setElementData + tables + functions

[Bonsai]

Hey there,

I got a little problem using tables that contain functions as element data.

According to the wiki you can't use functions for that.

I have one file that contains something with this structure:

function Test.new(name) 
  
    local self = {}; 
     
    self.element = createElement("Test", name) 
     
    function self.destroy() 
  
        destroyElement(self.element) 
        outputDebugString("Destroyed") 
         
    end  
     
    setElementData(self.element, "object", self) 
    return self 
     
end 

Then I have another file that that contains a function that is triggered at some point:

function test() 
  
    local testObject = getElementData(source, "object") 
    testObject.destroy() 
     
end 

The problem is that I can't access the "destroy" function like this.

Does anyone know a solution for this?

The only thing I can think of is using a global table containing the object, which isn't that nice.

function newElement(name) 
    local countID = 0 
    while getElementByID(name, countID) do 
        countID = countID + 1 
    end 
    local self = {} 
    self.element = createElement("Test", name) 
    self.destroy = "destroyElement(getElementByID('" .. name .. "', " .. tostring(countID) .."));outputChatBox('Destroyed it!')" 
    setElementData(localPlayer, "object", self) 
    return self 
end 
  
function testDestroy() 
    local testObject = loadstring(getElementData(localPlayer, "object").destroy)() 
end 
  
newElement("test") 
testDestroy() 

Maybe something like this would suffice your needs?

That seems to be a working solution, but I'm not sure if its a good idea doing it like that.

I also tried using string.dump to save the function and execute it later but MTA won't let me execute it:

Bad usage @ 'loadstring' [argument 1 is invalid. Please re-compile at https://luac.multitheftauto.com/]

Anyway, I might have to go with a global table then

Why don't you use loadstring(str), and save the string with setElementData?

Meanwhile I found a much easier and better solution.

I simply attached an event to that function and element.

No idea why I didn't think about that earlier.

Its working fine now.
