I've experimented with the Visionaire particle system quite a bit now. I've also watched several videos/tutorials about particles in general. How they work, what the attributes do and so on. Sadly I just experimented with the particles in my pixel art game; so in a very low resolution. I've managed to make a decent steam/smoke cloud coming of a pan but I'm not that happy with my electric sparks (literarily just pixels which "squirt" out of a cable).
My questions relay on the particle images. How exactly do they work? When I load a 16x16 pixel particle image of a heart, should the particles look like that specific heart? Does it work with transparent images? And how would a particle image of rain look like? Is it just one small line representing one rain drop or can I make a bigger image with many smaller and bigger lines?
P.S. I could share my two particle systems. if anyone is interested, leafe a comment. ;-)
