[QUESTION] why onVehicleDamage event doesn't trigger always?

[DriFtyZ]

As the title says onVehicleDamage doesn't register always.. what i mean is i have the following code
 

addEventHandler("onVehicleDamage", getRootElement(),
function(loss)	
	local health = getElementHealth(source) - 250
	local vehHealth = math.floor(health / 750 * 100)
	if vehHealth < 1 then
		setElementHealth(source, 250)
	end
	iprint("vehHealth: ", vehHealth)
end)

i have set the vehicle health showing as an integer from 1 to 100 and when it reaches below 0 it caughts in fire but when the vehicle is 0 and caughts up in fire sometimes the event works and restores the health to 250 which is 0(before it caught in fire) and sometimes not and the vehicle explodes. Does anybody knows why this happens

I had this problem before, it seems that event doesn't trigger when player attack that vehicle, so you need to use onClientVehicleDamage.

That has probably to do with the bandwidth saving (and maybe also finding it hard to decide which player should sync the vehicle).

onClientVehicleDamage seems to be more accurate but theres one thing that confuses and it happend on both events when the vehicle is 100 and hits a wall for first time it doesn't get his health and i have to hit again to start decreasing it(in script)

[IIYAMA]

local damageTimeCount = 0
addEventHandler("onVehicleDamage", getRootElement(),
function(loss)
	damageTimeCount = damageTimeCount+1
	local health = getElementHealth(source) - 250
	local vehHealth = math.floor(health / 750 * 100)
	if vehHealth < 1 then
		setElementHealth(source, 250)
	end
	iprint("damageTimeCount: " .. damageTimeCount .. ", vehHealth 1: ", vehHealth)
	setTimer(function (vehicle, damageTimeCount)
		local health = getElementHealth(vehicle) - 250
		local vehHealth = math.floor(health / 750 * 100)
		iprint("damageTimeCount: " .. damageTimeCount .. ", vehHealth 2: ", vehHealth)
	end, 50, 1, source, damageTimeCount)
end)

What is the result when you use this code?

vehHealth 2 on iprint is correct, wait imma modify this into a client side function i did before

works like a charm right now, in speedometer it always show current health because its getting refreshed in every HUD rendered frame but in script it just stayed 1 health variable behind and seems the 50ms delay gets it fixed

-- Sync vehicle damage from client to server
local damageTimeCount = 0

addEventHandler("onClientVehicleDamage", getRootElement(),
function(attacker, weapon, loss, x, y, z, tyre)	
	damageTimeCount = damageTimeCount + 1
	if attacker or weapon then
		cancelEvent()
	end
	local vehElement = source
	local vehPlate = getVehiclePlateText(source)
	local player = getElementData(source, "player")
	
	setTimer(function (vehicle, damageTimeCount)
		local health = getElementHealth(vehicle) - 250
		local vehHealth = math.floor(health / 750 * 100)
		iprint("damageTimeCount: " .. damageTimeCount .. ", vehHealth 2: ", vehHealth)
		triggerServerEvent("healthToDb", getRootElement(), vehHealth, vehElement, vehPlate, player)
	end, 50, 1, source, damageTimeCount)
end)
