The worker case, the first argument is the data and the jaascript is the list of items that should be transferred. In Chrome, there’s a nice page to view all of the created blob URLs: For example, it can be a JSON object:.
If you’ve gone through the Getting Started Guide you will have downloaded Phaser javscript got everything set-up and ready to code. When postMessage is called from the main page, our worker handles that message by defining alaook onmessage handler for the message event. When using these techniques to inline your worker code, importScripts will only work if you supply an absolute URI.
The width and height properties set the size of the canvas element that Phaser will create. For example, in the next example the ‘msg’ property of the JSON message is accessible in both locations. Here are a few more ideas to get your brain churning:. The first argument doesn’t have to be an ArrayBuffer by the way.

One reason for this is that messages passed between main pages and workers are copied, not shared. One way to utilize importScripts in an inline worker is to “inject” the current url of your main script is running from by passing it to the inline worker and constructing the absolute URL manually.
The Basics of Web Workers – HTML5 Rocks
This is your list of transferrable items. For an sample of alqpok to spawn a subworker, see the example in the specification. Due to Google Chrome’s security restrictions, workers will not run locally e. The scene property of the configuration object will be covered in more detail further on in this tutorial. Hence, the failure will be due to cross origin restrictions. If the specified file exists, the browser will spawn a new worker thread, which is downloaded asynchronously.
Below is a example of using a string to pass ‘Hello World’ to a worker in doWork. This is the rendering context that you want to use for your game.
Here we will learn how to create a small game involving a player running and jumping around platforms, collecting stars and avoiding baddies. In Phaser 3 this is no longer the case and it’s no longer useful to store the game instance in a global variable. The recommended value is Phaser.
This article will only cover dedicated workers and I’ll refer to them as ‘web workers’ or ‘workers’ throughout. An instance of a Phaser.
