[NEED HELP] How to trigger a vehicle? Read to understand

lilwayn · September 17, 2023

I'm confused about something, how to add the vehicle in the event handler argument when the vehicle is created inside another function? Cause whenever I type the vehicle’s variable name, it returns that it doesnt exist.

vehicle variable must be global

Give us your code so we can help you better

1. Create a new .lua file
2. Open meta and type <script src="yourfile.lua" type="shared" />

It will look like this
Shared File:

my_var = "test"

Server File:

addCommandHandler("s", function(p, c)
    outputChatBox(my_var, root, 255, 255, 255, true)
end)

Client File:

addCommandHandler("c", function()
    outputChatBox(my_var)
end)

I hope this is what you mean

Hello, i've tried your idea. When i printed the variable in server, it worked completely fine, but in client it doesnt seem to be working as everytime i try printing it keeps giving me a 0

I've added this in shared.lua

plantedBombs = 0

this in server.lua

function onHit(player)
    if (#m > 0 and #b > 0) then
        destroyElement(m[1])
        destroyElement(b[1])
        table.remove(m, 1)
        table.remove(b, 1)
    end
    for i, k in ipairs(Bomb2) do
		if (isElementAttached(Bomb2[i])) then
			detachElements(Bomb2[i], helic[1])
			plantedBombs = plantedBombs + 1
			outputChatBox("Bomb has been successfully installed, Do the same with the rest!", root, 34, 139, 34)
			outputChatBox(plantedBombs) ---- This returns what it should return
		end
    end
	if (plantedBombs == 5) then
		triggerEvent("stopMission", root, onHit)
		givePlayerMoney(player, 50000)
		outputChatBox("Congratulations, you have passed the mission and got $50,000 as a reward!", root, 34, 139, 34)
	end
end

This in client.lua

function renderTimer()
	local white = tocolor(255, 255, 255, 255)
	if (isTimer(startTimer)) then
		local remaining = getTimerDetails(startTimer)
		local remaining = remaining / 1000
		outputChatBox(plantedBombs) ---- Keeps printing a zero
		dxDrawText("Delievered Bombs : "..plantedBombs.."", 1162, 654, screenW, 711, white, 1.3, "default-bold", "right", "bottom")
		dxDrawText("Time Remaining : "..math.floor(remaining / 60)..":"..math.floor(remaining % 60).."", 1228, 725, screenW, 740, white, 1.3, "default-bold", "right", "bottom")
	end
end

Any solution?

trigging in the for is not the most appropriate, the best would be outside the for

    for i, k in ipairs(Bomb2) do
        if (isElementAttached(Bomb2[i])) then
            detachElements(Bomb2[i], helic[1])

        end
    end

Hello thank you guys for assisting me, it's now working

Sorry for being a bit inquirer. I'm facing another thing, i did find a solution for it tho but it's not very good. Lemme show you

local helic = {}

function startM()
	if (not isElement(source) and getElementType(source) == "player") then
		return false
	end
	if (not isPedInVehicle(source)) then
		return false
	end
	local heli = createVehicle(501, 2625.53247, 733.39642, 10.82031)
	table.insert(helic, heli)
	warpPedIntoVehicle(source, heli)
	setElementAlpha(source, 0)
	bindKey(source, "h", "down", attachBomb)
	for i, k in ipairs(Bombs) do
		Bomb1[i] = createObject(1654, Bombs[i][1], Bombs[i][2], Bombs[i][3] - 0.5)
		Bomb2[i] = Bomb1[i]
		setElementCollisionsEnabled(Bomb1[i], false)
	end
	addEventHandler("onVehicleExit", heli, onExit)
	---triggerClientEvent(source, "clientPed", source, startM)
end
addEvent("startMission", true)
addEventHandler("startMission", root, startM)


function onHit(player)
    if (#m > 0 and #b > 0) then
        destroyElement(m[1])
        destroyElement(b[1])
        table.remove(m, 1)
        table.remove(b, 1)
    end
	if (not helic[1]) then
		return false
	end
	local lmnt = getAttachedElements(helic[1])
	if (not lmnt) then
		return false
	end
	for i, k in ipairs(lmnt) do
		if (getElementType(lmnt[i]) == "object" and isElementAttached(lmnt[i])) then
            detachElements(lmnt[i], helic[1])
            plantedBombs = plantedBombs + 1
			if (plantedBombs == 1) then
				outputChatBox("Congratulations, you have passed the mission and got $50,000 as a reward!", root, 34, 139, 34)
			else
				outputChatBox("Bomb has been successfully installed, Do the same with the rest!", root, 34, 139, 34)
				outputChatBox(plantedBombs)
			end
        end
    end
	triggerClientEvent(player, "updatePlantedBombs", root, plantedBombs)
	if (plantedBombs == 1) then
        triggerEvent("stopMission", root, onHit)
		triggerClientEvent(resourceRoot, "stopM", resourceRoot, onHit)
    end
end

I've created a vehicle inside a function, if i knew from the start how to use the variable in other functions when it's inside a function, i wouldn't add it inside a table, i wanna use sometimes the vehicle is client but sadly i couldn't. Can anyone tell me what should i exactly do (Please dont tell me to put the variable global, as i dont want to cause setting it as global will create the vehicle once when the resource start and i dont wanna that)

Also, the getAttachedElements(helic[1]) is sending a warning saying that it requires an argument. i guess it's because i'm using helic[1] as an argument.

Help me, please. i'm new into lua and i wanna create my first working script

use the variable globally, this does not mean that you place it outside the function, just delete "local"

I’ve tried already, but it says always in the addEventHandler that it requires an element and it got nil
