Checkpoints

Part of the Roblox Game Scripting section of Coddy's Lua journey. Lesson 22 of 24.

When a player is defeated, Roblox waits 5 seconds (Players.RespawnTime) and gives them a new character on a SpawnLocation. If the place has several SpawnLocations, Roblox picks one at random, so a checkpoint can turn into a starting point by accident.

Every player has a RespawnLocation property. Set it to a SpawnLocation and that player always respawns there. Obbies use it twice: when a player joins, it points at the start; when they reach a checkpoint, it moves to the checkpoint.

local Players = game:GetService("Players")
local camp = workspace.Camp
camp.Touched:Connect(function(hit)
	local player = Players:GetPlayerFromCharacter(hit.Parent)
	if player then
		player.RespawnLocation = camp
	end
end)

RespawnLocation belongs to each player, so one player reaching the camp does not move anyone else.

Challenge

Medium

The gray pad is workspace.Start, and the glowing blue pad is a checkpoint (both are SpawnLocations). This script is inside the checkpoint.

When a player joins, set their RespawnLocation to workspace.Start.
When a player touches the checkpoint, set their RespawnLocation to the checkpoint and turn it green: Color3.fromRGB(0, 255, 0).

Press Play, step on the checkpoint, then walk into the lava at the far end: you should come back on the checkpoint. Then Check.

Try it yourself

local Players = game:GetService("Players")
local checkpoint = script.Parent

Players.PlayerAdded:Connect(function(player)
	-- Start every player at workspace.Start
end)

checkpoint.Touched:Connect(function(hit)
	local player = Players:GetPlayerFromCharacter(hit.Parent)
	if player then
		-- Respawn this player here from now on

		-- Turn the checkpoint green
	end
end)
