How do I fix this problem?

I have a script for my game's characters' movement. Whenever 2 people add in they both control each other! Can someone help me make it so that the 2 players only control their own characters?

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine.InputSystem;
5.  
6. public class PlayerMovement : MonoBehaviour {
7.  
8.     public float maxSpeed = 5f;
9.     public float rotSpeed = 180f;
10.  
11.     float shipBoundaryRadius = 0.5f;
12.  
13.     void Start () {
14.    
15.     }
16.    
17.     void Update () {
18.  
19.         // ROTATE the ship.
20.  
21.         // Grab our rotation quaternion
22.         Quaternion rot = transform.rotation;
23.  
24.         // Grab the Z euler angle
25.         float z = rot.eulerAngles.z;
26.  
27.         // Change the Z angle based on input
28.         z -= Input.GetAxis("Horizontal") * rotSpeed * Time.deltaTime;
29.  
30.         // Recreate the quaternion
31.         rot = Quaternion.Euler( 0, 0, z );
32.  
33.         // Feed the quaternion into our rotation
34.         transform.rotation = rot;
35.  
36.         // MOVE the ship.
37.         Vector3 pos = transform.position;
38.        
39.         Vector3 velocity = new Vector3(0, Input.GetAxis("Vertical") * maxSpeed * Time.deltaTime, 0);
40.  
41.         pos += rot * velocity;
42.  
43.         // RESTRICT the player to the camera's boundaries!
44.  
45.         // First to vertical, because it's simpler
46.         if(pos.y+shipBoundaryRadius > Camera.main.orthographicSize) {
47.             pos.y = Camera.main.orthographicSize - shipBoundaryRadius;
48.         }
49.         if(pos.y-shipBoundaryRadius < -Camera.main.orthographicSize) {
50.             pos.y = -Camera.main.orthographicSize + shipBoundaryRadius;
51.         }
52.  
53.         // Now calculate the orthographic width based on the screen ratio
54.         float screenRatio = (float)Screen.width / (float)Screen.height;
55.         float widthOrtho = Camera.main.orthographicSize * screenRatio;
56.  
57.         // Now do horizontal bounds
58.         if(pos.x+shipBoundaryRadius > widthOrtho) {
59.             pos.x = widthOrtho - shipBoundaryRadius;
60.         }
61.         if(pos.x-shipBoundaryRadius < -widthOrtho) {
62.             pos.x = -widthOrtho + shipBoundaryRadius;
63.         }
64.  
65.         // Finally, update our position!!
66.         transform.position = pos;
67.  
68.     }
69. }
70.

Thank you!

 

I'm trying to do local multiplayer. And I'm using the new Input system.
