UNDERTALE 是一款没有人必须死的独立 RPG。受 EarthBound、Yume Nikki、Cave Story 诸如此类游戏的启发，它因有趣的角色设计、相互联系的音乐和对标准 RPG 梗的曲折而备受赞扬。传说之下有着忠诚的粉丝，曾有好一段时间内这是款不得不玩的游戏。

To do: 待办清单 还有很多版本变更待列出 很多 RG 04 或 03 的文本发生了变化 （应该被 RG 01/02 对话文本替换），待确认。 如果你在与 RG01/02 战斗之前给 Undyne 打电话，会有新的对话文本出现。 将本页拆分为子页面。 添加 Switch 版本的版本差异。 添加 Xbox 版本的版本差异（与其可能的对未使用文本的使用）。

开发者的信息

"不要把图像拷出来"警告

1.00版本

原文	翻译
Please don't upload these huge sprite sheets online. Just 'cause most weird things here ARE used, I'd rather them be seen in context first. wait like a year 1st... if you're just ripping normally seen sprites for spriter's resource or smth idc if you use these 2 make it easier tho	请不要把这些巨大的贴图表上传到网上。 因为这里面大多数奇怪的东西已经被使用了，我只是更想在游戏中让它们被先看到（而不是网上） 等上大概一年吧... 如果你只是为了Spriter's Resource抓取一些常见的贴图或者别的什么的话倒没关系，有贴图表会简单些

abc_1111 包含了一个写给拆包者的话, 特别是给那些来自Spriter's Resource的人，让他们在一年之后再把完整的精灵表上传到网上。

使用Game Maker制作的游戏，比如Undertale,会将所有的精灵储存在一张巨大的PNG格式精灵表上面，而不是将每一个精灵或角色作为单独的文件储存。所以如果有人想要上传精灵表的话，最简单的方法就是上传所有的表格...这会将所有含有剧透的精灵也留在同一张表上。

选择这个奇怪的文件名称的目的是为了让它出现在以字母顺序排列的文件列表的最上面，并且让它看上去更...显眼，这么做并没有起到效果，因为文件列表只有在使用外部程序将精灵分隔成字符串时才能看见。Oops。这张图片在随后的版本中被替换了。

1.001版本

 
you know what i
    HATE?

that's
       bepis

THE TASTE

翻译

 
你知道我

那个
       bepis

'''那味道'''
   那气味
      那纹理

喂...
      你在
          流口水...

版本1.001将之前不要上传的请求替换成了这个关于“bepis”的非常模糊且色情的短笺，“bepis”引用自一个EarthBound中来自Moonside讨厌玩家喜欢的食物的人。Toby Fox是"EarthBound"的粉丝，而Undertale从那部游戏中获得了很多的灵感。“Bepis”是“Pepsi”的一个愚蠢的错误拼写，同时也是开发者觉得很蠢的一个词。

这些文本没有任何实际的含义，并且它可以被视为允许发布精灵表格的许可，因为它替换了先前的请求，并且可以在这封郁郁寡欢的邮件中看出来。

“不要剧透游戏！”警告

abc_123_a.ogg

你好。请-请-请-请-保持一些尊重并不要剧透游戏。因为像你这样爱管闲事的人，在当今不可能保有秘密。请让这一切都成为我们两人之间的秘密。如果你把它发到网上，我将不会制作任何秘密。没人会为此留下印象。这将会是你的错！嘻嘻嘻嘻嘻嘻嘻嘻嘻嘻嘻。

这是一则由八个不同的语音转文字语音组成的音频文件，告诉人们不要把游戏中的秘密发布到网络上。脑子正常的谁会那样做——等一下...

选择这个奇怪的文件名称的目的是为了让它出现在以字母顺序排列的文件列表的最上面，并且让它看上去更显眼。游戏文件夹中其他所有OGG格式的音乐和音效都以“mus_”或“snd_”作为前缀。

该文件在 v1.001 更新中被更新，更新后的版本移除了几乎所有原始音频文件中的内容。

Toby Fox的消息

To do: Changes to this post-1.001.

