From f846a342d18c8bb89f96c6101cc7e704e6bfcb00 Mon Sep 17 00:00:00 2001 From: cabinw Date: Mon, 14 Sep 2026 18:52:37 +0800 Subject: [PATCH] feat(routes): let leftover track pair into a bend instead of straight across MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Playing on a phone, the boards read as a grid of long straight lines crossing everywhere — "一看到这个画面，我脑袋就大". The cause is one line in the filler. Each family lays its signature routes over part of the board and leaves the rest to completePorts, which paired every leftover port with the one straight across. On a switchback board that made 76% of all track pairs diameters and left 43 of 61 cells containing nothing but diameters. Two diameters in one cell always cross, so the straightness and the crossings were never two problems. Preferring a bend halves both, in every family: switchback 76% → 40% straight and 2.38 → 0.92 crossings per cell, crossing 86% → 10%, weave 37% → 5%. It was also quietly suppressing 反差, the swing between a piece looking hopeless and becoming trivial, which the design brief calls the point of the game. Straight routes barely change between orientations. With bends, petals goes from 4.2 to 14.0 and crossing from 4.8 to 28.8 — both had been failing the ≥12 gate and were absent from the level pool entirely. Petals is the family the user singles out as the good-looking one. Generation yield rises with it: four seeds now grow 24 playable levels against 3, at greater rotation depth. createRouteBoard keeps 'straight' as its default so nothing already built moves; the sweep opts in. labs/route-gallery draws both, with the real renderer, so the choice is made by looking rather than by reading a number.

这里画的是轨道本身，不是关卡。先看线好不好看，再谈难度——因为线是玩家一眼就会看到的东西。

+

载入中…

+ +
+

「直穿填充」是那些满屏直线的来源。每个家族只铺自己的签名路线，盘面剩下的端口由填充逻辑配对，而它默认配成对穿的直线。一个格子里两条直线必定相交，所以直线多 = 交叉点多，两件事是同一个原因。

+

它还在压制反差。换成偏好弯道之后，花瓣的反差从 4.2 升到 14.0、双叶跨区从 4.8 升到 28.8、环绕从 10.6 升到 22.9 —— 前两个家族原本是被「反差 ≥12」这道闸门挡在关卡池之外的，其中花瓣正是「像花一样」的那个。
（反差要在盘面上摆好棋子、长成关卡之后才测得出来，所以不在下面这张表里；这几个数字来自六个种子的构造结果。）

六个家族的画风

同一个种子、同一个底板，只换填充方式。数字越低越好：直线占比是对穿轨道占全部轨道的比例，交叉/格是每个格子里互相穿过的轨道对数。
