/**
|
| 2 |
+
* エフェクト開発規約
|
| 3 |
+
* ================
|
| 4 |
+
*
|
| 5 |
+
* 1. 基本方針
|
| 6 |
+
* -----------
|
| 7 |
+
* - BaseEffectクラスは全てのエフェクトの基底クラスとして機能します
|
| 8 |
+
* - 文字の配置や描画に関する基本ロジックは全てBaseEffectクラスで管理します
|
| 9 |
+
* - 継承先のエフェクトクラスでは、見た目に関する設定のみを行います
|
| 10 |
+
*
|
| 11 |
+
* 2. 継承時のルール
|
| 12 |
+
* ----------------
|
| 13 |
+
* - getPaddingメソッドは継承先でオーバーライドしないでください
|
| 14 |
+
* - renderText, renderGlow, renderMainText, renderStrokeメソッドは継承先でオーバーライドしないでください
|
| 15 |
+
* - calculateSize, calculateCoordinatesメソッドは継承先でオーバーライドしないでください
|
| 16 |
+
*
|
| 17 |
+
* 3. 継承先での実装
|
| 18 |
+
* ----------------
|
| 19 |
+
* 以下のメソッドのみを実装/カスタマイズしてください:
|
| 20 |
+
*
|
| 21 |
+
* a) constructor
|
| 22 |
+
* - グローエフェクト(this.glowOptions)の設定
|
| 23 |
+
* - 縁取り(this.strokeOptions)の設定
|
| 24 |
+
*
|
| 25 |
+
* b) setupContext
|
| 26 |
+
* - フォントの基本設定(必須)
|
| 27 |
+
* - グラデーションなどの塗りつぶしスタイルの設定
|
| 28 |
+
*
|
| 29 |
+
* c) applySpecialEffect
|
| 30 |
+
* - 追加の特殊効果が必要な場合のみ実装
|
| 31 |
+
* - 基本的な描画が完了した後に呼び出されます
|
| 32 |
+
*
|
| 33 |
+
* 4. オプション設定
|
| 34 |
+
* ----------------
|
| 35 |
+
* glowOptions = {
|
| 36 |
+
* color: string, // グローの色(16進カラーコード)
|
| 37 |
+
* blur: number, // ぼかしの強さ
|
| 38 |
+
* iterations: number // 重ねがけの回数
|
| 39 |
+
* }
|
| 40 |
+
*
|
| 41 |
+
* strokeOptions = {
|
| 42 |
+
* color: string, // 縁取りの色(16進カラーコード)
|
| 43 |
+
* width: number // 縁取りの太さ
|
| 44 |
+
* }
|
| 45 |
+
*
|
| 46 |
+
* 5. 縦書き対応
|
| 47 |
+
* ------------
|
| 48 |
+
* - 縦書きの処理は全てBaseEffectクラスで管理されています
|
| 49 |
+
* - 継承先で縦書き用の特別な処理は実装しないでください
|
