Pew Pew sound emitting

[Rayler]

Cheers!

i want to add thruster sound to my "Pew Pew" weapon.
The sound is working but i can't stop it, and the sound continue emitting, when the rocket explode.
The sound only stopping when i shoot new rocket.

-- Think
BULLET.ThinkOverride = true
function BULLET:ThinkFunc( self )
-- Make it fly
self.Entity:SetPos( self.Entity:GetPos() + self.FlightDirection * self.Bullet.Speed )
if (self.TargetPos != Vector(0,0,0)) then
self.FlightDirection = self.FlightDirection + (self.TargetDir-self.FlightDirection) / 20
self.FlightDirection = self.FlightDirection:GetNormalized()
end
if (self.Cannon:IsValid()) then
if (self.Cannon.TargetPos and self.Cannon.TargetPos != Vector(0,0,0)) then
self.TargetDir = (self.Cannon.TargetPos-self:GetPos()):GetNormalized()
end
end
self.Entity:SetAngles( self.FlightDirection:Angle() + Angle(90,0,0) )

self.SoundName = Sound( "thrusters/hover01.wav" )

if (self.Cannon:IsValid()) then
self:EmitSound( self.SoundName )
else
self:StopSound( self.SoundName )
end

[/lua]

Sorry im new in lua, yesterday started learning.

Thanks Divran!:)
You mean something like this?
I Don't understand how can i link back to the function.

[lua]
function Sound()
self.SoundName = Sound( "thrusters/hover01.wav" )
self:EmitSound( self.SoundName )
end

function ENT:OnRemove()
self:StopSound( self.SoundName )
end
[/lua]

[Divran]

You should use a sound that loops by itself, and create it in the initialize function and stop it in the explode function.

[Rayler]

I know, i have to learn more about lua, but i think the best way when we use "more complex" lua's.
So, any idea how can i use this function in this homing missle?
When i create this sound in the initialize the sound work, and sound stop doesn't work while it's exploding, so same problem.

You haven't changed anything in the think function, no need to override it.
Your bullet won't explode now, because you've overwritten the explode function with a function that only stops the sound.

[Rayler]

Dont know what can i do now.
I tried 100 version, but now when i use:

local SoundName = Sound( "thrusters/hover01.wav" )
or
self.SoundName = Sound( "thrusters/hover01.wav" )

i get error message: stack overflow :(

[Divran]

I already gave you a fully working code (untested, sure, but it should work just fine), you just failed to use it correctly (Although how someone can fail to copy paste a code correctly beats me).
Don't know what more I can do.

You're still not doing it correctly. But if it works..

[Rayler]

I said, yesterday started to "learn" lua, so i need more time to understand.
So we can't do this with emitsound? Because the CreateSound don't have amplifier.
Any idea how can i make this sound more louder?
