[유니티 개발] Game Programming Pattern(SOLID 패턴)

Manager 스크립트

using UnityEngine;

public class SelectionManager : MonoBehaviour
{
    private IRayProvider _rayProvider;
    private ISelector _selector;
    private ISelectionResponse _selectionResponse;
    
    private Transform _currentSelection;

    private void Awake()
    {
        _rayProvider = GetComponent<IRayProvider>();
        _selector = GetComponent<ISelector>();
        _selectionResponse = GetComponent<ISelectionResponse>();
    }

    private void Update()
    {
        if (_currentSelection != null) 
            _selectionResponse.OnDeselect(_currentSelection);
        
        _selector.Check(_rayProvider.CreateRay());
        _currentSelection = _selector.GetSelection();
        
        if (_currentSelection != null) 
            _selectionResponse.OnSelect(_currentSelection);
    }
}

RayCastBasedTagSelector 스크립트

using UnityEngine;

public interface ISelector
{
    void Check(Ray ray);
    Transform GetSelection();
}

using UnityEngine;

public class RayCastBasedTagSelector : MonoBehaviour, ISelector
{
    [SerializeField] private string selectableTag = "Selectable";
    
    private Transform _selection;

    public void Check(Ray ray)
    {
        _selection = null;

        if (!Physics.Raycast(ray, out var hit)) return;
        
        var selection = hit.transform;
        if (selection.CompareTag(selectableTag))
        {
            _selection = selection;
        }
    }

    public Transform GetSelection()
    {
        return _selection;
    }
}

IselectionResponse 인터페이스와
IselectionResponse 인터페이스를 상속한 구현(Implement)

OutlineSelectionResponse 스크립트

using UnityEngine;

internal interface ISelectionResponse
{
    void OnSelect(Transform selection);
    void OnDeselect(Transform selection);
}

using UnityEngine;

public class OutlineSelectionResponse : MonoBehaviour, ISelectionResponse
{
    public void OnSelect(Transform selection)
    {
        var outline = selection.GetComponent<Outline>();
        if (outline != null)
        {
            outline.OutlineWidth = 10;
        }
    }

    public void OnDeselect(Transform selection)
    {
        var outline = selection.GetComponent<Outline>();
        if (outline != null)
        {
            outline.OutlineWidth = 0;
        }
    }
}

IRayProvider 인터페이스와
IRayProvider 인터페이스를 상속한 구현(Implement)

MouseScreenRayProvider 스크립트

using UnityEngine;

public interface IRayProvider
{
    Ray CreateRay();
}

using UnityEngine;

public class MouseScreenRayProvider : MonoBehaviour, IRayProvider
{
    public Ray CreateRay()
    {
        return Camera.main.ScreenPointToRay(Input.mousePosition);
    }
}
