Hey, and may I ask what the best approach to achieving the same using TypeScript would be? I have been trying to bind the update function to the ParticleSystem class, so that I could access internal variables in the function (like _scaledColorStep), but I have so far been unable to access the parameter (this or otherwise).
The other two “customs” are quick, too, so don’t put a quadrillion lines of for/next loop in any of them, or you will bog into the local swamps, perf-wise. Keep in mind that the updater func runs very fast and continuous. CPU particles have some advantages over GPU. Put those 3 custom funcs into YOUR PS code… and take the 3 installer lines (85-87), too. It might be useful to learn the properties on a particle base-class object.Īnd the custom startPosition function… might also be hack-able.

Hell also shows how to make the snow stick to other layers in your composition.
You could change that… right there… perhaps make the particles do as you please. Jerzy Drozda Jr (aka Maltaannon) demonstrates how to generate snow using Particle Playground in After Effects. Up in lines 40-45… in the custom updater func… you can see some mention of particle age and recycling. In lines 85-87, you can see the three “custom functions” get installed in the particleSystem (thx to deltakosh for making these easy function-over-ride properties).

In other words, the BJS lib uses the very same code by default. I THINK they are currently shown… in un-modified state. When customizing the Particle Playground effect, the. In lines 18-58… are 3 functions… one for startPosition, one for startDirection, and one for updating. When we use the term layers in after effects,we are referring to the layers on the layer panel. I just activated the correct type of PS for his idea to …if you are willing to STAY in CPU-particles-land, then you MIGHT have some more power over recycled particles. But… there is stuff to ponder… about max capacity and particle ages/recycling. Move forward one keyframe and set that particles per second to 0. Go to the start of your timeline and turn the particles per second WAY up, now keyframe that value. Most times, I just “blow off” max particleSystem capacity… setting it to any big number and moving-on with my bad coding. Make a really large emitter, large enough to fill your screen. (no promises) After that discussion with Deltakosh about emitRate… I realized I don’t yet understand it, and have assumed that I did. Read that reasonably-short conversation between Deltakosh and I, and maybe it will hold some answers. Then you may want to change other parameters too, like longevity for example. I am aging the particles to death… faster than the climb to saturation.īut that’s not the way it works. Change the effect settings instead: go into physics and change velocity and gravity to something really small. maxLifetime, so in my thinking, the particleSystem cannot ever “saturate” (reach max particles). Deltakosh tried to pull my head out of my butt… during a conversation that started here. I wanted the yellow box to remain easily-visible thru the particle spray, even after 10 minutes (consistent emit rate) but… there’s stuff I didn’t understand. Just a note… I struggled with this situation, too.
