UrlTemplateImageryProvider error

I’m trying to make a tile map background map using Cesium’s UrlTemplateImageProvider.
I’m trying to do it with a map of a site other than open street map, but when I apply it, I’m experiencing a problem where tiles are invisible or tiles are mixed up when I reduce the enlargement ratio.

Is there any way to solve this problem?

The codes I want you to see are as follows :

window.cesiumViewer = new Cesium.Viewer(‘cesiumContainer’, {
useDefaultRenderLoop: false,
animation: false,
baseLayerPicker : false,
fullscreenButton: false,
geocoder: false,
homeButton: false,
infoBox: false,
sceneModePicker: false,
selectionIndicator: false,
timeline: false,
navigationHelpButton: false,
imageryProvider : new Cesium.UrlTemplateImageryProvider({url :‘http://map3.daumcdn.net/map_2d/2111ydg/L{z}/{y}/{x}.png’}),});

Please tell me how to solve this problem.

Looks like you’ve got {x} and {y} flipped. I’d double-check those variables, possibly {z} while you’re at it. For example, if you find the coords of your mouse cursor over the map, do they match the coords of where the map is supposed to be?



Thank you for your answer.
Current {x},{y},{z}I’ve turned everything upside down as much as possible, but as a result, everything is in a similar state as the above.
I tried entering the coordinate system used on the map site, but there was no change.
I don’t think it’s a coordinate problem.

thank you,
