How to loop all players? - my code is not working

[_XxFedexX_]

Code:

function OnTick(TickTime)
    local ForEachPlayerTick = function(Player)
        Player:SendMessage("Player never recieves this message")
    end
end

Of course I have added hook

Code:

cPluginManager:AddHook(cPluginManager.HOOK_TICK, OnTick);

but it is not working.
Console is not giving any error.
Thank you very much!
