This is what I did to make the particles start when the mouse goes down: import org.flintparticles.common.actions.Age; import org.flintparticles.common.actions.Fade; import ...

import org.flintparticles.common.actions.Age;
import org.flintparticles.common.actions.Fade;
import org.flintparticles.common.counters.Steady;
import org.flintparticles.common.displayObjects.Line;
import org.flintparticles.common.easing.Quadratic;
import org.flintparticles.common.initializers.ColorInit;
import org.flintparticles.common.initializers.Lifetime;
import org.flintparticles.common.initializers.SharedImage;
import org.flintparticles.twoD.actions.Accelerate;
import org.flintparticles.twoD.actions.LinearDrag;
import org.flintparticles.twoD.actions.Move;
import org.flintparticles.twoD.activities.RotateEmitter;
import org.flintparticles.twoD.emitters.Emitter2D;
import org.flintparticles.twoD.initializers.Velocity;
import org.flintparticles.twoD.renderers.BitmapRenderer;
import org.flintparticles.twoD.zones.DiscSectorZone;

var emitter:Emitter2D = new Emitter2D();

emitter.counter = new Steady( 200 );

emitter.addActivity( new RotateEmitter( -7 ) );

emitter.addInitializer( new SharedImage( new Line( 3 ) ) );
emitter.addInitializer( new ColorInit( 0xFFFFFF00, 0xFFFF6600 ) );
emitter.addInitializer( new Velocity( new DiscSectorZone( new Point( 0, 0 ), 250, 170, 0, 0.2 ) ) );
emitter.addInitializer( new Lifetime( 1.3 ) );

emitter.addAction( new Age( Quadratic.easeIn ) );
emitter.addAction( new Move() );
emitter.addAction( new Fade() );
emitter.addAction( new Accelerate( 0, 50 ) );
emitter.addAction( new LinearDrag( 0.5 ) );

var renderer:BitmapRenderer = new BitmapRenderer( new Rectangle( 0, 0, 500, 500 ) );
renderer.addFilter( new BlurFilter( 2, 2, 1 ) );
renderer.addFilter( new ColorMatrixFilter( [ 1,0,0,0,0,0,1,0,0,0,0,0,1,0,0,0,0,0,0.97,0 ] ) );
renderer.addEmitter( emitter );
addChild( renderer );

emitter.x = 260;
emitter.y = 350;
btn.addEventListener(MouseEvent.MOUSE_DOWN, emitter.start);

When I run the code I get this error:
1046: Type was not found or was not a compile-time constant: btn.
I don't see what I did wrong and I also don't know how to stop the emitter.]]> http://flintparticles.org/forum/comments.php?DiscussionID=481&Focus=1627#Comment_1627 2011-05-03T08:32:59+01:00 2011-12-11T10:08:05+00:00 Richard http://flintparticles.org/forum/account.php?u=1

It looks like btn isn't defined in your code.

What do you mean?

The error message indicates that btn (in the last line of your code) doesn't exist.
