Poke Engine

An engine for searching through Pokémon battles (singles only).

This is not a perfect engine

This battle engine is meant to capture important aspects of Pokémon for the purposes of competitive single battles. It is nowhere near as complete or robust as the PokemonShowdown battle engine.

Running Directly

Building

Make sure you have Rust / Cargo installed.

Features are used to conditionally compile code for different generations of Pokemon. The simplest way to build the project is with the Makefile.

e.g. To build for generation 4:

make gen4

Run with

./target/release/poke-engine

Generations 4 through 8 are available

Usage

There are several ways to interact with the engine through subcommands:

1. Generate Instructions

poke-engine generate-instructions --state <state-string> -o <s1_move> -t <s2_move>

Generate and display the different Instructions that could be applied to the state if side 1 and side 2 used the given moves.

e.g.

poke-engine generate-instructions --state "alakazam,100,Psychic,Typeless,251,251,MAGICGUARD,LIFEORB,121,148,353,206,365,None,0,25.5,PSYCHIC;false;16,GRASSKNOT;false;32,SHADOWBALL;false;24,HIDDENPOWERFIRE70;false;24,NONE;true;32,NONE;true;32=skarmory,100,Steel,Flying,271,271,STURDY,CUSTAPBERRY,259,316,104,177,262,None,0,25.5,STEALTHROCK;false;32,SPIKES;false;32,BRAVEBIRD;false;24,THIEF;false;40,NONE;true;32,NONE;true;32=tyranitar,100,Rock,Dark,404,404,SANDSTREAM,CHOPLEBERRY,305,256,203,327,159,None,0,25.5,CRUNCH;false;24,SUPERPOWER;false;8,THUNDERWAVE;false;32,PURSUIT;false;32,NONE;true;32,NONE;true;32=mamoswine,100,Ice,Ground,362,362,THICKFAT,NEVERMELTICE,392,196,158,176,241,None,0,25.5,ICESHARD;false;48,EARTHQUAKE;false;16,SUPERPOWER;false;8,ICICLECRASH;false;16,NONE;true;32,NONE;true;32=jellicent,100,Water,Ghost,404,404,WATERABSORB,AIRBALLOON,140,237,206,246,180,None,0,25.5,TAUNT;false;32,NIGHTSHADE;false;24,WILLOWISP;false;24,RECOVER;false;16,NONE;true;32,NONE;true;32=excadrill,100,Ground,Steel,362,362,SANDFORCE,CHOICESCARF,367,156,122,168,302,None,0,25.5,EARTHQUAKE;false;16,IRONHEAD;false;24,ROCKSLIDE;false;16,RAPIDSPIN;false;64,NONE;true;32,NONE;true;32=0=0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;==0=0=0=0=0=0=0=0=0=0=false=NONE=false=false=switch:0=false/terrakion,100,Rock,Fighting,323,323,JUSTIFIED,FOCUSSASH,357,216,163,217,346,None,0,25.5,CLOSECOMBAT;false;8,STONEEDGE;false;8,STEALTHROCK;false;32,TAUNT;false;32,XSCISSOR;false;24,QUICKATTACK;false;48=lucario,100,Fighting,Steel,281,281,JUSTIFIED,LIFEORB,350,176,241,177,279,None,0,25.5,CLOSECOMBAT;false;8,EXTREMESPEED;false;8,SWORDSDANCE;false;32,CRUNCH;false;24,ICEPUNCH;false;24,AURASPHERE;false;32=breloom,100,Grass,Fighting,262,262,TECHNICIAN,LIFEORB,394,196,141,156,239,None,0,25.5,MACHPUNCH;false;48,BULLETSEED;false;48,SWORDSDANCE;false;32,LOWSWEEP;false;32,DRAINPUNCH;false;16,PROTECT;false;16=keldeo,100,Water,Fighting,323,323,JUSTIFIED,LEFTOVERS,163,216,357,217,346,None,0,25.5,SECRETSWORD;false;16,HYDROPUMP;false;8,SCALD;false;24,SURF;false;24,HIDDENPOWERICE70;false;24,CALMMIND;false;32=conkeldurr,100,Fighting,Typeless,414,414,GUTS,LEFTOVERS,416,226,132,167,126,None,0,25.5,MACHPUNCH;false;48,DRAINPUNCH;false;16,ICEPUNCH;false;24,THUNDERPUNCH;false;24,BULKUP;false;32,PAYBACK;false;16=toxicroak,100,Poison,Fighting,307,307,DRYSKIN,LIFEORB,311,166,189,167,295,None,0,25.5,DRAINPUNCH;false;16,SUCKERPUNCH;false;8,SWORDSDANCE;false;32,ICEPUNCH;false;24,POISONJAB;false;32,SUBSTITUTE;false;16=0=0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;==0=0=0=0=0=0=0=0=0=0=false=NONE=false=false=switch:0=false/none;5/none;5/false/false" -o shadowball -t breloom

