Thanks, but I've already created the data, so the problem won't be there. At least I think so
In that case it might be handy if we know at which line + file the error is occurring.

info-system command lines;
SELECT * FROM `informationicons` AS infoIcons WHERE infoIcons.id IS NULL OR infoIcons.x IS NULL OR infoIcons.y IS NULL OR infoIcons.z IS NULL OR infoIcons.interior IS NULL OR infoIcons.dimension IS NULL
Does this query gives you any results? (run in mysql interface)
(note this query does only check for null values)
If this query does not give you results.
Add a log to the following function, in case of a missing x, y or z, it will log the ID of that database row (and abort the loading process).
function loadAllInformationIcons() local ticks = getTickCount( ) local counter = 0 local result = mysql:query("SELECT * FROM `informationicons`") while true do local row = mysql:fetch_assoc(result) if not row then break end local id = tonumber(row["id"]) local createdby = tostring(row["createdby"]) local x = tonumber(row["x"]) local y = tonumber(row["y"]) -- bunlar tuhaf local z = tonumber(row["z"]) local rx = tonumber(row["rx"]) local ry = tonumber(row["ry"]) local rz = tonumber(row["rz"]) local interior = tonumber(row["interior"]) local dimension = tonumber(row["dimension"]) local information = tostring(row["information"]) --------------------------------------------- if not x or not y or not z then iprint("Data is corruption starts at ID", id) break end --------------------------------------------- informationicons[id] = createPickup(x, y, z, 3, 1239, 0)--createObject(1239, x, y, z, rx, ry, rz) setElementInterior(informationicons[id], interior) setElementDimension(informationicons[id], dimension) setElementData(informationicons[id], "informationicon:id", id) setElementData(informationicons[id], "informationicon:createdby", createdby) setElementData(informationicons[id], "informationicon:x", x) setElementData(informationicons[id], "informationicon:y", y) setElementData(informationicons[id], "informationicon:z", z) setElementData(informationicons[id], "informationicon:rx", rx) setElementData(informationicons[id], "informationicon:ry", ry) setElementData(informationicons[id], "informationicon:rz", rz) setElementData(informationicons[id], "informationicon:interior", interior) setElementData(informationicons[id], "informationicon:dimension", dimension) setElementData(informationicons[id], "informationicon:information", information) counter = counter + 1 end
After wards you can look the id up like this (replace ID 1 with the one in the debug logs)
SELECT * FROM `informationicons` AS infoIcons WHERE infoIcons.id = 1

But for some reason this line of code is not good.
You might want to check if there is actually is data and what the data structure is.
iprint("Validating variable Data:", inspect(Data)) -- debug in /debugscript 3 if not Data then return LogAlert("EmptyRectangle") end -- something is really wrong local loginCredentials = Data[1] if not loginCredentials then return LogAlert("EmptyRectangle") end -- no loginCredentials local username = loginCredentials[1] local pass = loginCredentials[2] if (username ~= "" or pass ~= "") then return LogAlert("EmptyRectangle") end -- no user name of password triggerServerEvent("attemptLogin", resourceRoot, username, hash("sha512", pass))

how can i convert pt unit to mta dx scale unit in photoshop?
The units of png and jpg are always measured in pixels. In Photoshop you can edit your settings to pixels. (Edit > Preferences > Units & Rulers)
Scaling of images can be optimised by enable mipmap. Mipmaps are smaller copies of the original, making rendering smaller variants faster. Mipmaps will be recreated every time you create a texture with dxCreateTexture (by default mipmaps are enabled, see argument mipmaps).

I want to stop the process of riding any car, whether I am glued
You will have to cancel the following event when you are glued. You can for example check if the player is attached to anything and then cancel the event.
https://wiki.multitheftauto.com/wiki/OnVehicleStartEnter
addEventHandler ( "onVehicleStartEnter", root, function (player) if getElementAttachedTo (player) then -- check here if you are glued or not. cancelEvent() end end )

