I would like to make a 3D column of light with squared base.
I began editing the FireSmoke example and since I want just the outline of the squared base to emit particle I have started doing this:

var fire:Emitter3D = new Emitter3D();
fire.counter = new Steady( 60 );

fire.addInitializer( new Lifetime( 2, 3 ) );
var multiZ:MultiZone = new MultiZone();
var yy:Number = 0;
multiZ.addZone(new LineZone(new Point3D(-50,yy,-50), new Point3D(50,yy,-50)));
multiZ.addZone(new LineZone(new Point3D(50,yy,-50), new Point3D(50,yy,50)));
multiZ.addZone(new LineZone(new Point3D(50,yy,50), new Point3D(-50,yy,50)));
multiZ.addZone(new LineZone(new Point3D(-50,yy,50), new Point3D(-50,yy,-50)));

var multiZ2:MultiZone = new MultiZone();
yy = 10;
multiZ2.addZone(new LineZone(new Point3D(-50,yy,-50), new Point3D(50,yy,-50)));
multiZ2.addZone(new LineZone(new Point3D(50,yy,-50), new Point3D(50,yy,50)));
multiZ2.addZone(new LineZone(new Point3D(50,yy,50), new Point3D(-50,yy,50)));
multiZ2.addZone(new LineZone(new Point3D(-50,yy,50), new Point3D(-50,yy,-50)));

fire.addInitializer( new Velocity( multiZ ) );
fire.addInitializer( new Position( multiZ2 ) );
fire.addInitializer( new SharedImage( new FireBlob() ) );

fire.addAction( new Age( ) );
fire.addAction( new Move( ) );
fire.addAction( new LinearDrag( 1 ) );
fire.addAction( new Accelerate( new Vector3D( 0, 40, 0 ) ) );
fire.addAction( new ColorChange( 0xFFFFCC00, 0x00CC0000 ) );
fire.addAction( new ScaleImage( 1, 1.5 ) );
fire.addAction( new RotateToDirection() );

fire.start( );

Now my problem is this: I want light particles to move just on Y axis with no other movement on the other axis.
How do I do this?

Thank you in advance =)]]> http://flintparticles.org/forum/comments.php?DiscussionID=429&Focus=1465#Comment_1465 2010-12-10T16:55:27+00:00 2011-12-11T23:46:48+00:00 Miroku_87 http://flintparticles.org/forum/account.php?u=440

If you want them to only move on the Y axis, you need to set a velocity that only has a Y component. The easiest way to do that is with a PointZone. fire.addInitializer( new Velocity( new ...

fire.addInitializer( new Velocity( new PointZone( new Point3D( 0, -10, 0 ) ) ) );]]> http://flintparticles.org/forum/comments.php?DiscussionID=429&Focus=1490#Comment_1490 2010-12-22T17:45:58+00:00 2011-12-11T23:46:48+00:00 Miroku_87 http://flintparticles.org/forum/account.php?u=440

In this way I can't have a rectangular base =\
