TMPlugin - Turn Movement ver1.0.2

How to Use:

By adding the <turnMove> tag to an event's notes or the annotation command at the top of its execution, you can apply turn movement to that event only.
You can also use <TurnMove> instead of <turnMove>.

Set the autonomous movement for turn movement events as follows:

To move at the same speed as the player:
Speed 4: Standard
Frequency 3: Standard

To move two steps for every one step the player takes:
Speed 5: Double Speed
Frequency 4: High

To move one step for every two steps the player takes:
Speed 4: Standard
Frequency 1: Lowest

Also, by using the <alwaysTurnMove> tag instead of the <turnMove> tag, turn movement will be performed even if the event is off-screen.

This plugin has been tested with RPG Maker MV Version 1.5.1.

This plugin is distributed under the MIT License and may be freely used, including for commercial purposes, modifications, and redistribution.

Plugin Commands:

stopTurnMove
Disables turn movement for all events.
(Turn movement is enabled at the start of the game.)

startTurnMove
Enables turn movement disabled by stopTurnMove.

skipTurnMove
Moves only turn movement events without moving the player.
The movement amount is one player step.

TMPlugin - ターン移動 ver1.0.2

使い方:

  イベントのメモ、または実行内容の一番上にある注釈コマンド内に
  <turnMove> というタグを書き込むことで、そのイベントにだけ
  ターン移動を適用します。
  <turnMove> の代わりに <ターン移動> でもかまいません。

  ターン移動イベントの自律移動は以下のように設定してください。
    プレイヤーと同じ速度で移動する場合
      速度  4:標準速
      頻度  3:標準

    プレイヤーが１歩移動する間に２歩移動する場合
      速度  5:２倍速
      頻度  4:高

    プレイヤーが２歩移動する間に１歩移動する場合
      速度  4:標準速
      頻度  1:最低

  また、<turnMove> / <ターン移動> タグの代わりに
  <alwaysTurnMove> / <常にターン移動> タグを使用することで、
  イベントが画面外にいてもターン移動が実行されるようになります。

  このプラグインは RPGツクールMV Version 1.5.1 で動作確認をしています。

  このプラグインはMITライセンスのもとに配布しています、商用利用、
  改造、再配布など、自由にお使いいただけます。


プラグインコマンド:

  stopTurnMove
    すべてのイベントのターン移動を無効化します。
    (ゲーム開始時はターン移動が有効になっています)

  startTurnMove
    stopTurnMove で無効化したターン移動を有効化します。

  skipTurnMove
    プレイヤーを移動させずにターン移動イベントのみを移動させます、
    移動量はプレイヤーの１歩分です。
