Question

class Airplane
  attr_reader :weight, :aircraft_type
  attr_accessor :speed, :altitude, :course

  def initialize(aircraft_type, options = {})
    @aircraft_type  = aircraft_type.to_s 
    @course = options[:course.to_s + "%"] || rand(1...360).to_s + "%" 
  end 

How I can use minimum and maximum allowable values ​​for the hash in initialize from 1 to 360?

Example:

airplane1 = Airplane.new("Boeing 74", course: 200)
p radar1.airplanes
=> [#<Airplane:0x000000023dfc78 @aircraft_type="Boeing 74", @course="200%"]

But if I set to course value 370, airplane1 should not work

Answer 1

This could be refactored i’m sure but this is what i came up with

class Plane

  attr_reader :weight, :aircraft_type
  attr_accessor :speed, :altitude, :course

  def initialize(aircraft_type, options = {})
    @aircraft_type = aircraft_type.to_s 
    @course = options[:course] || random_course
    check_course  
  end

  def check_course
   if @course < 1 or @course > 360
      @course = 1
      puts "Invalid course. Set min"
     elsif @course > 360
      @course = 360
      puts "Invalid course. Set max"
     else
      @course = @course
     end
   end

   def random_course
    @course = rand(1..360)
   end

end
