Whiteout survival build times calculator

build_times.rb

#! /usr/bin/env ruby

# This is useful if you want to be able to see how much your
# 20% chief daily bonus + pet build buff may affect your build time.
#
# Usage: build_time <build_time> <current_speed_percent> <adjust_by_percent>
#
# Example: build_time "2d 3h 4m" 84.7 22

class BuildTime
  attr_accessor :total_mins

  def initialize(str_time, current_speed_percent)
    @str_time = str_time
    @current_speed_percent = current_speed_percent
    @total_mins = parse_time(@str_time)
  end

  def adjust(*percentages)
    percentages = Array(percentages)
    puts percentages
    @total_mins /= (1 + @current_speed_percent + percentages.sum)
  end

  def to_s
    days, hours, mins = mins_to_units
    "#{days}d #{hours}h #{mins}m"
  end

  def mins_to_units
    mins = @total_mins.dup.to_i
    hours = mins / 60
    mins -= hours * 60
    days = hours / 24
    hours -= days * 24
    [days, hours, mins]
  end

  def parse_time(str_time)
    /((?<days>\d{1,2})d)?( ?(?<hours>\d{1,2})h)?( ?(?<mins>\d{1,2})m)?\z/ =~ str_time
    @total_mins = days.to_i * 24 * 60 + hours.to_i * 60 + mins&.to_i
  end
end

current_speed_percent = ARGV[1].to_f / 100
adjust_by = ARGV[2].to_f / 100
build_time = BuildTime.new(ARGV[0], current_speed_percent)

puts "parsed build time: #{build_time}"
puts "total minute: #{build_time.total_mins}"

puts "adjusting build time by #{adjust_by}"
build_time.adjust(adjust_by)
puts "adjusted build time: #{build_time}"
puts "total minute: #{build_time.total_mins.floor}"

Example output:

➜  whiteout_survival git:(main) ./build_time "5d 0h 33m" 84.7 32
parsed build time: 5d 0h 33m
total minute: 7233
adjusting build time by 0.32
0.32
adjusted build time: 2d 7h 37m
total minute: 3337

You can find your current "Construction Speed" in "Bonus Overview" -> "Growth". This becomes the second argument passed to the script. That is what the 84.7 is in my example.
