[HELP] Get element from a Table?

[TheGrimReaper]

is it possible to get an element from a table by type , for example when i get attached elements to my car , i attached a sound element to my car. but get attached elements returns all the attached elements in to a table ( as i know) , is there a way to get the sound element from the table ???

[MIKI785]

Yeah, simply loop through it and use getElementType. Or you could set the parent of all the attached elements to the vehicle using setElementParent and then simply use getElementsByType utilising the second argument.

When you attach the Sound Element to the Vehicle Element save this into a own table.

 

Example:

local sounds = {}

function attachSoundToVehicle(vehicleElement, soundElement)
	attachElements(vehicleElement, soundElement)
  	sounds[vehicleElement] = soundElement
end

function getVehicleAttachedSound(vehicleElement)
	if isElement(sounds[vehicleElement]) then -- have attached sound
  		return sounds[vehicleElement] -- This is the sound element: sounds[vehicleElement]
 	end
end

ty but will its work when the sound element is attached to more than one vehicle?? ill just post my script here. the problem with it is that when i use stop sound it stops the sound from all vehicles , so i need to get the element from the player vehicle itself so i will just get the sound element on his car. and destroy it to stop the first radio and so on.

end

ignore the function tag() , i didnt clean up this script so it has a lot of useless stuff. so this is how it looks like and from the server side i just call the client side function "change" and dependiing on the number it scrolls through , but the sound doesnt stop at all . and yeah i am not much of a good coder so pls help me out

[Pirulax]

Jesus christ, u use this somewhere?
Please clean the code up a little bit, so we can actually read it, and then understand it.

 

Thanks >D

there you go @Pirulax  , lets see if u can help me

 

[Pirulax]

Its still missing indentations.

Btw, yeah, use this script piece:

local  soundsByVeh = {}

function attachSoundToVehicle(vehicleElement, soundElement)
    attachElements(vehicleElement, soundElement)
    soundsByVeh[vehicleElement][soundElement] = soundElement
end

function getSoundsAttachedToVehicle(veh)
    return soundsByVeh[vehicleElement]
end

function removeAttachedSoundFromVehicle(veh, sound)
    soundsByVeh[vehicleElement][sound] = nil
end
