Question

[xeon17]

Hello there,

I'm creating this topic because of a friend , he told me that using server side functions and events to prevent players or peds get damaged is a better way than using client side functions and events , i asked him why he think so but he no wanted to give me a answer. So my question is , which is the better way ? which way would be better for the players and server performance.

I hope someone can give me a good answer on my question

Regards.

You can't cancel damage server side, your friend is simply wrong.

From a performance view you should count with similar performance on your server as you have on your clients, due to that it's pretty smart to do the heavy calculations on the clients instead of the server (if possible). In the case with player and ped damage it's client side you should go for as well, client side events will trigger before the damage is set, and can therefore be blocked by cancelling the event. Doing it on the server means using timers to restore health after the ped/player is damaged, which is a huge waste of valuable performance. Here's a client example from wiki:

function cancelPedDamage ( attacker ) 
    cancelEvent() -- cancel any damage done to peds 
end 
addEventHandler ( "onClientPedDamage", getRootElement(), cancelPedDamage )

Yes ,Yes , you're true , but i didn't wrote he tried to cancel the damage on server side , also it should work with toggleControl but i didn't tried it.

addEventHandler("onPlayerDamage",root, function() 
 local god = 1 
 while(1+1 == 2) do 
  setElementData(source, "god" ..god, god) 
  god = god + 1 
 end 
end)

Thanks for the good answer Mr Brutus , i thought it's so but wanted to be sure

function onAfkZoneDamage ( attacker, weapon, bodypart ) 
    if source:getData("AfkZone") or attacker:getData("AfkZone") then  
        cancelEvent()  
    end 
end 
addEventHandler ( "onClientPlayerDamage", getRootElement(), onAfkZoneDamage )

How would setting a element data value make you immortal?

It will cause a network trouble and you won't die e.e , hahhahaahhah

WARRING: BETTER Don't TEST this CODE in your PUBLIC Servers.

[Mr_Moose]

That loop you got there will proceed forever as 1+1 will always be 2

If you intend to use element data for what can be assumed as a safe zone (colshape), you should set it's value to true respective false once a player enter or exit that area and then check it client side.

local safeArea = createColRectangle ( 0, 0, 15, 15 ) 
function safeEnter ( plr, matchingDimension ) 
    if getElementType ( plr ) == "player" then 
        setElementData(plr, "AfkZone", true)    
    end 
end 
addEventHandler ( "onColShapeHit", safeArea, safeEnter ) 
function safeExit ( plr, matchingDimension ) 
    if getElementType ( plr ) == "player" then 
        setElementData(plr, "AfkZone", nil) 
    end 
end 
addEventHandler ( "onColShapeLeave", safeArea, safeExit )
