gmsv_pvs allows you to master player-entity networking
You can have full control on what entities the client will see and hear

Functions / Variables

PVS_CONNECTED -- Just a random number, set to 26 from module.
pvsSetUpdateTime(seconds) -- Set the update time for the pvs. Defaults to 1 second
Player:UpdatePVS() -- Force a pvs update to a player

hook.Add("SameInstance", "SameInstanceCheck", function(ply, ent)
    return bool -- true for ents to see each other, false to disallow them to see each other
end)

Example

require("pvs")

-- Lets make sure all clients have time to actually recognise the player
hook.Add("PlayerInitialSpawn", "PVSPlayerInitialSpawn", function(ply)
	ply:SetColor(255, 255, 255, 0)
	timer.Simple(5, function(ply) -- 5 seconds should be fine
		if(IsValid(ply)) then
			-- print("SetElasticity")
			ply:SetColor(255, 255, 255, 255)
			ply:SetElasticity(PVS_CONNECTED) -- Once this is set SameInstance will be called for the player
		end
	end, ply)
end)

-- Force update pvs for a player
concommand.Add("pvs_update", function(ply)
	ply:UpdatePVS()
end)

concommand.Add("pvs_setupdate", function(ply, cmd, args)
	pvsSetUpdateTime(tonumber(args[1]))
end)

local Owner, Parent
hook.Add("SameInstance", "SameInstanceCheck", function(ply, ent)
	-- print(ply, ent)
	
	Owner = ent:GetOwner()
	if(IsValid(Owner)) then
		if(Owner == ply) then
			return true
		elseif(Owner:IsPlayer()) then
			return false
		end
	end
	
	Parent = ent:GetParent()
	if(IsValid(Parent)) then
		if(Parent == ply) then
			return true
		elseif(Parent:IsPlayer()) then
			return false
		end
	end
	
	return !ent:IsPlayer()
end)

Notes

The variable PVS_CONNECTED is used in a PlayerInitialSpawn hook.
You must Player:SetElasticity(PVS_CONNECTED) to allow SameInstance hook checks to run for the player, otherwise a player may completely not exist for certain clients.

How it Works

The module hooks onto the engine functions "CheckTransmit" and "EmitSound"

CheckTransmit is ran every time a player's pvs is updated and when the server should send the client what it should see / what it should know exists.
Every time CheckTransmit is ran it will check if it's time to update. If it's time to update it will run the given players ents within it's pvs through the SameInstance hook. After all the entities are ran through the hook the info is saved into a variable so if CheckTransmit is ran again before another update time it will use that last variable.

EmitSound will use that variable to determine what a client should hear.

Glad you decided to release it. Will be very useful !

[Mr_Roberto]

haha you are on a roll spacetech

[Drew P. Richard]

I'm sorry for bumping this thread, I PM'ed Spacetech and he said he won't be able to work on it for a while, and told me to try asking here. Basically, whenever I try using this module it is crashing the server. I think it may have to do with one of the new updates. I was wondering if anyone could try to fix it?

Does it crash instantly? Do you have any mdmp files?

[Drew P. Richard]

It crashes on when a player joins. Let me make it happen again and upload some crash dumps.

Code I am using:

//PVS TEST

MsgN("LOADING PVS!")
require("pvs")
 
-- Lets make sure all clients have time to actually recognise the player
hook.Add("PlayerInitialSpawn", "PVSPlayerInitialSpawn", function(ply)
    ply:SetColor(255, 255, 255, 0)
    timer.Simple(5, function(ply) -- 5 seconds should be fine
        if(IsValid(ply)) then
           print("SetElasticity Test")
            ply:SetColor(255, 255, 255, 255)
            ply:SetElasticity(PVS_CONNECTED) -- Once this is set SameInstance will be called for the player
        end
    end, ply)
end)

hook.Add("SameInstance","SameInstanceCheck",function(ply,ent)
    print(ply, ent);
	return true;
end)

It seems to call SameInstance just once before it crashes.

[thejjokerr]

Could this module be used to stop people from getting the 'Reliable Snapshot Overflow' kick?

[DarKSunrise]

Does anyone have a working version of this module? It crashes me instantly. Here's a link to the dump, and the results from dumps.garrysmod.com. Below is the code that I used.

function GM:SameInstance(ply, ent)
	print("GM:SameInstance(", ply, ent, ")");
	
	return true;
end

[Mr.Thorn]

Yeah same, anyone? Any fix?

[Spacetech]

Mr.Thorn posted:

Me and voided looked into it, both of us can't figure out why it crashes.

[Mr.Thorn]

So no update coming anytime soon?

[DarKSunrise]

Actually hold on - do you need to run this on a dedicated server?

By looking at the code, it should error with "gm_pvs: You must run this on a dedicated server" if it's not a dedicated server, but it never seems to throw this error when I try to run it on my listen server.

[Spacetech]

With the help of chrisaster the module now works again!
I also renamed the module to gmsv_pvs

[Drew P. Richard]

I love you.

[Odahilys]

Excuse me, Spacetech, but has anyone told you that you are worthy of a massive high five?

[DarKSunrise]

Awesome, thanks a lot!

[Mr.Thorn]

Danke.

[Drew P. Richard]

It would appear that the new Source update has caused SameInstance to not even be called anymore, no errors are returned though. Could you please look into it plox?

[Buggzie]

So, you can make a timer to go through all the entities one by one, or a few at a time to prevent getting a an overflow kick, is this right?

I'm sorry, but you ask a lot of stupid questions.

I appreciate your help, also it was one question you dumbass.

What's this addon exactly do I was asking.

[Drew P. Richard]

Read the first 2 lines of the OP.

[Nexus435]

Seems returning false only makes you not able to hear the entity.. but everything else seems unaffected?

[Spacetech]

It broke due to a source engine update and I have been unable to fix it.

[DylanWilson]

was this ever fixed? I have a need for it

[Nexus435]

I haven't used it in a while. Tell me whats wrong and I'll look into fixing it. The vmt indexes are probably wrong.

[TGiFallen]

this hook is added in the next version of gmod.

[Ruzza]

Is it possible to use this with util.Trace and see if theres a wall infront of the player before they can hear/see the entity behind the wall making wallhacks useless?

[Nexus435]

Ruzza posted:

On the next update I would say it is completely possible. Depends on what data is sent regardless of the hook.

[NightExcessive]

Does anyone have a version of this that's been updated for GMod 13?
