I'm working on a game with a plane and I try to use the particle system to generate a contrail of a plane when it boosts up.


this is my Class:

package particle {

import org.flintparticles.twoD.emitters.Emitter2D;
import org.flintparticles.twoD.actions.*;
import org.flintparticles.twoD.initializers.*;
import org.flintparticles.twoD.renderers.*;
import org.flintparticles.twoD.zones.*;
import org.flintparticles.common.actions.*;
import org.flintparticles.common.counters.*;
import org.flintparticles.common.initializers.*;
import org.flintparticles.common.displayObjects.*;
import org.flintparticles.twoD.activities.FollowDisplayObject;
import flash.geom.Point;
import flash.display.DisplayObject;

public class BoostEmitter extends Emitter2D {

public function BoostEmitter(plane, renderer) {

this.counter = new ZeroCounter();

this.addInitializer(new Lifetime(1,1));
this.addInitializer(new Position(new LineZone(new Point(0, 0), new Point(-200, 0))));
this.addInitializer(new ImageClass( Line, [10] ));

this.addAction(new RotateToDirection());
this.addAction(new Age());
this.addAction(new Move());
this.addAction(new Fade(0.8, 0));

this.addActivity(new FollowDisplayObject(plane, renderer));
}

public function startEffect() {
this.counter = new Steady(24);
}

public function stopEffect() {
this.counter = new ZeroCounter();
}
}
}

This is my extended emitter class.

And this my renderer:

private var renderer:DisplayObjectRenderer = new DisplayObjectRenderer();
private var boostemitter:BoostEmitter;

private function InitEmitter(plane) {
this.addChild(renderer);
boostemitter = new BoostEmitter(plane, renderer);
renderer.addEmitter(boostemitter);
boostemitter.start();
}

My problem right now:

The RotateToDirection() doesn't work. When my plane flies upwards in an angle of 40° the created particles will have an angle of 0° but they move in the 40° direction. ]]> http://flintparticles.org/forum/comments.php?DiscussionID=552&Focus=1928#Comment_1928 http://flintparticles.org/forum/comments.php?DiscussionID=552&Focus=1928#Comment_1928 Thu, 10 May 2012 04:51:18 +0100 iwdy24 iwc replica watches, for a classic look on the subject of piaget replica watches. ]]> http://flintparticles.org/forum/comments.php?DiscussionID=2&Focus=1927#Comment_1927 http://flintparticles.org/forum/comments.php?DiscussionID=2&Focus=1927#Comment_1927 Thu, 10 May 2012 04:50:37 +0100 iwdy24 patek replica watches are particularly produced to look like the originals, all of the chopard replica watches are crafted to meet the precise specifications of your original styles. ]]> http://flintparticles.org/forum/comments.php?DiscussionID=559&Focus=1926#Comment_1926 http://flintparticles.org/forum/comments.php?DiscussionID=559&Focus=1926#Comment_1926 Tue, 08 May 2012 08:25:36 +0100 evo
Here's the particle code:


if(_follow){
addActivity( new FollowDisplayObject(displayObject, _renderer, spreadX, spreadY));
}

counter = new Steady(10);

addInitializer( new Lifetime( .25, 1 ) );
addInitializer( new Velocity( new DiscSectorZone( new Point( 0, 0 ), 80, 60, degreesToRadians( 0), degreesToRadians( 359) ) ) );
if(!_follow){
addInitializer( new Position( new DiscZone( _location, 50 ) ) );
}
addInitializer( new SharedImages( [new Particle1(), new Particle2()]) );
addInitializer( new RotateVelocity(degreesToRadians( -200), degreesToRadians(200)));
addAction( new Rotate() );

addAction( new Age( ) );
addAction( new Move( ) );
addAction( new LinearDrag( 0.5 ) );
addAction( new ScaleImage( .5, 1 ) );
addAction( new Fade( 1, 0 ) );
addAction( new RandomDrift( 200, 200 ) );
addAction( new MutualGravity( 100, 200, 50 ) )

Looking at the code now, I believe it may be due to there being no Position set when using FollowDisplayObject. Just did a quick test though and it seems even when Position is set it still makes the first particle appear at 0,0.

