Question about const's

[Damian Pastorini]

Hi everyone, 

My name is Damian, I'm new in Phaser.

I was working with a code sample that has the following:

    <script>
        const WEBGL_RENDERER = true;
        const CANVAS_RENDERER = true;
    </script>
    <script type="text/javascript" src="./client.js"></script>

I'm really not sure for what are the const's, I'm working in a "2d-titled" game and nothing changes if I comment both.

Any recommendations or clue about if I should keep them and why?

Thanks!

WebGL just increases performance of your game.

Canvas rendering is the slower option.

 

I have never seen setting this constants manually. I always set them in the "config" variable.

 

var config = {
    type: Phaser.AUTO,
    width: 800,
    height: 600,
    scene: {
        preload: preload,
        create: create,
        update: update
    }
};

var game = new Phaser.Game(config);

The type "Phaser.AUTO" automatically tries to use WebGL, but if the browser doesn't support it it'll fall back to Canvas rendering.

 

If you set the correct type in the config variable i think you can delete the two lines, but maybe a phaser expert knows more than I.

You only need them if you rebuild Phaser itself. You could shrink the filesize by using only 1 (or even no) renderer.

Well... I'm using Parcel but I think it's for rebuild Phaser itself but to rebuild the code I use that implements Phaser.

I'll share with you the game-base once it's relative working (is a Colyseus + MySQL + Phaser 3 implementation for a MMORPG), hopefully I will get some feedback as good as yours 

Thanks both!
