How to use pixi.js-legacy and verify that it has been activated?

Hello, this is not a bug report, but just a question on how to use pixi.js-legacy.

I would like to activate it in my word game, because player numbers have dropped after the upgrade to pixi.js v5 and some users complain about the “WebGL unsupported in this browser” error.

In my HTML-file I have added the CDN-link to pixi.js-legacy:

<SCRIPT TYPE="text/javascript" SRC="//cdn.jsdelivr.net/npm/pixi.js@5.2.1/dist/pixi.min.js"></SCRIPT>
<SCRIPT TYPE="text/javascript" SRC="//cdn.jsdelivr.net/npm/pixi.js-legacy@5.2.1/dist/pixi-legacy.min.js"></SCRIPT>
<SCRIPT TYPE="text/javascript" SRC="//cdn.jsdelivr.net/npm/pixi-filters@latest/dist/pixi-filters.js"></SCRIPT>

In my Javascript file I have the following code (without any imports at the top):

jQuery(document).ready(function($) {
        var app = new PIXI.Application({
                width: BOARD_WIDTH,
                height: BOARD_HEIGHT + SmallTile.HEIGHT,
                view: document.getElementById('board'),
                antialias: true,
                backgroundColor: 0xFFFFFF
        });

Thank you

Correct. When dealing with these full pre-builds of pixijs on a cdn, use either the regular version OR the legacy version, but not both

@stla a bit late but hopefully this will help others landing here: you should only have one installed. pixi.js-legacy is a superset of pixi.js, including both WebGL and Canvas (in practice, installing the legacy one with npm automatically installs the other one, not sure what the minified versions do).
