What in the world is this?

RE: XONIX - DANILIN - 06-04-2022

I have long dreamed of creating a sketch
about a flying balloon from scratch
and created it in an hour

I suppose locals could have composed
much shorter than my program in past

Program create a random area
and in a random place ball starts and flies

There was an idea to apply "screen(y-1, x+1) =35"
however a non-optimal program would become longer

My program is universal:
creating an array of coordinates
there will be a lot of flying balls

Wasn't Xonix the company who made those "double ender" cartridges for the Atari 2600 back in the '80s?

Expanding on the subject of WTH?
Code: (Select All)
_Font 8
m = 3: n = 2
restart:
_Title Str$(m) + " x" + Str$(n): Cls
x = 1: y = 1: dx = 1: dy = 1: c = 0
move:
Locate y + 1, x + 1: Print Chr$(219);
If x + dx < 1 Or x + dx > m Then dx = -dx
x = x + dx
If y + dy < 1 Or y + dy > n Then dy = -dy
y = y + dy
Color 0, 15
Locate y + 1, x + 1: Print "X";
Color 15, 0
_Limit 30
c = c + 1
If c > (m * n) Then
    toggle = 1 - toggle
    If toggle Then n = n + 2 Else m = m + 2

    _Delay 1
    GoTo restart
Else
    GoTo move
