Change particle velocity

Questions & Answers
1

I was wondering if you can change the velocity of particle that have been already created.

I tried changing the emitters world velocity but that doesn't seem to look right.

emitter.worldVelocity = Vector3.down * gameSpeed;

Can you effect already created particles?

I think what your looking for is the particle emitter's. local velocity along with particle animator's. damping and force per frame

Take a look at ParticleEmitter.particles and of course Particle itself.
