Quick Start

Start with a tiny working version

The longer your world or mission structure gets, the more players want fast travel. But convenience alone is not the goal.

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。

FastTravelTutorial.cs
csharp
    [SerializeField] private TextMeshProUGUI statusText;
    [SerializeField] private float unlockedCount = 1f;
    [SerializeField] private float travelCost = 2f;
    [SerializeField] private float selectedPoint = 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。

FastTravelTutorial.cs
csharp
    public void NextStep()
    {
        step = (step + 1) % 3;
        var label = step == 0 ? "未発見地点" : step == 1 ? "解放演出" : "移動先を選ぶ";
        if (statusText != null)
        {
            statusText.text = $"{label}\nunlockedCount={unlockedCount:0.##}\ntravelCost={travelCost:0.##}\nselectedPoint={selectedPoint: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。

FastTravelTutorial.cs
csharp
        if (statusText != null)
        {
            statusText.text = $"{label}\nunlockedCount={unlockedCount:0.##}\ntravelCost={travelCost:0.##}\nselectedPoint={selectedPoint:0.##}";
        }
        Debug.Log($"ファストトラベル解放: {label}");

Complete script

FastTravelTutorial.cs
csharp
using UnityEngine;
using TMPro;

public class FastTravelTutorial : MonoBehaviour
{
    [SerializeField] private TextMeshProUGUI statusText;
    [SerializeField] private float unlockedCount = 1f;
    [SerializeField] private float travelCost = 2f;
    [SerializeField] private float selectedPoint = 3f;

    private int step;

    public void NextStep()
    {
        step = (step + 1) % 3;
        var label = step == 0 ? "未発見地点" : step == 1 ? "解放演出" : "移動先を選ぶ";
        if (statusText != null)
        {
            statusText.text = $"{label}\nunlockedCount={unlockedCount:0.##}\ntravelCost={travelCost:0.##}\nselectedPoint={selectedPoint:0.##}";
        }
        Debug.Log($"ファストトラベル解放: {label}");
    }
}

Inspector

Connect the UI reference in the Inspector, then use the button to confirm each value changes.