3. Iterative Deepening

poke-engine iterative-deepening --state <state-string> --time-to-search-ms <time>

Similar to expectiminimax, search through the state but use iterative deepening. Searches for the given amount of time, then returns the best move found.

e.g.

poke-engine iterative-deepening --state "alakazam,100,Psychic,Typeless,251,251,MAGICGUARD,LIFEORB,121,148,353,206,365,None,0,25.5,PSYCHIC;false;16,GRASSKNOT;false;32,SHADOWBALL;false;24,HIDDENPOWERFIRE70;false;24,NONE;true;32,NONE;true;32=skarmory,100,Steel,Flying,271,271,STURDY,CUSTAPBERRY,259,316,104,177,262,None,0,25.5,STEALTHROCK;false;32,SPIKES;false;32,BRAVEBIRD;false;24,THIEF;false;40,NONE;true;32,NONE;true;32=tyranitar,100,Rock,Dark,404,404,SANDSTREAM,CHOPLEBERRY,305,256,203,327,159,None,0,25.5,CRUNCH;false;24,SUPERPOWER;false;8,THUNDERWAVE;false;32,PURSUIT;false;32,NONE;true;32,NONE;true;32=mamoswine,100,Ice,Ground,362,362,THICKFAT,NEVERMELTICE,392,196,158,176,241,None,0,25.5,ICESHARD;false;48,EARTHQUAKE;false;16,SUPERPOWER;false;8,ICICLECRASH;false;16,NONE;true;32,NONE;true;32=jellicent,100,Water,Ghost,404,404,WATERABSORB,AIRBALLOON,140,237,206,246,180,None,0,25.5,TAUNT;false;32,NIGHTSHADE;false;24,WILLOWISP;false;24,RECOVER;false;16,NONE;true;32,NONE;true;32=excadrill,100,Ground,Steel,362,362,SANDFORCE,CHOICESCARF,367,156,122,168,302,None,0,25.5,EARTHQUAKE;false;16,IRONHEAD;false;24,ROCKSLIDE;false;16,RAPIDSPIN;false;64,NONE;true;32,NONE;true;32=0=0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;==0=0=0=0=0=0=0=0=0=0=false=NONE=false=false=switch:0=false/terrakion,100,Rock,Fighting,323,323,JUSTIFIED,FOCUSSASH,357,216,163,217,346,None,0,25.5,CLOSECOMBAT;false;8,STONEEDGE;false;8,STEALTHROCK;false;32,TAUNT;false;32,XSCISSOR;false;24,QUICKATTACK;false;48=lucario,100,Fighting,Steel,281,281,JUSTIFIED,LIFEORB,350,176,241,177,279,None,0,25.5,CLOSECOMBAT;false;8,EXTREMESPEED;false;8,SWORDSDANCE;false;32,CRUNCH;false;24,ICEPUNCH;false;24,AURASPHERE;false;32=breloom,100,Grass,Fighting,262,262,TECHNICIAN,LIFEORB,394,196,141,156,239,None,0,25.5,MACHPUNCH;false;48,BULLETSEED;false;48,SWORDSDANCE;false;32,LOWSWEEP;false;32,DRAINPUNCH;false;16,PROTECT;false;16=keldeo,100,Water,Fighting,323,323,JUSTIFIED,LEFTOVERS,163,216,357,217,346,None,0,25.5,SECRETSWORD;false;16,HYDROPUMP;false;8,SCALD;false;24,SURF;false;24,HIDDENPOWERICE70;false;24,CALMMIND;false;32=conkeldurr,100,Fighting,Typeless,414,414,GUTS,LEFTOVERS,416,226,132,167,126,None,0,25.5,MACHPUNCH;false;48,DRAINPUNCH;false;16,ICEPUNCH;false;24,THUNDERPUNCH;false;24,BULKUP;false;32,PAYBACK;false;16=toxicroak,100,Poison,Fighting,307,307,DRYSKIN,LIFEORB,311,166,189,167,295,None,0,25.5,DRAINPUNCH;false;16,SUCKERPUNCH;false;8,SWORDSDANCE;false;32,ICEPUNCH;false;24,POISONJAB;false;32,SUBSTITUTE;false;16=0=0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;==0=0=0=0=0=0=0=0=0=0=false=NONE=false=false=switch:0=false/none;5/none;5/false/false" -t 100

5. Calculate Damage

poke-engine calculate-damage --state <state-string> -o <s1_move> -t <s2_move>

State Representation

When running directly, the engine parses the state of the game from a string.

Properly representing the state of a Pokémon battle gets really complicated. See the doctest for State::deserialize in serialize.rs for the source of truth on how to parse a state string.
