I was looking into PlayerEntered when I realized that PlayerEntered seems to be undocumented.
Is PlayerEntered only for when the player joins the game?
Or is it deprecated, and you are supposed to use PlayerAdded?
PlayerEntered isn't an event for Players, or any other service to my knowledge. Instead, I believe that the wiki page is for people who get confused on Event names.
Searching for PlayerEntered brought be to a wiki redirect link,
Because PlayerEntered doesn't exist/work, use PlayerAdded.
game.Players.PlayerAdded:connect(function(plr) end)
Good Luck!
I believe PlayerEntered is for when you are scripting with parts and PlayerAdded is when he/she joins the game
