|
||
* Introduction
|
||
* ============================================================================
|
||
*
|
||
* This plugin allows you to make events that will chase the player or flee
|
||
* from the player when the player enters within range of the event or when the
|
||
* event sees the player.
|
||
*
|
||
* ============================================================================
|
||
* How to Use
|
||
* ============================================================================
|
||
*
|
||
* Insert these lines into the script call window within the Movement Route
|
||
* event to give an event the chase or flee flag.
|
||
*
|
||
* Note: This doesn’t work with players.
|
||
*
|
||
* Script Call lines
|
||
* this._chaseRange = x Event will chase player if reaching x range.
|
||
* this._fleeRange = x Event will flee from player if reaching x range.
|
||
* this._chaseSpeed = x Event's movement speed when chasing.
|
||
* this._fleeSpeed = x Event's movement speed when fleeing.
|
||
* this._sightLock = x Event will flee/chase player for x frames.
|
||
* this._seePlayer = true Requires the event to be able to see player.
|
||
* this._seePlayer = false Doesn't require event to be able to see player.
|
||
* this._alertBalloon = x This balloon will play when player is seen.
|
||
* this._alertSound = x This sound will play when player is seen.
|
||
* this._alertCommonEvent = x This event will play when player is seen.
|
||
*
|
||
* It is best to play this inside of a custom move route for the event at a
|
||
* high frequency rate. Keep in mind these effects only occur after the setting
|
||
* is made and ran, which means upon loading a map, if the event with a low
|
||
* frequency hasn't loaded up 'this._chaseRange = x' in its movement queue yet,
|
||
* the event will not chase the player just yet.

* Introduction
|
||
* ============================================================================
|
||
*
|
||
* このプラグインでは、プレイヤーを追いかけるイベント、もしくは
|
||
* プレイヤーから逃げるイベントを作成することができます。
|
||
* プレイヤーがイベントから一定の距離範囲内に入った時や
|
||
* イベントがプレイヤーを認識した際に発動させることができます。
|
||
*
|
||
* ============================================================================
|
||
* How to Use
|
||
* ============================================================================
|
||
*
|
||
* 下記のコードをスクリプトコールウィンドウ内の、
|
||
* Movement Routeイベント内に挿入することで、そのイベントに
|
||
* 追跡もしくは逃走のフラグを付与することができます。
|
||
*
|
||
* 注＊プレイヤーに対しては無効です。
|
||
*
|
||
* <スクリプトコール>
|
||
* this._chaseRange = x
|
||
* →x の距離内に入った時、イベントがプレイヤーを追いかけます
|
||
* this._fleeRange = x
|
||
* →x の距離内に入った時、イベントはプレイヤーから逃げます
|
||
* this._chaseSpeed = x
|
||
* →追いかける時のイベントの速度 x を決定します
|
||
* this._fleeSpeed = x
|
||
* →逃げる時のイベントの速度 x を決定します
|
||
* this._sightLock = x
|
||
* →追いかける/逃げる際のイベントフレームレート x を決定します
|
||
* this._seePlayer = true
|
||
* →イベントはプレイヤーを認識する必要があります
|
||
* this._seePlayer = false
|
||
* →イベントはプレイヤーを認識する必要がありません
|
||
* this._alertBalloon = x
|
||
* →プレイヤーが認識されると、x というフキダシを表示します
|
||
* this._alertSound = x
|
||
* →プレイヤーが認識されると、x というサウンドを再生します
|
||
* this._alertCommonEvent = x
|
||
* →プレイヤーが認識されると、x というイベントを再生します
|
||
*
|
||
* カスタムした移動ルート内でイベントを再生させる際は、
|
||
* 移動頻度はなるべく高く設定するようにしてください。
|
||
*
|
||
* 設定が完了し有効になるまでは、これらのエフェクトは発動しません。
|
||
* 移動頻度の低いイベントですと、マップロード中に'this._chaseRange = x'の
|
||
* 読み込みを完了できず、プレイヤーを追いかけなくなってしまう可能性があります。
