Quick guide to things you can do with the search filters on my search scripts

BDSP Search Filters.md

Every value that is rolled can be checked as a filter. The most important values for ec, pid, isShiny, shinyXor, ivs, ability, genderchar, and nature.

Here are some specific applications.

isShiny

Only show shiny matches.

// Skip any non-shiny match.
if (!isShiny)
    return;

shinyXor

Only show square/star shiny matches. shinyXor is 0 for square and 1-15 otherwise. Keep in mind that xor values greater than 15 exist but are not shiny.

// Skip any shiny matches that don't have xor of 0 (square)
if (isShiny && shinyXor != 0)
    return;

// Skip any that have xor of 0 (square). xor of 0 is automatically shiny.
if (shinyXor == 0)
    return;

ivs

Filters for IVs. They are in the order HP / ATK / DEF / SPA / SPD / SPE. This can look for exact values or ranges.

// Skips if the Pokémon doesn't have a spread of 31/0/31/31/31/31.
if (ivs[0] != 31 || ivs[1] != 0 || ivs[2] != 31 || ivs[3] != 31 || ivs[4] != 31 || ivs[5] != 31)
    return;

// Skips if the Pokémon doesn't have an HP IV greater than 20.
if (ivs[0] <= 20)
    return;

// Skips if the Pokémon doesn't have a spread of 31/0/31/31/31/31 or 31/31/31/0/31/31.
if (!(ivs[0] == 31 && ivs[1] == 31 && ivs[2] == 31 && ivs[3] == 0 && ivs[4] == 31 && ivs[5] == 31)
    && !(ivs[0] == 31 && ivs[1] == 0 && ivs[2] == 31 && ivs[3] == 31 && ivs[4] == 31 && ivs[5] == 31))
    return;

ability

Only in wild/stationary searcher. Searches for ability 1 or 2. Pokémon with ability H aren't rolled in this game.

// Skips if the Pokémon doesn't have ability 1.
if (ability != 1)
    return;

genderchar

Only in wild/stationary searcher. Searches for gender as -, F, or M.

// Skips if the Pokémon isn't male.
if (genderchar != "M")
    return;

nature

Filters a specific nature.

// Skips if the Pokémon isn't Adamant or Jolly.
if (nature != (int)Nature.Adamant && nature != (int)Nature.Jolly)
    return;

advance

Filters any advances that fall within range.

// Shows any advance less than 100.
if (advance < 100)
{
    Console.WriteLine(output);
    return;
}
