ok, I'm not talking about neon lights or something :P

I'm writing a small perl clone of PONG -- you know, the game everyone played at least once

this is the code so far:

#!/usr/bin/perl

$|=1;

use Term::ReadKey;

($w, $h) = GetTerminalSize;

ReadMode 3;

$x1 = 3; $y1 = 3;
$dx = 0.05; $dy = 0.05;

print "\e[H";
print "\n" x ($h-2); print " " x ($w/2-5);
print "##########\r";
$x=($w/2-5);


while (1) {

  $key = ReadKey -1;

  if ($key eq "d") {$x++; if ($x>($w-10)) {$x=($w-10)};
                    print "\e[H"; print "\n" x ($h-2); print "\r"; pri
+nt "\e[K"; print " " x $x; print "##########\r";}
  if ($key eq "a") {$x--; if ($x<0) {$x=0};
                    print "\e[H"; print "\n" x ($h-2); print "\r"; pri
+nt "\e[K"; print " " x $x; print "##########\r"; }

print "\e[H";
for (0..($h-3)) {print " " x ($w); print "\n"}
print "\e[H\n\n\n"; print "\n" x $y1; print "\r\e[K"; print " " x $x1;
+ print "O\r";

$x1 = ($x1 + $dx);
$y1 = ($y1 + $dy);

if ( ($y1)>=($h-5) || $y1<=0) {$dy *= -1}
if ( ($x1)>=($w-1) || $x1<=0) {$dx *= -1}

}

ReadMode 0;

yes - there isn't any "my" or strict or warnigns... but that's not the problem. and yes - the ball bounce in its own way, don't caring about the pad

before go ahead, I've got this problem, when you run that code, the cursor of the ball made everything "flashing" and make the game annoying

how can I avoid this annoying flashing ?

(sorry for my bad english)
