Hello, I saw a post from 2017 with this effect and would like to make something similar for my game, it’s pixel art top down, is there a way I can do this with the particle system only? thanks.
yes, you should look into particlesystem.emit.
in my opinion, this is the absolute best way to change particle systems dynamically.
Unity - Scripting API: ParticleSystem.Emit (unity3d.com)
That effect uses a setting called “Ringbuffer mode”. You can download the footsteps project from here: Particle System Ringbuffer demo
