Quick Start
Start with a tiny working version
Save screens are often treated like support features, but they directly affect how safe the whole game feels. If players cannot tell which save is newest, accidentally overwrite old progress, or cannot recover from a bad branch, trust drops quickly.
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 saveSlotIndex = 1f;
[SerializeField] private float checkpointDistance = 2f;
[SerializeField] private float retryCount = 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 ? "保存地点を記録" : step == 1 ? "リトライを選ぶ" : "復旧警告を出す";
if (statusText != null)
{
statusText.text = $"{label}\nsaveSlotIndex={saveSlotIndex:0.##}\ncheckpointDistance={checkpointDistance:0.##}\nretryCount={retryCount: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 = $"{label}\nsaveSlotIndex={saveSlotIndex:0.##}\ncheckpointDistance={checkpointDistance:0.##}\nretryCount={retryCount:0.##}";
}
Debug.Log($"セーブと復帰導線: {label}");Complete script
csharp
using UnityEngine;
using TMPro;
public class SaveRecoveryTutorial : MonoBehaviour
{
[SerializeField] private TextMeshProUGUI statusText;
[SerializeField] private float saveSlotIndex = 1f;
[SerializeField] private float checkpointDistance = 2f;
[SerializeField] private float retryCount = 3f;
private int step;
public void NextStep()
{
step = (step + 1) % 3;
var label = step == 0 ? "保存地点を記録" : step == 1 ? "リトライを選ぶ" : "復旧警告を出す";
if (statusText != null)
{
statusText.text = $"{label}\nsaveSlotIndex={saveSlotIndex:0.##}\ncheckpointDistance={checkpointDistance:0.##}\nretryCount={retryCount:0.##}";
}
Debug.Log($"セーブと復帰導線: {label}");
}
}Inspector
Connect the UI reference in the Inspector, then use the button to confirm each value changes.
