What's wrong

[GamerDeMTA]

@ 'setElementHealth' [Expected element at argument 1, got number]

And no one of the script works. It's server - side

function p ( source ) 
setPedStat( source, 24, 200 ) 
end 
  
function u ( source ) 
    setElementHealth ( source, 200 ) 
end 
    
addEventHandler("onPlayerLogin", root, p) 
addEventHandler("onPlayerSpawn", root, u)

function p () 
setPedStat( source, 24, 200 ) 
end 
  
function u () 
    setElementHealth ( source, 200 ) 
end 
    
addEventHandler("onPlayerLogin", root, p) 
addEventHandler("onPlayerSpawn", root, u)

source is never inside Funtion().

Inside the function are returned value's you can find on wiki.

For "onPlayerSpawn" you get :

float posX, float posY, float posZ, float spawnRotation, team theTeam, int theSkin, int theInterior, int theDimension

inside the function.
