Obby Checkpoint System
A classic obby checkpoint flow. Touching a checkpoint sets the player's spawn point — and stays set across deaths and re-joins. Each player has their own checkpoint independently.

The Prompt
“Build me an obby checkpoint system. Each checkpoint is a part. When a player touches one, they save it as their spawn. When they die, they respawn at their last checkpoint. Each player should have their own progression.”
Paste this — or any variation — into StudByStud and you’ll get the code below in seconds.
How it works
- Each checkpoint part is tagged 'Checkpoint' in Studio. Order matters only if you want to prevent skipping — the basic version awards any checkpoint a player touches.
- When the player touches a checkpoint, the server stores it in Player.RespawnLocation, which Roblox uses automatically when the character respawns.
- We also save the checkpoint number as a player attribute so other systems (UI, leaderboard) can read it cheaply.
- On CharacterAdded we re-apply the saved spawn so a freshly-respawned player still uses their last checkpoint, not the default lobby spawn.
- To prevent skipping, the version below also tracks the checkpoint number and refuses to assign a checkpoint that's lower than the player's current one.

Wires up every tagged checkpoint and binds it to per-player spawn state. Prevents skipping by tracking the highest checkpoint each player has reached.
What you’ll learn
Per-player checkpoint state via attributesPlayer.RespawnLocationCollectionService tags for designer-friendly setupCharacterAdded vs PlayerAdded for respawn handling
