Don Kneller ported the UNIX 44 | version to MSDOS (both IBM PCs and DEC Rainbows). 45 | 46 | Other contributors from this era include: 47 | - James McNamara: UNIX install notes, source and patch distribution 48 | - Fred Fish: Termcap support for VMS port 49 | - Daniel Kegel: Enhanced ansi terminal decoding for DOS 50 | - Alexander Perry: Port for Linux 2.x kernel and GCC 3.x 51 | 52 | Kevin Routley contributed various LARN enhancements. Version 12.1 had 53 | a limited distribution. Version 12.2 was distributed to the Usenet 54 | community. Version 12.3 was the last version released by Kevin. 55 | 56 | Someone made 12.4 through 12.4.2, possibly copx according to 57 | roguebasin. Edwin Denicholas took 12.4 alpha 2 and caressed it into 58 | 12.4.3 for Win32. Version 12.4.4 includes a bugfix from Joe Neff. 59 | 60 | Ularn was written in 1987 by Phil Cordier at UC Santa Cruz. 61 | Version 1.5.1 was released by David Richerby and future 1.5.x versions 62 | were developed by Josh Brandt. Version 1.6 was a Windows 32 conversion 63 | and refactor by Julian Olds. Ularn is currently maintained by Josh Bressers. 64 | 65 | Other editions of Larn have been distributed by others, namely 66 | LARN13, dLarn, NLarn, ReLarn, and XLarn. 67 | 68 | JSLarn 12.5.3 is a JavaScript port of Larn and Ularn, by Jason Primeau. 69 | It primarily references the Larn 12.4.4 and Ularn 1.5.4 codebases but takes 70 | inspiration from other versions as well. It includes bug fixes, a global 71 | scoreboard, watching live replays, a weekly challenge mode, mobile support 72 | and updates to balance the game at higher difficulties. 73 | 74 | I hope you enjoy this version of LARN. 75 | 76 | [Larn's version history can be found here](https://github.com/primeau/Larn/blob/master/history.md "Larn's version history can be found here") 77 | 78 | 79 | ## WIZARD mode 80 | There is a WIZARD mode for testing features of the game. To get into WIZARD 81 | mode, type in an underscore '_' and answer the prompt for the password with 82 | '`pvnert(x)`' (do not enter the quotes). Wizards are non-scoring characters that 83 | get magic mapping, everlasting expanded awareness and one of every object in 84 | the game. 85 | 86 | Since it's easy to lose your game due to a browser crash, accidental back 87 | button press, or closed tab, there are 2 new 'wizard' passwords. Using the 88 | password 'checkpoint' will load a backup of a checkpoint file, and 'savegame' 89 | will resurrect a previous save game. These games are excluded from the 90 | scoreboard due to rampant cheating. -------------------------------------------------------------------------------- /src/stairs.js: -------------------------------------------------------------------------------- 1 | 'use strict'; 2 | 3 | 4 | /* 5 | For command mode.

12 | // End Rollbar Snippet -------------------------------------------------------------------------------- /ULARN_SPOILERS.md: -------------------------------------------------------------------------------- 1 | # Ularn Spoiler Guide (Updated 2020) 2 | 3 | Adapted from Phil Cordier's web site: 4 | http://www.cordier.com/ularn/index.html 5 | 6 | 7 | ## A Note on Lemmings - 2020 8 | Lemmings are annoying, but they have been part of the game for 30+ years and 9 | they aren't being changed now. Your best strategy is to fight them in a 10 | dead-end hallway so they can't reproduce. Also, don't forget that they can 11 | be Rambo's best friend. 12 | 13 | ## Lance of Death & Strategy 14 | 15 | In Larn, the basic strategy was to get enough money to buy a Lance of Death, 16 | usually by getting to dungeon level 10, killing or getting around the demon 17 | lord, and getting and then selling the Eye of Larn. This would usually get 18 | you enough money to buy the Lance from the dnd store. You could then go into 19 | the volcano and kill everything in sight with one hit from the Lance. 20 | Well, the Lance is still deadly to all monsters. Demons, on the other hand, 21 | are merely tickled. And there are a LOT more demons (and relatives) in Ularn 22 | than in Larn. 23 | 24 | ## Dungeon and Volcano levels 25 | 26 | There are now 15 levels to the Dungeon, and 5 to the Volcano. Larn had 10 27 | and 3. 28 | 29 | Levels 11 - 15 of the dungeon contain, in addition to all the other nasty 30 | monsters that show up at low levels: 31 | - level 11: 1 demon lord 32 | - level 12: 2 demon lords 33 | - level 13: 3 demon lords 34 | - level 14: 4 demon lords 35 | - level 15: 5 demon lords + 1 demon prince guarding the Eye of Larn. 36 | 37 | The stairs up from level 15 lead to a dead end. You'll need to find another 38 | way up. 39 | 40 | Levels 1 - 5 of the Volcano contain: 41 | - level 1: 1 demon prince 42 | - level 2: 2 demon princes 43 | - level 3: 3 demon princes 44 | - level 4: 4 demon princes 45 | - level 5: 5 demon princes + 1 God of Hellfire guarding the potion of cure 46 | dianthroritis. 