I cannot find any answer on how to access Velocity over Lifetime in the Shuriken Particle System documentation or in Answers. Mostly, people share the approach of accessing each individual particle.
Is there a way to access the Velocity over Lifetime vector in C#?
Sorry to be the bearer of bad news, but if it’s not in the API, you can’t access it via scripting. Like other people said, you could query existing particles, but that property isn’t exposed in scripting. Maybe you could try using reflection to find it, but a quick glance over the UnityEngine.dll suggests that it does all those calculations through external calls…
