Quick Start
Start with a tiny working version
Backup is not something to postpone until your project gets serious. In beginner game development, the safest baseline is a three-layer setup: local working files, cloud duplication, and version history.
Build it in small code pieces
1. 値を用意する
Inspectorで変更できる値と表示先を置きます。
csharp
[SerializeField] private TextMeshProUGUI statusText;
[SerializeField] private float backupCount = 1f;
[SerializeField] private float lastSaveMinutes = 2f;
[SerializeField] private float restorePointIndex = 3f;2. 状態を変える
ボタンを押した時に、1つだけ状態を進めます。
csharp
public void NextStep()
{
step = (step + 1) % 3;
var label = step == 0 ? "通常保存" : step == 1 ? "破損を検知" : "復元候補を表示";
if (statusText != null)
{
statusText.text = $"{label}\nbackupCount={backupCount:0.##}\nlastSaveMinutes={lastSaveMinutes:0.##}\nrestorePointIndex={restorePointIndex:0.##}";
}3. 画面に表示する
変わった結果を画面に出して確認します。
csharp
if (statusText != null)
{
statusText.text = $"{label}\nbackupCount={backupCount:0.##}\nlastSaveMinutes={lastSaveMinutes:0.##}\nrestorePointIndex={restorePointIndex:0.##}";
}
Debug.Log($"バックアップと復元確認: {label}");Complete script
csharp
using UnityEngine;
using TMPro;
public class BackupRestoreTutorial : MonoBehaviour
{
[SerializeField] private TextMeshProUGUI statusText;
[SerializeField] private float backupCount = 1f;
[SerializeField] private float lastSaveMinutes = 2f;
[SerializeField] private float restorePointIndex = 3f;
private int step;
public void NextStep()
{
step = (step + 1) % 3;
var label = step == 0 ? "通常保存" : step == 1 ? "破損を検知" : "復元候補を表示";
if (statusText != null)
{
statusText.text = $"{label}\nbackupCount={backupCount:0.##}\nlastSaveMinutes={lastSaveMinutes:0.##}\nrestorePointIndex={restorePointIndex:0.##}";
}
Debug.Log($"バックアップと復元確認: {label}");
}
}Inspector
Connect the UI reference in the Inspector, then use the button to confirm each value changes.
