I'm trying to create a plugin that will call a helicopter every 30 minutes.
This plugin will have the remaining time until the next call and a force call command.
Do you think this will work?

using Oxide.Core.Plugins;
using UnityEngine;

namespace Oxide.Plugins
{
    [Info("AutoHeliCall", "yourname", "1.0.0")]
    [Description("30分おきに自動でヘリを呼び、残り時間を放送。/helicall で即時召喚可能")]
    public class AutoHeliCall : RustPlugin
    {
        private const float heliInterval = 1800f; // 30分 (秒)
        private const float announceStep = 300f;  // 5分 (秒)

        private float timeRemaining;
        private Timer heliTimer;
        private Timer announceTimer;

        void OnServerInitialized()
        {
            StartHeliCycle();
        }

        private void StartHeliCycle()
        {
            timeRemaining = heliInterval;

            heliTimer?.Destroy();
            announceTimer?.Destroy();

            // 1秒ごとに残り時間をカウント
            heliTimer = timer.Every(1f, () =>
            {
                timeRemaining -= 1f;
                if (timeRemaining <= 0f)
                {
                    CallHeli();
                    StartHeliCycle(); // 次のサイクル開始
                }
            });

            // 5分おきに残り時間を放送
            announceTimer = timer.Every(announceStep, () =>
            {
                if (timeRemaining > 0f)
                    AnnounceTime();
            });
        }

        private void CallHeli()
        {
            // アタックヘリコプターをスポーン
            BaseEntity heli = GameManager.server.CreateEntity("assets/prefabs/npc/patrol helicopter/patrolhelicopter.prefab", Vector3.up * 50f);
            if (heli != null)
            {
                heli.Spawn();
                PrintToChat("<color=#ff0000>[Helicopter]</color> <color=#ffff00>アタックヘリコプターが出現しました！</color>");
            }
        }

        private void AnnounceTime()
        {
            int minutes = Mathf.CeilToInt(timeRemaining / 60f);
            PrintToChat($"<color=#ff0000>[Helicopter]</color> <color=#00ffff>次のヘリコプター出現まで残り</color> <color=#ffff00>{minutes}分</color> <color=#00ffff>です。</color>");
        }

        [ChatCommand("helicall")]
        private void CmdHeliCall(BasePlayer player, string command, string[] args)
        {
            CallHeli();
            player.ChatMessage("<color=#ff0000>[Helicopter]</color> <color=#00ff00>ヘリを即時召喚しました！</color>");

            // タイマーをリセットして30分後に次のヘリ
            StartHeliCycle();
        }
    }
}
