[BenceDev]

Hi, i want to disable default automatic trailer attach, but i can attach from bind(bind attach done) so is this posibile to disable or i forget this idea.

You can use the onTrailerAttach event and detach the trailer as soon as this event is triggered. The only downside is you cannot simply cancel the event or detach the trailer immediately, instead you must use a timer that triggers after 50ms for it to be effective.

function detachTrailer(theVehicle)
    local theTrailer = source
    setTimer(function()
        if isElement(theVehicle) and isElement(theTrailer) then
            detachTrailerFromVehicle(theVehicle, theTrailer)
        end
    end, 50, 1)
end
addEventHandler("onTrailerAttach", root, detachTrailer)

Use a table to recognize if the key has been pressed to attach the trailer. if it is pressed it will allow it to attach. If it isnt attached it will detach the trailer.

-- just a table
trailers = {}

-- use this when creating the trailer
trailer = createVehicle ( int model, float x, float y, float z)
trailers[player] = false

-- use this when you press the key
trailers[source] = true

function detachTrailer(theTruck)
if trailers[trailer] == false then
    --detachTrailerFromVehicle(theTruck, source) --detach the newly attached trailer
    -- Immediate detatchment of the trailer through cancel event or this method doesn't seem to work so requires a timer:
    setTimer(detachTrailer2, 50, 1, theTruck, source)
end
addEventHandler("onTrailerAttach", getRootElement(), detachTrailer)

function detachTrailer2(theTruck, trailer)
    if (isElement(theTruck) and isElement(trailer)) then
        detachTrailerFromVehicle(theTruck, trailer)
    end
end

is this client or server side?

Might help if you paste your code here, can't see what you did with the code itself.

seeing the error code i see that you are missing an end within function detachTrailer

function detachTrailer(theTruck)
if trailers[trailer] == false then
    --detachTrailerFromVehicle(theTruck, source) --detach the newly attached trailer
    -- Immediate detatchment of the trailer through cancel event or this method doesn't seem to work so requires a timer:
    setTimer(detachTrailer2, 50, 1, theTruck, source)
end
end
addEventHandler("onTrailerAttach", getRootElement(), detachTrailer)
