    the Russians and Brazilians go to the server and kick out the players with that message and I don't have any triggerServerEvent where the player is kicked out... I don't understand how it could be a security flaw in my server that allows a player to come in and kick everyone out just like that. If it's a security issue, it should be with the administration panel, not my server. The problem is that when someone comes to seek help on the forum, all they find is people judging their comments and others downplaying the situation, nothing new.


    Make sure to update all default (and community) resources. Keeping them outdated could lead to such scenarios, where they could make use of incorrectly written logic.
    Disable access to load and loadstring in ACL, unless you have certain reason to keep it enabled (latest MTA builds have it disabled by default).
      

    <right name="function.loadstring" access="false"/>
<right name="function.load" access="false"/>

    You could take a look at Script security article, which i've recently updated.
    Also, there's no such anti-cheat which would protect you from vulnerable Lua code running on your server, so blaming it in first place isn't reasonable - which most of people nowadays shamelessly do. Including ungratefulness towards AC team, which provided nearly cheat-free experience for a few good years.

    Siema guys. Ktoś mądry opatentował już dobre skalowanie pod 4K w dół?

    Chodzi o DOBRE skalowanie, moje niestety nie sprawdza się dobrze, owszem zachowuje proporcje względem zmniejszania ekranu ale jednak czcionka jest za małą już na FullHD.

    Executing Server Functions on the Client Side with a Return Value

    I need to get the result of a server function from an event handler. 

    local plTeam = getPlayerTeam(localPlayer)
if plTeam then
  if isPlayerInTeam(plr, plTeam) then
    local friend = getPlayerFriend(plr) -- Execute server-side function "getPlayerFriend(player)"
    text = friend.." ["..id.."]"
  end
end

     

    Try this, but carefully read full page. Might require some changes though.

    Fade Sound

    Hi there. ? Below is a simple client-side code that allows us to play a song by command. For our stopMusic function I've made an array of setTimer's to bring down the volume ? before stopping the song completely, ? thus achieving a fadeout effect. It works alright but i feel like there must be a much cleaner or simplified way of doing this: Which would be the best? ?

      

    function playMusic()
	song = playSound("music/track_05.mp3", true)
	setSoundVolume(song, 1)
end
addCommandHandler("pmusic", playMusic)

function stopMusic()
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.95) end end, 100, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.90) end end, 200, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.85) end end, 300, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.80) end end, 400, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.75) end end, 500, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.70) end end, 600, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.65) end end, 700, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.60) end end, 800, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.55) end end, 900, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.50) end end, 1000, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.45) end end, 1100, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.40) end end, 1200, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.35) end end, 1300, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.30) end end, 1400, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.25) end end, 1500, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.20) end end, 1600, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.15) end end, 1700, 1)

	setTimer(function() if isElement(song) then setSoundVolume(song, 0.10) end end, 1800, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.09) end end, 1900, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.08) end end, 2000, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.07) end end, 2100, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.06) end end, 2200, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.05) end end, 2300, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.04) end end, 2400, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.03) end end, 2500, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.02) end end, 2600, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0.01) end end, 2700, 1)
	setTimer(function() if isElement(song) then setSoundVolume(song, 0) end end, 2800, 1)

	setTimer(function() if isElement(song) then	--Destroy the sound element
		destroyElement(song) 
	end 
	end, 2900, 1) 
end

    Oh, ty  :)

    I am looking how to enable this, I tried to use the old freeroam resources that came with the mta files, but some cause errors

    I appreciate any help :)

    Perhaps freeroam/fr_client.lua (line 60)

    For the next time please use Find in files feature, which should be available in any decent code editor. It's CTRL + SHIFT + F for Sublime Text.

    Hit markers are probably based off attacker sync, use onClientPlayerDamage event (bind it to root), check if attacker equal to localPlayer, and then kill player if required (triggerServerEvent, and kill player server-side)

    If you mean command then you could use optional argument for addCommandHandler.
      

    bool addCommandHandler ( string commandName, function handlerFunction [, bool restricted = false, bool caseSensitive = true ] )
    Quote

    restricted: Specify whether or not this command should be restricted by default. Use this on commands that should be inaccessible to everyone as default except special users specified in the ACL (Access Control List). This is to make sure admin commands such as ie. 'punish' won't be available to everyone if a server administrator forgets masking it in ACL. Make sure to add the command to your ACL under the proper group for it to be usefull (i.e <right name="command.killEveryone" access="true"></right>). This argument defaults to false if nothing is specified.

