Make models clickable

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

JavaScript

async function init() {
    // Import the needed libraries.
    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',
        gestureHandling: 'COOPERATIVE',
    });

    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: 0.15,
        altitudeMode: 'CLAMP_TO_GROUND',
    });

    model.addEventListener('gmp-click', function () {
        this.scale = Math.random() * (0.5 - 0.1) + 0.1;
    });

    document.body.append(map);
    map.append(model);
}

void init();

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;
}

HTML

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

        <link rel="stylesheet" type="text/css" href="./style.css" />
        <script type="module" src="./index.js"></script>
        <script>
            // prettier-ignore
            (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"
            });
        </script>
    </head>
    <body>
        <div id="map"></div>
    </body>
</html>
