Make models clickable

The following example shows how to change a model's scale when clicked.

JavaScript

async function init() {
    const { Map3DElement, Model3DInteractiveElement } = await google.maps.importLibrary("maps3d");
    const map = new Map3DElement({
        center: { lat: 39.1178, lng: -106.4452, altitude: 4395.4952 }, range: 1500, tilt: 74, heading: 0,
        mode: "HYBRID",
    });
    const model = new Model3DInteractiveElement({
        src: 'https://maps-docs-team.web.app/assets/windmill.glb',
        position: { lat: 39.1178, lng: -106.4452, altitude: 4495.4952 },
        orientation: { heading: 0, tilt: 270, roll: 90 },
        scale: .15,
        altitudeMode: "CLAMP_TO_GROUND",
    });
    model.addEventListener('gmp-click', (event) => {
        const clickedModel = event.target;
        clickedModel.scale = Math.random() * (0.5 - 0.1) + 0.1;
    });
    document.body.append(map);
    map.append(model);
}
init();
index.js

CSS

/* * Always set the map height explicitly to define the size of the div element
 * that contains the map. 
 */
html,
map {
  height: 100%;
}
body {
  height: 100%;
  margin: 0;
  padding: 0;
}
style.css

HTML

<html>
  <head>
    <title>Map</title>

    <link rel="stylesheet" type="text/css" href="./style.css" />
    <script type="module" src="./index.js"></script>
  </head>
  <body>
    <div id="map"></div>

    <!-- prettier-ignore -->
    <script>(g=>{var h,a,k,p="The Google Maps JavaScript API",c="google",l="importLibrary",q="__ib__",m=document,b=window;b=b[c]||(b[c]={});var d=b.maps||(b.maps={}),r=new Set,e=new URLSearchParams,u=()=>h||(h=new Promise(async(f,n)=>{await (a=m.createElement("script"));e.set("libraries",[...r]+"");for(k in g)e.set(k.replace(/[A-Z]/g,t=>"_"+t[0].toLowerCase()),g[k]);e.set("callback",c+".maps."+q);a.src=`https://maps.${c}apis.com/maps/api/js?`+e;d[q]=f;a.onerror=()=>h=n(Error(p+" could not load."));a.nonce=m.querySelector("script[nonce]")?.nonce||"";m.head.append(a)}));d[l]?console.warn(p+" only loads once. Ignoring:",g):d[l]=(f,...n)=>r.add(f)&&u().then(()=>d[l](f,...n))})
        ({key: "AIzaSyA6myHzS10YXdcazAFalmXvDkrYCp5cLc8", v: "beta",});</script>
