onPlayerDamage - not triggering.

[ds1-e]

Hey. Why script don't trigger server-side event onPlayerDamage? I decided to try server-side variation of this event.

function onClientPlayerDamage(attacker, weapon, bodypart, loss)
	cancelEvent()
end
addEventHandler("onClientPlayerDamage", getLocalPlayer(), onClientPlayerDamage)

function onPlayerDamage(attacker, weapon, bodypart, loss)
	outputDebugString("y")
end
addEventHandler("onPlayerDamage", getRootElement(), onPlayerDamage)

because the MTA developers decided to consider cancelled events as 'it never happened`.

onPayerDamage is a delayed/streamed version of onClientPlayerDamage

Oh well, so i should with onClientPlayerDamage?

[IIYAMA]

function onClientPlayerDamage(...)
	cancelEvent()
	triggerLatentServerEvent("onPlayerDamage_", localPlayer, ...)
end
addEventHandler("onClientPlayerDamage", getLocalPlayer(), onClientPlayerDamage)

 

addEvent("onPlayerDamage_", true)-- fake event onPlayerDamage_ = security
addEventHandler("onPlayerDamage_", root, 
function (...) 
	triggerEvent("onPlayerDamage", client, ...)
end)

It can be faked, but you might need to figure out a way to reduction data.

For example buffer up till 100 ms, before sending the message

This will reduce a lot in case of fire/minigun/Spraycan/Fire Extinguisher damage: (NOTE: surprisingly the minigun also fires a bullet every frame)

 

How much reduction do you want for that scenario? Do the maths!

local sendingDelay = 100 -- ms
local fps = 60

local timeSlice  = 1000 / fps
local dataReduction = sendingDelay / timeSlice
print("~" .. (dataReduction - 1 ) .. " x times LESS per " .. sendingDelay .. "ms")

That's cool, i'll try it out soon, also with your other solutions for sounds, explosion damage etc., ty  I have used your way to synchronize data from server-side table -> client. For me works well, but until i'll finish my scripts, i am testing stuff alone. I am impatient to test how it will works with players on server

I wanna exclude using elementData in my scripts (atleast in 99%), by creating temporary data system, within tables + trigger/triggerLatent.

By the way as we are in topic about player damage. Using server-side variation of this event should improve hitboxes? Or it's about configuring it here - https://wiki.multitheftauto.com/wiki/Sync_interval_settings

Bullet sync, latency reduction, threadnet, bandwidth_reduction, and also this?

As far as I know these settings are only used for sync element orientations.

 

 

p.s you might also reduce data like this:

function onClientPlayerDamage(attacker, weapon, bodypart, loss)
	local newHealth = getElementHealth(localPlayer)
  
	if newHealth > 0 then -- is not dead
		local oldHealth = newHealth + loss
		setElementHealth(localPlayer, oldHealth) -- reset
	else -- is dead
		cancelEvent()
		triggerLatentServerEvent("onPlayerDamage_", localPlayer, attacker, weapon, bodypart, loss)
	end
end
addEventHandler("onClientPlayerDamage", localPlayer, onClientPlayerDamage)

 

p.s this might also be needed serverside.

addEvent("onPlayerDamage", false) --remote disabled
