Building an Obby in Roblox

Add GateNumber attributes from 1 through 5 to the five gate triggers and read those attributes from a script.

Implement touch logic that advances only the touching player's checkpoint when the gate number is exactly one greater than their current checkpoint, ignoring skipped or repeated gates.

Add a start SpawnLocation and safe checkpoint SpawnLocations just beyond the five gates, associating each location with the correct checkpoint number.

Implement session-only respawn behavior that updates a player's RespawnLocation after each valid gate and makes the hazard floor return fallen players to their latest checkpoint.

Create numbered gate signs and simple color or arrow guidance using Parts, SurfaceGuis, and TextLabels in Studio's visual editor.

Add a start-area instruction that explains the gate order, what happens after falling, and where to read the current checkpoint number.

Implement a finish pad that moves only a player with checkpoint 5 to the victory area, preventing players who skipped gates from finishing.

Test the complete race with a checklist covering skipped gates, repeated gates, falls at different checkpoints, normal completion, and a new session.

Inspect a free Toolbox decoration in Explorer and either reject it if it contains unexplained scripts or use it only as nonessential visual decoration.

Publish the completed experience and play the published version to verify the start position, ordered checkpoints, fall respawning, progress display, and finish condition.