You can give this utility function a try (untested). It is important to know that you can only check this information serverside.
--[[ Check if the player is inside of an acl group with a specific name Argument 1: player element Argument 2: aclGroupName string ]] function isPlayerInAclGroupWithName (player, aclGroupName) -- Check if the player argument is filled in correctly if not isElement(player) or getElementType(player) ~= "player" then error("Expected player element at argument 1, got " .. inspect(player), 2) end -- Check if the aclGroupName is filled in correctly if type(aclGroupName) ~= "string" then error("Expected string at argument 2, got " .. inspect(aclGroupName), 2) end -- Get the player account and check if the player is logged in local account = getPlayerAccount ( player ) if isGuestAccount(account) then return false end -- Get the acl group local aclGroup = aclGetGroup ( aclGroupName ) if not aclGroup then return false end -- Check if the account name of the user is inside of the acl group local accountName = getAccountName ( account ) return isObjectInACLGroup ("user." .. accountName, aclGroup) end
Usage:
if isPlayerInAclGroupWithName(player, "police") then outputChatBox("I am the police", player) end

Probably i dont know something about mysql or JSON
Please show the JSON, that is the easiest way of checking why the conversion is failing.
Also don't use the following array formatting:
{ [1] = {}, [2] = {} }
Keep it clean, no gaps if possible, if you do have gaps add a false value or an empty table:
{ {}, {} }
The conversion between Lua and JSON is rather sensitive if you do not follow the JavaScript Object Notion rules.
Another golden rule:
Don't mix keys of different key types, it is either strings or integer each (sub)table. If one of them is a string, all of them become strings. There is no such thing as a table in JavaScript, there is only an default object(key strings) or an array(key integers).-

but what does each of them mean?
A matrix is a mixture of a position and orientation(rotation). With as main purpose able to calculating offset. For example you want to place a ramp in front of a vehicle, a matix helps you with that.
But you do NOT need to know how a matrix works, don't waste your time XD.
I prefer to use the Matrix class(without oop), instead of getElementMatrix:
local x, y, z = getElementPosition(vehicle) local xr, yr, zr = getElementRotation(vehicle) local vehicleMatix = Matrix (Vector3(x, y, z), Vector3(xr, yr, zr)) -- build your matrix with position and rotation local offset = Vector3(0, 0, 0) -- fill in! local newPosition = matrix:transformPosition(offset) iprint(newPosition.x, newPosition.y, newPosition.z)
See docs:
https://wiki.multitheftauto.com/wiki/Matrix
Utility function:
function getMatrixFromElement (element) return Matrix (Vector3(getElementPosition(element)), Vector3(getElementRotation(element))) end

There is also this serverside function:

QuoteThis function gets the amount of time in milliseconds that a players position has not changed.
Or check when the player is pressing a button:

can you explain me how is it works?
How validation works?
When data comes from an external source, in this case element-data, there is no way of knowing that it is valid. Therefore checking if the data is OK is essential.
For example if the script tries to get the element-data under the key "char:items" before it has an value assigned to it, the script without data validation will most likely end up with an warning or error at a certain point.
25 minutes ago, kukimuki said:and what you written me code is good for me?
Are you suggesting that it is not good for you? Well this is more or less the format in which you receive help in this forum section.
If I misunderstand you, please let me know.

I inserted the client file.
Always validate your element-data before you are going to do something with it:
local inv = getElementData(localPlayer, "char:items"); ----------------------------------------------- assert(type(inv) == "table", "inv must be a table") -- hard error -- or if type(inv) != "table" then -- outputChatBox("OH NO, I need a table to put my head on...") return end
If element data is not set, the variable inv does not contain a table, but false instead.

Another way would be manually modify the ACL:
<right name="command.theCommand" access="false" /> <right name="command.theCommand" access="true" />
And set restricted to true (this is the syntax for addCommandHandler):
bool addCommandHandler ( string commandName, function handlerFunction [, bool restricted = false, bool caseSensitive = true ] )
This will restrict specific commands based on the ACL.
The choice depends where you want the restriction/validation being placed. During executing the command or in the function of the script.

What is the reason for that ?
You might consider using another filename. Also stopping the resource on onResourceStart is a good way for error handling, since this resource is not very useful without a databasse.
addEventHandler ( "onResourceStart", resourceRoot, function () vehDB = dbConnect( 'sqlite', 'veiculosdatabase.db' ) if not vehDB then return cancelEvent (true, "Unable to connect to database.") end dbExec( vehDB, ' CREATE TABLE IF NOT EXISTS `VehiclesSystem_Players` (pSerial, vehID, vehName, vehPrice, Subscription) ' ) end, false)

