for i,v in pairs (getElementsByType("player")) do

function callServerFunction(funcname, ...) 
    local arg = { ... } 
    if (arg[1]) then 
        for key, value in next, arg do arg[key] = tonumber(value) or value end 
    end 
    loadstring("return "..funcname)()(unpack(arg)) 
end 
addEvent("onClientCallsServerFunction", true) 
addEventHandler("onClientCallsServerFunction", resourceRoot , callServerFunction)

uhm read in the wiki for what is it.

key(valvue) is for function, tables ?

is it constanse

[MexUK]

ipairs() is for tables where the keys are type 'number', start at 1 and increase by 1 on the next element

the elements don't have to be added to the table in key order

local Table = { 'a', 'b', 'c' } 
  
local Table = { [1]='a', [2]='b', [3]='c' } 
  
local Table = {} 
Table[1] = 'a' 
Table[2] = 'b' 
Table[3] = 'c' 
  
local String = table.concat(Table, " ") 
  
local Table = { unpack(Table) } 
  
for i,v in ipairs(Table) do 
end 

pairs() is for when the above doesn't apply, the keys can be any type lua supports, it will loop around all the elements in the table, but they are in a random order

local Table = { 'key'='a', 'key2'='b', 'key3'='c' } 
  
local Table = {} 
Table['key'] = 'a' 
Table['key2'] = 'b' 
Table['key3'] = 'c' 
  
local Table = {} 
Table[2] = 'a' 
Table[8] = 'b' 
Table[0] = 'c' 
  
for k,v in pairs(Table) do 
end
