How can I make random particle flow like this? (includes example gif Construct 2)

I know how I would create particles which appear with a random size and scale them down in size dynamically over time or via distance calculation, but
how can I create such a particle flow that randomly follows a given path(or make it easily look like that)?
All good ideas and nifty solutions are welcome :).

◄ This random particle flow was created with Construct 2.

It's so easy!
Object A - if alterable value z = 0: create Object B, Object B:set xpos to xpos+(Random(20)-Random(20), Object B: set alertable value a to random(8), Object A:set alterable value z to 1, Object A:destroy.;
if Alterable value a of Object B = 1: follow the first flow.
same to the all 7 flows.

GamerH2,could you make a example?

I was going to do some animated bubbles for Spryke's underwater levels in the next week or two anyway. So when I saw your post, I figured I may as well do them today and share them with you. Feel free to use this in your game if you like it.

The code isn't the cleanest, and is probably overcomplicated. And the movement still isn't quite right. But I've commented it, so you should be able to customise and modify it to your liking. Just modify the various alterable values in the "setup" group. And of course you can replace the bubble graphics with whatever you like

Thank you very much for sharing your ideas, Volnaiskra! I think this example is a good base for all sorts of particles.
I already have some good ideas for optimization and additional features. Thanks.

Great example!! When you optimize it, can you please post the mfa? It would be useful for a lot of us. Thank you. :)

Thank you Volnaiskra,once again you've been a big help to the clickteam community.:)

Thanks guys :)

I added the bubbles into Spryke today, and added some nice player interaction to them.

Here's the additional code I used:

When Spryke collides with a bubble, a portion of Spryke's X speed gets transferred to the bubble continually (and eventually peters out back to zero when Spryke no longer overlapping it).

Also, when Spryke collides with a bubble, it can 'split' into smaller bubbles. It does this by shrinking the bubble, and spawning 3 new child bubbles near it. The new bubbles are created in the "create extra bubble" fast loop, which is basically identical to the original bubble spawning fast loop, but with a few variables changed (to ensure the new bubbles are small, already visible, already rising fast, and also inherit some of Spryke's X speed).

To prevent performance grinding to a halt, this 'splitting' mechanism only happens 40% of the time, never more than once per bubble, and never at all with the child bubbles.

Looks beautiful!!!

Very cool interaction with the environment, Volnaiskra!
How do you actually create the extra bubbles? What happens On loop?
You said it's basically identical to the original bubble spawning fast loop, but I couldn't find any fast loops in your mfa example.

That looks really nice and professional.

Volnaiskra, that is amazing. Thank you for sharing, though I couldn't replicate it with the added code you posted.

Oh, I just meant line #5 (the first real line of code). I forgot that I put it inside a fastloop after I posted the MFA (The only reason I had to put it in a fastloop was to make it easier for me to get the bubbles to start from 3 different locations)

The new fastloop looks like this, and is similar to line #5 in the MFA, but with values such as age, alpha, XYposition and gravity tweaked

I also disabled the magnetism mechanic (I set the bubbleAge to 301, which overrides line #32, and I manually inactivated line #34)

The whole thing could certainly do with some optimisation (The bubble uses all 26 of its alterable value slots!), but it works well enough for now.