I'll also include some slightly modified FollowDisplayObject code below. I made a small change but I don't believe it's causing the problem.


var e:Emitter2D = Emitter2D( emitter );
var p:Point = new Point( 0, 0 );
p = _displayObject.localToGlobal( p );
p = _renderer.globalToLocal( p );

if(_spreadX != 0){
p.x += Math.floor(Math.random()*(_spreadX))-_spreadX/2;
}
if(_spreadY != 0){
p.y += Math.floor(Math.random()*(_spreadY))-_spreadY/2;
}

e.x = p.x;
e.y = p.y;

I added some variables to create a particle spread around the displayObject and also removed the rotational code since it's not necessary for my application. ]]> http://flintparticles.org/forum/comments.php?DiscussionID=557&Focus=1925#Comment_1925 http://flintparticles.org/forum/comments.php?DiscussionID=557&Focus=1925#Comment_1925 Mon, 07 May 2012 14:23:25 +0100 bestam

from: forum.starling-framework.org/topic/direct-blit-for-gpu :--

"In Starling 1.1, there's the class "QuadBatch", which allows you to add quads to a GPU VertexBuffer quickly. The class was already in Starling 1.0, but I recently changed it to be easier to use: it's now a display object... rendering this object is super efficient. It's just one single draw operation, no matter how big the object."

Does this have the potential to clear the way for a more efficient implementation of Flint Particles with Starling? ]]> http://flintparticles.org/forum/comments.php?DiscussionID=563&Focus=1918#Comment_1918 http://flintparticles.org/forum/comments.php?DiscussionID=563&Focus=1918#Comment_1918 Mon, 23 Apr 2012 20:30:01 +0100 progressivity

First - thanks for such a great piece of work!
Ive got a little Problem with the actual version of Flint in work with away3d 3.6.0

http://dl.dropbox.com/u/10036823/prg2012.swf
You can zoom out by using the MouseWheel, and drag around the HoverCam.

The white cubies are the Particles from Flint, but there is just one little cube outside with properties i have given.

Here is the Code part:



package
{
import away3d.materials.ColorMaterial;
import away3d.primitives.Cube;
import org.flintparticles.common.counters.Blast;
import org.flintparticles.common.initializers.ChooseInitializer;

import org.flintparticles.threeD.initializers.Velocity;
import org.flintparticles.threeD.zones.BoxZone;
import org.flintparticles.threeD.zones.SphereZone;
import flash.display.DisplayObject;
import flash.geom.Vector3D;

public class particleField extends Emitter3D
{
public function particleField()
{
counter = new Blast( 50 );

addInitializer( new A3D3ObjectClass( Cube, [ { height:12, width:6, depth:6 } ] ) );
addInitializer( new A3D3ApplyMaterial( ColorMaterial, 0xFFFF00, 8 ) );
addInitializer( new Position( new BoxZone( 2000, 2000, 2000, new Vector3D( 0, 0, 0 ), new Vector3D( 0, 1, 0 ), new Vector3D( 0, 0, 1 ) ) ) );
addInitializer( new Velocity( new SphereZone( new Vector3D( 0, 0, 0 ), 15, 10 ) ) );

addAction( new Move() );
addAction( new Collide( 1 ) );
addAction( new BoundingBox( -1500, 1500, -1500, 1500, -1500, 1500, 1 ) );
}
}
}

Do you have any Idea why the other cubies wont join the properties ?

I need to simulate this water drops in Flex or AS3. The scenario is like that: User enters a letter, and click play. I will slide death zone that is shaped like that letter from top to bottom.

