How to do this?

[MetaGamer]

Well my question is how to return a function value in TriggerClientEvent. For example

client.lua

  
function Example() 
    return "Hey Brown Cow!" 
end 
addEvent("TheExample", true) 
addEventHandler("TheExample", getRootElement(), Example)  
  

server.lua

  
local msg = triggerClientEvent("TheExample", getRootElement()) 
ouputChatBox(tostring(msg)) 
  

The output should be "Hey Brown Cow!" not "true".

That's because it doesn't work that way.

Wiki quote: Returns true if the event trigger has been sent, false if invalid arguments were specified.

Ya I know that. But how to return that string "Hey Brown Cow!" to the server?

[Castillo]

-- client side:

function Example() 
    triggerServerEvent("returnData",localPlayer,"Hey Brown Cow!") 
end 
addEvent("TheExample", true) 
addEventHandler("TheExample", getRootElement(), Example) 

-- server side:

triggerClientEvent("TheExample", getRootElement()) 
  
addEvent("returnData",true) 
addEventHandler("returnData",root, 
function (msg) 
     outputChatBox(tostring(msg)) 
end)

You're welcome .

BTW how to bypass or ignore a function parameter or argument?

[MetaGamer]

plus your code will create an unconditional or never ending loop between the two sides

I got it fixed at last!

The first problem can be fixed using nil

The second problem can be fixed using if\else statement

sorry, but you should have used the "edit" button, instead of making new posts

Yep sorry about that!
