Human-like AI & Race Control for Assetto Corsa
2 lightweight apps: ApexFlow Core + ApexFlow Events HUD
Thinking AI • Clean 2×2 starts • Live delta gaps • Persistent penalty points
Why ApexFlow? • Features • Installation • Configuration • Quick Start • API • Roadmap
AI that thinks instead of crashing. Every driver has a personality, picks its own line, brakes progressively into slow corners, and only attacks on straights with a real gap — no kamikaze dives, no train formation.
- 🪶 Lightweight: 9 modules • ~230 KB • 4 windows • zero errors in
custom_shaders_patch.log - 🔌 Offline-first: no online dependencies, per-track
ApexFlow_config.luaauto-save - 🏁 2 apps:
ApexFlowcore (1024×760+ setup) +ApexFlow EventsHUD overlay (360×260) - 🌧️ Rain-aware: grip logic desensitized in the wet, AI keeps its pace instead of crawling
- 🚩 No conflicts: flags and track limits are handled by AC itself — no double penalties
| System | What it does | Where |
|---|---|---|
| 🧠 Thinking AI | Chill / Normal / Attack mix (0–100, try 65–70) • 5-class multiclass support • attacks only on straights with a 6–150 m gap and closing speed • aborts dives before braking zones • own line per driver, yields side-by-side in corners |
Drivers tab |
| 🏁 Race & Starts | Aligned 2×2 rolling formation • adaptive fuel strategy with mandatory stops • real pit speed limit • endurance presets (Sprint → 24h) | Race tab |
| 📏 Live gaps | Gap to leader in meters • gap + time delta to the car behind (blue when lapped) • per-sector delta, wrap-safe | Events HUD |
| 📊 Penalty points | L1 = 1 PP … L6 = 6 PP, persisted across sessions via ac.storage |
Events HUD |
| ☁️ Extras | GitHub update checker • per-track learning memory • lap telemetry CSV | System tab |

Rain: nothing to configure — the AI automatically desensitizes grip sliding and keeps its rhythm instead of crawling.
Backmarkers: the car behind shows blue when lapped, with time delta.
Penalty points: PP 3 · L3 persists across qualifying and race — check Events.
