Simulation for performance testing PIXI releases

PixiJS — The HTML5 Creation Engine

This project aims to provide a fast, lightweight 2D library that works across all devices. The PixiJS renderer allows everyone to enjoy the power of hardware acceleration without prior knowledge of WebGL. Also, it's fast. Really fast.

If you want to keep up to date with the latest PixiJS news then feel free to follow us on Twitter @PixiJS and we will keep you posted! You can also check back on our site as any breakthroughs will be posted up there too!

What to Use PixiJS for and When to Use It

PixiJS is a rendering library that will allow you to create rich, interactive graphics and cross-platform applications and games without having to dive into the WebGL API or deal with browser and device compatibility.

PixiJS supports WebGPU with fallback support for WebGL. As a library, PixiJS is a fantastic tool for authoring interactive content. Use it for your graphics-rich, interactive websites, applications, and HTML5 games. Out-of-the-box, cross-platform compatibility and graceful degradation mean you have less work to do and more fun doing it! If you want to create polished and refined experiences relatively quickly without delving into dense, low-level code, all while avoiding the headaches of browser inconsistencies, then sprinkle your next project with some PixiJS magic!

Boost your development and feel free to use your imagination!

Setup

It's easy to get started with PixiJS! Simply download a prebuilt build!

Alternatively, PixiJS can be installed with npm or simply using a content delivery network (CDN) URL to embed PixiJS directly on your HTML page.

NPM Install

npm install pixi.js

There is no default export. The correct way to import PixiJS is:

import * as PIXI from 'pixi.js';

CDN Install

Via jsDelivr:

<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/pixi.min.js"></script>

Or via unpkg:

<script src="https://unpkg.com/[email protected]/dist/pixi.min.js"></script>

Basic Usage Example

import { Application, Sprite, Assets } from 'pixi.js';

// The application will create a renderer using WebGL, if possible,
// with a fallback to a canvas render. It will also setup the ticker
// and the root stage PIXI.Container
const app = new Application();

// Wait for the Renderer to be available
await app.init();

// The application will create a canvas element for you that you
// can then insert into the DOM
document.body.appendChild(app.canvas);

// load the texture we need
const texture = await Assets.load('bunny.png');

// This creates a texture from a 'bunny.png' image
const bunny = new Sprite(texture);

// Setup the position of the bunny
bunny.x = app.renderer.width / 2;
bunny.y = app.renderer.height / 2;

// Rotate around the center
bunny.anchor.x = 0.5;
bunny.anchor.y = 0.5;

// Add the bunny to the scene we are building
app.stage.addChild(bunny);

// Listen for frame updates
app.ticker.add(() => {
    // each frame we spin the bunny around a bit
    bunny.rotation += 0.01;
});

How to build

Note that for most users you don't need to build this project. If all you want is to use PixiJS, then just download one of our prebuilt releases. The only time you should need to build PixiJS is if you are developing it.

If you don't already have Node.js and NPM, go install them. Then, in the folder where you have cloned the repository, install the build dependencies using npm:

npm install

Then, to build the source, run:

npm run build

How to generate the documentation

The docs can be generated using npm:

npm run docs

bunny-mark's Issues

https://pixijs.github.io/bunny-mark/ , "Click to add more"

After the bunnymark is started at https://pixijs.github.io/bunny-mark/ ,
people might not know that they can click to add more bunnies,
so it would be great if there'd be some text eg "Click to add more".

So what is his name?

Support Single Texture

See pixijs/pixijs#3738

This will provide a better comparison with v3 and v4.

Only bitmask transparency when "transparent" option enabled.

When selecting the "transparent" option, I would expect bunnymark to use alpha transparency for blending over the background. Instead seems to use bitmask transparency and looks like this:

Unlike the animated bunnys, the bunnys at the bottom have full alpha transparency.

Would it be possible to add an option for switching between alpha and bitmask transparency. I know almost nothing about WebGL, yet, but my project would required full alpha transparency for sprites, so this issue report doubles as a question if alpha transparency with sprites is possible at all.

Test doesn't start with new versions of Pixi.js

Attempting to run the test with all the default settings against the dev branch results in the test breaking with this error:

Uncaught TypeError: Right-hand side of 'instanceof' is not an object
    at BunnyMark.ready (index.js:228)
    at VersionChooser.stop (index.js:670)
    at VersionChooser.update (index.js:655)

It is checking if the renderer is an instance of PIXI.CanvasRenderer and my guess is that that is not bundled with what it is pulling due to the split between pixi.js and pixi.js-legacy.

Bunnymark caps at 200002 bunnies?

There was a link to http://www.goodboydigital.com/pixijs/bunnymark/ posted to /r/gamedev, and many users report bunnymark caps out at 200002 bunnies.

This seems such an arbitrary number, is this expected?

I tested on a i7 + GTX1080 in Firefox 50 on Windows 10.

powerPreference shouldn't be boolean

I was trying bunny-mark in Safari (Version 11.0.3 (13604.5.6)) on High Sierra 10.13.3 Beta.

I noticed a Type error. Turns out it's because the powerPreference is filled with a boolean value because of the checkbox in the input form. I think it should be a string 'default', 'high-performance' or 'low-power' based on the spec (https://www.khronos.org/registry/webgl/specs/latest/1.0/#5.2.1).

Not sure how to change the HTML form to make it more sensible, couldn't easily figure out where and how the form is parsed and passed to the initialization of the Pixi canvas.
