Implementations§

Source §

impl JoystickDirection

Source

pub fn from_degrees(degrees: f64) -> Self

calculate a JoystickDirection from degrees

0 degrees are on the positive X-Axis and then it rotates clockwise

§Examples

use macroquad_virtual_joystick::JoystickDirection;

let degrees = 153.5;
let direction = JoystickDirection::from_degrees(degrees);

assert_eq!(direction, JoystickDirection::DownLeft);

Source

pub fn to_local(&self) -> Vec2

convert the direction to a Vec2 with x and y

x and y are both one of these: [-1.0, 0.0, 1.0]

§Examples

use macroquad::prelude::Vec2;
use macroquad_virtual_joystick::JoystickDirection;

let direction = JoystickDirection::Up;
assert_eq!(direction.to_local(), Vec2::new(0.0, -1.0))
