How does util.ParticleTracer work?

There's no page for it on the wiki, but it's a command.

I'm guessing it makes a tracer using the particle system, but I have no idea how to use it.

This is how you use it:

util.ParticleTracer(strName, vecStart, vecEnd, boolWhizz)

I think the parameters are self-explaining. (Except for boolWhizz, no idea what that is for.)

There's also a similar function called "util.ParticleTracer.Ex", but that never really worked for me:

util.ParticleTracerEx(strName, vecStart, vecEnd, boolWhizz, int iEntity, int iAttachment)

An alternate way would be to create a [URL=http://developer.valvesoftware.com/wiki/Info_particle_system]info_particle_system[/URL] entity and set the keyvalues manually. That's what I'd do.

Yeah but info_particle_systems are painful to assign control points with, so I'll give it a shot.

Well I hooked it up like this.

	local bullet = {}
	bullet.Num 		= numbullets
	bullet.Src 		= self.Owner:GetShootPos()			
	bullet.Dir 		= self.Owner:GetAimVector()			
	bullet.Spread 	= Vector( scale, scale, 0 )		
	bullet.Tracer	= 1	
	bullet.Force	= math.Round(damage * 1.1)							
	bullet.Damage	= math.Round(damage)
	bullet.AmmoType = "Pistol"
	bullet.TracerName 	= "Tracer"
	bullet.Callback = function ( attacker, tr, dmginfo )
	util.ParticleTracer( tracer_du, self.Owner:GetShootPos(), tr.HitPos, true )
end

And it's making the tracer(yay!) but it's coming from the origin.
It's hitting the target, but not coming from my gunbarrel.

I think that if it is true and the trace went near a player, a "WHIZZ" sound is played for that player.

Yes, whenever an individual particle moves near a player they get a whizz noise.
