LOW-G ASTRONAUT CONTROLLER

Physics-Driven Movement for Low-Gravity & Zero-G Gameplay

The Low-G Astronaut Controller is a fully physics-based character controller designed for Moon, Mars, space station, and zero-gravity environments. It combines floaty low-gravity ground movement, responsive jetpack flight, magnetic boots for walking on any surface, and an optional true zero-G mode for EVA-style gameplay.

Built for flexibility and feel, this controller supports both arcade-style fun and more realistic simulation, all driven by a configurable profile system.

Core Features

Low-Gravity Ground Movement

• Configurable gravity values (Moon, Mars, Earth, or custom)
• Floaty jumps with long hang time
• Multiple air jumps (jetpack bursts)
• Responsive air control
• Coyote time and jump buffering

Jetpack Flying

• Toggleable 6DoF jetpack flight
• Full directional control (horizontal + vertical)
• Boost mode for fast traversal
• Launch force when activating from ground
• Optional fuel/stamina system with UI support

Magnetic Boots

• Walk on walls, ceilings, spheres, and asteroids
• Automatic surface alignment and edge climbing
• Dynamic gravity reorientation
• Seamless transitions between surfaces
• Jump-off and detach mechanics

Optional Zero-G Mode

• Disable gravity for true space movement
• Inertia-based floating with momentum
• Thruster propulsion and surface push-off
• Stabilization assist for smoother control

Animator & Audio Ready

• Full Animator parameter integration (movement, states, triggers)
• Ground, jetpack, and magnetic footstep sounds
• Jetpack and thruster audio
• Magnetic boots attach/detach sounds
• Velocity-based pitch variation

Profile-Driven Configuration

All movement behavior is controlled via a reusable Profile:

• Gravity strength & direction
• Ground movement speeds & acceleration
• Jump forces, air jumps, and hover behavior
• Jetpack flight tuning
• Magnetic boots strength and detection
• Optional fuel system
