Scriptable Architecture

What

Scriptable Objects are an immensely powerful yet often underutilized feature of Unity. Learn how to get the most out of this versatile data structure and build more extensible systems and data patterns.

Use

Scriptable Event

Create Scriptable Event

You can create Scriptable Event by 3 option

• Option 1: via menu Create > Sunflower > Scriptable > Event

• Option 2: menu item Sunflower > Scriptable > Create Event

• Option 3: Open tab Scriptable Event in Sunflower Control Panel

• Scriptable Event no parameter

• Scriptable Event has parameter (int, float, string, bool, vector3,...)

Raise Events

You can raise events by code or by the inspector (Enable Debug Field > button Raise Event)

Raise by code

public class Player : MonoBehaviour
{
    public EventNoParam playerAttackEvent;

    public void Attack()
    {
        playerAttackEvent.Raise();
    }
}

Raise by inspector (Enable Debug Field > button Raise Event)

Listener Events

You can listener event by component Event Listener or by code

Listener by component

• Binding
  • UNTIL_DISABLE : the event is subscribed when OnEnable() and unsubscribed when OnDisable()
  • UNTIL_DESTROY : the event is subscribed when Awake() and unsubscribed when OnDestroy()
• Event Response Data
  • Event : Drag scriptable event here
  • Response() : Response() works similarly to a button's OnClick, When the above Event is raised, the functions embedded in Response() will be called

Listener by code

• Use AddListener to subscribe and unsubscribe

 public EventNoParam playerAttackEvent;

    private void OnEnable()
    {
        playerAttackEvent.AddListener(HandleAttack);
    }

    private void OnDisable()
    {
        playerAttackEvent.RemoveListener(HandleAttack);
    }

    void HandleAttack()
    {
        // Attack
    }

• Use OnRaised to subscribe and unsubscribe

public EventNoParam playerAttackEvent;

    private void OnEnable()
    {
        playerAttackEvent.OnRaised += HandleAttack;
    }

    private void OnDisable()
    {
        playerAttackEvent.OnRaised -= HandleAttack;
    }

    void HandleAttack()
    {
        // Attack
    }
