Quick Start
Start with a tiny working version
Shop balance is not mainly about realistic numbers. It is about helping players understand what their next investment should be.
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 coinCount = 1f;
[SerializeField] private float itemPrice = 2f;
[SerializeField] private float upgradeCost = 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 ? "価格を見る" : step == 1 ? "所持金と比べる" : "購入後を更新";
if (statusText != null)
{
statusText.text = $"{label}\ncoinCount={coinCount:0.##}\nitemPrice={itemPrice:0.##}\nupgradeCost={upgradeCost: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 = $"{label}\ncoinCount={coinCount:0.##}\nitemPrice={itemPrice:0.##}\nupgradeCost={upgradeCost:0.##}";
}
Debug.Log($"ショップ価格と強化コスト: {label}");Complete script
csharp
using UnityEngine;
using TMPro;
public class ShopPricingTutorial : MonoBehaviour
{
[SerializeField] private TextMeshProUGUI statusText;
[SerializeField] private float coinCount = 1f;
[SerializeField] private float itemPrice = 2f;
[SerializeField] private float upgradeCost = 3f;
private int step;
public void NextStep()
{
step = (step + 1) % 3;
var label = step == 0 ? "価格を見る" : step == 1 ? "所持金と比べる" : "購入後を更新";
if (statusText != null)
{
statusText.text = $"{label}\ncoinCount={coinCount:0.##}\nitemPrice={itemPrice:0.##}\nupgradeCost={upgradeCost:0.##}";
}
Debug.Log($"ショップ価格と強化コスト: {label}");
}
}Inspector
Connect the UI reference in the Inspector, then use the button to confirm each value changes.
