Raster PMTiles and slider

[vitoborneo]

With Leaflet I usually use OSM like basemap and raster tiles like custom map. This is an example:

I'm trying to do the same with PMTils, but slider and opacity doesn't work.

Please provide information on how to reproduce the problem

[bdon]

you are calling setOpacity on the PMTiles object, not the leaflet layer.

pmtiles.leafletRasterLayer(PMTiles1).addTo(map);

let layer = pmtiles.leafletRasterLayer(PMTiles1);
layer.addTo(map)
layer.setOpacity(...)

I updated with your advice, but nothing changed.

[bdon]

did you update

slide: function (event, ui) {
                layer.setOpacity(ui.value);
            }

and

var overlayMaps = {
 "Mappa": layer 
};

to properly reference the layer variable?

It's no good

I'm not able to volunteer helping you debug this JavaScript code, as this doesn't have to do with PMTiles but the usage of Leaflet. Please make sure that your code properly references the layer variable (not the pmtiles object). If you discover that after fixing the JS code there is an issue directly related to PMTiles please add more information.
