Assets/Scripts/weaponSwitch.cs(39,1): error CS1525: Unexpected symbol `}'

So I am trying to create a simple gun switch script, following a tutorial. I'm starting out with only the glock and AK for now, but I will add more once I get the first 2 done. (I am very new to coding.) Whenever I try anything regarding it, I just create more errors. I am seeking help, if anyone can!
Here is the video:

Here is the script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class weaponSwitch : MonoBehaviour {
6.     public GameObject Glock18;
7.     public GameObject AK47;
8.     public GameObject M4Carbine;
9.     public GameObject L96;
10.     public GameObject Shotgun;
11.  
12.     // Use this for initialization
13.     void Start () {
14.  
15.     }
16.  
17.     // Update is called once per frame
18.     void Update () {
19.         if (Input.GetKeyDown (KeyCode.E)) {
20.             RaycastHit hit;
21.             if (Physics.Raycast (Camera.main.transform.forward, transform.forward, out hit));
22.                 if (hit.transform.tag == "item")
23.                     if(hit.transform.gameObject.name.Contains("World Model Glock-18")){
24.                         if(weaponOut==1){
25.                             changeWeapon(1);
26.                             if (weaponOut == 1) {
27.                                 Destroy (hit.transform.gameObject);
28.                                 Instantiate (Glock18, transform.root.transform.position + new Vector3 (0, 2, 0), Quaternion.identity);
29.                             }else if(weaponOut==2){
30.                                     Destroy(hit.transform.gameObject);
31.                                     Instantiate(AK47, transform.root.transform.position+new Vector3(0, 2, 0), Quaternion.identity);
32.  
33.                             }
34.                         }
35.                     }
36.                 }
37.             }
38.         }
39.     }
40.     void changeWeapon(int weapon){
41.         if (weaponIn == 1) {
42.             weaponOut == 1;
43.             transform.FindChild ("World Model Glock-18").gameObject.SetActive (false);
44.             transform.FindChild ("World Model AK-47").gameObject.SetActive (true);
45.         } else if (weaponIn == 2)
46.             weaponOut == 2;
47.         transform.FindChild ("World Model Glock-18").gameObject.SetActive (true);
48.         transform.FindChild ("World Model AK-47").gameObject.SetActive (false);
49.  
50. }

 

i found one of the problems, you were closing your class on the line 39, so every line from 40 was wrong in the syntax.

this is a fairly easy mistake to catch, seems like you are really new to code.

if i may, i suggest you to practice the basics a little more, before trying something more complex, here some links

I tried to debug your code, even not knowing the context so, it maybe still wrong. here you go:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. public class weaponSwitch : MonoBehaviour {
5.  
6.     public GameObject Glock18;
7.     public GameObject AK47;
8.     public GameObject M4Carbine;
9.     public GameObject L96;
10.     public GameObject Shotgun;
11.     // Use this for initialization
12.     void Start () {
13.     }
14.     // Update is called once per frame
15.     void Update () {
16.  
17.         if (Input.GetKeyDown (KeyCode.E)) {
18.             RaycastHit hit;
19.  
20.             if (Physics.Raycast (Camera.main.transform.forward, transform.forward, out hit)){
21.  
22.                 if (hit.transform.tag == "item"){
23.  
24.                     if(hit.transform.gameObject.name.Contains("World Model Glock-18")){
25.  
26.                         if(weaponOut==1){
27.  
28.                             changeWeapon(1);
29.  
30.                             if (weaponOut == 1) {
31.                                 Destroy (hit.transform.gameObject);
32.                                 Instantiate (Glock18, transform.root.transform.position + new Vector3 (0, 2, 0), Quaternion.identity);
33.                             }else if(weaponOut==2){
34.                                     Destroy(hit.transform.gameObject);
35.                                     Instantiate(AK47, transform.root.transform.position+new Vector3(0, 2, 0), Quaternion.identity);
36.                             }
37.                         }
38.                     }
39.                 }
40.             }
41.         }
42.     }
43.  
44.     void changeWeapon(int weapon){
45.  
46.         if (weaponIn == 1) {
47.             weaponOut == 1;
48.             transform.FindChild ("World Model Glock-18").gameObject.SetActive (false);
49.             transform.FindChild ("World Model AK-47").gameObject.SetActive (true);
50.         } else if (weaponIn == 2){
51.             weaponOut == 2;
52.      
53.         transform.FindChild ("World Model Glock-18").gameObject.SetActive (true);
54.         transform.FindChild ("World Model AK-47").gameObject.SetActive (false);
55.  
56.         }
57.     }
58.  
59. }

Good luck!