Part of this game's charm is the mystery of how many options or secrets there are. If you are reading this, please don't post this message or this information anywhere. Or doing secrets will become pointless.
By the way, most of the seemingly unused text/files are used.
If you can find the in-game context for an asset, you can show it off. But if you can't, it probably means you haven't looked hard enough. Anything truly unused I'll probably post myself, later.
Living in a world like this, where people can simply cheat out the answers from the code... your impatience has REALLY damaged you, hasn't it?

翻译

这个游戏的魅力的一部分就是其中的选项和秘密。如果你正在读这个，请不要把这则消息或着信息发布到任何地方。否则制作秘密将变得毫无意义。
顺带一提，大多数看上去没有使用的文本/文件实际上都被用过了。
如果你研究出了一个资源在游戏中的用途的话，你可以将把它展示出来。但是如果你不能的话，可能意味着你找的不够努力。真正没有使用的东西我可能会在以后自己发布。
在人们可以轻易地从代码中作弊得到答案的世界生活...你的不耐烦给你带来了很大的伤害，不是吗？

这则通告被放置在 attention_hackerz_no_2 脚本中，其将这四个字符串分别设入 demonx, demony, demonz 和 demond 变量。 很显然，这个脚本是用来警告破解者们的。因脚本的名称，这些消息被放入了内部字符串列表的开头，这进一步增加了该通告被阅读的机会。

然而，在1.001版本，它被替换为：

Greetings.
You have made yourself completely clear.
Understood.
I, your humble servant, will follow you to the utmost...

翻译

你好。
你已经表达的很清楚了。
了解了。
我，您卑微的仆人，将追随您至死不渝...

这些变量也被重命名为demona, demonb, demonc 和 demond。奇怪的是，1.00版的消息的第一行以及与其关联的变量仍然存在，但是被移入了 scr_namingscreen_check（处理特殊名称的脚本）。

未使用的音乐

mus_kingdescription

玩家死亡后播放的音乐 “Determination” 的更高级版本。根据文件名，它最有可能用于一个与 Asgore 有联系的场景。

mus_dance_of_dog

这种时髦新潮的节奏仅会在你位于“跳舞”的狗错误房间（"dancing" error dog room）的时候播放。乱搞你的存档文件最容易触发这个错误房间。

mus_sigh_of_dog

这种不太时髦新潮的节奏仅会在你位于睡觉的狗错误房间（sleeping error dog room）的时候播放。乱搞你的存档文件最容易触发这个错误房间。

mus_star

使用了来自Star Fox中的乐器的歌曲。游戏中还使用了来自游戏Mario Paint，Final Fantasy VI，Chrono Trigger, Mega Man X，和EarthBound中的乐器，所以这个音乐不会太违和。

According to Toby Fox, this song was intended to play when Madjick's magic orbs turn into healing hearts. However, this proved too difficult to implement because the Core's background music continues into monster battles, so it was scrapped.

(Source: Toby Fox)

mus_f_part3

另一个Flowey的头目战音乐的变奏。 0:20开始的部分被用于场景转换（然而，一个听上去属于那个部分的音效被播放，而不是这个音轨），尽管在正常游玩中，开头的部分是无法听到的。

mus_f_finale_1

“Finale”未被使用的第一部分。这则音频从未被播放，而mus_f_finale_1_l取代了它。它只是Finale第一部分更为简短的版本，很有可能被设计成当玩家在精污花boss战的第二阶段死亡之后重启游戏时播放。

mus_piano

当你在Undertale demo版中立线结尾中杀掉Toriel后，该音乐将会在结尾播放，并作为配乐中最后一首曲目（标题是“Good Night”）出现，但是该歌曲在最终游戏中并没有被使用。

mus_ruinspiano

曲目 “Ruins” 的一个缓慢且庄严的钢琴版。这是“An Ending”第一部分的慢放版本。

mus_birdsong's Hidden Loop

mus_birdsong在当小鸟载着你穿越Waterfall的间隙时播放。然而，这则音乐只会在它淡出之前循环一次。该文件可以被正常循环播放，但是在正常游玩中音乐末尾的一部分被截掉了。

