Getting 'env_smokestack' to fire?

Garry's Mod coding
#1

Hello Facepunch

I’ve been trying to create a smoke effect but sadly with no success, I’m unable to get the smoke to appear.

[LUA]
local smoke = ents.Create( “env_smokestack” )
smoke:SetPos(ent:GetPos())
smoke:Spawn( )
smoke:Activate()
smoke:Fire(“smoke”,"",0)
timer.Create(“timer2”,0.5,1,function()
smoke:Remove()
end)

[/LUA]

Your help with be greatly appreciated, thanks.

It has three inputs for turning on, off and toggle:
TurnOn TurnOff Toggle

So:


smoke:Fire("Toggle")

The valve developer wiki is your friend.
I didn’t even know env_smokestack was a thing

It looks like the problem is that even though the client constructor initialises its members to proper values, the server does not. This causes the server to network “0” for all of its keyfields that aren’t set, and thus causing no emission to happen. The workaround is to set all of the defaults manually serverside:


local smoke = ents.Create("env_smokestack")
smoke:SetSaveValue("InitialState", true) -- Not necessary, but do it to force a start

smoke:SetSaveValue("SpreadSpeed", 15)
smoke:SetSaveValue("Speed", 30)
smoke:SetSaveValue("StartSize", 10)
smoke:SetSaveValue("EndSize", 15)
smoke:SetSaveValue("Rate", 80)
smoke:SetSaveValue("JetLength", 180)
--smoke:SetSaveValue("m_bEmit", true)

smoke:SetSaveValue("BaseSpread", 20)

--smoke:SetSaveValue("Twist", 0)

smoke:SetPos(Entity(1):GetPos()) 
smoke:Spawn()
smoke:Activate()

Unfortunately, m_AmbientLight and m_DirLight still have incorrect values, but there’s seemingly nothing that can be done about that.
