How to detect vehicle's HP?

[Hiding]

Hello, my question is how to detect if my vehicle's health is reaching 0? if so then write in the chat that "your vehicle's HP is 0".

onVehicleDamage
getElementHealth

I tried with onClientVehicleDamage, but it only triggered when my car was exploded. I need the localPlayer vehicle's health before the explosion.

the event triggers because u dont use the loss parameter to check the amount of health the vehicle lost in onClientVehicleDamage 

 

addEventHandler("onClientVehicleDamage", root,
    function(loss)
        local vehHP = getElementHealth(source)
        if currentHealth - loss <= 0 then
        end
    end)

you can get the pilot with getVehicleOccupant function and check if it exists

an example that maybe can help you

function VehicleHealth(attacker, weapon, loss)
    local HealthOfVehicle = getElementHealth(source)
    local driver = getVehicleOccupant(source)
    if driver then
        outputChatBox("life before the crash: "..math.floor(HealthOfVehicle))
        outputChatBox("life after the crash: "..math.floor(HealthOfVehicle - loss))
        outputChatBox("damage taken: "..math.floor(loss))
    end
end
addEventHandler("onClientVehicleDamage", root, VehicleHealth)

Thank you guys so much for trying to help me, but I guess you don't get it  maybe I have to check with onClientRender when the HP reaches 0, because this onClientVehicleDamage is only triggering if damage happens, but for example when the vehicle is upside down and starts burning, it doesn't actually suffer any damage until it explodes and its life reaches zero. So what I would need is that as soon as the vehicle reaches zero hp output to the chat that "vehicle hp is 0" or something. But if I check it with onClientRender then it will flood the chat until my hp is 0, how can I manage to write once in the chat if the hp is reaching 0?

Hi

 

I noticed that :

- The vehicle starts to be on fire below 250 / 1000

- When it's flipped it takes 1100 of damage during the explosion

I don't see any event about detecting the vehicle on fire but you can still detect it like this :
    
 

addEventHandler("onClientVehicleEnter", root, function() 
	local vehicle = source
	setTimer(function()
		if getElementHealth(vehicle) < 250 then
			print("onFire")
			killTimer(sourceTimer)
		end
	end, 500, 0)
	
end)

local msg = false

function checkVehHealth()
    local veh = getPedOccupiedVehicle(localPlayer)
    
    if veh then
        local currHealth = getElementHealth(veh)

        if currHealth <= 0 and not msg then
            outputChatBox("Your vehicle HP is 0", 255, 0, 0)
            msg = true
        elseif currHealth > 0 then
            msg = false
        end
    end
end

addEventHandler("onClientRender", root, checkVehHealth)

u can use a boolean variable to ensure the message is only displayed once