未使用的音频

mus_sfx_a_swipe

一个声音（可能来自Mettaton）发出哼的声音。

mus_sfx_ahh

Flowey说“ahh”的声音。

mus_sfx_voice_triple

Flowey说“三个”（triple）的声音。

mus_silence

Audio file that's, obviously, silence.

snd_curtgunshot

A generic gunshot sound.

mus_f_wind1

An unused longer loop of mus_f_wind2.

mus_f_newlaugh_low

An unused lower pitch variant of mus_f_newlaugh.

mus_woofenstein

An unused longer loop of mus_woofenstein_loop.

Removed Sounds

obj_rainbowbolt_realgen references a sound with the file path music/sfx/sfx_menu_error.ogg, which doesn't exist and is never played by the object anyway.

标题界面菜单

在标题画面按 5 次 Shift 或 X 来触发这个画面。 “Activity Level A” 会在达成 NE（普通结局）后显示。 “Activity Level B” 会在达成 PE（和平结局）后显示。 “Activity Level C” 会在你与 Sans 战斗 2 次或杀死他之后显示。 如果以上条件都不符合，则会显示“No Information”。 在这个界面里输入 BALL 会播放一个声音。

未使用的战斗

RG03和RG04

ACTions

   * Check         * Whisper
   * Touch Glove

   * Error

At the very end of the ACT menu strings is this yet again generic error message, a placeholder for the ACT options of the fight against Asriel's true form.

RG03 and RG04

在游戏文件中的战斗ID 76，为另外两名皇家守卫RG03和RG04设置了一场完整的战斗。Undyue曾经在一段关于在某些日子撤换RG01和RG02的电话交谈中提及RG03和RG04。Despite this, they were actually cut simply because there wasn't any place they could naturally be put in, according to the artbook.

Their battle revolves around them being old friends who had a falling out, and the Pacifist solution is to get them to make up. The guards themselves are slightly incomplete, both using Aaron's defeated sprite as a placeholder, along with not having unique bullet graphics and unique bullet patterns for ACTing, unlike 01 and 02.

Gaster

Gaster has a complete set of stats in the code, all ridiculously high (to the point an enemy given these stats is borderline impossible to damage and getting hit insta-kills Frisk) and consisting only of numerous 6s. They are as follows:

   HP: 666666 
   AT: 66666         DF: 66666
  EXP: -6666       GOLD: -6666

Unused Attacks

Sans

To do: Double check these.

Sans' battle has some unused attacks. They, along with used attacks, are handled in the obj_sansb_body object.

Vertical Platforms - The attack is handled by obj_vplatgen. It has bones along the bottom, with platforms randomly placed and scaled scrolling from top to bottom. Some platforms wave from left to right slightly as well. To dodge, you are to stay on the platforms and not fall to the bottom into the bones. There are 3 variantions to this attack, controlled by obj_vplatgen's (0-indexed) type variable, type 1 to type 2 are simply sped up versions of type 0. Type 2 is directly accessible as attack type (variable a_type) 9 in obj_sansb_body. There's also a unused 6th Alarm event to the generator objects, which spawns randomly positioned bones in the middle of the screen to dodge every 50 frames. Because the platforms are randomly generated in size and position, it can be impossible to avoid getting hit.

Vertical and Horizontal Bones - Fixed bullet patterns with bones coming from positions vertically and horizontally. To dodge, you must maneuver around the bones. Accessible as attack type 10 in obj_sansb_body. There also exists a variantion, accessible as attack type 11 in obj_sansb_body, which is faster and has a different pattern. There is also a "hell" variantion of the first kind of the attack, accessible by setting the hell variable in obj_sansb_body to true, which is harder.

Random Gaster Blasters Variant - The sprites for the blasters are squished to be thin, much like one of the final version's variants, although this time the blasters spawn and shoot faster. This can be seen if a obj_gasterbl_gen is spwaned with type 0, which is not utilized by any coded attack in obj_sansb_body.

