interaction_base.ignorePlayer'

and it is referring to

Code (CSharp):

1.     public LayerMask ignorePlayer = ~(1 << ignorePlayer);

 

Do this:

Code (CSharp):

1. at the variables:
2. public LayerMask ignorePlayer;
3.  
4. in Start:
5. ignorePlayer = ~(1<<ignorePlayer);

You didn't initialize the variable and you're trying to use it

 

Thanks I cant believe I forgot something so basic!
