SinaAmp · February 3, 2022

hello guys

i working on hunger and thirst system. i can save and get data with get and setaccountdata but when i try to change the saving way to mysql i got errors

here is my script:

Spoiler

addEventHandler ("onPlayerLogin",root,function(_,Acc)
local MainHunger2 = getAccountData (Acc,"AmpHunger")  --i want to change this
local MainThirst2 = getAccountData (Acc,"AmpThirst")
        if MainHunger2 == false then
        setElementData (source,"hunger",100)
        else
        setElementData (source,"hunger",MainHunger2)
        end
            if MainThirst2 == false then 
            setElementData (source,"Thirst",100)
            else
            setElementData (source,"Thirst",MainThirst2)
            end 
end)

function saveAccountData ( account )
    if isGuestAccount ( account ) then
        return false
    end
    Player = getAccountPlayer (account)
Hungers = getElementData (Player,"hunger")
Thirsts = getElementData (Player,"Thirst")
setAccountData (account,"AmpHunger",Hungers)
setAccountData (account,"AmpThirst",Thirsts)
end

addEventHandler ( 'onPlayerQuit', root, function ( )
    local acc = getPlayerAccount ( source )
    saveAccountData ( acc )
end )


addEventHandler( "onResourceStart", getResourceRootElement( getThisResource() ), function( )
 for _, plr in pairs( getElementsByType( "player" ) ) do 
 local Acc = getPlayerAccount (plr)
    if not isGuestAccount (Acc) then
    local MainHunger = getAccountData (Acc,"AmpHunger") -- and this
    local MainThirst = getAccountData (Acc,"AmpThirst")
        if MainHunger == false then
        setElementData (plr,"hunger",100)
        else
        setElementData (plr,"hunger",FomeAcc)
        end
            if MainThirst == false then
            setElementData (plr,"thirst",100) 
            else
            setElementData (plr,"thirst",SedeAcc)
            end 
    end    
 end
 end)
 
 
 addEventHandler ("onResourceStop",getResourceRootElement( getThisResource()),function()
for index,players in ipairs(getElementsByType("player")) do 
 local acc = getPlayerAccount ( players )
 saveAccountData ( acc )
end
end)

also i have clinet side script but that not needed

You can use the previous examples for this, add 2 more rows to the database and get the information with select queries. You can use the update command to change it.

SinaAmp · February 4, 2022

i edited the code but i got this two errors:

1- attempt to index field '?' (a nil value)

2- Bad argument @ 'getAccountName' [Expected account at argument 1, got nil]

please review my code @Burak5312

can you try this again 
what's the problem on the client side?

every thing works fine till i quit the server i got dbExec failed; (1205) Lock wait timeout exceeded; try restarting transaction

my thirst works fine but Hunger is still stuck at 100

SinaAmp · February 4, 2022

@IIYAMA @The_GTA

i think it's impossible to complete this metode with set and get elemnt

isn'n better to use one variable instead of using get,set element?

βurak · February 4, 2022

I'm not sure but can you remove LIMIT 1 for hunger?

local AccData = dbPoll(dbQuery(db,"SELECT Hunger,Thirst FROM stats WHERE Account=? LIMIT 1", AccName), -1)

local AccData = dbPoll(dbQuery(db,"SELECT Hunger,Thirst FROM stats WHERE Account=?", AccName), -1)

SinaAmp · February 5, 2022

after disconnecting from server i got these errors i think it's for wrog argument for onplayerquit:

line 55: Bad argument @ 'getPlayerAccount' [Expected element at argument 1, got string 'Quit']
line 59: Bad argument @ 'getAccountName' [Expected account at argument 1, got boolean]
line 60: Bad argument @ 'getElementData' [Expected element at argument 1, got string 'Quit']
line 61: Bad argument @ 'getElementData' [Expected element at argument 1, got string 'Quit']

these top issues fixed

bu i still got this error after quit from server:

dbExec failed; (1205) Lock wait timeout exceeded; try restarting transaction

I don't know this error maybe you can ask someone else

oh i found whats wrong

i had too many update requests after onplayerquit in another resources

after i stoped another resources with db update in their code my problem was solved

but i need to use db update in my another resources

thank you bro

maybe @IIYAMA can help

SinaAmp · February 5, 2022

i solved the problem with using callback for must of them but some of them when i use callback get attempt to call global ' ' nil value

like this code:

Spoiler

function getpaccount (_,account)
	local AccName = getAccountName(account)
	local Setpname = setPlayerName(source,tostring(AccName))
	local AccData = dbQuery(AccDatacallback(), db,"SELECT * FROM stats WHERE Account=? LIMIT 1", AccName)
	function AccDatacallback(AccData)
		local result = dbPoll( AccData, 0 )
	end
	if(AccData) then 
       if(#AccData > 0) then return end
	end
	local ID = getFreeID()
	local SetData = dbExec(db,"INSERT INTO stats (ID,Account) VALUES (?, ?)",ID, AccName)
end
addEventHandler("onPlayerLogin",root, getpaccount)

βurak · February 5, 2022

Try changing 0 to -1 for dbPoll

function getpaccount (_,account)
	local AccName = getAccountName(account)
	local Setpname = setPlayerName(source,tostring(AccName))
	local AccData = dbQuery(AccDatacallback(), db,"SELECT * FROM stats WHERE Account=? LIMIT 1", AccName)
	function AccDatacallback(AccData)
		local result = dbPoll( AccData, -1 ) --this
	end
	if(AccData) then 
       if(#AccData > 0) then return end
	end
	local ID = getFreeID()
	local SetData = dbExec(db,"INSERT INTO stats (ID,Account) VALUES (?, ?)",ID, AccName)
end
addEventHandler("onPlayerLogin",root, getpaccount)

I updated Burak his example. But I have not refactored the variable names.

function AccDatacallback(AccData, player, account, AccName)
  local result = dbPoll( AccData, 0 )

  if AccData and #AccData > 0 then return end

  local ID = getFreeID()
  local SetData = dbExec(db,"INSERT INTO stats (ID,Account) VALUES (?, ?)", ID, AccName)
end

function getpaccount (_,account)
	local AccName = getAccountName(account)
	setPlayerName(source,tostring(AccName))

	dbQuery(AccDatacallback, {source, account, AccName}, db, "SELECT * FROM stats WHERE Account=? LIMIT 1", AccName)

end
addEventHandler("onPlayerLogin",root, getpaccount)

The function was called instead of provided as function.

local AccData = dbQuery(AccDatacallback(), db,"SELECT * FROM stats WHERE Account=? LIMIT 1", AccName)

This is now moved inside of the call back function. Since the data is not immediately available.

if(AccData) then 
       if(#AccData > 0) then return end
	end
	local ID = getFreeID()
	local SetData = dbExec(db,"INSERT INTO stats (ID,Account) VALUES (?, ?)",ID, AccName)

SinaAmp · February 6, 2022

For this line:

if AccData and #AccData > 0 then return end

i got this error:

attempt to get length of local 'AccData' (a userdata value)

βurak · February 6, 2022

change with result

if result and #result > 0 then return end

SinaAmp · February 6, 2022

thank you guys problem solved

SinaAmp · February 6, 2022

sorry @IIYAMA but i still got dbExec failed; (1205) Lock wait timeout exceeded; try restarting transaction

i had 15 dbexec in my resources. 3 of them must work after player logout

when i decrease them (dbexec's) by stop one of the resources. after that i hadn't this issue but when 3 of them work's together i got that error

aslo i added the callback for all of my dbquerys

maybe that's for timing issue in my hunger and thirst system

Spoiler

function saveAccountData (player)
      local playerAccount = getPlayerAccount(player) 
      if(playerAccount) then
         if(isGuestAccount(playerAccount)) then return end
      end
      local AccName = getAccountName(playerAccount)
  
      local Hungers = getElementData (player,"Hunger")
      local Thirsts = getElementData (player,"Thirst")
      dbExec(db,"UPDATE stats SET Hunger=?, Thirst=? WHERE Account=?",Hungers, Thirsts, AccName)
      end
      
      addEventHandler ( 'onPlayerQuit', root, function ( )
          saveAccountData(source)
      end )

i think in this code dbexec doesn't get data from Hungers and thirsts variables

you can debug it with outputDebugString to find out

outputDebugString(Hungers)
outputDebugString(Thirsts)

SinaAmp · February 6, 2022

i got my hunger and thirst number

You can increase the lock wait timeout:

https://stackoverflow.com/questions/6000336/how-to-debug-lock-wait-timeout-exceeded-on-mysql

There are multiple reasons why this error can occur, so maybe that will not be enough.

Also consider to index your most used columns, like Account:

https://www.w3resource.com/mysql/creating-table-advance/create-index.php

This will speed up your search queries.

But de-increase the speed of removal queries. (which you probably only use when removing accounts)