Final Attacks Variants - There is also "hell" variants of some of the final attacks. The attack where you have to short hop in between a gap in bones (attack type 1) and the one where you hop over a small white bone with a long blue one right after (attack type 3) is faster when the hell variable in obj_sansb_body is set to true. The platforming attack with bones and platforms scrolling across the screen horizontally has a variant where the platforms scroll slower, which is type 0 of obj_3platgen.

Worth to note that there exists an unused pitch for Megalovania in the code, which is also demonstrated in the video in result of the usage of the skip debug variable. Here's the related code, in the Create event of obj_sansb:

if (skip == true)
{
    con = -1
    with (mypart1)
        bounce = 1
    obj_borderparent.visible = true
    global.msg[0] = scr_gettext("obj_sansb_90") // * Skipped ahead.
    global.mnfight = 3
    global.myfight = 0
    global.faceemotion = 0
    normalfight = 1
    obj_heart.visible = true
    global.flag[271] = 1
    caster_loop(global.batmusic, 0.95, 0.95) // <-- here
}

Mettaton EX

The Mettaton EX battle has some unused attacks. These can be seen if obj_mettattackgen is spawned with the respective attack types set in a global variable called global.attacktype.

To do: Explain better

Attack type 1 - Columns of boxes

Attack type 2 - Columns of boxes weaving from left to right

Attack type 3 - Some arms weaving from left to right?

Attack type 4 - Literally just legs

Attack type 5 - Activated legs weaving from left to right

Attack type 6 - Boxes and bombs scattered everywhere

Attack type 7 - Boxes and bombs scattered everywhere, but faster

Attack type 8 - Tightened bullet board, bombs appear from left and right

Attack type 9 - Less tightened bullet board, bombs appear from left, center and right

Attack type 10 - Columns of boxes and bombs approaching fast. The pattern is replayed after a while

Attack type 11 - Columns of blocks that go upwards when shot

Attack type 12 - Columns of blocks that go upwards when shot, plus sparkle bullets which only appear in the Alphys Lost Soul fight in the final game

Attack type 13 - A lot of mini Mettatons throwing hearts

Attack type 14 - Another lot of mini Mettatons throwing hearts

Attack type 15 - Mini Mettatons throwing sparkles

Attack type 16 - Mini Mettatons throwing sparkles again

Attack type 50 - Some arms with moving yellow block?

Attack type 51 - Fast disco ball

Attack type 52 - Boxes and bombs scattered everywhere, again; also kinda fast

Attack type 55 - Yet again, literally just legs

存档错误房间

游戏中有两个出现烦人狗的房间。他们被用作某种“错误处理”以防游戏出现问题，比如尝试加载损坏的存档文件，或者通过修改存档进入无效或无法进入的房间。

歌曲“mus_dance_of_dog”以随机的音高被用于其中一个错误处理屏幕（左边的那个）。另外一首歌则是“mus_sigh_of_dog”

Unused Item Drop

In the internal monster setup code, there are mentions of item rewards and the chance for an item to drop. This never happens within the game, leaving these global variables unused: itemrewardid and itemrewardchance. Below is an example of the variables in the code.

global.monstername[myself] = scr_gettext("monstername_3") // monstername_3 = "Froggit"
global.monstermaxhp[myself] = 20
global.monsterhp[myself] = 20
global.monsteratk[myself] = 4
global.monsterdef[myself] = 1
global.xpreward[myself] = 10
global.goldreward[myself] = 20
global.itemrewardid = 1
global.itemrewardchance = 50

Old Toriel Dusting Data

scr_getvapordata contains a piece of ASCII pixel art of Toriel's death sprite, spr_torielboss_kneelsmile2, (mostly) composed of 0s (representing black) and 1s (representing white). Along with other data contained in the script, this was meant to be interpreted by an old version of the game's sprite duster, obj_vaporized, which produces dust particles according to it; the final game instead uses obj_vaporized_new like all monsters other than Undyne and Glad Dummy. (The following representation of the data cuts it to lines with 72 characters each, which is half of 144, the original sprite's width.)