47 | 48 | In addition, there are no stairs from level 3 to 4, or from 4 to 5. The only 49 | way to go down is via a pit or trap door. There is guaranteed at least 1 50 | bottomless pit and bottomless trap door on level 5. The rock on levels 3, 4, 51 | and 5 cannot be destroyed via a vaporize rock spell, or in any other way. 52 | 53 | ## Magic Items 54 | 55 | Many of the following magic items will appear in the game: 56 | 57 | #### Eye of Larn 58 | 59 | The Eye now has a very beneficial magic property. If you are carrying the 60 | Eye, demon lords, demon princes, and the God of Hellfire are visible to you. 61 | Otherwise, they are invisible. They will show as follows: 62 | 63 | Monster Character on screen 64 | - Type I Demon Lord: 1 65 | - Type II DemonLord: 2 66 | - Type III Demon Lord: 3 67 | - Type IV Demon Lord: 4 68 | - Type V Demon Lord: 5 69 | - Type VI Demon Lord: 6 70 | - Type VII Demon Lord: 7 71 | - Demon Prince: 9 72 | - God of Hellfire: 0 73 | 74 | #### Sword of Slashing 75 | The Sword of Slashing is quite strong and light, and is impervious to rust. 76 | It raises dexterity by 5. 77 | 78 | #### Bessman's Flailing Hammer 79 | The Hammer is the strongest weapon in the game (excluding the Lance of 80 | Death). It lowers your intelligence by 10, but raises your dexterity and 81 | strength by 10. 82 | 83 | #### Vorpal Blade 84 | The Vorpal Blade is a good all-around weapon that has a 1/20 chance of 85 | beheading any monster that has a head. 86 | 87 | #### Orb of Enlightenment 88 | Carrying the Orb gives permanent expanded awareness. 89 | 90 | #### Orb of Dragon Slaying 91 | Causes attacks against dragons to be much more effective. 92 | 93 | #### Scarab of Negate Spirit 94 | Spirit Nagas and Poltergeists damage is halved if you have the Scarab of 95 | Negate spirit. 96 | 97 | #### Amulet of Invisibility 98 | Causes the 'inv' spell to last much longer. Also extends see invisible while 99 | being carried. 100 | 101 | #### Cube of Undead Control 102 | Vampires, Wraiths, and Zombies damage is halved you have the Cube of Undead 103 | Control. In addition, they can perform no special attacks upon you, like 104 | draining your experience level. 105 | 106 | #### Device of Theft Prevention 107 | If you have this, Nymphs and Disenchantresses cannot steal anything from 108 | you. 109 | 110 | #### Brass Lamp 111 | A genie lives in the brass lamp. If you are lucky, by rubbing the lamp, the 112 | genie will grant you a spell. Be warned though, the genie does not usually 113 | like to be disturbed, and may react unpleasantly. If the genie disappears 114 | (along with the lamp) without granting you a wish, it is still possible to 115 | find him again. But if you are granted a wish, the genie will not wish to be 116 | disturbed again (you only get one wish). 117 | 118 | #### Hand of Fear 119 | Causes the scare monster spell to last much longer. 120 | 121 | #### Talisman of the Sphere 122 | Normally, demons can dispel spheres of annihilation, disenchantresses can 123 | cancel them, and if you have the spell 'cancel' cast, that may cancel the 124 | sphere too. You can also die by touching the sphere. 125 | Carrying the Talisman revokes all of the above 126 | 127 | #### Wand of Wonder 128 | You will not fall down any pits or trap doors if you are carrying the Wand 129 | of Wonder. 130 | 131 | #### Staff of Power 132 | Carrying the staff of power will cancel any attack by a demon lord, 133 | demon prince, wraith, or vampire 75% of the time. It increases wisdom by 10. 134 | 135 | #### Slayer 136 | Demon lords and demon princes attacks are halved if you are wielding the sword 137 | Slayer. Slayer essentially acts as a Lance of Death, but only against 138 | demons. It is otherwise a good strong weapon against other monsters. You 139 | will only find Slayer somewhere below dungeon level 10, or in the volcano. 140 | It increases intelligence by 10. 141 | 142 | #### Elven Chain 143 | Strong and light, impervious to rust. 144 | 145 | #### Amulet of Life Preservation (added in Ularn 1.6) 146 | Prevents drain life attacks. 147 | 148 | ## New spell 149 | I've added a 'make wall' spell, that creates a wall in the place you 150 | specify. The code is 'mkw'. 151 | 152 | ## Elevators 153 | 154 | Watch out for express elevators. They can be good or bad, depending on which 155 | direction they go (up or down). 156 | 157 | ## Time limit 158 | 159 | The time limit for solving the game has been increased from 300 mobuls to 160 | 400 mobuls. 161 | 162 | ## Dealer McDope's 163 | On request from several unsavory types here at UC Santa Cruz, I added Dealer 164 | McDope's Pad. He will show up usually somewhere in the lower level of the 165 | dungeon. Visiting Dealer McDope's will offer you the chance to buy such 166 | interesting and stimulating items as: 167 | - Killer Speed 168 | - Groovy Acid 169 | - Monster Hash 170 | - Trippy Shrooms 171 | - Cool Coke 172 | 173 | You "use" a drug by dropping it, and then moving on top of it for more 174 | instructions.
