Convoy Tracks(Custom) ----- 护航轨迹 (自定义)

护航轨迹用一套按时刻表调度、基于历史航线的护航队仿真引擎， 替代 UBOAT 原版的随机商船生成。 == 核心特性 == • 5 条预设航线覆盖北大西洋、挪威沿岸、冰岛间隙和比斯开湾 • 船队沿真实的 Kriegsmarine 海军网格航点行驶（网格名提取自游戏地图数据） • 周期调度：每条航线按可配置的时间间隔（小时到天）发船，支持多队并存 • 双组具现化：每支船队包含独立的商船组和护航组，两组 AI 与航速独立 • 风险分级：近岸仅配武装拖网船，冰岛航线配满编驱逐舰护航 • 存档持久化：舰队位置、航点进度、战损数据随战役存档同步 == 性能 == 虚拟舰队仅为数学坐标，仅在 U 艇接近 15km 范围时才生成 3D 实体，离开后销毁 — 远洋船队零性能开销。 Convoy Tracks replaces random merchant spawning with a scheduled, historically-inspired convoy simulation engine. == Features == • 5 pre-configured routes across the North Atlantic, Norway coast, Iceland gap, and Bay of Biscay • Convoys follow real Kriegsmarine naval grid waypoints extracted from the game's map data • Periodic scheduling with configurable intervals (hours to days) and concurrent fleet limits per route • Dual-group realization: merchant and escort groups with independent AI and speed • Risk-scaled escorts — from armed trawlers to Tribal-class destroyers • Full save/load persistence — fleet positions, waypoint progress, and battle damage sync with your campaign == Performance == Virtual fleets are mathematical positions only. 3D entities spawn when your U-boat approaches within 15 km and despawn when you leave — zero overhead for distant convoys.
