How it works, step by step
- 1
Tool equips a viewmodel; client handles ADS, recoil pattern and muzzle VFX locally.
- 2
Fire input raycasts locally for tracer visuals, but sends FireRequested{origin, direction} only.
- 3
Server re-raycasts from a validated origin near the character, applies spread, finds the hit.
- 4
Damage, headshot multipliers and ammo accounting happen server-side in one atomic step.
- 5
Reload requests validate reserve ammo and timing windows.
Concepts you'll use
- Server re-raycast
- Recoil patterns
- Atomic ammo accounting
Mistakes that cost you players
- Client-computed damage = aimbot + one-shot exploits.
- Infinite ammo bugs from decrementing on the client and trusting echoes.
