async-keyboard-pointer

Query keyboard and pointer states. Use keyboard and pointer events asynchronously.

Installation

npm i @dandre3000/async-keyboard-pointer

Usage

import {
    asyncKeydown,
    asyncPointerdown,
    getKeyboardButtons,
    getKeyboardState,
    getPointerStateMap,
    getPointerStates
} from '@dandre3000/async-keyboard-pointer'

await Promise.race([
    asyncPointerdown(0),
    asyncKeydown('Enter')
])

let intervalId

const callback = () => {
    const keyboardButtons = getKeyboardButtons('KeyW', 'KeyA', 'KeyS', 'KeyD', 'KeyP', 'KeyQ')
    // or
    const keyboardState = getKeyboardState()

    const pointerState = getPointerStates(0)
    // or for multitouch
    const pointerStateMap = getPointerStateMap()

    if (keyboardButtons[0]) console.log('KeyW')
    if (keyboardButtons[1]) console.log('KeyA')
    if (keyboardButtons[2]) console.log('KeyS')
    if (keyboardButtons[3]) console.log('KeyD')
    if (keyboardButtons[4]) console.log(pointerState)
    if (keyboardButtons[5]) {
        console.log('KeyQ')

        Promise.race([
            asyncPointerdown(0),
            asyncKeydown('Enter')
        ]).then(() => intervalId = requestAnimationFrame(callback))

        return cancelAnimationFrame(intervalId)
    }

    intervalId = requestAnimationFrame(callback)
}

intervalId = requestAnimationFrame(callback)

Exports
