Sorry, last pic was token badly, basically what I want to do is to make an ammunition with cart system, when you check out you pay the total money and get all the weapon you got in your cart, please help, I'm stuck here for long time

Hey guys! So I want to retrieve the world time from internet, and then show them in my server, is this possible? I have checked on google but I got confused, any pro on lua, please help, thank you very much!

Hey JR10, thank you for your help again, now it's partly working, but the big problem remains. What I'm trying to do is, to make a ammunation system with cart like this It should take the total money from player and give the player weapons he bought that was in the cart Thank you again

I read on the wiki, that "while" loops the function when it meet the circumstance that follows it

Hey, the gridlist is a cart, when the player press buy button, we need to give him the weapons in the cart and take his money

So I'm trying to make a script for ammunation using gridlist and saving values in tables, I wrote this script, when I test it my computer dies, please help to check where's wrong weapontable = { } ammotable = { } pricetable = { } function table.size(tab) local length = 0 for _ in pairs(tab) do length = length + 1 end return length end addEventHandler("onClientResourceStart", resourceRoot,

I see, thank you very much

I have put the functions to load the mod

function download(resource) if resource == getThisResource() then outputChatBox("Download started") downloadFile("rhino.txd") downloadFile("rhino.dff") end end addEventHandler("onClientResourceStart",getRootElement(),download) function replacemod(success) if success == true then local txd = engineLoadTXD ( "rhino.txd" ) local dff = engineLoadDFF ( "rhino.dff", 432 ) engineImportTXD ( txd, 432 ) engineReplaceModel ( dff, 432 ) else outputChatBox("Download was failed") end end addEventHandler("onClientFileDownloadComplete",getRootElement(),replacemod) This is the full code

I used outputChatbox to see and it says it's failed

Please help guys

Yeah, I guess i should use variables and thank you

Too bad you didn't include that line, or edited the apparent error message, since it looks like it originates from line 28, not 46.http://www.lua.org/manual/5.1/manual.ht ... math.atan2 math.atan2 has two arguments, not just one. math.atan2 ((copx - prisonerx) / (copy - prisonery)) --extract of line 28 I have deleted some part of the scripts before i post it here, i will try out your fix later, thank you

I am making a script for ammunation, and I want to also make a cart for the ammunation. I made a gridlist for cart, and a buy button. Is there any way to make it like, when I press "Buy" and then i buy every item in the cart? And is there anyway to make it like, if there is already this kind of ammo in the cart, it won't create another row for these ammo, but will combine with the other same type of ammo?
