MVPとは

MV(R)Pで、ModelとViewとPresenterをReactiveで、疎結合に連携したパターン

CounterModel.cs

public class CounterModel
{
    public int Counter {
        get => counter;
        set => counter = value;
    }
    int counter = 0;

    public void PlusCounter()
    {
        counter++;
    }
    public void MinusCounter()
    {
        counter--;
    }
}

CounterView.cs

using UnityEngine;
using UnityEngine.UI;

public class CounterView : MonoBehaviour
{
    [SerializeField] public Button minusButton, plusButton;
    [SerializeField] public Text text;

    public void SetValueText(float value)
    {
        text.text = value.ToString();
    }
}

CounterPresenter.cs

using UnityEngine;
using UniRx;

public class CounterPresenter : MonoBehaviour
{
    [SerializeField] private CounterView _counterView;

    void Start()
    {
        CounterModel model = new CounterModel();
        _counterView.SetValueText(model.Counter);

        _counterView.plusButton
            .OnClickAsObservable()
            .Subscribe(_ => {
                model.PlusCounter();
                _counterView.SetValueText(model.Counter);
            })
            .AddTo(this);

        _counterView.minusButton
            .OnClickAsObservable()
            .Subscribe(_ => {
                model.MinusCounter();
                _counterView.SetValueText(model.Counter);
            })
            .AddTo(this);
    }
}
