[HELP] onPickupHit event

[..:D&G:..]

Hi, I am trying to make a function that opens a client side window when the player hits a pickup

function pickupShowGarageGUI(thePlayer) 
    showGarageGUI() 
end 
addEventHandler ( "onPickupHit", pickup, pickupShowGarageGUI ) 

There is the function, and the pickup is in another function but same file (server side):

pickup = createPickup ( x+4.40, y+4, z-1, 3, 1277, 0, 0 ) 

I keep getting that error, which says that an element is expected at argument 2 ("pickup") and got nil, but the pickup exists...

Maybe you are creating pickup after attaching event to function? I mean pickup's function is created earlier than pickup.

[..:D&G:..]

Yes it is. The pickup's function is on top of the onPickupHit function.

[WhoAmI]

Pickup has to be created before you attach it to onPickupHit event.

[..:D&G:..]

It is, as I said, the function that creates the pickup is ON TOP of that function with onPickupHit. Also I have not local'ed it. The function that creates the pickup has the onResourceStart event, maybe that interferes with the other function/event?

[WhoAmI]

Move pickup creation from onResourceStart. Make it without any event - put it on top of code.

[..:D&G:..]

I can't really put the line on top of the code, cuz it's getting the coordinates from a MySQL table:

pickup = createPickup ( x+4.40, y+4, z-1, 3, 1277, 0, 0 ) 

Is there other way of doing it?

[WhoAmI]

It is.

function pickupShowGarageGUI(thePlayer) 
    if ( source ~= pickup ) then return end 
    showGarageGUI() 
end 
addEventHandler ( "onPickupHit", resourceRoot, pickupShowGarageGUI ) 

[..:D&G:..]

That doesn't work at all. It is like the event is not even there

can you post your full code?

function spawnGaragesOnStart( res ) 
     
    local result = mysqli:query("SELECT x, y, z, interior, dimension FROM garages") 
    while true do 
        local row = mysqli:fetch_assoc(result) 
        if not (row) then break end

Try this :

function pickupShowGarageGUI(thePlayer) 
  if ( source ~= pickup ) then return end 
    triggerClientEvent ( thePlayer, "showGarageUI", thePlayer ) 
end 
  
  
function spawnGaragesOnStart( res ) 
    
    local result = mysqli:query("SELECT x, y, z, interior, dimension FROM garages") 
    while true do 
        local row = mysqli:fetch_assoc(result) 
        if not (row) then break end 
        
        local x = row['x'] 
        local y = row['y'] 
        local z = row['z'] 
        local int = row['interior'] 
        local dim = row['dimension'] 
        
        pickup = createPickup ( x+4.40, y+4, z-1, 3, 1277, 0, 0 ) 
        setElementData(garage, "pickup", pickup) 
        
        setElementInterior(pickup, tonumber(int)) 
        setElementDimension(pickup, tonumber(dim)) 
        addEventHandler ( "onPickupHit", pickup, pickupShowGarageGUI ) 
    end 
  
    mysqli:free_result(result)  
end 
addEventHandler("onResourceStart", resourceRoot, spawnGaragesOnStart)

Still nothing..

function pickupShowGarageGUI(thePlayer) 
    outputChatBox("Working fine",thePlayer) 
    triggerClientEvent ( thePlayer, "showGarageUI", thePlayer ) 
end 

[..:D&G:..]

Nope, it still says that an element is expected at argument 2 for the event onPickupHit. I tried creating a separate pickup on top of that function (outside any functions) and it works. For some reasons it doesn't get the pickup from the first function

I even tried this:

function pickupShowGarageGUI(thePlayer) 
    for i, v in ipairs (getElementsByType("object")) do 
        if (getElementModel(v) == 17950) then 
            pickup = getElementData(v, "pickup") 
            outputChatBox("Working fine",thePlayer) 
            triggerClientEvent ( thePlayer, "showGarageUI", thePlayer ) 
        end 
    end 
end 
addEventHandler ( "onPickupHit", pickup, pickupShowGarageGUI ) 

The pickup is attached to a garage, but it still says that there is no element at argument 2

[Walid]

Try to attach ' ColSphere' createColSphere() to the pickup then use onColShipHit.

more than that garage it's not defined here :

setElementData(garage, "pickup", pickup)

setElementData(garage, "pickup", pickup) 

It still outputs the same error.

Garage is defined, but I deleted half the function, to only leave the things that relate to my problem..

show me your code
