Call functions in other directories?

[tommymaster]

Hi! I know about the "call", and "exports" function, but is there an other way, like in C++, that i can include an other script, from an other directory? As i know "require" is not allowed in MTASA.

You can put <include resource="resname" /> or use fileOpen, fileRead, pcall and loadstring functions.

local fileHandler = fileOpen(":resfolder/otherScript.lua")
if fileHandler then
  local fileContent = fileRead(fileHandler, fileGetSize(fileHandler))
  fileClose(fileHandler)
  pcall(loadstring(fileContent))
end

Why don't you like the exports tho? You can use an event aswell, but things get  bit different there.

--script1.lua
function output()
    print ("ok")
end

--script1 meta.xml
<meta>
    <script src="script1.lua" type="server"/>

    <export function="output"/>
</meta>
  
--script2.lua
output()
  
--script2 meta.xml
<meta>
    <include resource="script1"/>
    <script src="script2.lua" type="server"/>
</meta>

Still does not work.

When you export function and call it in another resource you use those formats:

exports.resname:functionName(arguments)

or

exports["resname"]:functionName(arguments)

Then:

--script1.lua
function output()
    print ("ok")
end

--script1 meta.xml
<meta>
    <script src="script1.lua" type="server"/>

    <export function="output"/>
</meta>
  
--script2.lua
exports.script1:output()
  
--script2 meta.xml
<meta>
    <include resource="script1"/>
    <script src="script2.lua" type="server"/>
</meta>

I think he didn't want to use exports for some reason.

Never tried it myself, but won't dofile or loadfile do the job?

Script 1

<meta>
    <script src="script1.lua" type="server"/>
    <export function="output"/>
</meta>

function output()
    outputChatBox('Exports Confirmed')
end

Script 2

<meta>
    <include resource="script1"/>
    <script src="script2.lua" type="server"/>
</meta>

local e = exports.script1

e:output()

Note that both have to be on the same side, server or client. Exported functions MUST be exported inside the meta of the same script where the function is located.

You can reenable the "require" by loading module in serverside.
