Particle Systems Help : )

I need halp on making a nice looking particle effect for and explosion are their any good tech notes or examples i could have a look at :) it would be much appretiated :D

just draw some dots on frame one then scale them up onf frame 10
then add a shape tweening an waila got yourself an easy explosion effect
wouldnt that be easier :)

Agreed alot easier :) but i just want to try my luck at Action Scripted particle explosion's :D i have made a few particle explosions already but i want to know how everyone else goes about doing them :)

BTW the 2 particle effets i am looking for are

1/ A fire works explosion effect where the particles exploade out circular.

2/A fountian type particle effect.

:D

have a look at;
http://www.robertpenner.com/
he's got a few particle effects there.

Thanks Blink thats the site i lost from my favorites , :)

Any other refrences would be appretiated :) More looking for the 2 different partile effects and how other people have made them

Just made an example of the fountian particle effect. This is what i want but i want gravity :)

click here

took 5 min

my version doesn't consist of any gravity/velocity :) its just a mathmatical tween

once made a fairly poor particle explosion effect...

Nah thats not bad actually :)

lost the fla but ive basicly re-witten it in another thread

This is what I do. I have 2 mcs.

Emitter
This baby is nothing but an empty clip with a controller inside it. The controller's _visible is set = false onClipEvent(load), and all it does it duplicate Particles to its _parent and assigns them random (based on minimum and maximum values) initial velocities, scales and rotation.

Particle
This contains the graphic, and yet another controller with _visible set to false. This controller takes the values it has been assigned, and turns them in an X velocity, a Y velocity and whatever else you could want. On every enter frame it changes its _parent's _x and _y based on the velocities, and also adds gravity on to the Y velocity. When the particle hits a point, it puts itself back to the start of the system, or removes itself (this is up to you, i use both in different situations)


Just try it. Forget what other people say. Once you have a solid particle system programmed, you'll be able to get exactly what you want just through some experiemenation.

Yeah thats like what i did but for the motion i used a easing formula instead of gravity and velocity ,(cause i dont know how to implement the properly code wise :) ) i used to make a container clip to but i found it easier to make a function on the timeleine instead :)

on the time line i put the following

function dup(){
max = 20;
for(i=1; i<=max; i++){
_root.part.duplicateMovieClip("part"+i,i);
}
}

dup();

and on the autuall particle movie clip i put the random easing this give a nice effect but i want to use gravity and have the particles fall and move according to gravity and velocity.

Do you have any fla files i can browse through for the gravity :)

example of mine is here if u havent already seen it

click here

Hehe just looking at my one then , remind me of the blood effect when u kill someone in the game Vandal Hearts :P

Last night I decided to learn about Object.registerClass and I came up with a particle system subclass, which isn't quite done, but maybe you'd be interested in seeing it when it is. Don't be put off by the object stuff. You'll understand the code immediately, its very simple.

circular explosion - this is probably done the same same way as most: http://www.happylander.com/tests/monitorbash.htm

fountain:

http://www.happylander.com/tests/winebottle.htm

Here's my little fountain... you can dag it, and it spins when the mouse is above or below it. To make it into an explosion, make the setting of o and a in the new particles more random (ie from *-1.5 to *1.5)

Here's the file... duh/me

Thanks guys thats great :)

sorry i didnt reply sooner i was in sydney for a week :)

I also have some basic fountains here:
http://userpages.umbc.edu/~tmccau1/flash/fountains.swf

I dont think I have the fla online but I can post it if anyone wants it (when I get home ;))

That look awsome :) if you do find the fla i would love to take a look at it :cool:

ok heres my fountains fla :)

Thanks for that but theirs one problem :)

when i play the movie the whole thing shrinks till you cant see it and does nothing :)

Ah, no doubt because I made it back before MX so the prototypes dont have the this prefix, and since they are in _root, they will all reference _root in MX and ultimately shrink the screen lol. I can go through and fix that. Ill post it when I do heh

fixed :) (whutta pain, I have so many files that are like this too lol)

hey senocular, your fountain .fla is exactly what i've been wanting to explore - thx fella. :)
