i’m trying to make the volume level of a media_player work the same as the brightness of a light, so circle touch to adjust volume.
i tried this but the circle does not react to touch.
if (domain === 'media_player' && state) {
// wait 0ms for shadow dom
setTimeout(() => {
// then get elements
let elt = this.shadowRoot,
circle_slider = elt.getElementById('circle_slider'),
circle_value = elt.getElementById('circle_value'),
circle_stroke = elt.getElementById('circle_stroke');
// approximate position of thumb relative to circle
circle_slider.style.top = `${(circle_slider.value - 50) / 1.66 - 1}%`;
// debug position
let debug = false;
if (debug) circle_slider.style.opacity = 0.3;
// pass each event to handler
['click', 'input', 'mousedown', 'mouseup', 'touchstart', 'touchend'].forEach((event) => {
circle_slider.addEventListener(event, handler, { passive: true })
});
function handler(event) {
// "this" refers to slider
if (event.target === this) {
// bypass button-card tap_action
event.stopPropagation();
// update circle_value
circle_value.innerHTML = `${this.value}${tspan}${unit}</tspan>`;
// update stroke
circle_stroke.style.strokeDashoffset = c - this.value / 100 * c;
circle_stroke.style.strokeWidth = 'var(--c-stroke-width-dragging)';
// set cursor while dragging
if (event.type === 'mousedown' || event.type === 'input') {
this.style.cursor = 'grabbing';
} else {
this.style.cursor = 'grab';
}
// reset stroke width if value doesn't change
if (input == this.value && (event.type === 'click' || event.type === 'touchend'))
circle_stroke.style.strokeWidth = 'var(--c-stroke-width)';
// on release
if (event.type === 'mouseup' || event.type === 'touchend') {
// display loader if brightness is 0
if (circle_slider.value == 0 && elt.getElementById('loader')) {
elt.getElementById('loader').style.display = 'initial';
elt.getElementById('circle').style.display = 'none';
}
// set volume
hass.callService('media_player', 'volume_set', {
entity_id: entity.entity_id,
volume_level: this.value
});
}
}
}
}, 0);
return circle(state, input, unit);
}
${domain === 'media_player' && `
<input id="circle_slider" type="range" min="0" max="1" value="${input}">
`}
`;
