Challenge

Validate whether ML-Agents can drive a skillful, high-stakes kick loop while keeping multiplayer sessions deterministic and lightweight enough for instant access.

Approach

Built an ML-Agents decision layer with 1:1 decision-to-outcome mapping for clean credit assignment.
Implemented reward shaping tied to distance-to-goal deltas.
Designed host-authoritative multiplayer with deterministic seed-based generation.
Added a WebGL devserver to enable zero-install testing and rapid iteration.

Results

Training behavior became easier to tune through high-level action control.
Deterministic session flow reduced host/client uncertainty.
Web-first testing made iteration faster and easier to share.

Key metrics

Measured impact

Metric	Before	After
Decision layer	Manual tuning	ML-Agents policy
Session sync	Manual checks	Deterministic seed sync
Testing loop	Install required	WebGL instant access

Implementation notes

High-level policies trained faster and generalized to procedural variance.
Deterministic seeds simplified multiplayer sync and validation.
WebGL testing accelerated iteration without sacrificing confidence.
