    [Header("Variables")]
    public int exampleInteger = 3;
    public float exampleFloat = 3.5f;
    public string exampleString = "I'm a string!";

    // You can have multiple attributes on one line
    // The Space attribute adds a space (in pixels) before the script.
    [Space(10), Header("More Variables with a space!"), Range(-15.5f, 15.5f)]
    public float clampedExampleFloat = 5.5f;

    // The Range attribute specifies a range of values to experiment with. 
    [Range(0, 10)]

    // The Multi-Line attribute specifies a multi-line text field using an integer to specify the amount of rows
    [Multiline(5)]
    public string exampleMultiLineString = "I'm a multi-line text field\n" + "using the MulitlineAttribute!";
