Parent particles to emitter

[Genebris]

Is therer a way to make particles move in emitter's local space? So when emitter moves, it's particles move with it, while still having their own speed?

While playing with the emitters in the editor I notice the following:

Velocity is local. So if you rotate the emitter, the particles are changing in direction.

Accelaration is global. No matter the rotation of the emitter, the particles do not change direction.

 

In the editor look for the checkbox: Rotate by velocity. By script:

SetRotationByVelocityMode(1)

But it doesn't help me. Velocity settings apply only on new particles. Particles that already was released won't change.

I guess I can just write particle system myself. Hope it won't be too bad for performance.

I don't think that the current particle system works like you want.

 

If I had a emitter simulating a valve where water is comming out of and I would increase the velocity, I wouldn't want the particles that have already spawned, getting that new velocity as well.

Yes, that's not realistic, but I'm making a a monster that has a black smoke instead of head and when he runs he leaves a long trail of particles behind instead of having thick smoke in place of head.

I'll make simple particles system myself and upload to workshop if it works.
