Quick Start
Start with a tiny working version
Inventories often feel fine while the game is still small. Problems appear later, when healing items, crafting materials, equipment, quest objects, and temporary loot all begin to compete for the same screen space.
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 itemCount = 1f;
[SerializeField] private float stackSize = 2f;
[SerializeField] private float sortMode = 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 ? "アイテム追加" : step == 1 ? "同種をまとめる" : "並び替える";
if (statusText != null)
{
statusText.text = $"{label}\nitemCount={itemCount:0.##}\nstackSize={stackSize:0.##}\nsortMode={sortMode: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 = $"{label}\nitemCount={itemCount:0.##}\nstackSize={stackSize:0.##}\nsortMode={sortMode:0.##}";
}
Debug.Log($"インベントリ整理とスタック: {label}");Complete script
csharp
using UnityEngine;
using TMPro;
public class InventoryStackTutorial : MonoBehaviour
{
[SerializeField] private TextMeshProUGUI statusText;
[SerializeField] private float itemCount = 1f;
[SerializeField] private float stackSize = 2f;
[SerializeField] private float sortMode = 3f;
private int step;
public void NextStep()
{
step = (step + 1) % 3;
var label = step == 0 ? "アイテム追加" : step == 1 ? "同種をまとめる" : "並び替える";
if (statusText != null)
{
statusText.text = $"{label}\nitemCount={itemCount:0.##}\nstackSize={stackSize:0.##}\nsortMode={sortMode:0.##}";
}
Debug.Log($"インベントリ整理とスタック: {label}");
}
}Inspector
Connect the UI reference in the Inspector, then use the button to confirm each value changes.
