TerrainTools
A terraforming toolkit for Paper/Spigot 1.26.x — 3 modules in one jar.
TerrainTools merges the former BedrockReplacer, Seitiassist and CaveEraser plugins. Each module can be toggled in config.yml; commands, permissions and configs are fully compatible with the original plugins.
bedrock module — bedrock replacement
Replaces BEDROCK with DEEPSLATE chunk by chunk (/br chunk, /br radius <1-20>), keeping the bottom layer intact. Perfect for clearing the nether ceiling. Progress reporting and cancellation included.
seiti module — area clearing tools (item-based)
Give players tools instead of commands:
- Clearing wand — select two corners, sneak-right-click to clear the region (costs 1 diamond per 64 blocks)
- Area pickaxe — mine 1×1 up to 7×7 per swing (sneak for normal mining)
- Mega pickaxe — event-reward tier, 9×9 up to 21×21
- Fluid solidifier — hold the trigger item in your offhand: LAVA→OBSIDIAN, WATER→COBBLESTONE around your mining (costs XP)
- Smart trash — filter GUI; filtered items vanish on pickup and grant XP. Players open it via a
[ゴミ箱]sign.
cave module — underwater cave filling
Detects water-flooded natural caves via BFS scan and fills them with allowed blocks. chunkfill mode skips detection and bulk-fills WATER/LAVA/AIR per chunk for rough terraforming. Optional emerald cost via CasinoPlugin (free when not installed).
Design
- Commands are OP-only by default; regular players use the distributed tools and signs.
- One failed module never affects the others.
Setup
Drop the jar in plugins/, restart. Toggle modules in config.yml; per-module settings in modules/seiti.yml / modules/cave.yml.
日本語
旧 BedrockReplacer / Seitiassist / CaveEraser を統合した整地プラグインです。
- bedrock: 最下層を除く岩盤をディープスレートに置換（チャンク単位／半径指定、進捗表示・中断可）。ネザー天井の整地に。
- seiti: 範囲削除の杖（64ブロックにつきダイヤ1消費）、範囲採掘ツルハシ（1×1〜7×7）、メガツルハシ（9×9〜21×21）、オフハンド発動の流体凝固（溶岩→黒曜石、水→丸石）、拾った瞬間に消去して経験値化するスマートゴミ箱（看板でGUIを開放）。
- cave: 水中洞窟をBFS検出して埋立。チャンク一括の粗整地モードあり。CasinoPlugin導入時はエメラルドコストを課金（未導入なら無料動作）。
コマンドはOP専用で、プレイヤーは配布アイテムと看板で操作する設計。旧プラグインのコマンド・権限・configと完全互換です。
