クリックした点を順にline状に接続し、border-imageのように 矢印画像をセグメント方向へタイル状に繰り返し描画する。 添付の矢印画像は直接取得できないため、同じ意匠の仮アセット (src/asset/arrow-line/arrow-tile.svg)で代替している。 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CpW56yMnmiTNUZg1RuHnKm
tileLength を56→112にし、同じ長さの線上に描画される矢印の数を 半分にした。 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CpW56yMnmiTNUZg1RuHnKm
矢印画像は伸縮させずに固定サイズで描画し、タイル間の空白(間隔)を スライダーで変更できるようにした。以前のtileLengthを引き伸ばして 密度を下げる実装は矢印が変形してしまうため廃止。 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CpW56yMnmiTNUZg1RuHnKm
各セグメントの矢印タイルの下地として、アルファ50%の赤色で 帯状に塗りつぶすようにした。 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CpW56yMnmiTNUZg1RuHnKm
各点を一本のパスでつなぎ、lineJoin: round のstrokeで下地を描画する ことで、セグメントの結合部分の汚れを解消した。 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CpW56yMnmiTNUZg1RuHnKm
見た目の微調整ができるよう、stepを1から0.1に変更した。 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CpW56yMnmiTNUZg1RuHnKm
