Literally 2d array and then basic distance formula from 6th grade. Are you stupid op?

I spend my time programming useful shit and contributing to open source software instead of doing programming challenges designed for people who dont know how to program.

>>55632731
were on board, it casually takes 3 minutes to do the program, you complain for no reason ---> get out nigger

>>55632415
Determine what 'cold' or 'hot' means and calculate the distance between the player's point and the object's point and check it against the cold or hot values. Not even worth writing code for honestly, just a waste of time to do so. Even the solution to the problem takes all of 30 seconds to think about and figure out.

>>55632840
Just check the points around the object to detect and tell if the player is here or not, you don't need to calculate the distance for no fucking reason

>>55632903
You want to check every single point around the object as far as the 'hot range' as opposed to doing a single numerical calculation? The fuck?

This is far from beautiful, but it seems to work..

object = rand(9), rand(9)
player = rand(9), rand(9)
player_next = [player[0], player[1]]
tries = 0

until object == player do

  puts "You are at " << player.to_s
  puts "Where do you want to go (u,d,l,r)?"
  direction = gets.chomp
  
  case direction
  when "u"
    if player[1] < 9
      player_next[1] = player[1] + 1      
    elsif
        puts "Not possible!"
        redo
    end
  when "d"
    if player[1] > 0
      player_next[1] = player[1] - 1      
    elsif
        puts "Not psosible!"
        redo
    end
  when "l"
    if player[0] > 0
      player_next[0] = player[0] - 1      
    elsif
        puts "Not possible!"
        redo
    end
  when "r"
    if player[0] < 9
      player_next[0] = player[0] + 1      
    elsif
        puts "Not possible!"
        redo
    end
  else
      puts "Please enter u, d, l or r."
      redo
  end
  
  tries += 1
  if (player[0] - object[0]).abs < (player_next[0] - object[0]).abs \
        || (player[1] - object[1]).abs < (player_next[1] - object[1]).abs then
    puts "colder"
  elsif (player[0] - object[0]).abs > (player_next[0] - object[0]).abs \
        || (player[1] - object[1]).abs > (player_next[1] - object[1]).abs then
    puts "warmer"
  else
      puts "the same"
  end

  player[0] = player_next[0] 
  player[1] = player_next[1]
end

p "You won in #{tries} turns!"

r8 lads. OOP represent

    Vector2 treasure = new Vector2
    {
        X = randomInstance.Next(11),
        Y = randomInstance.Next(11)

    Vector2 playerPosition = new Vector2();

                continue;

                break;

                if (playerPosition.X > 0) playerPosition.X--;
                break;
            case "e":

This is C#, right?
Well, since you asked for feedback..
I think it's generally good, just two points:

At the switch-statement you write:

switch (input) {
    case "n":
        if (playerPosition.Y > 0) playerPosition.Y--;

That's not really OOP, since you didn't encapsulate the data. An OOP version would rater use a setter:

        try
        {
            playerPosition.move("n")
        }
        catch (Exception e)
        {
            Console.WriteLine("You can't move there!");
        }

..with the "move"-method within the Vector2 struct. Other wise I could just write

playerPosition.X = 5000

..and OOP wants to prevent such things.


At another point, you wrote:

      float newLength = (treasure - playerPosition).LengthSquared();

As I understand it you create a new instance of "Vector2" only to calculate the distance between two other "Vector2" structs, and than you just throw the new instance away?

That's a a lot of wasted ressources..

Better would changing the method "LengthSquared" like that:

    public float Distance(Vector2 target)
    {
        return (this.X * target.X) + (this.Y * target.Y);
    }

No need to crete a new instance of Vector2 here..

>>55639834
Thanks senpai.

A try/catch is slower than just comparing values, I didn't want to go full enterprise mode for a simple challenge.

You're absolutely right about the length thing, I kinda overlooked that.
