## BasicBlackboard.cs

```csharp
using CrashKonijn.RabbitBlackboard.Contracts;

namespace CrashKonijn.BlackboardPro.Blackboards.Examples
{
    // This attribute will enable viewing the generated source for the blackboard in the inspector.
    // Only enable this if you can't use Rider or Visual Studio to view the generated source.
    [DebugBlackboard]
    public partial class BasicBlackboard : BlackboardBehaviour
    {
        // This will generate a HealthSignal containing an int value on this same class.
        // Even though you can't see it in this file, it has been added in another 'partial'.
        // The source generators are automatically run by Unity's compilation process!

        // To view the other partial/generated code you can do the following:
        // In Rider: ctrl + click on the classname
        // In Visual Studio: Place your cursor on the classname and press F12. The declarations window should show and you can select the generated partial. The file is <FileName>_<lite|pro>_generated.cs.
        private int health = 100;
    }
}

```

## BasicHealthBehaviour.cs

```csharp
using CrashKonijn.RabbitBlackboard.Contracts;
using UnityEngine;
using BasicBlackboard = CrashKonijn.BlackboardPro.Blackboards.Examples.BasicBlackboard;

namespace CrashKonijn.BlackboardPro.Examples._01_basic
{
    [RequireComponent(typeof(BasicBlackboard))]
    public class BasicHealthBehaviour : MonoBehaviour
    {
        /* Simple hack to show a button in the editor */
        [Header("Removes 10 health.")]
        [Button(nameof(DoDamage))]
        public string doDamageButton;

        /* Simple hack to show a button in the editor */
        [Header("Adds 10 health")]
        [Button(nameof(Heal))]
        public string healButton;

        private BasicBlackboard blackboard;

        public BasicBlackboard Blackboard
        {
            get
            {
                if (this.blackboard == null)
                {
                    this.blackboard = this.GetComponent<BasicBlackboard>();
                }

                return this.blackboard;
            }
        }

        public void DoDamage()
        {
            this.Blackboard.Health -= 10;
        }

        public void Heal()
        {
            this.Blackboard.Health += 10;
        }
    }
}
