[Solved]Save/load multiple value

Hello.
I have two problems (related with the title)...
1 - I do not remember how to load the values. Plus, how to load more than one value?

1
2
3
4
5
6
7
8
9

function svJoin(id)
	if (player(id,"usgn") > 0) then
		local file = io.open ("sys/lua/USGN/"..player(id,"usgn")..".txt","r")
		if (file) then
			file:read () <--- ???
			file:close ()
		end
	end
end

Note: Don't mind the arrow, it just want to guide you the problem.

Those values are Kill[id],Dead[id] and KDR[id].

2 - Any way to make content in saved folder has separated (neat) text?

1
2
3
4
5
6
7
8

This is "..player(id,"usgn")..".txt
--------------------------------------------------
Name: "..player(id,"name").."
Kill: "..Kill[id].."
Deaths: "..Dead[id].."
etc
etc
etc

While this is the save script:

1
2
3
4
5
6
7

function svLeave(id)
	if (player(id,"usgn")> 0) then
		local file = io.open ("sys/luaUSGN/"..player(id,"usgn")..".txt","w")
		file:write ("Name: "..player(id,"name").." | Kill: "..Kill[id].." | Deaths: "..Dead[id])
		file:close ()
	end
end

For now, I just use the '|' as separator.

Any solutions are welcome.

Sorry I'm not actually answering your question, but I use this script to load and save values.

Yates, your solution is useful, but...

Console has written

This is the part of code if you want to view and fix it.

Rename the local values:

1
2
3
4

local lrKill, lrDead, lMVP = file:read("*n","*n","*n")
rKill[id] = lrKill
rDead[id] = lrDead
MVP[id] = lMVP

I just put an l infront of them for local. Change them to whatever you want if this solution works.

I think it's because you have a table called rKill and are trying to create a local value with the same name and use it as a number value.

And if this works, change the save script as well..

[Solved] oh.. wait..!

local sKill, sDead, sMVP = rKill[id], rDead[id], MVP[id]
file:write (sKill.."\n"..sDead.."\n"..sMVP)

It can't concatenate sMVP because it's equal to nothing (doesn't exist).

sMVP = MVP[id]

MVP[id] has no value. Check if you set the value correctly and if you don't, that's your problem.

I tried to remove the MVP[id], the problem still appears (assume at the end of the sMVP was sDead, Dead[id] also error in this case, following sKill). There has something that I doesn't need to edit leave function, which was working...

Can you tell us what error is shown on print? (If any).

Oh no... I've discovered that the only successful way to load values are by through:

1
2
3
4
5
6
7
8
9
10

function load(id)
	if (player(id,"usgn") > 0 then
		local file = io.open ("directory/"..player(id,"usgn")..".txt","r")
		if file then
			value[id] = file:read("*n") <---
			value2[id] = file:read(*n") <---
			file:close ()
		end
	end
end

Those pointed variables are the only reliable...
Finally, thanks to you guys for helping me especially user

Yates

Yates: The error that I'd realise was the way to save the file.

1
2
3

local 1a, 1b, 1c = a[id], b[id] c[id]
file:write (1a.."\n"..1b.."\n"..1c)
file:close

There was no error in the script. The only problem is the way to save it.

Well it worked without changing to those exact values so it was probably an error in setting/naming them the same as something else but if it works for you glad to help out.
