I'm trying to adapt the Fireworks example to use it with papervision, but I would like have a little bit more uniform distribution on a sphere or disk zones like in the example ...

demo: http://clockmaker.jp/labs/as3_pv3d_gw_fireworks/main.swf

Here are my code for the DiskBang:

public class DiscBang extends Emitter3D
{
public function DiscBang( position : Point3D, color : uint )
{
counter = new Blast( 50 );

addInitializer( new ColorInit(color, color) );
addInitializer( new Position( new PointZone( position ) ) );
addInitializer( new Velocity( new DiscZone( Point3D.ZERO, Vector3D.AXISZ, 100 ) ) );
addInitializer( new Lifetime( 3 ) );

addAction( new Age( Quadratic.easeIn ) );
addAction( new Move() );
addAction( new Fade() );
//addAction( new Accelerate( new Vector3D( 0, -50, 0 ) ) );
addAction( new LinearDrag( 1 ) );
}
}

and for SphereBang:

public class SphereBang extends Emitter3D
{
public function SphereBang( position : Point3D, color : uint = 0xFFFF0000 )
{
counter = new Blast( 50 );

addInitializer( new ColorInit(color, color) );
addInitializer( new Position( new PointZone( position ) ) );
addInitializer( new Velocity( new SphereZone( Point3D.ZERO, 100 ) ) );
addInitializer( new Lifetime( 3 ) );

addAction( new Age( Quadratic.easeIn ) );
addAction( new Move() );
addAction( new Fade() );
//addAction( new Accelerate( new Vector3D( 0, -50, 0 ) ) );
addAction( new LinearDrag( 0.5 ) );
}
}

Here are the results I'm having:

I've tried to use more actions like Explosion and SpeedLimit without success.
There is any action I'm missing to help me or any parameter I should adjust?

Thanks in advance for the help.

Cheers,

The sphere and disc zones take an inner and outer radius. Try this addInitializer( new Velocity( new DiscZone( Point3D.ZERO, Vector3D.AXISZ, 100, 100 ) ) ); and this addInitializer( new ...

addInitializer( new Velocity( new DiscZone( Point3D.ZERO, Vector3D.AXISZ, 100, 100 ) ) );

and this

addInitializer( new Velocity( new SphereZone( Point3D.ZERO, 100, 100 ) ) );]]> http://flintparticles.org/forum/comments.php?DiscussionID=275&Focus=988#Comment_988 2009-11-25T04:16:01+00:00 2010-12-25T18:21:56+00:00 ptaranto http://flintparticles.org/forum/account.php?u=269

Thanks, that did the trick
