Independent Particle Colors

[JJSax]

I'm trying to make a confetti particle system. My asset is just a white star and I'm wanting love2d to set the color per confetti star and hold that color throughout it's lifetime.

partycleSystem:setColors sets all particles to said colors/color pattern
and obviously setting the color right before drawing the particle system does the same.
I thought that setting the colors before emitting one would work but it again sets all particles to the same color.

How would I have one particle in the system stay one color?

You could use an atlas with several colored stars, then supply the quads with particleSystem:setQuads().

I could. I was just hoping to have the color be set by love2d. I'd prefer not to make whole new assets if I forget a color or something.

Sadly, so far I know there is no setColor function for particle systems. If the particle system is simple you could use a spritebatch instead.

Ah that's a shame. Then I have two options. Would it be more efficient to create a new particle system for every color I want or new sprites?

New sprites. The most expensive part, so far I know, is the draw call itself. Also keep in mind that if you use several systems, the colors are over each other, they don't mix.

Ok that works then. Thank you for your help!

I guess I don't know how to do this. I made a sprite batch, and got the quads. but particlesystem:setQuads(quads) treats it like an animation and iterates through them based off particle lifetime. (see .love attachment)

Why dont you just make a table that holds all the confetti particles, update all of them for things like movement of the confetti particles and then draw all of them using a SpriteBatch, setting thier individual colors with SpriteBatch:setColor( r, g, b, a )?

You mean something like creating a table of love.graphics.newParticleSystem()? Or do something outside of love2d's particle system entirely?
