2. 顺手加固同行的 null 兜底：`(data['doors'] as List?)?.cast<Map>()` 在 `doors` 为 null 时会因 `.firstWhere` 调在 null 上抛 `NoSuchMethodError`，改为 `?? const <Map>[]`，消除同类崩溃。
|
||||
- **回归测试**：新增 `含 warp 但无匹配门的关卡可正常构建（doorId 类型回归）`——构造含 `W` 且 `doors:[]` 的关卡，`Level(data)` 不再抛 TypeError，且 warp 实体的 `doorId` 为 int（回退序号）。
|
||||
- 验证：`flutter test` 22/22、`flutter analyze` 0 error。

## 跳跃手感「稍微飘一点」，但高度与二段高度不变（PHY 微调）
|
||||
用户："跳跃手感再稍微飘一点，但是跳跃高度和其他都不能变"。
|
||||
- **原理**：飘 = 更低重力换更长滞空；但顶点高度由 v²/(2g) 决定，同比例降重力 + 提初速可精确保持高度。物理常量在 `app/lib/src/game/player.dart` 的 `PHY`（web 的 `js/player.js`/`tools/lib-reach.mjs` 在当前仓库已不存在，移植版是唯一定义处，无需再同步求解器）。
|
||||
- **改后值**：GRAV 0.25→0.23、GRAV_FALL 0.32→0.30、GRAV_DJ 0.35→0.322、JUMP 6.6→6.326、DJUMP 6.7→6.420；HSPD/MAXFALL/DJ_INERTIA/WATER_*/ICE_*/SLIDE_* 全未动。
|
||||
- **验证（Python 复刻引擎积分 `vy=min(vy+g,MAXFALL);y+=vy`）**：单跳顶点 83.850px、二段自身 60.800px、总高仍 4.5 格 —— 三者 Δ 均 ≈0；滞空 49→51 帧（+2，≈4%，即"稍微飘"）。
|
||||
- **代价（须告知用户）**：滞空变长使单次跳跃的水平飞行距离增加约 HSPD×2 ≈ 5px，关卡跳跃可达性会略变"更宽松"，这是"飘"的固有副作用；用户明确要求不重调地图，故未动关卡。
|
||||
- **回归测试**：`test/gameplay_test.dart` 新增 `满力单跳顶点高度保持 ≈83.85px（飘但不改高度）`；并把旧的 `JUMP 6.6 / GRAV 0.25` 断言同步改为新值（松键截止量硬编码 -3 未变，只把 0.25→0.23）。
|
||||
- 验证：`flutter test` 23/23、`flutter analyze` 0 error。
