[osg-users] particle speed in OSG Particle Effects

[Trajce Nikolov NICK]

Wops, too fast .. Pressed wrong keys

void osgParticle::ModularEmitter::emitParticles(double dt)
....
Particle* P = getParticleSystem()->createParticle(getUseDefaultTemplate()?
0: &getParticleTemplate());
            if (P)
            {
                _placer->place(P);
                P->setPosition(P->getPosition() * worldToPs);
                _shooter->shoot(P);
                P->setVelocity(osg::Matrix::transform3x3(P->getVelocity(),
                                                         worldToPs));

                if (cps)
P->setUpTexCoordsAsPartOfConnectedParticleSystem(cps);
            }
