Ports retail's CMotionInterp::get_max_speed (0x00527cb0). Returns motion-table-derived max speed (m/s) for InterpretedState.ForwardCommand: - RunForward: RunAnimSpeed (4.0) × (InqRunRate ?? MyRunRate) - WalkForward: WalkAnimSpeed (3.12) - WalkBackward: WalkAnimSpeed × 0.65 (BackwardsFactor from adjust_motion @ 0x00528010) - otherwise: 0 Decomp note: Binary Ninja emits a spurious void return for x87 FPU-returning functions; the actual float return is confirmed by both callers (StickyManager::adjust_offset @ 0x00555430, InterpolationManager::AdjustOffset @ 0x00555d52) which multiply the result by 2.0 to produce a catch-up speed in m/s. The per-command switch is consistent with get_state_velocity (0x00527d50) which uses the same constants. Used by InterpolationManager.AdjustOffset in Task 5 as 2 × GetMaxSpeed(). Until Task 5 wires it, the method is unused — covered by 4 unit tests. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
