Use Databox by script

GetData

To use Databox simply make sure to have a reference to a Databox object.

GetData returns a reference of the data in the database. This means that when changing the health value in the example you won't need to put the changed value back to the database as it gets updated automatically.
    using Databox;

    public class Example : MonoBehaviour
    {
        // The reference to your databox object
        public DataboxObject data;

        // return data of type float
        public void GetData()
        {
            FloatType health = data.GetData<FloatType>("TableName", "EntryName", "ValueName");

            // modify value
            health.Value = 10f;

            Debug.Log(health.Value.ToString());
        }
    }

AddData

To add data by script simply call AddData.

    using Databox;

    public class Example : MonoBehaviour
    {
        // The reference to your databox object
        public DataboxObject data;

        public void AddData()
        {
            // create a new float value
            FloatType health = new FloatType();
            // add value
            health.Value = 100f;

            // Add health to our database
            data.AddData("TableName", "EntryName", "ValueName", health);
        }

    }

OnValueChanged

Each data value has a "on value changed" event which gets called if a value has been changed.

using Databox;

public class Example : MonoBehaviour
{
    public DataboxObject data;

    FloatType health;

    public void Start()
    {
        // get data
        health = data.GetData<FloatType>("TableName", "EntryName", "ValueName");

        // register event
        health.OnValueChanged += OnHealthChanged;
    }

    void OnHealthChanged(DataboxType _data)
    {
        // instead of using a global variable you can also convert the data back
        // var _health = _data as FloatType;

        Debug.Log("Health has been changed " + health.Value.ToString());
    }
}
