Making an SWEP play music

[quigon]

Hello there, I really need some help with coding my first SWEP. I followed the instructions on the gmod wiki for the "Chair gun" but found myself wanting to make the gun play some music when pressing the shoot button like the nyan cat gun.

This is my script so far:

SWEP.PrintName			= "Turtle Gun"			
SWEP.Author			= "( QuiGon)"
SWEP.Instructions		= "Left Click To Shoot Freaking TURTLES!"
SWEP.Spawnable = true
SWEP.AdminOnly = false
SWEP.Primary.ClipSize		= -1
SWEP.Primary.DefaultClip	= -1
SWEP.Primary.Automatic		= true
SWEP.Primary.Ammo		= "none"

SWEP.Secondary.ClipSize		= -1
SWEP.Secondary.DefaultClip	= -1
SWEP.Secondary.Automatic	= false
SWEP.Secondary.Ammo		= "none"
SWEP.Weight			= 5
SWEP.AutoSwitchTo		= false
SWEP.AutoSwitchFrom		= false

SWEP.Slot			= 1
SWEP.SlotPos			= 2
SWEP.DrawAmmo			= false
SWEP.DrawCrosshair		= true
SWEP.ViewModel			= "models/weapons/v_smg1.mdl"
SWEP.WorldModel			= "models/weapons/w_smg1.mdl"
local ShootSound = Sound( "Metal.SawbladeStick" )
--
-- Called when the left mouse button is pressed
--
function SWEP:PrimaryAttack()

	-- This weapon is 'automatic'. This function call below defines
	-- the rate of fire. Here we set it to shoot every 0.5 seconds.
	self.Weapon:SetNextPrimaryFire( CurTime() + 0.1 )	

	-- Call 'ThrowChair' on self with this model
	self:ThrowTurtle( "models/props/de_tides/vending_turtle.mdl" )

  self.LoopSound = CreateSound( self.Owner, Sound( "weapons/Turtle.mp3" ) )
            if ( self.LoopSound ) then self.LoopSound:Play() end
        


end
 

--
-- Called when the rightmouse button is pressed
--
function SWEP:SecondaryAttack()

	-- Note we don't call SetNextSecondaryFire here because it's not
	-- automatic and so we let them fire as fast as they can click.	

	-- Call 'ThrowChair' on self with this model
	self:ThrowTurtle( "models/props/de_tides/vending_turtle.mdl" )

end

--
-- A custom function we added. When you call this the player will fire a chair!
--
function SWEP:ThrowTurtle( model_file )

	-- 
	-- Play the shoot sound we precached earlier!
	--
	--
	-- If we're the client ) then this is as much as we want to do.
	-- We play the sound above on the client due to prediction.
	-- ( if ( we didn't they would feel a ping delay during multiplayer )
	--
	if ( CLIENT ) then return end

	--
	-- Create a prop_physics entity
	--
	local ent = ents.Create( "prop_physics" )

	--
	-- Always make sure that created entities are actually created!
	--
	if (  !IsValid( ent ) ) then return end

	--
	-- Set the entity's model to the passed in model
	--
	ent:SetModel( model_file )
 
	--
	-- Set the position to the player's eye position plus 16 units forward.
	-- Set the angles to the player'e eye angles. Then spawn it.
	--
	ent:SetPos( self.Owner:EyePos() + ( self.Owner:GetAimVector() * 16 ) )
	ent:SetAngles( self.Owner:EyeAngles() )
	ent:Spawn()
 

	--
	-- Now get the physics object. Whenever we get a physics object
	-- we need to test to make sure its valid before using it.
	-- If it isn't ) then we'll remove the entity.
	--
	local phys = ent:GetPhysicsObject()
	if (  !IsValid( phys ) ) then ent:Remove() return end
 
 
	--
	-- Now we apply the force - so the chair actually throws instead 
	-- of just falling to the ground. You can play with this value here
	-- to adjust how fast we throw it.
	--
	local velocity = self.Owner:GetAimVector()
	velocity = velocity * 1000
	velocity = velocity + ( VectorRand() * 50 ) -- a random element
	phys:ApplyForceCenter( velocity )
 
	--
	-- Assuming we're playing in Sandbox mode we want to add this
	-- entity to the cleanup and undo lists. This is done like so.
	--
	cleanup.Add( self.Owner, "props", ent )
 
	undo.Create( "Thrown_Chair" )
		undo.AddEntity( ent )
		undo.SetPlayer( self.Owner )
	undo.Finish()
end

Yes I left in the comments but I was too lazy to take 'em out :P.

What code do I enter for it to play music? And also I don't know where to put specific code so if you could include that in your post that'd be awesome!

If you are trying to make it play music like with the nyancat gun, two things, one is to make it auto-download the music so it works plays music instead of giving errors, two is you need to loop it with the gun fire like with the nyan cat gun, you can always check the script for the nyan cat gun for help :)

Thanks, but i don't know how to loop it or what code from the nyan gun to put into my script..... i just started learning lua today lol. I guess i should've mentioned that in the first post. 0_o

How do you learn without trying? Read the SWEP:PrimaryAttack() function in the post above and basically copy it and put in your file name for the loop.
