# phaser-web-workers
A simple Phaser plugin that allows you to easily integrate Web Workers in your game, this is ideal for offloading cpu intensive work (pathfinding, maybe physics?) to a seperate browser thread.

Currently still in alpha-phase and not yet feature complete.

Getting Started
---------------
First you want to get a fresh copy of the plugin. You can get it from this repo or from npm, ain't that handy.
```
npm install @azerion/phaser-web-workers --save-dev
```

Next up you'd want to add it to your list of js sources you load into your game
```html

<script src="node_modules/phaser-input/build/phaser-web-workers.js"></script>

<script src="//cdn.fbrq.io/phaser-web-workers/v0.1.0/phaser-web-workers.min.js"></script> 
```

After adding the script to the page you can activate it by enabling the plugin:
```javascript
game.add.plugin(PhaserWebWorkers.Plugin);
```

Usage
-----
As this is a simple wrapper (including preloading) of workers, not a lot of exciting stuff needs to happen in order to get this set up.

First step is to preload the worker whenever you do you usual preloading:
```javascript
        function preload() {
            //Preload the file we'd like to use as a worker
            game.load.worker('myWorker', 'worker.js');
        }
```

After that it's just a matter of creating the worker, assigning a listener and send it some data.
The worker is configured to handle the incomming data (or errors) and responed whenever it's done processing.
```javascript
//Create the worker from cache
var worker = game.make.worker('myWorker');
//Assign the message listener
worker.onMessage.add(function (e) {
    console.log('received worker data!', e);
});           
//Assign the error listener
worker.onError.add(function (e) {
    console.log('Oh no, something went wrong!', e);
});

```

Don't forget to destroy your worker when your done with it (they take a decent amount of memory):
```javascript
worker.destroy();
```

Why use a Webworker?
--------------------
Webworkers are ideal for doing heavy computations whilst not locking up your game. The browser accomplishes this by running everything a worker does in a seperate thread. So you can offload your fancy stuff like pathfinding.

Browser Support
