What is this for?

So this is a mess for me. What's for example the difference between player, source, ?? And when do I put things like this:

function ( source ) 
--... 
end

There's no "difference", since you can use your own names instead of "player" you can put "monkey" and it would still work as long as you use "monkey". 'source' is defined by MTA, used for events.

but in some functions i use see:

this doesnt work

function test ( ) 

this works

function test ( source )

Define source as argument isn't very smart. Source only gets created by events as solidsnake said.

A addCommandHandler don't have any source if you using it.

server side

addCommandHanlder("test", 
function (player) 
  
end) 
  
-- VS -- 
  
addEventHandler("onPlayerWasted",root, 
function() 
local player = source 
end)
