[HELP] Save "NWInt" value's

[timmybo5]

hey, i am back again with some more questions ...

I tried to make a save function for my custom "Hunger Bar" mod, the only problem is that is doesn't work

purpose: when the player leaves with 25% hunger, it should be there when he rejoins

any help is highly appreciated !

function HungerSave( ply )
	if (file.Exists( "hunger_data/" .. tostring( ply:UniqueID() ) .. "hunger.txt", "DATA" )) then
		local Data = util.JSONToTable(file.Read( "hunger_data/" .. ply:UniqueID() .. "hunger.txt", "DATA" ));
		for k, v in pairs( Data ) do
			ply:SetNWInt("Hunger")
		end 
	end
end
hook.Add("PlayerInitialSpawn", "HungerSave", HungerSave)

function HungerSave( ply )
	local filename = "hunger_data/" .. tostring( ply:UniqueID() ) .. "hunger.txt"
	local Hungertable = {}
		for d, f in pairs( ply:GetNWInt("Hunger") ) do
			table.insert( Hungertable, f:GetNWInt("Hunger") )
		end 
	local data = util.TableToJSON( Hungertable )
	file.Write( filename, data )
end
hook.Add( "PlayerDisconnected", "HungerSave", HungerSave )

No errors are thrown out.

You're not setting "ply:SetNWInt("Hunger")" to anything at line 5.

@Jacob, i don't know how to work with Pdata, could u show me an example ?

@Brandon, how can i set it to the value it is supposed to load ?

PData works similarly to NWInt ( Syntax ), except it doesn't sync with client, but it saves its value over a restart.

[timmybo5]

@Robotboy, how could i implement it in a save ?

What? It saves automatically, but it doesn't send the values to clients.

ply:SetNWInt( "Hunger", v )

[timmybo5]

it doesn't work

function HungerSave( ply )
	if (file.Exists( "hunger_data/" .. tostring( ply:UniqueID() ) .. "hunger.txt", "DATA" )) then
		local Data = util.JSONToTable(file.Read( "hunger_data/" .. ply:UniqueID() .. "hunger.txt", "DATA" ));
		for k, v in pairs( Data ) do
			ply:SetNWInt( "Hunger", v )
		end 
	end
end
hook.Add("PlayerInitialSpawn", "HungerSave", HungerSave)

function HungerSave( ply )
	local filename = "hunger_data/" .. tostring( ply:UniqueID() ) .. "hunger.txt"
	local Hungertable = {}
		for d, f in pairs( ply:GetNWInt("Hunger") ) do
			table.insert( Hungertable, f:GetNWInt("Hunger") )
		end 
	local data = util.TableToJSON( Hungertable )
	file.Write( filename, data )
end
hook.Add( "PlayerDisconnected", "HungerSave", HungerSave )

and this error appears
note: the hunger_data file remains empty

Pdata is unrelated to file.Write. It saves to a database, not a .txt file.

[timmybo5]

@BFG i am not using Pdata, only "NWInt"

[Rubat]

for d, f in pairs( ply:GetNWInt("Hunger") ) do

Your problem lies here. ply:GetNWInt("Hunger") return a number, and pairs expect a table.

[timmybo5]

mm, how can i let expect a number ?

[QUOTE=timmybo5;43935540]@BFG i am not using Pdata, only "NWInt"[/QUOTE]

Well your best bet would be to use pdata, and also both your functions have the same name, which they shouldnt

[Rubat]

[QUOTE=timmybo5;43935670]mm, how can i let expect a number ?[/QUOTE]

You can't. You [b]must[/b] give it a table, that' how how function works.

[QUOTE=Robotboy655;43935730]You can't. You [b]must[/b] give it a table, that' how how function works.[/QUOTE]

How about

for i=1, ply:GetNWInt("Hunger") do
//GAYCODE
end

[Rubat]

[QUOTE=AirBlack;43936100]How about

for i=1, ply:GetNWInt("Hunger") do
//GAYCODE
end

[/QUOTE]

And what do you expect this to do? It wont magically add all Networked variables to his table.

[AirBlack]

[QUOTE=timmybo5;43934956]Text[/QUOTE]
You should use

function HungerSave( ply )
	local filename = "hunger_data/" .. tostring( ply:UniqueID() ) .. "hunger.txt"
	local Hungertable = {}
	table.insert( Hungertable, ply:GetNWInt("Hunger") )// thx Bo98
	local data = util.TableToJSON( Hungertable )
	file.Write( filename, data )
end
hook.Add( "PlayerDisconnected", "HungerSave", HungerSave )

Sry, i haven't understand problem.

[Bo98]

[QUOTE=AirBlack;43936135]

function HungerSave( ply )
	local filename = "hunger_data/" .. tostring( ply:UniqueID() ) .. "hunger.txt"
	local Hungertable = {}
	table.insert( Hungertable, f:GetNWInt("Hunger") )
	local data = util.TableToJSON( Hungertable )
	file.Write( filename, data )
end
hook.Add( "PlayerDisconnected", "HungerSave", HungerSave )

[/QUOTE]

That f: should be ply:

[brandonj4]

OP, you can incoorporate this code by changing names and setting a max for SetMoney(SetHunger).

local savedNWVars = {
	"Hunger",
	"Whatever"
}


function LoadNWVars( ply )
	if ( file.Exists( "nwdata/" .. tostring( ply:UniqueID() ), "DATA" )) then
		local Data = util.JSONToTable( file.Read( "nwdata/" .. ply:UniqueID(), "DATA" ));

hook.Add( "ShutDown", "HungerSave", function()

end )

Saves all NWVars you put into the top table, untested.

[timmybo5]

Testing it atm

[editline]16th February 2014[/editline]

It doesn't work, not even a file appears in the nwdata folder

[timmybo5]

Bump

[timmybo5]

Solved it myself, thanks for the help anyways !
