Ability Range and Cast Confirmation UI Design Guide

Use range rings, preview lines, and confirmation cues to reduce failed casts and combat confusion.

Quick Start

Start with a tiny working version

Players do not get frustrated only because an ability is weak. They get frustrated when the game lets them believe a cast should work, then silently turns it into a mistake.

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。

TopicPrototypeTutorial.cs
csharp
    [SerializeField] private TextMeshProUGUI statusText;
    [SerializeField] private float currentStep = 1f;
    [SerializeField] private float changedValue = 2f;
    [SerializeField] private float resultScore = 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。

TopicPrototypeTutorial.cs
csharp
    public void NextStep()
    {
        step = (step + 1) % 3;
        var label = step == 0 ? "準備状態" : step == 1 ? "操作中" : "結果表示";
        if (statusText != null)
        {
            statusText.text = $"{label}\ncurrentStep={currentStep:0.##}\nchangedValue={changedValue:0.##}\nresultScore={resultScore: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。

TopicPrototypeTutorial.cs
csharp
        if (statusText != null)
        {
            statusText.text = $"{label}\ncurrentStep={currentStep:0.##}\nchangedValue={changedValue:0.##}\nresultScore={resultScore:0.##}";
        }
        Debug.Log($"Ability Range and Cast Confirmation UI Design Guide: {label}");

Complete script

TopicPrototypeTutorial.cs
csharp
using UnityEngine;
using TMPro;

public class TopicPrototypeTutorial : MonoBehaviour
{
    [SerializeField] private TextMeshProUGUI statusText;
    [SerializeField] private float currentStep = 1f;
    [SerializeField] private float changedValue = 2f;
    [SerializeField] private float resultScore = 3f;

    private int step;

    public void NextStep()
    {
        step = (step + 1) % 3;
        var label = step == 0 ? "準備状態" : step == 1 ? "操作中" : "結果表示";
        if (statusText != null)
        {
            statusText.text = $"{label}\ncurrentStep={currentStep:0.##}\nchangedValue={changedValue:0.##}\nresultScore={resultScore:0.##}";
        }
        Debug.Log($"Ability Range and Cast Confirmation UI Design Guide: {label}");
    }
}

Inspector

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