woff

Robocode Tank Royale bot in C# (.NET 9).

Strategy

• Targeting — Multiple Choice Play It Forward (MCPiF): Monte Carlo simulation over 48 scenarios, predicting enemy movement with multi-order N-grams (order 2-7) across 1080 angle bins, plus virtual bullets to detect enemy fire from energy drops. Head-on fallback.
• Movement — Anti-Gravity: samples 36 arena points, weighted by repulsion from enemies, bullets, last enemy location, and corners. Stop-and-Go (sag): zig-zag ±90° near enemies (<250px) to break their targeting.

Run

Requires .NET SDK 9 and a Tank Royale server/runner:

dotnet build
dotnet run --no-build
