Discussion I wrote this snake game with my 10 year old today

And I think this is the level most gamedevs should start at

Code (CSharp):

1. using System.Diagnostics;
2. using System.Numerics;
3.  
4. var stopwatch = new Stopwatch();
5. stopwatch.Start();
6. var time = stopwatch.Elapsed;
7.  
8. int width = 100;
9. int heigh = 25;
10. Console.SetWindowSize(width, heigh);
11.  
12. (int X, int Y) food = (0, 0);
13.  
14. var snake = new List<(int X, int Y)>{ (0, 0)  };
15. PlaceFood();
16. var highres = new Vector2(width / 2.0f, heigh / 2.0f);
17. var direction = new Vector2(0, 0);
18. var directionMap = new Dictionary<ConsoleKey, Vector2>
19. {
20.     { ConsoleKey.A, new Vector2(-1, 0) },
21.     { ConsoleKey.D, new Vector2(1, 0) },
22.     { ConsoleKey.W, new Vector2(0, -1) },
23.     { ConsoleKey.S, new Vector2(0, 1) },
24.     { ConsoleKey.LeftArrow, new Vector2(-1, 0) },
25.     { ConsoleKey.RightArrow, new Vector2(1, 0) },
26.     { ConsoleKey.UpArrow, new Vector2(0, -1) },
27.     { ConsoleKey.DownArrow, new Vector2(0, 1) },
28. };
29.  
30.  
31. while (true)
32. {
33.  
34.     if (Console.KeyAvailable)
35.     {
36.         var key = Console.ReadKey(true);
37.         if (directionMap.ContainsKey(key.Key))
38.         {
39.             var newDirection = directionMap[key.Key];
40.             var delta = direction + newDirection;
41.             if (delta != Vector2.Zero) direction = newDirection;
42.         }
43.     }
44.  
45.     var newTime = stopwatch.Elapsed;
46.     var deltaTime = newTime - time;
47.  
48.     time = newTime;
49.  
50.     highres += direction * (float)deltaTime.TotalSeconds * 10;
51.  
52.     if (snake[0].X == (int)highres.X && snake[0].Y == (int)highres.Y) continue;
53.  
54.     var newPos = ((int)highres.X, (int)highres.Y);
55.  
56.     var death = snake.Any(pos => newPos == pos);
57.     if (death)
58.     {
59.         Console.Clear();
60.         Console.SetCursorPosition(1, 1);
61.         Console.WriteLine($"DEATH! Score: {snake.Count}");
62.         Console.ReadLine();
63.         break;
64.     }
65.    
66.     WriteAt(' ', snake[^1]);
67.     for (int i = snake.Count - 1; i > 0; i--)
68.         snake[i] = snake[i - 1];
69.  
70.     snake[0] = newPos;
71.     WriteAt('█', snake[0]);
72.  
73.     if (food.X == snake[0].X && food.Y == snake[0].Y)
74.     {
75.         PlaceFood();
76.         snake.Add((0, 0));
77.     }
78. }
79.  
80. void WriteAt(char c, (int X, int Y) position)
81. {
82.     Console.SetCursorPosition(position.X, position.Y);
83.     Console.Write(c);
84. }
85.  
86. void PlaceFood()
87. {
88.     do
89.     {
90.         var padding = 3;
91.         food = (Random.Shared.Next(padding, width - padding), Random.Shared.Next(padding, heigh - padding));
92.     } while (snake.Any(pos => pos == food));
93.  
94.     WriteAt('F', food);
95. }

 

This has what to do with Unity though?

 

I just wrote this with my cat today

Code (CSharp):

1. ; hello-DOS.asm - single-segment, 16-bit "hello world" program
2. ;
3. ; assemble with "nasm -f bin -o hi.com hello-DOS.asm"
4.  
5.     org  0x100        ; .com files always start 256 bytes into the segment
6.  
7.     ; int 21h is going to want...
8.  
9.     mov  dx, msg      ; the address of or message in dx
10.     mov  ah, 9        ; ah=9 - "print string" sub-function
11.     int  0x21         ; call dos services
12.  
13.     mov  ah, 0x4c     ; "terminate program" sub-function
14.     int  0x21         ; call dos services
15.  
16.     msg  db 'Hello, World!', 0x0d, 0x0a, '$'   ; $-terminated message
