Help with nocolliding ents produced by a loop

[Daggoth]

So I've pretty much fallen in love with the amazing WAC Little Bird Helicopter, and I decided to make my own variant for personal use with a number of exotic weapons. One of these was supposed to be a rocket swarm that would shoot 12 rockets all at once with slightly different trajectories to give them a bit of a spread. The only problem is that when I fire, all the rockets instantly explode and destroy the chopper. I think it's because they're being spawned at the same spot and they're colliding, but I don't know how to nocollide them all. Here's the relevant code snippet.

[lua]
[1]={
Name="Rocket Swarm",
Ammo=2,
MaxAmmo=2,
NextShoot=1,
LastShot=0,
ShootDelay=1,
Gun=1,
ShootPos={
[1]=Vector(50,70,-20),
[2]=Vector(50,-70,-20),
},
func=function(self,t,p)
if t.NextShoot<=CurTime() then
if t.Ammo>0 then
for shoot=0, 12, 1 do
local rocket=ents.Create("wac_hc_rocket")
rocket:SetPos(self:LocalToWorld(t.ShootPos[t.Gun]))
rocket:SetAngles(self:GetAngles()*Vector(0,0,math.random(0.9,1.1)))
rocket.Owner=p
rocket.Damage=150
rocket.Radius=200
rocket.Speed=60
rocket.TrailLength=100
rocket.Scale=7
rocket.SmokeDens=1
rocket.Launcher=self
rocket:Spawn()
rocket:StartRocket()
local ph=rocket:GetPhysicsObject()
if ph:IsValid() then
ph:SetVelocity(self:GetVelocity())
end
self.Sound.MissileShoot:Stop()
self.Sound.MissileShoot:Play()
constraint.NoCollide(self,rocket,0,0)
constraint.NoCollide(rocket,rocket,0,0)
t.Gun=(t.Gun==1 and 2 or 1)
t.LastShot=CurTime()
t.NextShoot=t.LastShot+t.ShootDelay
end
t.Ammo=t.Ammo-1
end
if t.Ammo<=0 then
t.Ammo=t.MaxAmmo
t.NextShoot=CurTime()+10
end
end
end,
},
[/lua]

I should also mention that I'm something of a novice lua coder, but I'm learning as best I can.

This is just going to spawn a bunch of rockets all at once. You need to do your spawning over a time period instead of just sticking it into a for loop. With this current spawning wether you have 1 or 12 there all going to the same area.

Here is how to no collide, it's pretty self explanitory.

and when debugging your stuff, lower the number down instead of using twelve you could start at one and move up slowly from there.

Okay. Is there a way I can put a delay in the loop the make the rockets fire sequentially?

Something kind of like this

[LUA]
local function FireRocket(current)

--Do rocket stuff here and fire one

current = current + 1
if(current>12)then return end
timer.Simple(0.5, FireRocket, current)--Set the timer for the next rocket
end

if t.NextShoot<=CurTime() and t.Ammo>0 then

local current = 1
timer.Simple(0.5, FireRocket, current)
end
