Individual particles

Physics
#1

Is it possible to determine the individual particle velocities in a LiquidFun particle system? QueryRegion provides the locations but no more than that and it’s not possible to track the individual particles between queries.

#2

No? I’m just looking for a cheat/hack here…

Hi Matt,

At this time there’s no way to gather the velocity of individual particles in a region query. How crucial is this to your project? I can inquire with the engineers whether it’s possible to expose those properties during the query…

Take care,

Brent

Thanks Brent. It’s highly important but not breaking critical.

I’ve been thinking a lot about how to influence the path of particles and perform unusual jiggery pokery with them. For example, is it possible to apply a level of control to their movement. One example would be pushing them along a path or creating wind against them. The rectangular and non-rotatable query region is useful and, I imagine, highly performant, but it doesn’t provide much control or information.

I’ve tried using a physics body as a sensor to detect particle locations and velocities but sensors don’t generate collision events with particles.
