fileOpen while downloadFile

[XJMLN]

Hi, 

I tried to use fileOpen (c-side) when downloadFile is started, but it doesn't work in db3: Bad usage @ 'fileOpen' [unable to load file 'dff/vehicles/542.dff'] etc. but file is in this dir.

Someone maybe know where problem is?  

 

function replac_getAllSize(d)
    local size = 0  
    for i,v in ipairs(d) do 
        local t 
        local t2
        if v[2] == 1 then 
            t = "txd/vehicles/"..v[1]..".txd"
            t2 = "dff/vehicles/"..v[1]..".dff"
        elseif v[2] == 2 then
            t = "txd/skins/"..v[1]..".txd"
            t2 = "dff/skins/"..v[1]..".dff"
        end
        if fileExists(t2) then
            local openFile = fileOpen(t2,true)
            if openFile then 
                size = size + fileGetSize(openFile)
                fileClose(openFile)
            else 
            end
        else
        end
        if fileExists(t) then 
            local openFile2 = fileOpen(t,true) 
            if openFile2 then 
                size = size + fileGetSize(openFile2)
                fileClose(openFile2)
            else 
            end
        else
        end
    end
    return size/1048576 
end



function calcProg(w, p)
    if w and p then 
        local w = w -2 
        local width = ((w*p)/100)
        return width 
    end
    return 0 
end

    dxDrawRectangle(230, 517, 350, 25, tocolor(255, 255, 255, 255), false)
    local progress = ((size*100)/r.sizeAll)
    local x,y,w,h = (230/800)*sw, (517/600)*sh, (350/800)*sw, (25/600)*sh 
    local width = calcProg(w,progress)
    dxDrawRectangle(x,y,width,h, tocolor(104, 215, 89, 255), false)
    dxDrawText("Trwa pobieranie "..string.format("%.02f",size).."MB/"..string.format("%.02f",r.sizeAll).."MB.. ("..math.floor(progress).."%)", 230, 517, 580, 542, tocolor(0, 0, 0, 254), 1.00, "clear", "center", "center", false, false, false, false, false)
end

function replac_applyChanges(installed,uninstalled)
    r.rendered = true 
    r.sizeAll = 0
    for i,v in ipairs(installed) do
        if v[2] == 1 then 
            t = "vehicles"
        elseif v[2] == 2 then
            t = "skins"
        end
        r.sizeAll = r.sizeAll + v[3]
        local txd = downloadFile("txd/"..t.."/"..v[1]..".txd")
        local dff = downloadFile("dff/"..t.."/"..v[1]..".dff")
    end
    r.installed = installed 
    addEventHandler("onClientRender",root,replac_render)
end

Why do you want to open the TXDs and DFFs?

[XJMLN]

Really? Just look in the code, lol but ok, I must open file to get the actual size of it. 

[NeXuS™]

Try renaming it to .txt and opening it. I don't know if it's going to work.

[XJMLN]

I can't rename file while downloading it in the same time

Give me 10 minutes to test a way.

So the only way I could work around is creating a server-sided script. On startUp calculating the filesizes, saving it into a variable. Then whenever the client joins, the client-side requests that variable (via events). If you need an example of the script.

local fileList = {"test.dff"}
local allSizes = 0

function calcAll()
	for i, k in pairs(fileList) do
		if fileExists(k) then
			allSizes = allSizes + fileGetSize(fileOpen(k))
		end
	end
end
calcAll()

function requestAll(requestClient)
	triggerClientEvent(requestClient, "startDownload", root, allSizes)
end
addEvent("requestSize", true)
addEventHandler("requestSize", root, requestAll)

local fileList = {"test.dff"}

function startDownload(fileSizes)
	outputChatBox("All size: " .. fileSizes)
	for i, k in pairs(fileList) do
		downloadFile(k)
	end
end
addEvent("startDownload", true)
addEventHandler("startDownload", root, startDownload)

triggerServerEvent("requestSize", root, localPlayer)

Yup, i use that version to get size of file on server , but now i need size from client file to show something like 60MB/120MB (50%). It's something weird because i use (probably) the same method from this resource and in that resource it works perfectly..

What you could do is: Using the onClientFileDownloadComplete event, creating an average download speed, and using that to determine how long it'll take to download the next files. (After the first file downloaded the progress would jump from 0MB to xMB, but thats the only way I can think now.)

I can't do anything with that it's caused by that: https://bugs.mtasa.com/view.php?id=3168  

 

Close please.
