Hi, I´ve tried several ways to iterate through the array but I can´t get it to work.
Here´s the code were it updates Particles:
function updateParticles():void {
var particle:Particle;

// if there are more than 500 particles delete the first one in the array…
while (particles.length>500) {
particle=particles.shift();

particle.disable();

if (! spareParticles[particle.spriteClass]) {
spareParticles[particle.spriteClass] = new Array();
}

spareParticles[particle.spriteClass].push(particle);
}

// go through the array of particles…
for (var i:int = 0; i //… and update each one
particle=particles[i];
particle.update();
if (particle.clip.width<2) {
particle.disable();
}
}
}

How should I do?

Hi Danne, I don’t have the exact code in front of me but I suspect you just need to iterate through each particle in the array and removeChild on each one. Or just find the bit of code that deletes one particle and do it on all of them!

Sorry I mixed up the particles and the Papervision tutorials!

Now I got a question. How do I delete all the particles on a mouseout?
Is there a remove_all version in AS3?
I have made a remove EventListener and it works
but there remain frozenparticles on stage when I do this.

I thought it had to be complied in Flex to work!
Sorry!

Hi Danne, it’s just AS3 code now, so I’m not sure what you’re asking!

Is it possible to convert the Flexcode to common AS3 code?
Could use some hints to this!
Thanks for the lecture your are a great entertainer!
Had a lot of fun!

Hi Hector,

Of course you can use my code as you wish, I’d be really keen to see what you do with it so let me know, and good luck!
