4Key音游段位单曲成绩计算的程序实现

前言 其实这个坑我很早以前就想开了，在我刚开始学编程那会就一直想写一个这个东西。但苦于数学进度没达到，要用到加权平均数，这东西我前两天才学到，之前对数学也一直是懒得学的状态，要不然几乎是看不懂那个算法的。 我手头有一个Special-Week写的网页版的单曲成绩计算器，就以这个为研究样本吧。以下简称原作者为sw（如有冒犯请联系修改） 数据结构设计 // 基础的4k类 class Dan4k { constructor(key1, key2, key3, key4, danName) { this.m_key1 = key1; this.m_key2 = key2; this.m_key3 = key3; this.m_key4 = key4; this.m_danName = danName; } } 每一个段（LN、Om），sw都单独写了一个内部类，继承Dan4k。 // lnDan类 class LnDan extends Dan4k { constructor(key1, lnKey1, key2, lnKey2, key3, lnKey3, key4, lnKey4, danName) { super(key1, key2, key3, key4, danName); this.m_lnKey1 = lnKey1; this.m_lnKey2 = lnKey2; this.m_lnKey3 = lnKey3; this.m_lnKey4 = lnKey4; } } // ma段 class MaDan extends Dan4k { constructor(key1, key2, key3, key4, name1, name2, name3, name4, danName) { super(key1, key2, key3, key4, danName); this.m_name1 = name1; this.m_name2 = name2; this.m_name3 = name3; this.m_name4 = name4; } } // reform段 class ReformDan extends Dan4k { constructor(key1, key2, key3, key4, name1, name2, name3, name4, danName) { super(key1, key2, key3, key4, danName); this.m_name1 = name1; this.m_name2 = name2; this.m_name3 = name3; this.m_name4 = name4; } } // om段 class OmDan extends Dan4k { constructor(key1, key2, key3, key4, danName) { super(key1, key2, key3, key4, danName); } } 我打算重写的程序不带LN玩了，我自己也没玩过LN，不清楚是什么机制。那就来看看剩下的几个类。 Dan4k类定义了一个段位的基础属性，但是这个参数key1-4是用来做什么在当前上下文暂且不清楚，是第n首歌的物量吧。 那么由此可以推断，这些类都描述了一个谱面的基本属性： 物量 歌曲名称 段位名称 然后分支匹配数据并计算。我也用C语言实现一个。 // 整个段位信息 typedef struct Dan { // 段位名字 char* dan_name; // 四首歌的名字，用于匹配数据 char* song1_name; char* song2_name; char* song3_name; char* song4_name; // 四首歌的物量 int song1_key; int song2_key; int song3_key; int song4_key; }Dan; 来看看网页版中数据是如何存储的 // MaDan数据 let MaArr = [ new MaDan(813, 955, 907, 654, "Glitch Nerds", "Borealis", "Niflheim", "Moon", "1dan"), new MaDan(1152, 850, 950, 969, "Follow Tomorrow", "Bronze Coffin", "Keigan no Zettaireido", "SakuraMirage", "2dan"), new MaDan(1169, 1143, 974, 1347, "Quon", "Genkyoku o Kirikizamu", "Gin no Kaze", "Adjudicatorz-Danzai-", "3dan"), new MaDan(1400, 1402, 1685, 1599, "Tenkuu no Yoake", "VALLISTA", "Crystal World ~Fracture~", "Zenithalize", "4dan"), new MaDan(1953, 2250, 2166, 1667, "Ten Thousand Tons of Anonymous Letters", "Chips of Notes", "Despair of Elferia", "Kamigami no Asobi", "5dan"), new MaDan(1487, 1424, 1381, 1587, "Sweet Cherry X", "Akasagarbha", "HELLO EveryOne", "DataErr0r", "6dan"), new MaDan(1909, 1814, 1777, 2681, "Fairy Stage", "Xross Infection", "Wave", "Blue Zenith", "7dan"), new MaDan(1962, 1067, 2388, 1772, "The Lost Dedicated", "The Party We Have Never Seen", "Finixe", "Ultimate Dream", "8dan"), new MaDan(1799, 2023, 2283, 1787, "Dusk", "Panic Popn Picnic", "Kick-ass Kung-Fu Carnival", "Yakusoku no kimi", "9dan"), new MaDan(2606, 2188, 2194, 2187, "Chaser", "Loli Fantasy", "Daydream", "Moon Gate", "10dan"), new MaDan(2160, 1952, 1821, 3249, "Border of Life", "Scorpion Dance", "The Island of Albatross", "beautiful loli thing", "ex1"), new MaDan(2871, 2024, 1871, 2452, "Hitsune no youmeiri", "紫阳花-AZISAI-", "love&justice", "message", "ex2"), new MaDan(2327, 1593, 2166, 2200, "Jumble Rumble", "End Time", "++", "Crow Solace", "ex3"), new MaDan(2731, 2653, 2033, 2761, "EDM Jumpers", "line-epsilon", "Contrapasso -paradiso-", "YELL!", "ex4"), new MaDan(3229, 2731, 2561, 2109, "Satori de Pon!", "Legend of Seeker", "Crystal World -Fracture-", "Wizdomiot", "ex5"), new MaDan(1766, 1861, 3171, 1680, "Sepia", "Nopea", "Satori Trisis", "Death", "ex6"), new MaDan(2339, 2461, 2511, 2177, "Paranoia", "Boulafacet", "Paraclete -Miracle-", "Yumemi no Shonen", "ex7"), new MaDan(1929, 2380, 2710, 4675, "Martail Arts", "Gene Disruption", "Paradigm Shift", "Death Melody", "ex8"), new MaDan(3468, 3335, 3698, 5061, "Only my railgun", "-Purgatorium-", "Blue Zenith", "Inner Universe", "exfin"), new MaDan(492, 529, 595, 681, "Ikitoshi Ikerumono", "Rambling Pleat", "Yi Meng Qian Xiao", "White Eternity", "0danv3"), new MaDan(695, 621, 718, 1279, "Rex Incoqnito", "Koiseyo Otome!", "Break", "KING", "1danv3"), new MaDan(1397, 1090, 805, 1212, "Stargazer", "Seyana", "Love Emotion", "Mermaid Girl", "2danv3"), new MaDan(1055, 1489, 1288, 1789, "Koi Kou Enishi", "Onegai!Kon Kon Oinari-sama", "The Last page", "Hoshi ga Furanai Machi", "3danv3"), new MaDan(1865, 1434, 1284, 1839, "Umiyuri Kaiteitan", "Fire in the sky", "Icyxis", "The Crimson Empire", "4danv3"), new MaDan(1282, 1706, 1473, 1939, "Platinum Disco", "Cute na Kanojo", "Reimei Sketchbook", "Joker", "5danv3"), new MaDan(1694, 1636, 1803, 2115, "Chocolate Disco", "Call Me, Beep Me (If You Wanna Reap Me)", "DIE IN THE SEA", "unhappy century", "6danv3"), new MaDan(1701, 1799, 2132, 1899, "Don't Stop The Music", "Six Acid Strings", "Arkadia [Illusion]", "Valkyrie Revolutia", "7danv3"), new MaDan(2237, 2081, 2280, 2000, "Don't let you down", "Yoru ni Kakeru", "Snow Veil -Shoujo to Kemono no Mori-", "Positive Dance Time", "8danv3"), new MaDan(2374, 1899, 2142, 1810, "Kikai Shoujo Gensou", "Cold Planet", "Stray Star", "Unleash
