Controlling Gravity with Device Tilt

# Controlling Gravity with Device Tilt

Master the motion controls to create dynamic physics interactions by controlling gravity direction with device tilts.

## How Gravity Control Works

### Basic Mechanics
- **Tilt Direction**: Lizards fall toward the direction you tilt your device
- **Real-time Response**: Gravity changes immediately as you move your device
- **Natural Physics**: Earth-like acceleration with smooth transitions
- **All Orientations**: Works in portrait, landscape, and upside-down modes

### Device Sensors
Lizard uses your device's built-in sensors:
- **Accelerometer**: Detects device orientation and tilt angle
- **Gyroscope**: Provides smooth, responsive motion tracking
- **Core Motion**: Apple's framework for precise motion detection

## Gravity Control Techniques

### Basic Tilting
1. **Hold Device Steadily**: Use both hands for better control
2. **Tilt Gradually**: Make smooth, deliberate movements
3. **Watch Lizards**: Observe how they respond to your tilts
4. **Practice**: Experiment with different angles and speeds

### Advanced Techniques

#### Circular Motion
- **Rotate Device**: Move in circular motions
- **Creates Swirls**: Lizards follow circular gravity patterns
- **Visual Effects**: Beautiful flowing physics interactions

#### Quick Direction Changes
- **Sharp Tilts**: Sudden direction changes for dramatic effects
- **Bouncing**: Make lizards bounce between screen edges
- **Energy Transfer**: Watch physics momentum in action

#### Gentle Guidance
- **Subtle Tilts**: Small movements for precise control
- **Herding**: Guide lizards to specific screen areas
- **Artistic Patterns**: Create beautiful movement compositions

## Optimal Control Methods

### Device Handling
- **Two-Handed Grip**: Better stability and control
- **Secure Hold**: Prevent accidental drops during enthusiastic play
- **Comfortable Position**: Sit or stand in a comfortable position

### Motion Techniques
- **Smooth Movements**: Avoid jerky or sudden movements
- **Controlled Tilts**: Be intentional with your gravity changes
- **Reset Position**: Return to neutral position between movements

### Calibration Tips
- **Start Level**: Begin with device held level
- **5-Second Rule**: Hold steady for 5 seconds before tilting
- **Restart if Needed**: Close/reopen app if motion feels off

## Gravity Effects on Gameplay

### Physics Interactions
- **Collision Detection**: Lizards bounce naturally off screen edges
- **Momentum Conservation**: Physics follows real-world principles
- **Mass Behavior**: Each lizard responds according to its mass

### Creative Possibilities
- **Gravity Wells**: Create areas where lizards collect
- **Flow Patterns**: Guide lizards along paths
- **Physics Art**: Use gravity to create visual patterns
- **Timing Games**: Coordinate spawning with gravity changes

## Troubleshooting Motion Controls

### Common Issues

#### Gravity Not Responding
1. **Check Permissions**: Motion & Orientation must be enabled
2. **Restart App**: Close and reopen Lizard
3. **Device Restart**: Reboot iPhone/iPad if needed
4. **Calibration**: Hold device level for 5 seconds

#### Overly Sensitive Motion
1. **Steady Handling**: Use both hands
2. **Smooth Movements**: Avoid jerky motions
3. **Check Interference**: Remove magnetic cases or accessories
4. **Reset Calibration**: Restart app and hold level

#### Erratic Behavior
1. **Environmental Factors**: Move away from magnetic interference
2. **Device Issues**: Ensure no hardware problems with sensors
3. **Software Reset**: Close app completely and restart
4. **iOS Settings**: Check motion settings in device preferences

### When Motion Controls Don't Work
- **Alternative Play**: Gravity defaults to downward direction
- **Still Fun**: Full gameplay available without motion controls
- **Re-enable Later**: Can turn motion controls back on anytime

## Privacy and Safety

### Data Usage
- **Local Only**: All motion data processed on your device
- **No Transmission**: Motion information never leaves your device
- **No Storage**: Motion data not saved or collected

### Safe Usage
- **Secure Grip**: Always hold device securely
- **Clear Space**: Ensure adequate room for movement
- **Comfortable Position**: Don't strain while playing
- **Take Breaks**: Rest if you feel any discomfort
