PixiJS vs Cocos2d: Making the Right Decision

For fast, graphics-heavy web applications, online games or interactive content, PixiJS outshines with its speed and ease in cross-platform compatibility. However, if you’re aiming for less code in game development and desire a full game engine with a complete toolkit, Cocos2d stands as a superior choice.

Key Differences Between PixiJS and Cocos2d

• Framework: PixiJS is a rendering system while Cocos2d is a full software framework for building games and applications.
• Speed & Compatibility: PixiJS focuses on speed and is perfect for cross-platform, graphics-heavy applications. Cocos2d, while also fast, provides a complete toolkit making it a superior choice for less code in game development.
• Features: PixiJS excels in features like automatic sprite & geometry batching. Cocos2d boasts features like procedural animation and high precision text.
• Nature: PixiJS is a ‘creation engine’, ideal for moving things on screen fast whereas Cocos2d is a game engine with comprehensive tools.

Cons of PixiJS

• More geared for 2D, limits in 3D visuals creation
• While user-friendly, there is a learning curve involved particularly in mastering the advanced features

What Is Cocos2d and Who’s It For?

Cocos2d is a robust, open-source software framework designed for building cross-platform games, applications, and other GUI programs. Recognizable games like FarmVille, Geometry Dash, and Plague Inc have been brought to life using Cocos2d. The framework is suitable for both new and experienced developers, who desire a complete toolchain for multiformat game development with a focus on 2D graphics and interactivity.

Pros of Cocos2d

• Free, open-source with a supportive community, allowing for easy problem-solving
• Multi-language support, including Python, Obj-C, and C++
• Offers a complete toolchain, including animation, UI, physics system, and audio features
• Lightweight but powerful, providing fast rendering speed

Cons of Cocos2d

• Requires advanced programming skills to fully harness its potential
• Focused on 2D graphics, lacks native 3D support

PixiJS vs Cocos2d: Pricing

Both technologies, PixiJS and Cocos2d, are free and open source providing affordability without compromising on performance.

PixiJS

PixiJS, a fast and feature-rich animation library, is open source and governed by an MIT licence. Built for 2D animations, this technology is hosted on GitHub and can be downloaded for free. While there is no formal pricing structure, financial contributions are nevertheless encouraged to accelerate development.

Cocos2d

Cocos2d is a robust software framework used for building games, apps, and other GUI programs. Like PixiJS, Cocos2d is open source, and developers can access its functionalities for free. Users can freely download, modify and distribute the software which underlines the ethos of affordable, shared app development.

Code Examples for PixiJS & Cocos2d

PixiJS

This PixiJS code is an interactive snippet that allows you to manipulate a bunny sprite using the mouse or touch. It requires that you’ve installed PixiJS and initialized an application accordingly. Requires a locally-hosted “bunny.png” image in project directory.

const app = new PIXI.Application({backgroundColor: 0x1099bb});
document.body.appendChild(app.view);

PIXI.Loader.shared.add('bunny.png').load((loader, resources) => {
    const bunny = new PIXI.Sprite(resources['bunny.png'].texture);
    bunny.x = app.renderer.width / 2;
    bunny.y = app.renderer.height / 2;
    bunny.anchor.set(0.5);
    app.stage.addChild(bunny);
    
    app.stage.interactive = true;
    app.stage.on('pointermove', (event) => {
        bunny.rotation = Math.atan2(event.data.global.y - bunny.y, event.data.global.x - bunny.x);
    });
});

Cocos2d

The following Cocos2d code creates a particle explosion in your scene. It requires that you have Cocos2d installed and configured, and an image named “fire.png” in the resources directory. Ensure the Cocos2d Scene and Layer structures have been implemented.

cc.Class({
    extends: cc.Component,

    properties: {
        particlePrefab: {
            default: null,
            type: cc.Prefab
        }
    },

    start() {
        this.node.on(cc.Node.EventType.TOUCH_START, this.spawnParticle, this);
    },

    spawnParticle(event) {
        const particle = cc.instantiate(this.particlePrefab);
        particle.setPosition(event.touch._point);
        this.node.addChild(particle);

        this.scheduleOnce(() => {
            particle.destroy();
        }, 1);
    }
});

The Final Showdown: PixiJS or Cocos2d?

As we reach the denouement of our comparative journey, it’s time to make the tough call.
