How can I implement adjustable mouse sensitivity settings in my FPS game using Godot?

Implementing Adjustable Mouse Sensitivity in Godot

Understanding Mouse Sensitivity

Mouse sensitivity is a crucial setting in FPS games that influences a player’s control over their aim. Implementing adjustable sensitivity allows players to customize their experience to suit their preferences and hardware.

Creating the Sensitivity Setting

1. Instance a Settings Manager Node:

   var sensitivity = 1.0

2. Create a Slider UI Element: Design a UI with a slider to adjust sensitivity. This can be done using the Slider node in Godot, which provides a range typically between 0.1 to 5.
3. Connect the Slider to Update Sensitivity: Use the signal to update the sensitivity value in real-time.

slider.connect("value_changed", self, "_on_sensitivity_changed")

func _on_sensitivity_changed(value):
    sensitivity = value

Apply Sensitivity in Game Logic

To apply the sensitivity, modify how the player’s view reacts to mouse input. For instance:

var mouse_input = Input.get_mouse_motion() * sensitivity

Integrating Raw Input and Reducing Lag

• Enable Raw Input: Use Godot’s Input.set_use_raw_mouse_input(true) to get precise data from the mouse.
• Disable Mouse Acceleration: Use the system or game settings to disable any form of acceleration, ensuring a direct correlation between mouse movement and cursor movement.

Testing and Calibration

Encourage players to test and calibrate their settings in a practice mode or settings area to find the optimal sensitivity for their style.

Real-World Example

For instance, in many pro FPS games, such calibrations involve trials in different gaming environments to ensure that turning speed and precision can complement the player’s reflexes without being too fast or erratic.
