Is there a spawned event?

Is there a spawned event, that can trigger a function before a player spawns, so you can do a for loop, and you can make the player holographically come from transparency at 1, to 0, gradiently?

Well, there is a way to make a function that trigger when the character is spawned. First you need to check for the player,you could use the PlayerAdded event:

game.Players.PlayerAdded:connect(function (plr)

end)

Now with a player variable, you can use the CharacterAdded event:

game.Players.PlayerAdded:connect(function (plr)
	plr.CharacterAdded:connect(char)
		--Put content here
	end
end)

Well, now put the rest of your script there. Some links: PlayerAdded CharacterAdded

Note: probobly im wrong there.
