Do a Barrel Roll NH

A port of the Do a Barrel Roll mod for Minecraft 1.7.10, with integrated FlightAssistant and ElytraHUD modules.

This mod overhauls elytra flight controls, giving the player full 3-axis (pitch, yaw, roll) camera and movement control during elytra flight — just like a real aircraft. The built-in FlightAssistant module adds an aviation-style HUD with speed/altitude tapes, heading indicator, attitude display, GPWS, stall warnings, and autopilot. The ElytraHUD module provides a simpler gauge-style HUD alternative.

Features

Do a Barrel Roll (Core)

• Full 3-axis flight control — Mouse controls pitch, yaw, and roll simultaneously using Rodrigues rotation
• Camera roll — First-person camera tilts to match the player's roll angle
• Barrel roll — Dedicated keybinds to perform a full 360° barrel roll with easing animation
• Configurable sensitivity — Independent sensitivity multipliers for pitch, yaw, and roll axes
• Input smoothing — Exponential smoothing on all axes to reduce jittery camera movement
• Banking — Optional automatic roll based on yaw input, simulating coordinated turns
• Automatic righting — Optionally levels the roll angle when no roll input is given
• Axis inversion — Toggle inversion for each axis independently
• Roll recovery on landing — Smooth exponential damping returns the camera to level after flight ends
• Third-person support — Player model rotates correctly in third-person view during flight

FlightAssistant (Aviation HUD)

• Attitude display — Artificial horizon with pitch ladder, roll indicator
• Speed tape — Scrolling speed scale with numeric readout (blocks/sec)
• Altitude tape — Scrolling altitude scale with numeric readout
• Heading tape — Compass heading with cardinal directions
• Flight path vector — Shows actual flight direction vs nose direction
• Radar altitude — Height above ground via raycasting
• GPWS (Ground Proximity Warning System) — Sink rate and terrain proximity alerts
• Stall warning — Detects low forward speed during flight
• Void proximity alert — Warning when approaching the void
• Elytra durability monitor — Tracks elytra durability with configurable units (raw/percentage/time)
• Alert system — Prioritized WARNING/CAUTION/ADVISORY alerts with blinking indicators
• Flight protections — Automatic pitch limits during stall, void proximity, and terrain warnings
• Autopilot — AP, FD (Flight Directors), and A/THR (Auto-Thrust) modes with keybinds
• Flight plan — Waypoint navigation with course deviation indicator
• Coordinates display — Current X/Z position at bottom of HUD
• Velocity components — Ground speed and vertical speed readouts
• Automation modes display — Shows active AP/FD/A-THR status
• Fully configurable — Colors, frame size, individual display toggles, alert modes

ElytraHUD (Gauge HUD)

• Airspeed gauge — Analog gauge showing current speed
• Altitude gauge — Dual-pointer gauge for altitude
• Vertical speed gauge — Climb/descent rate indicator
• Firework rate gauge — Boost rate tracking
• Elytra durability bar — Visual durability indicator
• Compass — Rotating compass with heading degrees
• Configurable — Toggle each gauge, titles, and numeric values independently
