リリース概要

追加

ろうそく

前回のスナップショットでMinecraft 1.18へ延期されたと思われたろうそくが再実装されました。

それに伴いクリエイティブのインベントリとレシピが再実装されコマンドを使用しなくても入手できるようになりました。

鉢植えされたツツジ・鉢植えされた開花したツツジ

設置された植木鉢にツツジまたは開花したツツジを持った状態で右クリックすると鉢植えされます。

/perfコマンド

統計情報を記録する/perfコマンドが追加されました。

※シングルプレイで試したところ実行できませんでした。（情報求！）

進捗

11件の進捗が追加されました。

新MOBに関する進捗、銅に関する進捗が追加されています。

プレディケート

ルートテーブルや/executeコマンド、ターゲットセレクタ引数で使用されるJSON形式に「lightning_bolt」が追加されました。

スプラッシュ

Minecraft起動直後、右上に表示される文言に11個のテキストが追加されました。

ブロックタグ

「lava_pool_stone_replaceables」と「geode_invalid_blocks」タグが追加されました。

変更

ろうそく

ろうそくに火がついているときと消えているときに使用するテクスチャが使い分けされるようになりました。

看板

輝くイカスミによってテキストが明るくなった文字が更に読みやすくなるように調整されました。

看板が輝いて表示される様子は下記の記事で紹介しています。

ドリップリーフ

大きなドリップリーフと小さなドリップリーフを右手に持った状態のモデルが変更されました。

/debug reportコマンド

/debug reportコマンドが/perfコマンドへ置き換えられたため削除されました。
