use destroyElement

type
 

destroyElement (element)

example:
let's assume that the created blip is called BlipCarro, then insert the function to execute when the player enters the car
 

 destroyElement (BlipCarro)

but blip is created only when a player gets into the transport stream zone, then blip is created, and I want to make sure that blip is not created if the player is in the car, and if the transport is already in the player's stream zone and another player got into the car, blip was deleted

Just now, Ihnify said:

mas o blip é criado apenas quando um jogador entra na zona de fluxo de transporte, então o blip é criado, e eu quero ter certeza de que o blip não seja criado se o jogador estiver no carro e se o transporte já estiver na zona de fluxo do jogador e outro jogador entrou no carro, o blip foi excluído

post your script for more help...

• Server created elements are available clientside.
• Client created elements are NOT available on serverside.

 

But there is 1 trick you can use to delete clientside elements by serverside.

Start the following example when you are not downloading other resources, clientside must have been started before 10 seconds.

 

Server

local serverSideElement = createElement("exampleElement", "id:3563454hasduy3685dsfs") 


setTimer(function () -- destroy the element over 10 seconds
	destroyElement(serverSideElement)
end, 10000, 1)

 

Client

local clientSideElement = createElement("exampleExample")


-- get the serverside element
local serverSideElement = getElementByID("id:3563454hasduy3685dsfs")
if isElement(serverSideElement) then
	setElementParent(clientSideElement, serverSideElement) -- set the clientside element as child of the serverside element
end


addEventHandler("onClientElementDestroy", clientSideElement, 
function () 
  iprint("onClientElementDestroy")
end, false)

 

***

Fixed the wrong ID value.

this client side 

local vehicleBlipRoot = createElement("vehicleBlipRoot", "vehicleBlipRoot")

local function streamIn()
	if getElementType(source) ~= "vehicle" then
		return
	end
	
	for _, blip in ipairs(getElementChildren(vehicleBlipRoot)) do
		if getElementAttachedTo(blip) == source then
			return
		end
	end

	if source == getPedOccupiedVehicle(localPlayer) then
		return
	end

	local blip = createBlipAttachedTo(source, 0, 1, 150, 150, 150, 255, 1)
	setElementParent(blip, vehicleBlipRoot)
end
addEventHandler("onClientElementStreamIn", root, streamIn)

local function streamOut()
	if getElementType(source) ~= "vehicle" then
		return
    end
	
    for _, blip in ipairs(getElementChildren(vehicleBlipRoot)) do
		if getElementAttachedTo(blip) == source then
			destroyElement(blip)
			break
		end
	end
end
addEventHandler("onClientElementStreamOut", root, streamOut)

Exactly, that is why I gave you an example of how to do that, don't waste it.

Since you still do not understand it, this is my last attempt to show you how you can delete clientside elements by also using a serverside element. If you still don't understand it, then that is unfortunately.

 

Serverside

local playerBlipElementContainerElement = createElement("playerBlipElementContainer", "playerBlipElementContainer:24436dg45632Ddfg") 

addEventHandler("onPlayerJoin", root, 
function () 
	local serverSideElement = createElement("playerBlipElement_serverSide") 
	setElementData(serverSideElement, "owner", source)
	setElementParent(serverSideElement, playerBlipElementContainerElement)
end)

--[[ 
-- Players already ingame
addEventHandler("onClientResourceStart"... getElementsByType("player") ...

]]

 

Clientside

local playerBlipElementContainerElement = getElementByID("playerBlipElementContainer:24436dg45632Ddfg")


-------------------
-- MODIFY THIS, for players already ingame (add a little delay) and for new players (onClientPlayerJoin + add a little delay)

local serverSideElements = getElementChildren(playerBlipElementContainerElement)
for i=1, #serverSideElements do
	local serverSideElement = serverSideElements[i]
	local owner = getElementData(serverSideElement, "owner")
	local blip = createBlipAttachedTo(owner, 0, 1, 150, 150, 150, 255, 1)
  
	setElementParent(blip, serverSideElement)
end

Sorry, but I didn't understand I'm really stupid, you can use an example with creating a blip for an vehicle, and deleting it on the server, please, if it's not difficult

You are not stupid, it might be too complex to begin with.

 

This is called the element tree:

https://wiki.multitheftauto.com/wiki/Element_tree

 

And as you know, tree's do start with the root element. (With this tree, there is a single root, yea I know that is strange...)

 

Under this (inverted) tree you can see it is branching in to different other elements.

This is how MTA organize it's elements.

• resourceRoot is the start of a single resource.
• Under the resourceRoot, you can see 1 resourceDynamicElementRoot. (This is where all your elements created by script are childs of)
• There are also resourceMapRootElement(s). Each element represents a map element, created by a .map file.

 

---

 

Knowing all this and look at this representation of your resource (based on the code above):

 

Serverside

<resource id="your-resource"> <!-- resourceRoot -->
  <map id="dynamic"> <!-- resourceDynamicElementRoot -->
  </map>
</resource>

 

Clientside

<resource id="your-resource"> <!-- (serverside) resourceRoot -->
	<map id="dynamic"> <!-- (serverside) resourceDynamicElementRoot -->

<!-- START clientside -->
		<vehicleBlipRoot>
			<blip/>  
			<blip/>  
			<blip/>  
		</vehicleBlipRoot>
<!-- END clientside -->

	</map> <!-- (serverside) -->
</resource> <!-- (serverside) -->

 

As I said before, clientside has access to all serverside elements. But serverside has no access/isn't ware of clientside elements.

 

---

 

You want to destroy client elements with serverside, but serverside is not ware that they exist. With the following element structure you can solve that:

<resource id="your-resource">
	<map id="dynamic">
		<vehicleBlipRoot>

			<blipServerSide>
				<!-- START clientside -->
				<blip/>  
				<!-- END clientside -->
			</blipServerSide> 

			<blipServerSide>
				<!-- START clientside -->
				<blip/>  
				<!-- END clientside -->
			</blipServerSide> 
          
			<blipServerSide>
				<!-- START clientside -->
				<blip/>  
				<!-- END clientside -->
			</blipServerSide> 

		</vehicleBlipRoot>
	</map>
</resource>

 

If you delete blipServerSide, with the function destroyElement, then the blip clientside will also be deleted.

1. This is happening because when you call the destroyElement function on serverside, the same function will be called on clientside on the same element (behind the scenes).
2. And thx to propagation (already enabled) the function will also be called for all the children of the element that is about to be destroyed, which is in this case the client element blip.

 

 

I can't explain it better than this.
