Implementing Haptic Feedback in Godot
To effectively use haptic feedback in your mobile game, Godot provides access to the device’s vibration capability through the OS.vibrate() method. This feature can greatly enhance user engagement by adding tactile feedback during gameplay events. Below is a detailed guide on implementing haptics in a mobile game using Godot.
Basic Vibration Integration
if Input.is_action_just_pressed("your_action"):
OS.vibrate(milliseconds)Here, replace 'your_action' with the appropriate input action, and milliseconds with the duration of the vibration.

Customizable Haptic Patterns
Godot doesn’t directly support vibration patterns natively, but you can emulate them by sequentially triggering vibrations using a coroutine or a timer. Here’s an example for a pattern:
func vibrate_pattern():
var pattern = [100, 200, 100, 300] # Duration in milliseconds for vibration and rest
for duration in pattern:
OS.vibrate(duration)
yield(get_tree().create_timer(duration / 1000.0), "timeout")Benefits of Haptic Feedback
- Tactile User Engagement: Enhances player immersion by providing sensory feedback during interactions.
- Adaptive Haptic Features: Tailors the intensity and pattern to the gameplay context, improving overall user experience.
- Interactive Feedback Design: Offers a new dimension of interaction, aside from visual and auditory feedback.
Best Practices
- User Preferences: Always allow users to enable or disable haptic feedback in the game settings menu.
- Performance Considerations: Test haptic feedback implementation across different devices to ensure consistent performance.
- Compliance: Follow platform guidelines and best practices for vibration use to avoid user discomfort.
