Setting an object in elementData

[..:D&G:..]

Hello guys, I'm trying to make a mechanic job where the car parts are picked up by the player. When the mechanic enters a marker, the part should attach to the player, and if he enters again and already has a car part attached to them, the object should get destroyed, but it doesn't really work... The object is attached to the player, but it doesn't get destroyed due to the elementData...

parts =  
    { 
        [1015] = { } 
    }  
  
function attachCarPart(hitElement, partID)  
    if (tonumber(getElementData(hitElement, "partInHand")) > 0) then 
        local IDpart = tonumber(getElementData(hitElement, "partInHand")) 
        destroyElement(parts[IDpart][hitElement]) 
        parts[IDpart][hitElement] = nil 
        setElementData(hitElement, "partInHand", 0) 
    else 
        parts[partID][hitElement] = part 
        part = createObject(partID, 0, 0, 0) 
        setElementData(hitElement, "partInHand", partID) 
    end 
end

That is because your value in the table is nil. You set nil to your table 'parts' and then you're trying to destroy it. Check which values return your variables and use debugscript.

Not really because all that is triggered here:

function onMechanicHitMarker( hitElement, piesaID )  
        attachCarPart(hitElement, 1081) 
end 
addEventHandler( "onMarkerHit", mechanicMarker, onMechanicHitMarker )

    parts = 
        { 
            [1015] = { } 
        } 
      
    function attachCarPart(hitElement, partID) 
        if (tonumber(getElementData(hitElement, "partInHand")) > 0) then 
            local IDpart = tonumber(getElementData(hitElement, "partInHand")) 
            destroyElement(parts[IDpart][hitElement]) 
            parts[IDpart][hitElement] = nil 
            setElementData(hitElement, "partInHand", 0) 
        else 
            part = createObject(partID, 0, 0, 0) 
            parts[partID][hitElement] = part 
            setElementData(hitElement, "partInHand", partID) 
        end 
    end

Can you tell me what you've changed?

See lines 13 and 14 in my code and in yours.

So it was all just the order of the code....? -.-

That's not just an order. That's a logical order. Like I said you set an empty variable to your table and only after that you defined it.
