How to connect joystick?

Hey, guys.Help please.I can not connect the script to work with a joystick.The character turns and directs the weapon towards the mouse.How to connect to the joystick?

Code (CSharp):

1. public void Shoot()
2.     {
3.  
4.  
5.      
6.         GameObject projectile = (GameObject)Instantiate(Bullet, Shooter.transform.position, Quaternion.identity);    
7.         Vector3 mousePos = Input.mousePosition;
8.         mousePos.z = 0;    
9.         Vector3 objectPos = Camera.main.WorldToScreenPoint (transform.position);
10.         mousePos.x = mousePos.x - objectPos.x;
11.         mousePos.y = mousePos.y - objectPos.y;
12.         mousePos.Normalize();
13.         projectile.GetComponent<Rigidbody2D>().velocity = new Vector2 (shootVelocity * mousePos.x, shootVelocity * mousePos.y + Random.Range (-10.5f, 10.5f));
14.         canShoot = false;
15.    
16.     }
17.  
18.     void Update ()
19.     {
20.      
21.    
22.         Vector3 mousePos = Input.mousePosition;
23.         mousePos.z = 0;
24.      
25.         Vector3 objectPos = Camera.main.WorldToScreenPoint (transform.position);
26.         mousePos.x = mousePos.x - objectPos.x;
27.         mousePos.y = mousePos.y - objectPos.y;
28.         mousePos.Normalize();
29.  
30.         float angle = Mathf.Atan2 (mousePos.y, mousePos.x) * Mathf.Rad2Deg;
31.  
32.         shootVelocity = 90;
33.         ShootCDTime = 0.4f;
34.  
35.         if(angle <= 90f & angle >= -90f )
36.         {
37.             player.gameObject.transform.localScale = new Vector3(1f, 1f, 1f);
38.             this.gameObject.transform.localScale = new Vector3(1f, 1f, 1f);
39.             transform.rotation = Quaternion.Euler (new Vector3 (0, 0, angle));
40.         }
41.         else
42.         {
43.             player.gameObject.transform.localScale = new Vector3(-1f, 1f, 1f);
44.             this.gameObject.transform.localScale = new Vector3(-1f, -1f, 1f);
45.             transform.rotation = Quaternion.Euler (new Vector3 (0, 0, angle));
46. }

 

Use Input.GetAxis("Horizontal") and/or "Vertical" to read joystick input. NOTE: the joystick has to already be successfully connected and recognized by whatever OS you are running.

 

I know that to connect GetAxis ("Horizontal") and/or " Vertical,but I do not understand how to register it in the script.Sorry for my English.

 

Lots of tutorials out there. This is one:

You get a floating point value back, you decide how to scale and act on it and move / control your character.

The primary hurdle you face is that the mouse you are using is positional (immediate here) whereas the joystick is relative motion (go left, go right), but the tutorial shows how to use the relative motion a joystick gives you.

 

Thanks a lot.
