Quick Start
Start with a tiny working version
Photo mode often gets judged by how many settings it offers, but most players decide whether they like it much earlier. What matters first is how quickly they can enter the mode, remove clutter, frame a shot, and understand what will happen after pressing capture.
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 cameraFov = 1f;
[SerializeField] private float focusDistance = 2f;
[SerializeField] private float uiHidden = 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 ? "撮影モードへ入る" : step == 1 ? "カメラを調整" : "UIを隠して保存";
if (statusText != null)
{
statusText.text = $"{label}\ncameraFov={cameraFov:0.##}\nfocusDistance={focusDistance:0.##}\nuiHidden={uiHidden: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 = $"{label}\ncameraFov={cameraFov:0.##}\nfocusDistance={focusDistance:0.##}\nuiHidden={uiHidden:0.##}";
}
Debug.Log($"フォトモードと撮影UI: {label}");Complete script
csharp
using UnityEngine;
using TMPro;
public class PhotoModeTutorial : MonoBehaviour
{
[SerializeField] private TextMeshProUGUI statusText;
[SerializeField] private float cameraFov = 1f;
[SerializeField] private float focusDistance = 2f;
[SerializeField] private float uiHidden = 3f;
private int step;
public void NextStep()
{
step = (step + 1) % 3;
var label = step == 0 ? "撮影モードへ入る" : step == 1 ? "カメラを調整" : "UIを隠して保存";
if (statusText != null)
{
statusText.text = $"{label}\ncameraFov={cameraFov:0.##}\nfocusDistance={focusDistance:0.##}\nuiHidden={uiHidden:0.##}";
}
Debug.Log($"フォトモードと撮影UI: {label}");
}
}Inspector
Connect the UI reference in the Inspector, then use the button to confirm each value changes.
