How do you make your character fade black, then disappear before respawn?

FIrst you remove their shirts and pants, then set all their body parts colors to black, and then decrease transparency to the approximate time before they respawn. You'll need the Humanoid.Died event for this.

This is some code I just worked out, may need modification if you use this script.

game.Players.PlayerAdded:connect(function(player)
player.CharacterAdded:connect(function(character)
character:WaitForChild("Humanoid").Died:connect(function()
-- Put the stuff like remove shirts, ect here
print (player.Name .. " has died...")
end)
end)
end)

This will at least give you a start. What this does is anything between the function() and end in the middle gets called when they die. This script sets the died event up when the player enters the game.
