How do you make the respawn faster?

To do this, you will need to disable automatic respawning. This is easily done by setting the property of the Players service CharacterAutoLoads to false.

After that you need to write a function that will handle character respawning for each player that enters the game. We can use the PlayerAdded event to get each player. To actually load the character, we can use the function of player LoadCharacter. Using the Died event of humanoid we can detect when the player needs to be respawned. This event should be connected each time the player spawns so we will have to use the CharacterAdded event. When the Died event fires, we will simply wait a specific amount of time and call the LoadCharacter function again.

local respawnDelay = 5
 
game.Players.CharacterAutoLoads = false
 
game.Players.PlayerAdded:connect(function(player)
	player.CharacterAdded:connect(function(character)
		local humanoid = character:FindFirstChild("Humanoid")
		if humanoid then
			humanoid.Died:connect(function()
				wait(respawnDelay)
				player:LoadCharacter()
			end)
		end
	end)
	player:LoadCharacter()
end)
