end

#roll(rolls = 1, detailed = false) ⇒ Object

Rolls the Throw and returns the result in different ways according to the params. If detailed=false it will call simple_roll and detailed_roll in case of true. Refer to these methods for more info of the format. Returns the result as simple_roll/detailed_roll if rolls==1 or as Array of simple_roll/detailed_roll if rolls>1.

  results = Array.new
  rolls.times do
    results << simple_roll if !detailed
    results << detailed_roll if detailed
  end
  return results

#to_s ⇒ Object

Returns the Trhow as a string with the format aDx,bDy,cDz+n, where a,b,c are the number of dice, x,y,z are the number of sides and n the offset. Example “D6,D20,D100+8”, etc.
