@strudel/motion

This package adds device motion sensing functionality to strudel Patterns.

Install

``sh
npm i @strudel/motion --save
`

Usage

| Motion | Long Names & Aliases | Description |
|----------------------------|-----------------------------------------------------------|------------------------------------------|
| Acceleration | accelerationX (accX), accelerationY (accY), accelerationZ (accZ) | X, Y, Z-axis acceleration values |
| Gravity | gravityX (gravX), gravityY (gravY), gravityZ (gravZ) | X, Y, Z-axis gravity values |
| Rotation | rotationAlpha (rotA, rotZ), rotationBeta (rotB, rotX), rotationGamma (rotG, rotY) | Rotation around alpha, beta, gamma axes and mapped to X, Y, Z |
| Orientation | orientationAlpha (oriA, oriZ), orientationBeta (oriB, oriX), orientationGamma (oriG, oriY) | Orientation alpha, beta, gamma values and mapped to X, Y, Z |
| Absolute Orientation | absoluteOrientationAlpha (absOriA, absOriZ), absoluteOrientationBeta (absOriB, absOriX), absoluteOrientationGamma (absOriG, absOriY) | Absolute orientation alpha, beta, gamma values and mapped to X, Y, Z |

Example

`js
enableMotion() //enable DeviceMotion

setcpm(200/4)

$_: accX.segment(16).gain().log()

$:n("0 1 3 1 5 4")
.scale("Bb:lydian")
.sometimesBy(0.5,sub(note(12)))
.lpf(gravityY.range(20,1000))
.lpq(gravityZ.range(1,30))
.lpenv(gravityX.range(2,2))
.gain(oriX.range(0.2,0.8))
.room(oriZ.range(0,0.5))
.attack(oriY.range(0,0.3))
.delay(rotG.range(0,1))
.decay(rotA.range(0,1))
.attack(rotB.range(0,0.1))
.sound("sawtooth")

Setup SSL for Local Development

DeviceMotionEvent only works with HTTPS, so you'll need to enable SSL for local development.
Try installing an SSL plugin for Vite.

`sh
cd website
pnpm install -D @vitejs/plugin-basic-ssl
`

add the basicSsl plugin to the defineConfig block in strudel/website/astro.config.mjs

`js
vite: {
plugins: [basicSsl()],
server: {
host: '0.0.0.0', // Ensures it binds to all network interfaces
// https: {
// key: '../../key.pem', //
// cert: '../../cert.pem',
// },
},
},
`

generate an SSL certificate to avoid security warnings.

openssl req -new -newkey rsa:2048 -days 365 -nodes -x509 -keyout key.pem -out cert.pem`
