# 클래스

C# 클래스에 데이터를 구조화하고, 클래스의 일부를 초기화하는 생성자를 작성하는 방법을 배웁니다.

클래스를 사용하여 정보를 저장하고 구성하는 방법과, 클래스의 일부와 함께 작동하는 생성자를 생성하는 방법을 알아봅니다.

이 튜토리얼은 [스크립팅의 기초 프로젝트](https://learn.unity.com/project/beginner-gameplay-scripting)에 포함되어 있습니다.

## **SingleCharacterScript**

```csharp
using UnityEngine;
using System.Collections;

        public int bullets;
        public int grenades;
        public int rockets;

            bullets = bul;
            fuel = fu;
        }
        
        // 생성자
        public Stuff ()
        {
            bullets = 1;
            grenades = 1;
            rockets = 1;
        }
    }
    

    // Stuff 클래스의 인스턴스(오브젝트) 생성
    public Stuff myStuff = new Stuff(50, 5, 5);
    
    public Stuff myOtherStuff = new Stuff(50, 1.5f);
    
    void Start()
    {
        Debug.Log(myStuff.bullets); 
    }
}
```

## **MovementControls**

```csharp
using UnityEngine;
using System.Collections;

public class MovementControls : MonoBehaviour

    public float speed;
    public float turnSpeed;
    
    
    void Update ()
    {
        Movement();
    }
    
    
    void Movement ()
    {
        float forwardMovement = Input.GetAxis("Vertical") * speed * Time.deltaTime;
        float turnMovement = Input.GetAxis("Horizontal") * turnSpeed * Time.deltaTime;
        
        transform.Translate(Vector3.forward * forwardMovement);
        transform.Rotate(Vector3.up * turnMovement);
    }

```csharp
using UnityEngine;
using System.Collections;

public class Shooting : MonoBehaviour
{

    {
        if(Input.GetButtonDown("Fire1") && inventory.myStuff.bullets > 0)
        {
            Rigidbody bulletInstance = Instantiate(bulletPrefab, firePosition.position, firePosition.rotation) as Rigidbody;
            bulletInstance.AddForce(firePosition.forward * bulletSpeed);
            inventory.myStuff.bullets--;
        }
