Introduction

To celebrate Monster Hunter 4 Ultimate launch on new 3DS (February 13th), here's a King of the Hill themed on this game.

You are a novice hunter, who'll take part in a tournament consisting of 5 consecutives hunts. At the end of these hunts, hunters will be ranked depending on the damage they dealt to monsters and of course wether they slayed it or have been vanquished by it. Also, as a novice, you'll have to stick to the weapon you choose until you are more experienced.

Lexicon

ATK : Attack
DEF : Defense
HP : Health Points
NRG : Energy
GRD : Guard
SPD : Speed
SHP : Sharpness
AGR : Aggressivity
POT : Potion
RAT : Ration
WHE : Whetstone

Principle

Hunters can choose among a variety of 4 weapons :

              |   Id   |  ATK  |  GRD  |  SPD  |
------------------------------------------------
Great Sword   |   GS   |   7   |   2   |   2   |
Dual Blade    |   DB   |   3   |   0   |   7   |
Lance         |   LA   |   5   |   4   |   3   |
Hammer        |   HA   |   9   |   0   |   1   |

The 5 monsters to hunt are :

              |   HP   |  ATK  |  DEF  |
----------------------------------------
Yian Kut-ku   |  1500  |   5   |   4   |
Rathian       |  1800  |   7   |   4   |
Rathalos      |  1800  |   4   |   7   |
Tigrex        |  2000  |   8   |   6   |
Fatalis       |  2500  |  11   |   7   |

When the game begins, you have to choose a weapon. Then, for each of the 5 hunts, you'll be split among teams of 4 players and you'll start hunting.

Each hunter basic stats are :

              |   HP  |  NRG  |  DEF  |  SHP  |  AGR  |
-------------------------------------------------------
Hunter        |  100  |  100  |   5   |   4   |   0   |

Stats can't go beyond their initial values (i.e. taking a potion with 50HP only restores your health up to 100HP).

Each hunter starts with :

              |  POT  |  RAT  |  WHE  |
---------------------------------------
Hunter Items  |   5   |   5   |   5   |

The controller provides you with input via command arguments, your program has to output via stdout.

Syntax

Output (preparation)
Before the game starts, the controller invokes you submission without arguments. This means you have to choose one of the 4 weapon by outputing its Id. You'll keep this weapon till the end of the game.

You need to output : WeaponID

For example : GS.

Input
Each time your program is called, it will receive arguments in this format (newlines not part of the input an only used for formatting):

Round;YourPlayerId;Monster_ATK;Monster_DEF;Monster_HP;Monster_TargetId;Monster_NextMoveId;
PlayerId_WeaponId_ATK_DEF_HP_NRG_GRD_SPD_SHP_AGR_POT_RAT_WHE_CurrentCombo;
PlayerId_WeaponId_ATK_DEF_HP_NRG_GRD_SPD_SHP_AGR_POT_RAT_WHE_CurrentCombo;
PlayerId_WeaponId_ATK_DEF_HP_NRG_GRD_SPD_SHP_AGR_POT_RAT_WHE_CurrentCombo;
PlayerId_WeaponId_ATK_DEF_HP_NRG_GRD_SPD_SHP_AGR_POT_RAT_WHE_CurrentCombo

Example input

3;3;5;5;1164;2;S;
0_LA_5_5_75_45_4_3_2_55_5_5_5_AA;
1_HA_9_5_75_100_0_1_3_321_5_5_5_N;
2_GS_7_5_75_35_2_2_2_59_5_5_5_BB;
3_DB_3_5_75_78_0_7_2_0_5_5_5_AB

Here, you see it is the 3rd minute (starts at 1) and you are player 3. You are carrying Dual Blades, you have 3 ATK, 5 DEF, 75 HP, 78 NRG, 0 GRD, 7 SPD, 2 SHP, 5 POT, 5 RAT, 5 WHE and your current combo is A->B.

Output

See gameplay.

Gameplay

Teams of 4 hunters are made randomly at the start of each hunt. If there are not enough hunters to make teams, the game will automatically add 1 or more of the 4 "helper" (Felyne, Melynx, Palico or Koneko) choosen randomly to reach desired numbers.

Each hunt lasts 50 minutes, and you can take 1 action per minute (i.e. 50 actions per hunt). For each of these 50 minutes, you'll need to output a letter corresponding to the action you'll take (see actions).

Hunters go first (in a random order choosen at the beginning), then the monster executes its action (which was provided as Monster_NextMoveId). So each minute goes like this : Hunter 1 > Hunter 2 > Hunter 3 > Hunter 4 > Monster > Next minute...

On the first minute, the monster will always use O (see actions). Each turn after its action, the monster will choose its next target by selecting the hunter with the highest AGR value. AGR decreases by 30 per minute.

If the monster or all hunters are killed, the hunt stops. The hunters are revived after each hunts, and their stats, items, combos and actions are reset to their default values.

Hunters' actions

A : Attack A [Requires NRG]

B : Attack B [Requires NRG]

C : Attack C [Requires NRG]

G : Guard [Requires 15 NRG. Can only be used if the weapon has GRD > 0. Activates GRD stat in damage formula for next turn.]