Obscured Assets

Snowdin Building Mockups

Placeholder Snowed Inn Lobby

Hidden under the image for the Snowed Inn lobby is a mockup of the rooms layout made of the Snowdin tiles.

Placeholder Snowed Inn Rooms

Like the lobby, there is a placeholder layout for the rooms in Snowed Inn, featuring some not so comfortable beds...

Placeholder Librarby Inside

A mockup of the inside of Snowdin's Librarby, being made of snow and bits of trees.

Early MTT Hotel Outside

Hidden under the MTT Hotel outside image in the respective room (room_fire_hotelfront_2) is an early version of the hotels outside, being made up of tiles instead of being one image. The ground tiles are placeholders, using the ice cave ground, a tile that was used as a placeholder throughout the entirety of Hotland.

Early CORE Entrance

To do: Relocate this somewhere, this doesn't seem to fit here.

Hidden in the right side of the room for CORE's entrance (room_fire_precore) is what seems to be a placeholder version of the entrance, made of Hotland assets. Yes, the background (should) loop like that in the game.

轶事

烦人狗的售价

烦人狗可以卖到999G，在讲价后可以卖到1251G（游戏中最高的物品售价！），但将烦人狗带出生成它的房间后就会消失，所以永远不可能在正常游玩中看到这点。

Mettaton的家

Mettaton的床，上方的墙和电视都有碰撞实体，但是在游戏中不可能到达房间的那个部分。

Death By Glamour Speed

Mettaton EX's battle theme, Death By Glamour, is played at 0.95x speed after the pre-battle intro cutscene, but plays at 0.97x speed instead if Mettaton's dialogue is skipped; this is the value set in scr_battlegroup, the script that defines all of the encounters in the game. The version in the OST plays at full 1x speed, matching neither of these.

Inu Slots Coin Donation Saving

When you save in the Xbox One version, the game stores the value of flag 299 (the amount of coins you donated to the casino Dog Shrine) to global.xbox_coins_donated, then writes the latter into the save file. When you load, the number is read into the latter, and only to the latter for some utterly baffling reason. What's more, the global variable doesn't appear to be used otherwise.

Toy Knife Room Name

The room in the Ruins where the Toy Knife can be found is internally called room_ruins18OLD. This is the only instance of a room labelled as old being used, and there's no non-old version of the room.

Internal Sound File Names

To do: Make the explanation simpler.

There are alternate file names for some sounds and music in the game's code, in the format music/*.ogg, from the phase of development where the game used GameMaker 8 and played external sounds and music through an extension. When the game was migrated to use GameMaker: Studio, it was changed to use GameMaker's native sound system for that instead. So to not change already existing code using the sound extension, compatibility scripts were made, one being caster_load, which converts the filenames that were originally used to pointers to GameMaker sounds by calling scr_getmusindex.

Music/Sound Metadata

As with the demo, music/sound files have some metadata. The ENCODER field seems to be always overwritten by GameMaker: Studio, but there's still some information from FL Studio's LAME encoder.

The "Snoopy, Come Home" metadata refers to the fact that both snd_hit and snd_victor are sampled from the song "Snoopy, Come Home" from the eponymous soundtrack, which Toby seemingly took from an online rip of the original vinyl without changing the metadata.

开发者的疏忽

Mettaton EX战斗论文

在与Mettaton EX的战斗中，有一个“论文”问题环节，你可以输入文字并让他评价。不幸的是，除非按住Ctrl键，输入“x”或者“z”将会结束论文，这导致一些单词（在大部分游玩中）无法打出来。PS4、PS Vita及Nintendo Switch版本的游戏中没有这个疏忽，因为它们使用屏幕键盘。

以下单词无法被触发：

• sexy（性感的）
• foxy（狡猾的）
• tantaliz （挑逗，包括“挑逗”tantalizing和“挑人的”tantalize）

为坠落的人类命名

在PS4和PS Vita版本的游戏中，输入名称“Gaster”将会导致游戏崩溃，而不是预计的重启游戏。
