Problem with a script

Gamer To Game Developer course.

Hi guys i have a odd problem that i can't see to fix when watching the course.

Member modifier public must precede the member type and name.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;SetInitialRefences
3.  
4.    public class TriggerExample : MonoBehaviour {
5.  
6.     private WalkTroughWall walkTroughWallScript;
7.    
8.     void Start()
9.     {
10.         SetInitialRefences();
11.     }
12.  
13.  
14.     void OnTriggerEnter(Collider other)
15.     {
16.         //Debug.Log(other.name + " has entered");
17.         walkTroughWallScript.SetLayerNotSolid();
18.     }
19.  
20.     void OnTriggerExit(Collider other)
21.     {
22.         //Debug.Log(other.name + " has exited");
23.         walkTroughWallScript.SetLayerToDefault();
24.     }
25.  
26.     //void OnTriggerStay(Collider other)
27.     //{
28.     //    //Debug.Log(other.name + " is in the trigger");
29.     //}
30.  
31.     void SetInitialRefences()
32.     {
33.         if(GameObject.Find("Wall")!= null)
34.         {
35.             walkTroughWallScript = GameObject.Find("Wall").GetComponent<WalkTroughWall>();
36.         }
37.         else
38.         {
39.             Debug.Log("Object is net setup right.");
40.         }
41.        
42.     }
43. }
44.  

 

using System.Collections;SetInitialRefences

Try delete SetInitialRefences

 

Thank u so much seems like i have a lot to learn when it comes to reading errors
