How to create a tracer from the gun?

[Worshipper]

Hi, I would like to create a simple tracer from the gun without shooting the bullet. I created a physical bullet that takes time to hit the target, but I can't seem to put a tracer that follows it.

For example, on a normal bullet function, they include a tracer in it. I would like to do the same thing and create a similar effect.

[lua]
local bullet = {}
bullet.Num = num_bullets
bullet.Src = self.Owner:GetShootPos() // Source
bullet.Dir = self.Owner:GetAimVector() // Dir of bullet
bullet.Spread = Vector(aimcone, aimcone, 0) // Aim Cone
bullet.Tracer = 1 // Show a tracer on every x bullets
bullet.TracerName = Tracer
bullet.Force = damage * 0.5 // Amount of force to give to phys objects
bullet.Damage = damage

self.Owner:FireBullets(bullet)
[/lua]

If anyone happens to know how it's done, please help me!

You can use this in the SWEP:Think

trace = self.Owner:GetEyeTrace()

Not sure though, might be a bit laggy

I want a tracer effect, not a simple eye trace.
Thanks anyway!

[lua] local effectdata = EffectData()
effectdata:SetOrigin( tr.HitPos )
effectdata:SetStart( self.Owner:GetShootPos() )
effectdata:SetAttachment( 1 )
effectdata:SetEntity( self.Weapon )
util.Effect( (tracer effect here), effectdata )[/lua]

Try This . For tracer effects look here : [url]http://wiki.garrysmod.com/?title=Util.Effect[/url]

But I have a little problem. If I want the same spread for the tracer (because I don't want a straight line), how am I supposed to match it?
Thanks for the help.

[lua]
/*---------------------------------------------------------
Shoot the dawn bullet!
---------------------------------------------------------*/
// Entity bullet made by Teta_Bonita

function SWEP:ShootBullet(dmg, speed, spread, spray, sprayvec, numbul, accel, mask, filter)

numbul = numbul or 1
accel = accel or Vector(0, 0, -600) // Gravity
mask = mask or MASK_SHOT // Tracemask

if (SERVER) then
for i = 1, numbul do
local eBullet = ents.Create("ent_op_bullet")

local Velocity = speed * (self.Owner:GetAimVector() + VectorRand() * spread + 0.04 * spray * sprayvec:GetNormalized()):GetNormalized()

eBullet:SetPos(self.Owner:GetShootPos())
eBullet:SetVar("Velocity", Velocity)
eBullet:SetVar("Acceleration", accel)

local tBullet = {} // This is the bullet our bullet SENT will be firing when it hits something. Everything except force and damage is determined by the bullet SENT
tBullet.Force = 0.15 * dmg
tBullet.Damage = dmg

local tTrace = {} // This is the trace the bullet SENT uses to see if it has hit something
tTrace.filter = filter or {self.Owner, eBullet}
tTrace.mask = mask

eBullet:SetVar("Bullet", tBullet)
eBullet:SetVar("Trace", tTrace)
eBullet:SetVar("Owner", self.Owner)
eBullet:SetVar("Weapon", self.Weapon)
eBullet:Spawn()

local tr = util.GetPlayerTrace(self.Owner)
local trace = util.TraceLine(tr)

local effectdata = EffectData()
effectdata:SetOrigin(trace.HitPos)
effectdata:SetStart(self.Owner:GetShootPos())
effectdata:SetAttachment(1)
effectdata:SetEntity(self.Weapon)
util.Effect("ToolTracer", effectdata)
end
end
end
[/lua]

Well, if it's an actual entity, not a point being iterated through space, then I would parent the effect to it. I know that another dynamic bullet system just did traces as fast as it could, which were serverside and therefore the clients' couldn't know where the bullet was and an effect could not be generated by it.
But yeah, I'd definitely try to tie the tracer to the bullet and not the gun, you know?

I found the way to make tracer , but it's bullet effect , gonna give you my code , wait

Maybe you should stop whining and be patient
