Sooo... I was doodling around in pico-8, creating a game for #1GAM, and I needed to create some particle systems, so I started to code one, but carried away a bit, and made a general purpose particle system library... and then carried away a bit more, and made a couple of samples for it, and took the liberty to call it "advanced" :) and here is the end result. :)
Feel free to use it in your projects if you want!
A couple of remarks though:
- I don't know a lot about lua optimalizations, but I guess it is not really optimized for speed. :)
- It is quite big in its current form. I guess. This sample cartridge is hovering on the limits of code size, but the library part is way smaller, and more importantly, quite modular. I plan to look into minifying the code, if there are any interest.
- I don't even know if a "library" is viable concept in pico-8... The size limitations are quite severe, so you only want to include what you absolutely must in your code, which usually means hand-coding everything.
- Ohh, and it is quite possible contains bugs. Use at your own risk. :)
- There are documentation or explanation of the workings of any kind for now, but I will write some later. Just look at the code till then. :)


Hi! First post and just bought Pico8 :) I think I'm missing something, but... How do I access the source code of this? Thank you!


pistacchio:
- download the cart (right-click on the magenta cart name in the first post and save the .p8.png somewhere, that file is the actual cartridge containing code, gfx, music etc...)
- put it in your pico-8 homefolder
- load it from within pico-8 with load ("load 10440" in this case)
Cheers!

Well, Connor, you could get rid of things you didn't want.
For example, the only thing I'd probably need is the explosion and the sparks.


changed line 580 from
local e = psystem.emitters[flr(rnd(count(psystem.emiters)))+1] |
to
local e = psystem.emitters[flr(rnd(#(psystem.emitters)))+1] |


Hey thanks for fixing it. :)
This is pretty awesome. My favorite is the blood effect.


I use the library in my Jam game and it worked great for explosions. The second cart in the thread is the one to download.


Use the last cart you see in the thread, it works. I've used it on a few games thus far and it works great. Only suggestion would be to strip out anything you don't need. As-is, it's pretty fat but you can dig through and see which functions are not needed and remove them.
