ringAround(rosies); #songsInCode
August 21st, 2009
Felt like making a #songsInCode in haXe
and just for fun actually writing the code and compiling it to see how it might look.
ringAround(rosies);
for(girl in girls){
girl.pocket.fill(new Posies());
}
ashes+=2;
for(girl in girls){
girl.fall(DOWN);
}
result… meh.
You need Flash 10 to view the awesome. It’s a free and fast upgrade.