I've started with rain example but I couldn't find a way to slide death zone at the same velocity with the drops. ]]> http://flintparticles.org/forum/comments.php?DiscussionID=558&Focus=1914#Comment_1914 http://flintparticles.org/forum/comments.php?DiscussionID=558&Focus=1914#Comment_1914 Thu, 19 Apr 2012 22:48:20 +0100 Richard
From your brief description, what you're suggesting sounds very possible, yes.

That sounds strange. I don't recognise the particle effect you're describing. Flint is an Actionscript library, so can be used to create particle effects in Flash projects. So what you're seeing is a Flash movie. I don't know why it's displaying in every window of your computer. Sorry I can't help more. ]]> http://flintparticles.org/forum/comments.php?DiscussionID=555&Focus=1911#Comment_1911 http://flintparticles.org/forum/comments.php?DiscussionID=555&Focus=1911#Comment_1911 Thu, 19 Apr 2012 22:38:00 +0100 Richard
The C# version was started by a couple of other developers some time ago and never finished. My only involvement was helping them understand how Flint works. It's probably not in a good state to use. ]]> http://flintparticles.org/forum/comments.php?DiscussionID=553&Focus=1910#Comment_1910 http://flintparticles.org/forum/comments.php?DiscussionID=553&Focus=1910#Comment_1910 Thu, 19 Apr 2012 22:34:06 +0100 Richard
That's not implemented in the set of initializers included with Flint, but you could create a custom initializer to do it - it would be quite simple, similar to the Rotation initializer but with two more axes. ]]> http://flintparticles.org/forum/comments.php?DiscussionID=514&Focus=1909#Comment_1909 http://flintparticles.org/forum/comments.php?DiscussionID=514&Focus=1909#Comment_1909 Thu, 19 Apr 2012 22:32:15 +0100 Richard
It looks to me like you only create one particle - _p - at the start of the code, and then keep adding that same particle. If you want multiple particles, you need to create a new particle each time. Try

public function progress (value:int) : void {
var _p : Particle2D = new Particle2D();
_p.image = new Sparkle();
_emitter.addParticle(_p, true);
} ]]> http://flintparticles.org/forum/comments.php?DiscussionID=514&Focus=1908#Comment_1908 http://flintparticles.org/forum/comments.php?DiscussionID=514&Focus=1908#Comment_1908 Thu, 19 Apr 2012 16:01:28 +0100 George.M I am working on something quite similar, where I want to add more particles as something is charging up and more 'excitement' is displayed.


My main class contains:

public function initialize () : void {
_emitter = new Charge(); //

_p = new Particle2D();
_p.image = new Sparkle(); // a MovieClip
_emitter.addParticle(_p, true);


var renderer:DisplayObjectRenderer = new DisplayObjectRenderer();
renderer.addEmitter( _emitter );
addChild( renderer );

_emitter.start( );
}

public function progress (value:int) : void {
_emitter.addParticle(_p, true);
}



the emitter:

public class Charge extends Emitter2D
{
public function Charge()
{
counter = new ZeroCounter();

addInitializer( new Position( new RectangleZone( 10, 10, 680, 480 ) ) );
addInitializer( new Velocity( new DiscZone( new Point( 0, 0 ), 150, 100 ) ) );

addAction( new RotateToDirection() );
addAction( new BoundingBox( -25, 0, 770, 1200 ) );
addAction( new Move() );
}
}
}


Unfortunately no new particles are added, yet the one that does remain speeds up each time addParticle is called.
Swapping the counter for Blast(1) and adding in addInitializer( new ImageClass( Sparkle ) ); results in the effect I am looking for where there is a a new particle added.

But as more particles are added older ones freeze and fail to move any more.

