onPlayerHealthChange event? (detect health change)

[johny46]

Hi. I've made a resource, which adds a Health column to the scoreboard. It gets updated on onPlayerSpawn and onPlayerDamage events. It works quite well, but it doesn't react to slapping, simply Slap doesn't call the onPlayerDamage event. Is there any other way to check whether player's health has changed? Of course other than getting the player's health every second and comparing it for changes If not, maybe you could consider adding such event to MTA?

There isn't an event, but you could trigger one each time you change health ( e.g: on slap ).

onClientRender 
getElementHealth 
setElementData 

Isnt it better to use this functions?

Wouldn't it spam my server a lot? I guess onClientRender is triggered very often.

Solidsnake, I didn't know that we are able to create our own events, thanks! I'll have to look further into it tomorrow.

PS. Cześć

You must use:

triggerEvent

and use getTickcount() to reduce data overclow.

getTickCount()

Using Table

Try this (but debug first i made it in 2 Minutes without checking for bugs or else)

  
-- Pleas add [TiLex Produkt] as commentary to your script while using this  
  
addEvent("onPlayerHealthChange", true) 
local playerOldHealthTable = {} 
  
function healthChangedTriggerFunction() 
    setTimer(function() 
        local playerTable = getElementsByType("player") 
        for index, player in ipairs(playerTable) do 
        local oldLive = playerOldHealthTable[player] 
            if oldLive and (oldLive > 0) then 
                local curLive = getElementHealth(player) 
                if not (curLive == oldLive) then 
                 
                local changedlive = 0 
                if (curLive > oldLive) then 
                    changedlive = (curLive - oldLive) 
                else 
                    changedlive = (oldLive - curLive) 
                end 
                    triggerEvent ( "onPlayerHealthChange", player, player, curLive, oldLive, changedlive) -- trigger Event 
                    playerOldHealthTable[player] = curLive 
                end 
            else 
                playerOldHealthTable[player] = (getElementHealth(player)) 
            end 
        end 
    end, 500, 0) 
end 
addEventHandler("onResourceStart", getResourceRootElement(getThisResource()), healthChangedTriggerFunction) 
  
  
  
-- EXAMPEL FUNKTION FOR EVENT 
function healthChanged(player, newHealth, oldHealth, changedLive) 
    -- Live changed. Here some stuff 
outputChatBox("Your Live had changed from " ..tostring(oldHealth).. " to " ..tostring(newHealth)), player, 255, 0, 0) 
end 
addEventHandler("onPlayerHealthChange", getRootElement(), healthChanged) 
  

EventName: onPlayerHealthChange

Parameters: element Player, int newhealth, int oldHealth, int howManyHealthChanged

Thanks for help. I appreciate your solutions, especially Schlammy's one, but it's too much overcomplicated for my simple needs. I followed the Solidsnake14's idea and I just do

setElementData(player,"Health",getElementHealth(player)) 

every time I slap a player. Works without any problem as of now Again thanks for your replies

[Castillo]

You're welcome.

onClientRender in combination with setElementData is never good.
