paticles appear at speed?

I want to have particles appear over a certain speed

i have the particle script - usual one

but when i say move faster then say 3 m/s the particle triggers then when i stop or slow below that the particles stop



so the script has to detect velocity and know how fast it is going to do this maybe with a timer event

Try this:


list ParticleParams = [] //Put your particle data in this list

default
{
state_entry()
{
llSetTimerEvent(1.0);
}

timer()
{
if (llVecMag(llGetVel()) > 3.0)
{
llParticleSystem(ParticleParams)
}
else
{
llParticleSystem([]);
}
}
}
