Players is not creatable, there's only one instance of it. It can only be accessed through its globally exposed variable.
Players is a table containing all Players who joined the game.
Players are indexed by their "player ID". Player IDs range from 0 to 15.
⚠️ Don't use ipairs for iterating over Players, but only pairs.
for id, player in pairs(Players) do -- id and player.ID have the same value here print(id, player.ID, player.Username) end
