Usage Example

using OpenMon.MCE.SDK;
using Zenject;

public class SaveLoadUI : MonoBehaviour
{
    [Inject] private ISaveSystem saveSystem;

    [SerializeField] private Button[] saveButtons;
    [SerializeField] private Button[] loadButtons;
    [SerializeField] private Button[] deleteButtons;
    [SerializeField] private Text[] slotLabels;

    private void Start()
    {
        // Update slot labels
        for (int i = 0; i < 3; i++)
        {
            int slot = i; // Capture for closure
            slotLabels[i].text = saveSystem.HasSaveData(i)
                ? $"Slot {i + 1}: Saved"
                : $"Slot {i + 1}: Empty";

            saveButtons[i].onClick.AddListener(() => saveSystem.Save(slot));
            loadButtons[i].onClick.AddListener(() =>
            {
                if (saveSystem.HasSaveData(slot))
                    saveSystem.Load(slot);
            });
            deleteButtons[i].onClick.AddListener(() =>
            {
                saveSystem.DeleteSave(slot);
                slotLabels[slot].text = $"Slot {slot + 1}: Empty";
            });
        }

        // Listen for save events
        saveSystem.OnSaved += (slot) =>
        {
            slotLabels[slot].text = $"Slot {slot + 1}: Saved";
            Debug.Log($"Game saved to slot {slot + 1}");
        };
    }
}