Can anyone help? ]]> http://flintparticles.org/forum/comments.php?DiscussionID=553&Focus=1907#Comment_1907 http://flintparticles.org/forum/comments.php?DiscussionID=553&Focus=1907#Comment_1907 Tue, 17 Apr 2012 15:33:04 +0100 Antoine http://flintparticles.org/forum/comments.php?DiscussionID=553&Focus=1905#Comment_1905 http://flintparticles.org/forum/comments.php?DiscussionID=553&Focus=1905#Comment_1905 Mon, 16 Apr 2012 19:49:30 +0100 Richard emitter.addInitializer( new Rotation( 0, 2 * Math.PI ) );

Here's what I'm doing...

particle creation:
{
counter = new TimePeriod(30, .5);

addInitializer( new Lifetime( 3, 4 ) );
addInitializer( new Velocity( new DiscSectorZone( new Point( 0, 0 ), 250, 200, degreesToRadians( -230), degreesToRadians( -140) ) ) );
addInitializer( new SharedImage( new Dot( 5, 0xFF0000 ) ) );
addInitializer( new ScaleImageInit( .25, .55 ) );

addAction( new Age( ) );
addAction( new Move( ) );
addAction( new Accelerate( 0, 300 ) );

addAction( new CollisionZone( new RectangleZone( maxPos.x-1000, maxPos.y, maxPos.x + 2000, maxPos.y + 20 ) ) );

addEventListener(ParticleEvent.ZONE_COLLISION, doCollision);
addEventListener(EmitterEvent.COUNTER_COMPLETE, finishCounter);
}

docollision:
{
var p:Particle2D = Particle2D(e.particle);
p.isDead = true;
}

This code works fine for Blast/Steady counters but TimePeriod is causing the particles to simply bounce off of the collision box.

----------------------------------------------------------------------

Problem 2: The first particle of each new emitter is being created at location 0,0

This may be connected to using FollowDisplayObject but I'm not sure. It seems that with every emitter that I'm creating the first particle emitted is placed at coords 0,0 and animates normally. ]]> http://flintparticles.org/forum/comments.php?DiscussionID=558&Focus=1903#Comment_1903 http://flintparticles.org/forum/comments.php?DiscussionID=558&Focus=1903#Comment_1903 Wed, 04 Apr 2012 06:40:12 +0100 Astraport A very interesting library.

First post! Glad to be using FLiNT, looks to be the best flash particle engine out there. Exactly what I needed for my project, I will credit your work Richard.

However I'm having issues with larger particles. I'm emitting large smoke particles and smaller ones from the same point. As the particles aren't centered, I come up with this result :
http://www.itstudents.be/~abrakam/faeriawp/particles.png
I would like the big smoke to be occupying the same space as the smaller sparks... Is there a way to tell the emitter to center them all? Here is all I do to define their initial position :
locBigSmokeEmiter.addInitializer( new Position( new DiscZone( new Point( 0, 0 ), 30)));

Thx! ]]> http://flintparticles.org/forum/comments.php?DiscussionID=556&Focus=1900#Comment_1900 http://flintparticles.org/forum/comments.php?DiscussionID=556&Focus=1900#Comment_1900 Fri, 30 Mar 2012 02:20:46 +0100 Arctem http://flintparticles.org/forum/comments.php?DiscussionID=556&Focus=1899#Comment_1899 http://flintparticles.org/forum/comments.php?DiscussionID=556&Focus=1899#Comment_1899 Fri, 30 Mar 2012 00:25:08 +0100 Arctem http://flintparticles.org/forum/comments.php?DiscussionID=556&Focus=1898#Comment_1898 http://flintparticles.org/forum/comments.php?DiscussionID=556&Focus=1898#Comment_1898 Fri, 30 Mar 2012 00:20:35 +0100 Arctem http://flintparticles.org/forum/comments.php?DiscussionID=555&Focus=1897#Comment_1897 http://flintparticles.org/forum/comments.php?DiscussionID=555&Focus=1897#Comment_1897 Tue, 27 Mar 2012 09:56:41 +0100 smtabatabaie thanks ]]> http://flintparticles.org/forum/comments.php?DiscussionID=553&Focus=1896#Comment_1896 http://flintparticles.org/forum/comments.php?DiscussionID=553&Focus=1896#Comment_1896 Mon, 26 Mar 2012 02:43:01 +0100 czyky
