How it works, step by step
- 1
Listen for Shift keydown on the client; tween WalkSpeed up for instant feel.
- 2
Track stamina locally for the bar UI, but send start/stop intent to the server.
- 3
Server validates sprint state (is the player actually moving?) and drains authoritative stamina.
- 4
When server stamina hits zero it fires back forcing the client to stop sprinting.
- 5
Cleanly reset WalkSpeed on character respawn.
Concepts you'll use
- Prediction + reconciliation
- ContextActionService bindings
- Stamina as server state
Mistakes that cost you players
- Setting WalkSpeed only on the server feels laggy; predict locally then reconcile.
- Forgetting CharacterAdded resets — sprint breaks after death.
