In Virtual One: MMA, the match simulation and playback pipeline integrates three key systems:

✅ ROAD (Realistic Outcome Activation Decider)

• An LLM-powered outcome generator
• Consumes agent traits and stat profiles as input
• Produces a plausible fight result (winner, method, narrative log)
• Outputs structured match objects (e.g., agent IDs, result metadata, canonical event tags)

✅ GOAP (Goal-Oriented Action Planner)

• Behavior decision engine for moment-to-moment in-match tactics
• Constructs a state machine based on goals (attack, defend, counter, rest)
• Uses agent stat values (e.g. stamina, power, adrenaline) to weigh action priorities
• Supports dynamic reactivity
• Emits a sequence of action requests to drive animation

✅ UE (Unreal Engine-based Renderer)

• Real-time rendering of the simulation
• Consumes GOAP-generated exchanges
• Maps actions to animation states (e.g., jab, kick, block)
• Integrates overlays for stats, commentary, match status
• Provides a broadcast-quality viewing experience, including crowd audio, camera transitions, and highlight replays
