(First of all, I'm sorry for being a total noob to scripting, but I had a large hiccup in time and now I forgot almost everything.)
Okay, so I have this...
local Players = game:GetService("Players")
Players.PlayerAdded:connect(function(player)
end)
And, As stated, I have no idea how to find a player's entity (body parts, hats, Humanoid, etc.)
Is there a way to find a player just from this? thanks.
P.S. Is this suppost to be in a localscript?

That is not what I was asking, I was trying to find the entity, not what you can do with game.ServerScriptService, Sorry for any confusion.
if you mean character then i just edited the answer
