[getCursorMoveOn]

First error is caused by the function getCursorMoveOn, as it does not return any value in case isCursorShowing() returns false at line 2. Second error is because outputChatBox only accepts a player as second argument server-side (visibleTo), whilst client does not and thus expects a number (r).

[[Solved] Table inside of a table]

You get that error because number is an undefined variable, and thus equals to nil. Now, you can do table.test with alphabetical keys only - you have to do table[123] for numbers.

  
local table = { 
    test = 'a', 
    ['something'] = 'b', 
    [1] = 'c', 
    ['test2'] = 'd', 
} 
print(table.test) -- a 
print(table.something) -- b 
print(table[1]) -- c 
print(table['test2']) -- d 
---------------------------- 
local players = {} 
local player = getRandomPlayer() 
players[player] = { 
    name = getPlayerName(player), 
} 
print(players[player].name) 

[Short lua question]

Only predefined variables are these, and thus what you are trying to achieve is not possible.

[Help with Collision calculator]

It indeed does not check if given projectile has a target, but still does work with static elements. Now, you might instead do a per-frame check and find out whether an element interferes with the projectile, or through loop as in your code. I would do some sort of sight check around the projectile and check if there is any nearby approaching element that might end up colliding given its velocity within a certain distance.

Also, I had a few issues calculating what the final position is going to be and dividing by 10 worked just fine there for testing, though you might want to replace this with proper calculations.

[table.sort problem]

toptimes = { 
{32423,"nickname"}, 
{12313,"nickname"}, 
}; 
  
table.sort(toptimes, 
    function(a, b) 
        return a[1] < b[1] 
    end 
) 

table.sort basically needs minimum two values inside the input table, toptimes in this case, and then does compare these values and thus determines their order. We have got two sub-tables inside toptimes, and those tables are the ones being compared through table.sort. This is why [1] is used, we retrieve those table's index 1 value and then check which one is smaller/bigger. However, here is a similar thing I found you may have a look at.

            if attacker == localPlayer then -- in case the attacker tank's driver is the localPlayer 
                outputChatBox("Don't attack friendly tanks!", 255, 0, 0) -- a warning message is output

What about this? You could've either way tried to modify the code on your own, lol.

[unloading code which was loaded with loadstring]

I do not know, you probably ran those resources before. Err.. either way I did not check it out for a long while, they probably implemented it - quite a big security hole though.

[unloading code which was loaded with loadstring]

That is what I meant, you can not manipulate files outside a resource itself.

[unloading code which was loaded with loadstring]

Are those files even being written/created? I am not sure it is possible to actually write into a different resource location from where you are running the functions.

[Anti teamkill]

It is not working because you are using onClientVehicleDamage's arguments in a wrong way. Either way, you are using attacter at isPedInVehicle - a non-defined variable.

  
addEventHandler("onClientVehicleDamage", root, 
    function(attacker) 
        if getElementModel(source) ~= 432 then return end -- avoid this function from executing in case the vehicle that is being damaged is not a tank(?) 
        if getElementModel(attacker) == 432 then -- in case attacker's model is equal to 432 
            if getVehicleController(attacker) == localPlayer then -- in case the attacker tank's driver is the localPlayer 
                outputChatBox("Don't attack friendly tanks!", 255, 0, 0) -- a warning message is output 
            end 
            cancelEvent() 
        end 
    end 
) 
  

[unloading code which was loaded with loadstring]

Well, you can this way avoid loaded scripts from executing your actual wrappered functions. Which means that if you have set a wrapper to _triggerServerEvent and not using an environment, it can be called from inside the loaded script. And you are avoiding this by using an own environment.

[Why this error?]

Looks alright to me. Maybe you didn't pass "text" as string?

Indeed, it is in fact working fine here. So yeah, perhaps it is not a string. What is the debug error either way?

