How do I write a script to respawn a player when they touch a part?

How do I write a script to respawn a player when they touch a part?

Simple!

function onTouch(part)
	if game.Players.GetPlayerFromCharacter(part.Parent) then --If a player touches then
		Player = game.Players:GetPlayerFromCharacter(part.Parent)	
		Player:LoadCharacter() --Respawn the player!
	end
end
script.Parent.Touched:connect(onTouch)

First off you would want it so that it would fire off an event when something touches it

script.Parent.Touched:connect(function(part)
	
end)

Now you would want to check if the part that touched it was part of a player

getPlayer = function(part)
	local player -- nil
	for _, v in pairs(game.Players:GetChildren()) do
		if part:IsDescendantOf(v.Character) then
			--This will loop through the players and if it was a part of any of the characters then it will go here
			player = v --The current value
		end
	end
	return player
end

script.Parent.Touched:connect(function(part)
	local player = getPlayer(part)

	if player ~= nil then
		
	end
end)

Next we will want to make it so the player will respawn and add a debounce so it doesn't glitch out!

local db = false

getPlayer = function(part)
	local player
	for _, v in pairs(game.Players:GetChildren()) do
		if part:IsDescendantOf(v.Character) then
			--This will loop through the player and if the part was a part of any of the characters then it will go here
			player = v --The current value
		end
	end
	return player
end

script.Parent.Touched:connect(function(part)
	if db == true then return end --Stop running if debounce is equal to true
	local player = getPlayer(part)

	if player ~= nil then
		db = true
		player:LoadCharacter() --Respawns the character

		wait(0.5) --So it doesn't run the event multiple times
		db = false
	end
end)
