# Variables y funciones

Aprende qué son las variables y funciones en C# y cómo almacenan y procesan datos dentro de tus scripts de Unity.

¿Qué son las Variables y las Funciones y cómo guardan y procesan información por nosotros?

Este tutorial está incluido en el proyecto [_Scripting_ para principiantes. ](https://learn.unity.com/project/scripting-para-principiantes?language=es&publish=true)

Previo: [Scripts como componentes de comportamiento](https://learn.unity.com/tutorial/scripts-como-componentes-de-comportamiento?language=es&publish=true#)

Siguiente: Convenciones y sintaxis

## 1. Variables y funciones

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

public class VariablesAndFunctions : MonoBehaviour
{   
    int myInt = 5;
    
    
    void Start ()
    {
        myInt = MultiplyByTwo(myInt);
        Debug.Log (myInt);
    }
    
    
    int MultiplyByTwo (int number)
    {
        int ret;
        ret = number * 2;
        return ret;
    }
}
```
