DropTimer

DropTimer 是一款專為 Paper 伺服器設計的掉落物消失時間控制插件。可以用指令設定全伺服器、個別世界的掉落物消失時間，也能透過遊戲內介面替特定物品（支援完整 NBT 比對）設定專屬時間，從幾秒到 99 分 59 秒，或是永不消失。設定變更後會立即套用到地上已存在的掉落物，不需重啟伺服器。

功能特性

• 三層時間設定：
  • 依照「物品規則 ＞ 世界設定 ＞ 全域設定」的順序決定每個掉落物的消失時間。
  • 每一層都可以設為 never（永不消失）。
  • 適用所有掉落來源：玩家丟出、方塊破壞、生物與玩家死亡、爆炸、投擲器、容器破壞、其他插件生成的掉落物等。
• 直覺的時間格式：
  • 支援純秒數（90）或 分:秒（1:30），最長 99:59。
  • 輸入錯誤時（例如 1:75）會清楚提示，不會寫入錯誤設定。
• NBT 物品規則（遊戲內介面）：
  • 在介面中點擊自己背包裡的物品即可新增規則，插件會複製一份作為比對樣本，背包裡的物品不會被拿走。
  • 每條規則可選擇「完整 NBT」（名稱、附魔、Lore、耐久、容器內容都要相同）或「只比種類」。
  • 每條規則可限定套用的世界，並可調整優先順序。
  • 規則以 Paper 原生格式保存，伺服器升級版本後完整 NBT 不會遺失（1.21.11 建立的規則已實測可於 26.x 正常使用）。
• 即時重新計時：
  • 修改任何設定後，已載入區塊中受影響的掉落物會從當下重新計時；未載入區塊的掉落物會在區塊載入時自動套用。
  • 只有套用設定真的改變的掉落物才會重新計時，其他掉落物維持原本進度。
• 超過原版時間也能精準計時：
  • 設定時間超過原版 5 分鐘時，由插件接手倒數多出來的時間，最後再交回原版處理。
  • 倒數進度存在掉落物本身，區塊卸載、伺服器重啟後照樣接續；區塊未載入時不計時（與原版行為一致）。
• 介面安全防護：
  • 介面全部以左鍵操作；右鍵、Shift、數字鍵、副手鍵、拖曳、雙擊、Q 丟棄與創造模式中鍵一律取消，防止物品被取出或複製。
  • 關閉介面（Esc）即取消，不會儲存未確認的修改。
• 相容原版行為：
  • 只調整掉落物年齡，不影響 Paper 對剛生成實體的處理，遠離玩家的農場掉落物照常合併。
  • 讀取 spigot.yml 的 item-despawn-rate，伺服器自訂的原版消失門檻也能正確計算。
  • 偵測到 Paper alt-item-despawn-rate 開啟時會在主控台提示可能衝突。
• 設定檔保護：
  • 設定檔版本更新時自動補上新設定並保留原有數值與註解，舊檔備份為 config.yml.bak。
  • config.yml 或 items.yml 格式損壞時，會自動備份為 .broken-時間 檔案並以預設值繼續運作，避免資料被覆蓋。
• 版本更新提示：
  • 啟動時與輸入 /dt 時檢查 GitHub 最新版本，僅提示不自動下載。

指令與權限

本插件主指令為 /dt。

droptimer.* 包含以上全部權限。使用任何 /dt 指令都需要 droptimer.use。

時間格式：

• 90：90 秒
• 1:30：1 分 30 秒（最長 99:59）
• never：永不消失

使用範例

1. 調整全伺服器的掉落物消失時間

將所有掉落物改為 2 分鐘後消失：

/dt set 2:00

恢復原版 5 分鐘：

/dt set default

2. 個別世界使用不同時間

地獄掉落物 30 秒消失、終界掉落物永不消失：

/dt world world_nether set 0:30
/dt world world_the_end set never

改回跟隨全域設定：

/dt world world_nether set default

3. 讓特定物品永不消失

1. 手持要保護的物品（例如自訂名稱的武器），執行：

   /dt item add never
   

2. 或執行 /dt item 開啟介面，點擊背包中的物品新增規則，再於規則設定中調整：
   • 消失時間：點擊後在聊天室輸入（輸入「取消」返回介面）。
   • 比對方式：在「完整 NBT」與「只比種類」之間切換。
   • 範圍：選擇規則套用的世界，全部不勾即為所有世界。
   • 優先順序：同一個掉落物同時符合多條規則時，完整 NBT 規則優先，同類型則排越前面越優先。

注意事項

• 僅支援 Paper，不支援 Spigot 與 Folia（在 Spigot 上會顯示提示並自動停用）。
• 永不消失的掉落物會一直留在地上，數量過多時可能造成伺服器卡頓。
• 永不消失、以及超過原版時間正在由插件倒數的掉落物，不會與相同掉落物合併（原版限制），交回原版後即可正常合併。
• 移除插件前，請先執行 /dt set default 並刪除設為 never 的世界設定與物品規則，否則正在由插件倒數的掉落物在移除後會變成永不消失。

DropTimer

DropTimer is an item despawn timer plugin designed specifically for Paper (Minecraft 1.21.11, 26.1 – 26.3) servers. Set how long dropped items stay on the ground server-wide, per world, or per item through an in-game GUI with full NBT matching — anywhere from a few seconds to 99 minutes 59 seconds, or never. Changes apply instantly to items already on the ground, with no restart required.