[Little Help Please]

You can either go through events and trigger a client-sided event from server-side or, create a client-sided command and execute it from server-side. Both examples:

  
-- #1 
-- Server 
addCommandHandler("kazandik", 
    function(player, command, ...) 
        triggerClientEvent(root, "kazandik_music", root) -- trigger this event for every player belonging to the root element, which should trigger for everyone in case you did not change any player's parent element 
    end 
) 
-- Client / Add the snippet bellow into your code 
addEvent("kazandik_music", true) 
addEventHandler("kazandik_music", root, 
    function() 
        startMusic() -- calling and executing startMusic 
    end 
) 
----------------- 
-- #2 
-- Server 
addCommandHandler("kazandik_all", -- As both, server and client sided commands, can not be named the same - we are using a different one 
    function(player, command, ...) 
        executeCommandHandler("kazandik", root) -- not sure if root can be used here instead of a player element directly / executing 'kazandik', your client-sided command that does the thing 
        -- and in case that does not work 
        for _, v in ipairs(getElementsByType("player")) do -- we iterate over a table returned by 'getElementsByType' that contains all players and 
            executeCommandHandler("kazandik", v) -- execute the command for each one of them 
        end 
     
    end 
) 
  

[unloading code which was loaded with loadstring]

Yeah that's it though I'd do the following:

  
local loader = {environment = {}} 
function loader:generate_environment () 
    self.environment = _G -- make so that it contains all mta functions, would be a mess to add them all on your own 
    self.environment.outputChatBox = function() end 
    self.environment.addEventHandler = 
        function(name, element, func) 
            -- (...) 
        end 
    -- or either / will not work 
    self.environment = { 
        outputChatBox = function() end, 
        addEventHandler = 
            function() 
            end, 
        triggerServerEvent = function() end, -- avoid server events triggering 
        -- or either 
        triggerServerEvent = function(name, element, ...) return triggerEvent(localPlayer, name, localPlayer, ...) end, -- redirect it towards the client itself 
    } 
    for k, v in pairs(_G) do 
        if k ~= "loader" then -- our loader's 'global'-'environment' 
            self.environment[k] = v 
        end 
    end 
end 
  

Just realized that doing it the second way is not really possible as the for loop would be overwriting your functions. You can instead, would be foolish though, place your functions into another table and then set your environment equal to _G and use a for loop with your functions' table this time instead. However, go through the first way.

You can then simply execute generate_environment each time you want to reset/restart it after, of course, removing and destroying all unnecessary stuff.

[unloading code which was loaded with loadstring]

I guess that your issue might be caused by the fact that you are using addEventHandler when adding your custom events - onScriptLoadRequest, onScriptUnloadRequest. Another reason to use an environment instead. So yeah, either use the wrapper instead (_addEventHandler) or start with the environment thingy.

[unloading code which was loaded with loadstring]

destroyElement is not working there cause when stopSound is executed, (...) the sound element is also destroyed.

Also, may you provide us the full code you're running? I do not see any mistake over here.

[unloading code which was loaded with loadstring]

I suggest also to store all functions and variables into own environment using setfenv.

That basically is what you should do in order to avoid most security issues and in case you want to run all the functions attached to onClientResourceStart, simply set another event name for the handler that you can afterwards manually-trigger in order to execute all those functions simultaneously (without actually triggering onClientResourceStart).

[unloading code which was loaded with loadstring]

Though there are many security-issues related to loading code that way, the one-issue you're going through on your last post is you are not triggering onClientResourceStart, event responsible of executing startMusic function (as, this way, you are not running a resource on its own and thus such event is not being run).

[[HELP] guiCreateEdit color]

You may otherwise have a look at guiSetProperty.

[Create text while resource downloading]

Actually, under onClientDownloadFinish you are, for some reason, using 'player' as if there was any argument expected to arrive - whilst you do not send/specify any when triggering (line 5, uniquely specifying gMe as the event's source). So I guess you instead wanted to use 'client', respective element reference to the player that triggered the event.

Also note that there may be a short timespan between which the 'transferring box' is hidden and then shown up again, same span that might cause your timer to trigger the event that hides your custom messages. So basically, I would recommend you to increase your timer's interval up to 2000ms as specified in the example here.

function onClientDownloadFinish() 
    if textDisplayIsObserver(DownloadDisplay, client) then 
        textDisplayRemoveObserver(DownloadDisplay, client) 
    end 
end 

[dwDraw Moviment]

You can use interpolateBetween or either change the position values manually. Here's an example.
