    Hi there, interested in scripting and debugging?

    Read the story below! ?

     

     

    Today I was testing a resource that I have been working on for the last 2 days. It is a resource for creating 'fires' as element. Used for fixing a lot of issues with 'fire' in general, good for zombie/coop, pvp and roleplay gamemodes. (will be public...)

    Anyway, this post is not about the resource. It is about a way you could check your resource for unwanted function calls.

     

    Back to the story.

    So I opened the network stats window. (/shownetstat)

    I noticed that the data rate going out was incredible high. (This is how much data my MTA client is sending to the server) The zombie resource was also using a lot of the network, but I could notice the difference.

    Unfortunately I wasn't sure which part was causing it. ?

     

    So I started writing a function wrapper. There is also the https://wiki.multitheftauto.com/wiki/AddDebugHook but I was a bit too lazy to test it out. So I went for the simple wrapper. The function that I had to check was 'triggerServerEvent'. Because this one is most likely the one responsible for the high out going network usage. 

    do
	-- Save the original triggerServerEvent reference
	local triggerServerEvent_ = triggerServerEvent
	
	function triggerServerEvent (...)
		return triggerServerEvent_(...)
	end
end

     

    Now I had to collect some of the results. First step was to define some of the variables that are used to store the results.

    Spoiler 
    -- Define all required variables
local triggerServerEventCount = 0 -- How many times the function is called
local triggerServerEventByEvent = {} -- Which event and from where + how many times
local debugInfo = ""

     

     

    Grouping and counting the results is also very important:

    Spoiler 
    local arg = {...}

--[[

Group by the function calls by 'event' and call location

]]
local groupByKey = arg[1] .. " > Line: " ..  debug.getinfo(2).currentline  .. " "
triggerServerEventByEvent[groupByKey] = (triggerServerEventByEvent[groupByKey]  or 0) + 1

--[[

Increase the function execution counter

]]
triggerServerEventCount = triggerServerEventCount + 1

     

     

    And the last step was to display, update and reset the collected results every 1 second.

    Spoiler 
    addEventHandler("onClientRender", root, 
  function () 
    --[[

    Display information

    ]]
    dxDrawText(debugInfo, 30, 300)
  end)

setTimer(function () 
    --[[

    Update the display information

    ]]
    debugInfo = "triggerServerEventCount: " .. triggerServerEventCount .. " > " .. inspect(triggerServerEventByEvent) .. "\n\n"
    triggerServerEventCount = 0
    triggerServerEventByEvent = {}
  end, 1000, 0)

     

     

    And here is more or less the result (screenshot & code). Could be improved by also adding the filename, but this is was good enough for this resource.

    Spoiler 
    
do
	-- Save the original triggerServerEvent reference
	local triggerServerEvent_ = triggerServerEvent


	-- Define all required variables
	local triggerServerEventCount = 0 -- How many times the function is called
	local triggerServerEventByEvent = {} -- Which event and from where
	local debugInfo = ""

	addEventHandler("onClientRender", root, 
	function () 
		--[[

			Display information

		]]
		dxDrawText(debugInfo, 30, 300)
	end)

	setTimer(function () 
		--[[

			Update the display information

		]]
		debugInfo = "triggerServerEventCount: " .. triggerServerEventCount .. " > " .. inspect(triggerServerEventByEvent) .. "\n\n"
		triggerServerEventCount = 0
		triggerServerEventByEvent = {}
	end, 1000, 0)

	function triggerServerEvent (...)
		local arg = {...}

		--[[

			Group by the function calls by 'event' and call location

		]]
		local groupByKey = arg[1] .. " > Line: " ..  debug.getinfo(2).currentline  .. " "
		triggerServerEventByEvent[groupByKey] = (triggerServerEventByEvent[groupByKey]  or 0) + 1

		--[[

			Increase the function execution counter

		]]
		triggerServerEventCount = triggerServerEventCount + 1

		--[[

			Resume the normal behaviour of the function:

		]]
		return triggerServerEvent_(...)
	end
end
