Is there currently a way to clone a particle? I've implemented my own quick and dirty solution using a helper class with a couple of static methods, but this has some speed implications, especially ...

Here's the code I'm using:

// creates a clone of the specified particle, attaches it to the emitter and then returns the new particle
public static function cloneParticle(emitter:Emitter, particle:Particle):Particle
{
var p2:Particle = emitter.particleFactory.createParticle();
emitter.addExistingParticles([p2], true);

mirrorParticle(particle, p2);

return p2;
}

// copies all of the properties of particle1 to particle2
public static function mirrorParticle(particle1:Particle, particle2:Particle, excludedProperties:Array = null):void
{
if (excludedProperties == null) excludedProperties = ["sortID", "image"];
else excludedProperties.push("sortID", "image");

var description:XML = describeType(particle2);

var varList:XMLList = description..variable;

for each (var item:XML in varList)
{
if (excludedProperties.indexOf(String(item.@name)) != -1) continue;

var prop:Object = particle1[item.@name];

if (prop is Number || prop is String || prop is Boolean) particle2[item.@name] = prop;
}
}]]> http://flintparticles.org/forum/comments.php?DiscussionID=156&Focus=631#Comment_631 2009-01-18T10:55:38+00:00 2010-12-25T19:38:17+00:00 Richard http://flintparticles.org/forum/account.php?u=1

Now you mention it, it seems so obvious. So I've added a clone method to the Particle class. This clones the image property along with everything else - if particles are used with a BitmapRenderer ...

Thanks for adding this Richard. The thing with the DisplayObjectRenderer image is a bit of a problem - they way I got around it was to let the emitter create the image when adding the particle. ...

if (image is IClonable) p.image = image.clone();
else p.image = image;

Obviously this may be a lot of work to implement...

Other than that, how would it be possible to create a copy of a DO image? I can't think of a neat way to do it that doesn't require knowledge of the parameters that were put into the emitter initialiser.]]> http://flintparticles.org/forum/comments.php?DiscussionID=156&Focus=636#Comment_636 2009-01-20T14:10:53+00:00 2009-01-20T14:12:18+00:00 Richard http://flintparticles.org/forum/account.php?u=1

Unfortunately, people use other display objects too - display objects created in flash for example - so it's not possible to expect a clone method for images, although it's theoretically possible ...

I did some very extensive tests to try to find a way to clone a display object, but even the ByteArray method doesn't work with display objects. So it seems there isn't a way, although it may be possible with reflection and a lot of code.]]>