D : Dodge [Requires 30 NRG. Completely dodge damage for next turn.]

W : Wait [Restores 30 NRG. Does nothing else.]

T : Taunt [Restores 80 NRG. Increases AGR by 300.]

P : Potion [Requires 1 POT. Restores 90 HP. Reduces DEF by 2 for next turn.]

R : Ration [Requires 1 RAT. Restores 30 HP AND 50 NRG. Reduces DEF by 2 for next turn.]

S : Sharpen [Requires 1 WHE. Restores SHP to 4. Reduces DEF by 2 for next turn.]

Monsters' actions

Monsters choose their action randomly.

O : Observe (5% chance) [Does nothing.]

A : Attack (40% chance) [Attacks target (defined in Monster_TargetId).]

R : Roar (10% chance) [Stuns everyone. Hunters do nothing next turn.]

F : Fly (10% chance) [Completely dodge every attack next turn.]

C : Charge (15% chance) [Attacks target (defined in Monster_TargetId). Completely dodge every attack next turn.]

S : Spin (20% chance) [Attacks every hunter.]

Attacks & Combos

Each weapon can be used to launch 3 differents attacks : A, B and C.

Each attacks requires and consumes NRG according to this formula : energy = floor(100 / (SPD + 2))

Damages are calculated with this formula : damage = ATK * (10 + SHP - DEF [- GRD]). GRD is only applied if the hunter is currently guarding (see actions). When a hunter is using an item (see actions), his DEF is reduced by 2. Each hit on a monster reduces SHP by 1 till the minimum of 1. Monsters have a SHP of 0. Each damage inflicted to a monster increases AGR by the same value.

If you manage to chain attack to create a specific combo, your damage will be multiplicated by the corresponding bonus. Any action other than an attack reset your current combo, and combo with reset = 1 will also reset it.

              |   Combo                    | Bonus | Reset |
------------------------------------------------------------
Great Sword   | B -> B -> A                |   3   |   1   |
Great Sword   | B -> B -> B -> C           |   4   |   1   |
------------------------------------------------------------
Dual Blade    | C -> C                     |   2   |   1   |
Dual Blade    | A -> B -> A -> B           |   3   |   0   |
Dual Blade    | A -> B -> A -> B -> A      |   4   |   0   |
Dual Blade    | A -> B -> A -> B -> A -> C |   5   |   1   |
------------------------------------------------------------
Lance         | B -> B -> B                |   3   |   1   |
Lance         | A -> A -> A                |   2   |   0   |
Lance         | A -> A -> A -> C           |   4   |   1   |
------------------------------------------------------------
Hammer        | B -> B -> A                |   2   |   1   |
Hammer        | C -> C -> A                |   2   |   1   |

Markdown pro-tip: you can force a single line break by terminating a line with two space. No need for <br>. (Related HTML5 pro-tip: there is no such thing as a self-closing tag. <br/> is only permitted for legacy reasons and is semantically equivalent to <br>.) — Martin Ender, Feb 25, 2015 at 16:07
What does "stick to de weapon you choose until you are more experienced" mean? can the player change weapon at each encounter? are there going to be "better" weapons later? — rorlork, Feb 25, 2015 at 16:53
@Geobits Yes, I upgraded my game launcher so that I can start as many games as I want to get final results. I'm thinking of 100 or 1000 games for the final results (10 games take approximately 15 minutes on my computer). — Thrax, Mar 4, 2015 at 15:24

Roran seems to like hitting without much concern for his life. He managed to die fighting a Yian Kut-ku! He came last in my test game. — Thrax, Feb 26, 2015 at 7:57

Weasel Will

I'm not sure I entirely trust this guy, but his blades are nice to have around in case of trouble.

I call him Weasel because he tends to score best when Fatalis kills everyone else and he dodges until the time limit. I like to imagine he loots the corpses before heading out. — Geobits, Feb 27, 2015 at 2:49
This guy manages to make current hunters fail almost every hunt! But he does dodge pretty well! — Thrax, Feb 27, 2015 at 7:52

While this one doesn't seem to score particularly well, I like having him as a partner. He actually makes a pretty good tank by keeping the monster's attention and dodging attacks. — Spencer, Mar 2, 2015 at 21:02

@justhalf For now, and my guess is RNG Jesus had a lot to do with its victory. — Thrax, Mar 4, 2015 at 7:46
If you suspect RNG has a lot to do with this, then I think we can increase the number of hunts to, say, 30 or 50. — justhalf, Mar 4, 2015 at 7:47
@justhalf I think I'll do 100 hunts for the final game, but I'll only do 10 for test games. — Thrax, Mar 4, 2015 at 7:49

Save as lancer.js, run with node lancer

There seems to be quite a bit of variety in this challenge depending on how the RNG causes the monster to behave and, more importantly, the team makeup. I've seen this entry come in anywhere from a commanding lead to dead last. Keeps things interesting. — Spencer, Mar 2, 2015 at 21:01
Lancer did pretty well in the test games! First in 3 of 5 games. — Thrax, Mar 3, 2015 at 16:04