Features

• Three-Tier Timer Settings:
  • Each dropped item's lifetime is resolved in the order "Item Rules > World Settings > Global Setting".
  • Every tier can be set to never (items never despawn).
  • Works with every drop source: player drops, block breaking, mob and player deaths, explosions, droppers, broken containers, items spawned by other plugins, and more.
• Intuitive Time Format:
  • Accepts plain seconds (90) or minutes:seconds (1:30), up to 99:59.
  • Invalid input (such as 1:75) is clearly reported and never written to the config.
• NBT Item Rules (In-Game GUI):
  • Click any item in your own inventory to create a rule; the plugin stores a copy as the match template and never takes the original item.
  • Each rule can match by "Full NBT" (name, enchantments, lore, durability, and container contents must all match) or by "Item Type Only".
  • Each rule can be limited to specific worlds and reordered by priority.
  • Rules are stored in Paper's native format, so full NBT survives server version upgrades (rules created on 1.21.11 are verified to work on 26.x).
• Instant Re-Timing:
  • After any setting changes, affected items in loaded chunks restart their timer immediately; items in unloaded chunks are updated automatically when their chunk loads.
  • Only items whose applied setting actually changed are re-timed; all others keep their progress.
• Accurate Timing Beyond the Vanilla Limit:
  • When the configured time exceeds vanilla's 5 minutes, the plugin counts down the extra time itself before handing the item back to vanilla.
  • Countdown progress is stored on the item itself and persists across chunk unloads and server restarts; like vanilla, items in unloaded chunks do not count down.
• GUI Protection:
  • All GUIs use left-click only; right-click, Shift-click, number keys, the offhand key, dragging, double-clicking, Q-dropping, and creative middle-click are all cancelled to prevent item removal or duplication.
  • Closing a GUI (Esc) cancels the edit; unconfirmed changes are never saved.
• Vanilla-Friendly Behavior:
  • Only the item's age is adjusted, leaving Paper's handling of newly spawned entities untouched, so drops from farms far away from players still merge normally.
  • Reads item-despawn-rate from spigot.yml, so custom vanilla despawn thresholds are calculated correctly.
  • Warns in the console when Paper's alt-item-despawn-rate is enabled, since it may conflict.
• Config File Protection:
  • When the config version changes, new options are added automatically while existing values and comments are kept; the old file is backed up as config.yml.bak.
  • If config.yml or items.yml becomes malformed, it is automatically backed up as a .broken-<time> file and the plugin keeps running with defaults, so your data is never overwritten.
• Update Notifications:
  • Checks GitHub for the latest release on startup and when running /dt; it only notifies and never downloads automatically.

Commands & Permissions

The primary command for this plugin is /dt.

droptimer.* grants all of the above. Every /dt command requires droptimer.use.

Time Format:

• 90: 90 seconds
• 1:30: 1 minute 30 seconds (up to 99:59)
• never: never despawn

Usage Examples

1. Change the Server-Wide Despawn Time

Make all dropped items despawn after 2 minutes:

/dt set 2:00

Restore vanilla's 5 minutes:

/dt set default

2. Use Different Times per World

Nether drops despawn after 30 seconds, End drops never despawn:

/dt world world_nether set 0:30
/dt world world_the_end set never

Return to the global setting:

/dt world world_nether set default

3. Make a Specific Item Never Despawn

1. Hold the item you want to protect (for example, a custom-named weapon) and run:

   /dt item add never
   

2. Or run /dt item to open the GUI, click an item in your inventory to create a rule, then adjust it in the rule editor:
   • Despawn Time: Click and type the time in chat (type 取消 to return to the GUI; configurable).
   • Match Mode: Toggle between "Full NBT" and "Item Type Only".
   • Worlds: Choose which worlds the rule applies to; leaving all unchecked means every world.
   • Priority: When an item matches multiple rules, Full NBT rules win first; among rules of the same mode, the one listed earlier wins.

Item rules are stored in plugins/DropTimer/items.yml; editing them through the /dt item GUI is recommended.

Notes

• Paper only; Spigot and Folia are not supported (on Spigot the plugin shows a notice and disables itself).
• Items set to never despawn stay on the ground forever and may cause lag in large numbers.
• Items that never despawn, and items currently in the plugin's extended countdown, do not merge with identical items (a vanilla limitation); they merge normally once handed back to vanilla.
• Before removing the plugin, run /dt set default and delete any world settings or item rules set to never; otherwise items in the plugin's extended countdown will never despawn after removal.
