Step-1:

From your dashboard go to Plugins → Add New Plugin and search “iframe“.

Install and activate the plugin marked in the image above.

Step-2:

Go to Pages and click on the page you want to embed the iframe in. Then click on Edit with Elementor.

Then add a container widget for your iframe element.

Step-3:

Add a shortcode widget to the previously created container.

Step-4:

Enter the following shortcode in the shortcode widget. Replace src attributes value with your own streaming URL.

Sample Shortcode:

[iframe allow="camera;microphone" id="iframe_1"   src="https://connector.eagle3dstreaming.com/v5/demo/E3DSFeaturesTemplate/E3DS-Iframe-Demo" width="100%" height="500px" allowfullscreen]

Step-5:

Now apply all the changes and the stream should start.

Communicate with Your App:

Step-1:

First you’ll need to add a plugin to use javascript in your website. Go to Plugins → Add New Plugin and search “simple custom css and js“.

Install and activate the marked plugin.

Step-2:

Go to Dashboard → Custom CSS $ JS → Add Custom JS. Now add the title of the javascript file. You can get the necessary javascript codes here: https://github.com/e3ds/E3DS-Iframe-Demo/tree/wordpress-demo-js

Add all three javascript files one by one and publish them. After publishing you can go to All Custom Code to view all your javascript files.

Step-3:

Now go back to your page and add another container. Inside that container add an HTML widget.

Edit HTML to add buttons with click handlers in your webpage.

Sample HTML:

 <div>
    <div>
    <button onclick="switchTo(1)">Teleport(1)</button>
    <button onclick="switchTo(3)">Teleport(3)</button>
    </div>
    <br/>
    <input type="text" placeholder="Enter Streaming URL" id="urlInput"/>
    <button onclick="updateStreamURL()">Set URL</button>
</div>

Here, switchTo() and updateStreamURL() functions are defined inside demo.js file.

function switchTo(val) {
	console.log("=== Registered switchTo action, Value is: ", val);

	let descriptor = {
		Teleport: val
	};
	//emitUIInteraction(descriptor);
	let obj ={
			cmd: "sendToUe4",
			value: descriptor,
	};
	document.getElementById("iframe_1").contentWindow.postMessage(JSON.stringify(obj), "*");
}

function updateStreamURL(){
	const url = document.getElementById('urlInput').value;
	document.getElementById("iframe_1").src = url;
}

Step-4:

Receiving data from Unreal App to the parent webpage

After sending the data we will receive a response the the unreal app. This response can be caught by using window.e3ds.onEvent function. Here’s an example of that -

window.e3ds.onEvent("increaseSessionExpireTime", (data) => {
	alert("Increasing session expire time: " + data.value);

});
