Quick Start
Start with a tiny working version
When a teammate goes down in a co-op game, players do not just need drama. They need to know whether the teammate is still savable, how much time is left, who should move first, and what happens if the rescue fails.
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 reviveSeconds = 1f;
[SerializeField] private float bleedoutSeconds = 2f;
[SerializeField] private float helperDistance = 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 ? "ダウンする" : step == 1 ? "蘇生中" : "復帰する";
if (statusText != null)
{
statusText.text = $"{label}\nreviveSeconds={reviveSeconds:0.##}\nbleedoutSeconds={bleedoutSeconds:0.##}\nhelperDistance={helperDistance: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 = $"{label}\nreviveSeconds={reviveSeconds:0.##}\nbleedoutSeconds={bleedoutSeconds:0.##}\nhelperDistance={helperDistance:0.##}";
}
Debug.Log($"ダウン状態と蘇生導線: {label}");Complete script
csharp
using UnityEngine;
using TMPro;
public class ReviveFlowTutorial : MonoBehaviour
{
[SerializeField] private TextMeshProUGUI statusText;
[SerializeField] private float reviveSeconds = 1f;
[SerializeField] private float bleedoutSeconds = 2f;
[SerializeField] private float helperDistance = 3f;
private int step;
public void NextStep()
{
step = (step + 1) % 3;
var label = step == 0 ? "ダウンする" : step == 1 ? "蘇生中" : "復帰する";
if (statusText != null)
{
statusText.text = $"{label}\nreviveSeconds={reviveSeconds:0.##}\nbleedoutSeconds={bleedoutSeconds:0.##}\nhelperDistance={helperDistance:0.##}";
}
Debug.Log($"ダウン状態と蘇生導線: {label}");
}
}Inspector
Connect the UI reference in the Inspector, then use the button to confirm each value changes.
