Particles with collision jitter.

Unity Engine
1

Hi,

I have some particles that collide with other objects but when they slow down, they jitter, I want them to get completely stop when their speed is zero.

Thanks.

Hey there,
I had the same problem, first occured to me in U2018. No solution, but at least a quick and dirty workaround is to use “Limit Velocity over Lifetime” with dampening 1 and key the curve sharply to zero the moment the particles collide. Note that the particles won’t budge now, not even be affected by gravity, which might not be what you want. I’ll let you know if I find a better solution.

Hi,

apparently the gravity modifier is causing the jitter. If you still want to use gravity, I recommend using a curve that hits 0 at the end. 8552567--1143533--upload_2022-10-31_17-23-56.png This works like a charm for me and it completely stops the stutter.

You’re replying to a post from 2019!

I’ll move the thread to General Graphics, the particle system isn’t a 2D feature anyway.

I know, but I stumbled upon it via google, so I figured I’ll share my quick fix for anyone that might be stumbling across it in the future ^^
