How it works

Each fighter is modeled with two live scalars — stamina S (energy reserve, 0–100) and balance B (stability margin, 0–100). Strikes drain the target's stamina and balance in proportion to your power slider; both regenerate slowly while standing.

A takedown attempt is a leverage problem: driving through an opponent's center of mass (CoM) past the edge of their base of support (BoS — the stance width between the feet) topples them. The success probability is a logistic function of the net torque advantage:

Attack torque   τ_a = Power × (1 + (100−S_defender)/200)
Defense torque  τ_d = B_defender × 0.9
Advantage       Δτ  = τ_a − τ_d
P(takedown) = clamp(0.5 + Δτ / 140, 0.05, 0.92)

A tired defender (low S) generates less resisting torque even at full balance — fatigue erodes technique, not just power. A successful takedown drops the defender's balance to 0 and moves the fight to the ground with you in top position (guard).

On the ground, position follows a five-stage dominance ladder: Guard → Half Guard → Side Control → Mount → Back Control. Each "Advance" roll compares your stamina-scaled grappling pressure against the bottom fighter's stamina-scaled retention:

P(advance) = clamp(0.5 + (S_top − S_bottom) / 130, 0.1, 0.85)

Reaching Back Control ends the round in your favor (a control-based stoppage); if your own stamina falls below the bottom fighter's, they can reverse and put you on bottom instead. This mirrors why cardio — not just raw power — decides real MMA ground exchanges.
