Struct MouseScrollAxis

pub struct MouseScrollAxis {
    pub axis: DualAxisType,
    /* private fields */
}

Amount of mouse wheel scrolling on a single axis (X or Y).

Value Processing

You can customize how the values are processed using a pipeline of processors. See WithAxisProcessingPipelineExt for details.

use bevy::prelude::*;
use bevy::input::InputPlugin;
use leafwing_input_manager::plugin::{AccumulatorPlugin, CentralInputStorePlugin};
use leafwing_input_manager::prelude::*;
use leafwing_input_manager::user_input::testing_utils::FetchUserInput;

let mut app = App::new();
app.add_plugins((InputPlugin, AccumulatorPlugin, CentralInputStorePlugin));

// Y-axis movement
let input = MouseScrollAxis::Y;

// Scrolling on the chosen axis activates the input
MouseScrollAxis::Y.set_value(app.world_mut(), 1.0);
app.update();
assert_eq!(app.read_axis_value(input), 1.0);

// You can configure a processing pipeline (e.g., doubling the value)
let doubled = MouseScrollAxis::Y.sensitivity(2.0);
assert_eq!(app.read_axis_value(doubled), 2.0);

Fields

axis: DualAxisType

The axis that this input tracks.