I'm undecided between these two but do you have a better idea?
2 hours ago, Burak5312 said:local allpeds = {} local testped = createPed(0, 0,0,3) allpeds[testped] = true
For easy and fast management.
2 hours ago, Burak5312 said:local allpeds = {} local testped = createPed(0, 0,0,3) table.insert(allpeds, testped)
For looping speed. (complexer management)
Note: you can also go for both.
Or you could go for this one:
https://wiki.multitheftauto.com/wiki/CreateElement (as parent)
https://wiki.multitheftauto.com/wiki/SetElementParent
Benefits:
- No need to clean up after a ped is deleted.
- Able to get specific streamedin peds at clientside.
- Attach eventHandlers to all your peds and only those.
- (Whipe all peds with just one destroyElement call > propagation.)

maybe I don't know my way of thinking is wrong but right now I can't see any way out
AI thinking is not linear unfortunately. But some tasks are, and yet those probably can be interrupted in some way. Therefore it is important to run some of the checks every cycle.
You could give something like this a try:
local dataStorage_AI = {} -- Give the ped a brain if it hasn't one yet. function init_AI (ped) if dataStorage_AI[ped] then return end dataStorage_AI[ped] = { controls = {}, -- pressed controls maybe? (since serverside is not aware) element = ped } end -- Run the main update cycle function update_AI(ped) if not dataStorage_AI[ped] then return end -- no storage, no brain... if isPedDead(ped) then return end if isElementInWater(ped) then return runPedInWaterInstructions (ped) end end -- If the ped is in the water, do stuff here function runPedInWaterInstructions (ped) local pedData = dataStorage_AI[ped] -- do something here end

Is there a way to show where the problem is?
You can inspect resource usage with the performancebrowser:

Might be, it also depends what is spammed. For example a command (attached to a synced database query) can be more impactful than just a chat message.

I want to use datalist in html, I tried it and it doesn't work.
I tested your code and it works fine.
But keep in mind that in your current setup it is used as an auto complete feature. Typing `Jo` makes auto complete John available. Also when you press your arrow-down key, it should act more as the options tag as @FLUSHBICEPS referring to.

How do you make a function loaded with loadstring() that also supports parameters?
When loading code, you are putting a kind of chunk/function around it.
So basically this:
function(player) return getPlayerName(player) == 'owner' end
Looks more or less like this:
-- pcall(loadstringed) is calling this chunk/function: function () function(player) return getPlayerName(player) == 'owner' end end
So in order to solve this:
return function(player) return getPlayerName(player) == 'owner' end
local success, theFunc = pcall(loadstringed) local success2, isOwner = pcall(theFunc, testPlayer)
See also xpcall for better error handling:

I mean Multi Game Mode
The generic answer is, you need to create a resource that serves as manager
> and rewrite each gamemode, so that their usage can be scoped(data/elements/events) for specific players.Best is to get inspiration from an already existing Multi Game Mode resource. Since this is really a lot of work and complexity. Explaining the process from A to B would take too much of my time (sorry).

then the handlers will stop working on other resources!
When the resource starts a new resourceRoot element will be created. This element is destroyed when the resource stops.
It is therefore not a good idea to attach eventHandlers to the resourceRoot's of other resources. (Unless you keep track of start/stop resources)
In your current example you mentioned the eventName onPlayerFirstSpawn.
The player makes it's first spawn. From a semantic perspective, the player is therefore the one activating the event. And I expect it therefore to be used as the source of that event. The element above a player is the root element and should be used for the eventHandler of that event. The root element is not deleted when restarting resources.
But never the less, here is how to solve the resource validation issue:
addEventHandler("<eventName>", root, function () local resource = getResourceFromName( "<resourceName>" ) if not resource then return end if source == getResourceRootElement(resource) then -- The source is from the correct resource end end)
Another way to keep the resource start up in order is to use the tag: <include resource="resourceName"/>

I tried to do something similar.
Looks nice! Just some side notes, feel free to ignore those.
I recommend not do these kind of animations serverside. You are basically sending data to the client/player every 20 milliseconds, which might causing network trouble on a not local server. Just set the end-value serverside. And trigger an even clientside + do the animation there.
Also the GTA default money animation can be displayed with setPlayerMoney (unless of course you want to use a custom transition): https://wiki.multitheftauto.com/wiki/SetPlayerMoney

The information system has been corrupted.
in Scripting
Posted
The tonumber function is used to convert a string to a number. A string is basically text "abcdef12345!@$#%" and a number is 1234567890.
Why is it trying to convert a string to a number? Probably just to be sure, since the code will not work if strings are using for example for the position x, y, z
This function is used to add information icons.
Please specify errors are shown when using the following command:
And mark them in the function with a comment:
