Hi
I am almost finished with this asteroid games and I need help duplicating the asteroid here the code I use for the asteroid how can I duplicate it using actionscript

onClipEvent (enterFrame) {
speed = 15;
_rotation += .2;
if (Key.isDown(Key.UP)) {
speed -= 0;
}
if (Key.isDown(Key.DOWN)) {
speed += 0;
}
if (Math.abs(speed)>75) {
speed *= .7;
}
if (Key.isDown(Key.LEFT)) {
_rotation -= 0;
}
if (Key.isDown(Key.RIGHT)) {
_rotation += 0;
}
speed *= .60;
x = Math.sin(_rotation*(Math.PI/180))*speed;
y = Math.cos(_rotation*(Math.PI/180))*speed*-1;
if (!_root.land.hitTest(_x+x, _y+y, true)) {
_x += x;
_y += y;
} else {
speed *= -.8;
}
if (_x>550) {
_x = 0;
}
if (_x<0) {
_x = 550;
}
if (_y>400) {
_y = 0;
}
if (_y<0) {
_y = 400;
}
}
onClipEvent (enterFrame) {
if (_root.player.hitTest(this)) {
_root.player.play();
this.nextFrame();
}
}
onClipEvent (enterFrame) {
for (i=1000; i<1011; i++) {
if (_root["b"+i].hitTest(this)) {
this.nextFrame();
}
}
}
