Player lose health

[Tails]

Hi, I'm trying to create a script that lets the players health gradually drop by -1, kind of as if they were starving.

I have no idea how to learn this because the wiki doesn't explain me this.

function Starve(thePlayer) 
  
    setTimer(function()  
    SetElementHealth( thePlayer, getElementHealth(thePlayer) - 2 ), 1000, 0) 
  
    end 
end 
addEventHandler("onResourceStart", Starve)

1: You got missing argument 2 at addEventHandler.

2: "onResourceStart" has no player argument.

3: Lua is case-sensetive, so is not SetElementHealth, but setElementHealth.

Do I need to put type="client" in the meta file, server or none?

function Starve(thePlayer) 
    setTimer( 
    function()  
    setElementHealth( thePlayer, getElementHealth(thePlayer) - 2 ) 
    , 1000, 0) 
    end 
end 
addEventHandler("onPlayerSpawn", getRootElement(), Starve) 

Right now it's saying unexpected symbol near "," when debugging.

Can you also explain me a little bit as to why I need to put a 2nd argument in the eventHandler while on other scripts I don't? And what exactly means rootElement and what is the different between root and getRootElement?

Thanks in advance! It is much appreciated!

function Starve ( ) 
    setTimer ( 
        function ( thePlayer ) 
            if ( thePlayer and isElement ( thePlayer ) ) then 
                setElementHealth ( thePlayer, getElementHealth ( thePlayer ) - 2 ) 
            end 
        end 
        ,1000, 0, source 
    ) 
end 
addEventHandler ( "onPlayerSpawn", getRootElement(), Starve ) 

Is a server side script.

Thank you very much.

Why does it say source in

,1000, 0, source 

?

To pass the 'thePlayer' argument to the function executed by the timer.

To pass the 'thePlayer' argument to the function executed by the timer.

but if the timer has it's own function:

setTimer(function()end,ms,exec) 

then you don't really have to pass the argument through.

example:

function Starve ( ) 
    setTimer(function() 
        if ( source and isElement ( source ) ) then 
            setElementHealth ( source, getElementHealth ( source ) - 2 ) 
        end 
    end,1000, 0) 
end 
addEventHandler ( "onPlayerSpawn", getRootElement(), Starve )

    end,1000, 0) 
end 
addEventHandler ( "onPlayerSpawn", getRootElement(), Starve ) 

You need, it's a separated function.

well, it works for me