     

    Tag team, admin does not work, any solution?

    in Scripting

    Posted · Edited by srslyyyy

    From what i can see the or operator is missing here.
      

    if teamName == "~STAFF" isObjectInACLGroup("user."..account, aclGetGroup("Admin")) then

    It should looks like this:
      

    if teamName == "~STAFF" or isObjectInACLGroup("user."..account, aclGetGroup("Admin")) then

    Also you need one more end which will close function scope.

    [HELP] Change damage from an explosion

    in Scripting

    Posted

    17 hours ago, Ryuto said:

    Hello, I open this post to ask if it is possible to increase or decrease the damage caused by an explosion and what functions I can use to achieve it.

    You would need to use cancelEvent() (to cancel default behaviour) in onClientVehicleDamage and write your own damage system via this event.

    CPU usage , client

    in Scripting

    Posted · Edited by srslyyyy

    I have a question

    What are the normal values for cpu usage for client?

    For example, for something like this(text above npc head): Screen

    Now 2.03% is used there but how good is that?

    Maybe I can reduce the load in some way or are these normal numbers? 

    


function testcpu()
	local x, y, z = getCameraMatrix()
	local dimension = getElementDimension(localPlayer)
			local px, py, pz = getElementPosition(getElementByID("ped1"))
			local distance = getDistanceBetweenPoints3D(px, py, pz, x, y, z)
			if distance <= 7 then
                local sx, sy = getScreenFromWorldPosition(px, py, pz + 1.2)		
    			if sx and sy then
						dxDrawText("Unknown", sx, sy, sx, sy, tocolor(3, 169, 252, 255), 2.02, "default-bold", "center", "center", false, false, false, false, false)
      			end
			end
end
addEventHandler("onClientRender", getRootElement(), testcpu)

     

    If you wanna keep script in this state, i will explain what could be done better. Start off by:
    Saving an function call in: 

    local dimension = getElementDimension(localPlayer)

    Currently, you are returning it every frame, while you could save it in main scope and avoid calling it. By using onClientElementDimensionChange to store localPlayer's current dimension. 

    local dimension = 0

function onClientElementDimensionChange(_, newDimension)
	dimension = newDimension
end
addEventHandler("onClientElementDimensionChange", localPlayer, onClientElementDimensionChange)

    Saving an another function call: 

    local px, py, pz = getElementPosition(getElementByID("ped1"))

    I'm assuming that custom element is created on script init, otherwise you would need to update it at the time it creates. 

    -- Main scope

local myPed = getElementByID("ped1")

-- Render scope

local px, py, pz = getElementPosition(myPed)

    For next step, you could use custom implementation of getDistanceBetweenPoints3D which is faster from MTA (thanks @Sarrum)
      

    local function getDistance3D(pFirstX, pFirstY, pFirstZ, pSecondX, pSecondY, pSecondZ)
	pFirstX, pFirstY, pFirstZ = pFirstX - pSecondX, pFirstY - pSecondY, pFirstZ - pSecondZ

	return (pFirstX * pFirstX + pFirstY * pFirstY + pFirstZ * pFirstZ) ^ 0.5
end

    Another thing which most of scripters forget about is using tocolor in render, even if color doesn't change...
      

    tocolor(3, 169, 252, 255) -- notice () - a function call which returns same color every frame

    The solution will be to save it in local variable in main scope and later use it.
      

    -- Main scope

local textColor = tocolor(3, 169, 252, 255)

-- Render scope

dxDrawText("Unknown", sx, sy, sx, sy, textColor, 2.02, "default-bold", "center", "center", false, false, false, false, false)

    If color isn't static you could use, for example events or timers which will be ideal way to update it.

    Other than that, you might use onClientElementStreamIn/onClientElementStreamOut to add/remove handler when ped appears or disappears from stream zone, as mentioned above by Dutchman101.

    Hi, how to do something like this when the checkbox is selected in the login panel, it saves the data (login and password)

    There's a guide for this -

    See How to add "remember me" functionality. You shouldn't store password on client-side, even encoded.
