  1. Is the error it still at this line? Or a different line? (note the resource has to be restarted) for i, item in pairs(inv) do
  2. Directly after getting the element data:
  3. There is also this serverside function: https://wiki.multitheftauto.com/wiki/GetPlayerIdleTime Or check when the player is pressing a button: https://wiki.multitheftauto.com/wiki/OnClientKey
  4. 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. 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.
  5. 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.
  6. 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.


    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)
  8. For easy and fast management. 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.)
  9. 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

    You can inspect resource usage with the performancebrowser: http://SERVER_IP:HTTP_PORT/performancebrowser/ (It will ask you to login with your ingame admin account) 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.
  11. 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.
  12. 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: https://www.gammon.com.au/scripts/doc.php?lua=xpcall
  13. 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).
  14. Try this: triggerClientEvent ( (function () local players = getElementsByType("player") for i=1, #players do if players[i] == source then table.remove(players, i) break end end return players end)(), -- IIFE (Immediately Invoked Function Expression) "runOurClientEvent", root )
  15. 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"/> https://wiki.multitheftauto.com/wiki/Resources
  16. 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
  17. Try this one instead: https://wiki.multitheftauto.com/wiki/GetPedTargetEnd Note: The returned values can be nil.
  18. I understand that you want to do the calculations your self. But if you are using a matrix, you really do not have to think about all that complex and brain exploding stuff. https://wiki.multitheftauto.com/wiki/Matrix local x, y, z, rx, ry, rz x, y, z = getElementPosition(getPedOccupiedVehicle(source)) rx, ry, rz = getElementRotation(getPedOccupiedVehicle(source)) local vehicleMatrix = Matrix ( Vector3(x, y, z), Vector3(rx, ry, rz) ) local offsetX, offsetY, offsetZ = 0, 0, 0 local newPosition = vehicleMatrix:transformPosition ( Vector3(offsetX, offsetY, offsetZ) ) SpawnedObject = createObject(987, newPosition.x, newPosition.y, newPosition.z) setElementRotation(SpawnedObject, rx, ry, rz, "ZYX") Note: You can do all of this with less lines.
  19. Just a note. Instead of doing a source validation. -- The source for this event is always 'resourceRoot' if source ~= resourceRoot then reportNaughtyness( eventName, client, "source" ) return end You can also disable propagate: addEvent("onRaiseTheRoof", true) addEventHandler("onRaiseTheRoof", resourceRoot, function(arg1, arg2) end, false -- < disable propagate ) While it does not report naughtiness, it is very easy to add.
  20. It is called a Wrapper function. It is used to add extra functionality too an existing function. For example the setElementPosition function. It's syntax is now: --[[ Syntax: setElementPosition ( element theElement, float x, float y, float z [, bool warp = true ] ) -- https://wiki.multitheftauto.com/wiki/SetElementPosition ]] All arguments except for warp are required. An example wrapper function: local _setElementPosition = setElementPosition -- Re-define original function (so that it is still accessible) function setElementPosition (element, x, y, z, warp) -- Overwrite the existing setElementPosition with your wrapper function (it is overwritten, because the function name is the same) if not x then x = 0 end if not y then y = 0 end if not z then z = 0 end return _setElementPosition(element, x, y, z, warp) -- calling the original function end The x, y, z parameters do not have to be filled in any more. They are by default set to 0. The new syntax would be now: --[[ Syntax: setElementPosition ( element theElement, [ float x = 0 ], [ float y = 0 ], [ float z = 0] [, bool warp = true ] ) -- https://wiki.multitheftauto.com/wiki/SetElementPosition ]] Is this wrapper function useful? Not really. ?
  21. Change isMapVisible() to isPlayerMapVisible(). https://wiki.multitheftauto.com/wiki/IsPlayerMapVisible isMapVisible is an OOP method. Used like this (if OOP is enabled): localPlayer:isMapVisible()
  22. Just a side note (you probably already know this: this can be the same as source, but it doesn't have to be. For example here: local myButton = createButton(0.5, 0.5, 0.1, 0.1, "Click me!", true) addEventHandler("onClientGUIClick", resourceRoot, function() outputChatBox("Button clicked!") end) this is always resourceRoot While source in this set-up is always a GUI element of this resource. For @Xwaw See image below, is the element tree, where you can see some of the main parent elements in MTA. root at the very top is the parent for ALL elements within your game: This includes players, resources(resourceRoot's) > maps/'scripted created elements' and everything that hangs directly under those. resourceRoot is the main parent of each resource. Which can be used to listen to events created by elements that are part of a specific resource. Info: https://wiki.multitheftauto.com/wiki/Element_tree
  23. @JeViCo Just wondering if cutting the process in smaller parts would give you the same effect (you never know): local width, height = dxGetPixelsSize ( rawData ) local rawDataTex = dxCreateTexture(width, height) dxSetTexturePixels (rawDataTex, rawData)
  24. While the admin acl does have this privilege, that doesn't mean that the resource is a part of it. Instead of giving admin a right that it already has. Add the resource to the admin group. <group name="Admin"> <!-- <<< --> <object name="resource.FILL_IN_THE_RESOURCE_FOLDER_NAME"></object> </group> Note: <group> and <acl> are two different tags. <group name="Admin"> <object name=""></object> <!-- user.<accountName> or resource.<resourceName> --> <acl name="Admin"></acl> <!-- ACL rights linked to this group --> </group> <acl name="Admin"> <right name="" access="false"></right> </acl>
  25. There is a difference in /refresh and /refreshall /refresh Refresh resource list to find new resources /refreshall Refresh resources and restart any changed resources https://wiki.multitheftauto.com/wiki/Server_Commands#refresh Maybe you did /refresh and not /refreshall?
