Drone Control System
A downloadable asset pack for Windows, macOS, Linux, and Android
🚁 Drone Control System
Drone Control System is a polished Unity package designed for simulation, action, exploration, prototype, and vehicle-based projects that need responsive and believable drone flight without building the entire controller from scratch.
The system uses Rigidbody-based physics to provide stable aerial movement, throttle-controlled lift, surface-relative hover height, strict X/Z stabilization, realistic motor-off free-fall, camera orbit controls, propeller audio feedback, and a live HUD displaying important flight data.
Build responsive drone gameplay with physics-based lift, automatic stabilization, throttle-controlled altitude, realistic descent behavior, camera orbit controls, propeller audio, and live flight telemetry.
⚡ System Overview
Drone Control System provides a ready foundation for controlling a physics-driven drone inside Unity. The controller is built around a standard Rigidbody and focuses on creating predictable, stable, and responsive flight behavior that still feels physically grounded.
Vertical movement is controlled entirely through throttle. Instead of directly forcing the drone toward a fixed world-space altitude, the system can map throttle percentage to a target height relative to the surface below the drone.
This makes the controller useful for indoor environments, outdoor terrain, obstacle courses, exploration scenes, simulation projects, and gameplay where the drone needs to maintain a consistent distance above changing surfaces.
✨ Main Features
-
Physics-Based Drone Flight
Uses Unity Rigidbody physics for movement, lift, gravity, stabilization, and descent behavior. -
Throttle-Only Vertical Lift
Control ascent and hover height using a configurable throttle value rather than separate vertical movement controls. -
Surface-Relative Hover Height
Map throttle percentage to a target height above the surface detected below the drone. -
Stable X/Z Leveling
Automatically keeps the drone level on its horizontal axes while allowing smooth movement. -
Smooth Forward & Backward Flight
Maintain responsive directional movement without losing the stabilization behavior. -
Immediate Motor-Off Free-Fall
Turn the motors off and allow gravity to immediately take control of the drone. -
Realistic Descent Behavior
Motor-off descent remains gravity-driven instead of artificially maintaining altitude. -
Camera Orbit Controls
Adjustable yaw and pitch controls allow the player to look around the drone smoothly. -
Propeller Audio Feedback
Propeller sound can react dynamically to throttle level for clearer flight feedback. -
Live Flight HUD
Display throttle percentage, current height, and motor status directly on screen. -
Easy Rigidbody Integration
Designed to work with standard Rigidbody-based drone rigs and Unity components.
🎚 Throttle-Based Flight
The controller uses throttle as the primary vertical-flight input. Increasing throttle raises the desired hover height, while reducing throttle lowers it.
This creates a simple control model that is easy to understand while still supporting believable drone behavior.
Throttle System Includes
- Configurable throttle percentage
- Motor-powered ascent
- Throttle-based hover height
- Surface-relative altitude targeting
- Adjustable vertical response
- Live throttle HUD feedback
📏 Surface-Relative Hover Height
Instead of always measuring altitude from a fixed world-space position, the drone can determine its height relative to the surface directly underneath it.
This allows the drone to react more naturally when flying over terrain, platforms, buildings, ramps, or other changing surfaces.
Example Behavior
- Low throttle keeps the drone close to the surface.
- Medium throttle maintains a moderate hover distance.
- Higher throttle increases the target surface-relative height.
- Terrain elevation changes can be reflected in the drone's hover behavior.
🧭 Automatic Stabilization
The system includes strict X/Z leveling to help the drone remain visually stable while flying.
This prevents excessive unwanted tilting while still allowing smooth directional movement and makes the controller suitable for projects where predictable flight behavior is more important than advanced real-world flight simulation.
Stabilization Features
- Automatic horizontal leveling
- Stable Rigidbody orientation
- Smooth forward movement
- Smooth backward movement
- Reduced unwanted roll
- Reduced unwanted pitch instability
⚙️ Motor Control
Motor state directly affects the drone's ability to generate lift.
When the motors are active, the controller applies the forces required for throttle-based flight. When the motors are switched off, lift stops immediately and gravity becomes the dominant force.
Motor-Off Behavior
- Lift force stops immediately
- Gravity takes control
- The drone begins free-fall
- No artificial altitude hold remains active
- HUD motor status updates automatically
- Audio feedback can react to the motor state
🎥 Camera Orbit System
The included camera controls allow the player to orbit around the drone using configurable yaw and pitch input.
Camera sensitivity and rotation behavior can be adjusted to suit slower simulation projects or faster action-focused gameplay.
Camera Features
- Horizontal yaw rotation
- Vertical pitch rotation
- Adjustable camera sensitivity
- Smooth orbit behavior
- Useful for third-person drone control
- Easy to adapt to custom camera rigs
🔊 Propeller Audio Feedback
Propeller audio can respond dynamically to the current throttle value, giving the player immediate audible feedback about motor activity and flight intensity.
The system can be connected to your own propeller loops, electric motor sounds, turbine effects, or other custom audio.
Possible Audio Uses
- Idle propeller sound
- Increasing pitch with throttle
- Increasing volume with throttle
- Motor startup feedback
- Motor shutdown feedback
- High-throttle flight effects
📊 Live Flight HUD
The included HUD provides useful real-time information while flying.
Displayed Information
-
Throttle %
Displays the current throttle percentage. -
Current Height
Displays the drone's detected surface-relative height. -
Motor Status
Shows whether the motors are currently active or disabled.
The HUD uses TMP_Text components, making it easy to replace the included visuals with your own interface design.
🔧 Easy Unity Integration
The package is designed around standard Unity components and can be added to a Rigidbody-based drone setup with minimal configuration.
