Original plugin by Triacontane.

-----

Dynamically changes the actor's walking, face, and battle graphics.
Changes based on remaining HP, when certain states are active, and when a
switch is turned on.

Switch changes take effect after switching menu screens or moving maps.

Enter the following in the actor's Note field.
<DAG_CHARACTER_HP50:test,2>
# When HP is below 50%, the second image in test.png will be used as the
 walking graphic. (Specify in 10% increments.)

<DAG_FACE_HP10:test,2>
# When HP is below 10%, the second image in test.png will be used as the
 face graphic.
<DAG_BATTLER_HP30:test>
# When HP is below 30%, the test.png will be used as the battler graphic.

<DAG_CHARACTER_MP50:test,2>
# When MP is below 50%, the second image in test.png will be used as the
 walking graphic. (Specify in 10% increments.)

<DAG_FACE_MP10:test,2>
# When MP is below 10%, the second image in test.png will be used as the
 face graphic.

<DAG_BATTLER_MP30:test>
# Sets test.png as the battler graphic when MP is below 30%.

<DAG_CHARACTER_ST5:test,2>
# Sets the second image in test.png as the walking graphic when state [5]
 is active.

<DAG_FACE_ST5:test,2>
# Sets the second image in test.png as the face graphic when state [5] is
 active.

<DAG_BATTLER_ST5:test>
# Sets test.png as the battler graphic when state [5] is active.

<DAG_CHARACTER_SWITCH1:test,2>
# Sets the second image in test.png as the walking graphic when switch [1]
 is ON.

<DAG_FACE_SWITCH1:test,2>
# Sets the second image in test.png as the face graphic when switch [1] is
 ON.

<DAG_BATTLER_SWITCH1:test>
# When switch [1] is ON, set test.png as the battler graphic.


Caution! If you change to an uncached image, the image may flicker or not
display correctly due to the asynchronous loading of JS.
This plugin does not provide any special countermeasures, so please use a
dedicated countermeasure plugin or cache the image beforehand using an
event command or similar.

This plugin does not have any plugin commands.

@plugindesc アクターグラフィックの動的設定プラグイン
@author トリアコンタン

@help アクターの歩行、顔、バトルグラフィックを動的に変化させます。
HPの残量、特定のステート有効時、スイッチON時に変化します。

スイッチによる変動はメニュー画面の切り替えもしくはマップ移動後に有効になります。

アクターのメモ欄に以下の通り入力してください。
<DAG_CHARACTER_HP50:test,2> # HP残量50%以下でtest.pngの2番目の画像を
                            # 歩行グラフィックに指定します。(10%刻みで指定)

<DAG_BATTLER_HP30:test>     # HP残量30%以下でtest.pngを
                            # バトラーグラフィックに指定します。
<DAG_CHARACTER_MP50:test,2> # MP残量50%以下でtest.pngの2番目の画像を
                            # 歩行グラフィックに指定します。(10%刻みで指定)

                            # 顔グラフィックに指定します。
<DAG_BATTLER_ST5:test>      # ステート[5]有効時にtest.pngを
                            # バトラーグラフィックに指定します。
<DAG_CHARACTER_SWITCH1:test, 2> # スイッチ[1]ON時にtest.pngの2番目の画像を
                                # 歩行グラフィックに指定します。

                                # バトラーグラフィックに指定します。

注意！　キャッシュされていない画像に変更した場合、JSの非同期読み込みの仕様で
画像がチラついたり、ただしく表示されない場合があります。
当プラグインでは特に対策は行っていないので、専用の対策プラグインを使うか
事前にイベントコマンドなどでキャッシュを行っていただくようお願いします。

このプラグインにはプラグインコマンドはありません。
