Getting Started with Cocos Creator

Getting started with Cocos Creator is straightforward enough for those with existing HTML5 canvas game development experience. After downloading the editor from the official website, you can run through the initial startup guide which walks through the creation of your first Cocos Creator scene.

Like Unity and Unreal Engine, Cocos Creator is built around a hierarchical node system which defines the logical relationships between different game objects and components. Manipulating nodes in the Hierarchy panel and positioning them visually via the Inspector makes building scenes intuitive.

Cocos Creator uses JavaScript for its scripting language, so those with JavaScript skills can immediately begin applying that knowledge for creating mobile apps with HTML5 and planning game logic. For quicker iteration, you can also utilize the integrated Chromium DevTools debugger directly within Cocos Creator. Out of the box, you get access to several resource management tools like the Asset Manager along with the multi-resolution Sprite Editor for 2D graphics.

Animation timelines can be constructed visually via clip sequencing while texture atlases group assets logically and efficiently. For rapid previewing on different platforms, the Simulator function allows quick testing on mobile, desktop and web.

Key Features for Powerful HTML5 Game Coding

Under the hood, Cocos Creator provides numerous professional-grade HTML5 game development services beyond its easy-to-use editor and workflows. These capabilities make it possible for small teams or solo developers to build fairly complex 2D titles across a range of genres.

For example, integration with the Box2D and Chipmunk physics engines makes realistic movement and collisions possible without heavy coding requirements. As games get more ambitious, Cocos Creator’s flexible node system helps manage greater numbers of sprite entities along with their behaviors and reactions. Developers can script visual effects like parallax backgrounds that react to player movement contributing to immersive, polished experiences.

Cocos Creator also provides Party Systems for team coordination along with user account services via Cocos Cloud. This enables important post-launch capabilities like push notification support, leaderboards, achievements and analytics while handling user accounts across platforms. Monetization can also be built-in by leveraging Cocos monetization SDKs.

For mobile-targeted games, Cocos Creator allows you to deploy and test iterative builds directly to iOS and Android devices. Integrations with Xcode and Android Studio streamline this process for native running and debugging.

Building Cross-Platform Games

A major selling point for Cocos Creator is its cross-platform publishing abilities. After developing your game for Web (HTML5), you can then leverage the same code base and assets for building to native platforms like iOS and Android. Under the Platforms panel, you simply select your intended deployment target and configure the necessary build settings.

For Android, Cocos Creator integrates directly with Gradle for generating custom project files catered to your game. Import these projects into Android Studio to sign your APK then publish to the Google Play Store. iOS deployment works similarly via XCode project generation, allowing Apple signing for App Store distribution. Besides mobile, Cocos Creator allows publishing to Mac, Windows, Facebook Instant Games, some VR platforms and even command-line interfaces.

The key things to understand are:

  1. Core game logic written in JavaScript works consistently across targets
  2. Some renderer differences exist across platforms which may require optimization
  3. Assets compatible on Web may need adjustment for native environments
  4. Additional performance testing required relative to platform specs.

While not a seamless “one-click” process, Cocos Creator absolutely simplifies what would normally be very cumbersome cross-platform workflows. The benefit is you get to focus HTML5 game making on a single code base instead of making fully separate native projects. When designed thoughtfully, the game can then be deployed to multiple platforms with relative ease.

Optimizing Game Performance

A downside of HTML5 and WebGL targeting relative to native development is that game performance can be inconsistent across devices and platforms. Factors like GPU, memory, browser choice and feature support all play a role. This means optimization must be given high priority throughout the HTML5 game platform when using Cocos Creator.

Some best practices include:

– Testing progressively on low to high spec devices

– Monitoring FPS and memory consumption

– Simplifying scenes and reducing draw calls

– Grouping sprites into batched nodes

– Using texture atlases appropriately

– Compressing audio and images

– Fine-tuning Garbage Collection

– Working around platform HTML5 limitations.

Thankfully, Cocos Creator provides decent tooling for profiling including FPS meters, draw call counters and full engine logging. Third party solutions like Stats.js can also be integrated for deeper profiling. Testing across browsers helps uncover areas for optimization relative to standards support. Reducing the performance gap between HTM5 game and native rendering remains an ongoing effort.

While achieving flawless 60fps animation across all platforms can be difficult, Cocos Creator certainly narrows the gap significantly. Performance milestones hit via Web build optimization further carry over well when porting to native iOS and Android runtimes. This unified process makes it more practical to ship high quality games via HTML 5 development while still tapping into multiple markets.

Showcase of Games Built with Cocos Creator

Since launching in 2015, Cocos Creator has accumulated an impressive portfolio of games highlighting its capabilities for HTML5 dev. These releases showcase polished visuals and fluid performance on Web approaching desktop and mobile native quality standards.

Then games like Blade Idle by Taptap Games demonstrate the potential for simplified 2D art to shine through excellent execution of style. Its clever mix of automation, progression and clicker feedback loops has garnered millions of downloads thanks in part to Cocos multiplatform deployment.

The level of visual fidelity found in titles like Sol Invictus by developers Above The Clouds further pushes boundaries. The seamless mix of 2D and 3D graphics integrated with traditional RPG elements shows immense attention to detail.

For Western developers, Cocos Creator was used to ship award-winning narrative adventure game Horace by indie studio 505 Games. Its emotional storytelling shines through professional use of music, voice acting and visual metaphor rivaling indie darlings like Limbo.

These are just a sample of the outstanding work being produced with Cocos Creator across genres, art styles and gameplay formats. As a mature HTML5 engine, it manages to bridge much of the gap between browser and HTML5 app development services.

Developing HTML5 Games for Android Devices

With over 2 billion active Android devices, the Android platform presents a massive opportunity for distributing HTML5 games. The web standards based approach of HTML5 allows you to create game canvas HTML5 for cross platforms that can reach Android users alongside iOS and desktop players accessing the same content via their browsers. However,Optimally tailoring your HTML5 game for the Android experience does require some specialized considerations during HTML5 game programming.

Getting Set Up for Android HTML5 Development

The first step is ensuring your HTML5 web development environment can deploy builds to Android devices for testing. As HTML5 native apps are browser based, all that is needed is a modern standards compliant browser like Chrome or Firefox with web debugging tools. Leveraging Chrome DevTools is highly recommended due to Android webviews being based upon Chromium foundations.

For integration into app store deployment, wrapping your HTML5 game inside a thin native shell provides the bridge to the Google Play Store. Tools like Apache Cordova, CocoonJS and Intel XDK simplify the complexities of generating these wrappers. This allows your game to be released as a standard Android app using HTML5 and Javascript.

Understanding Android Device Limitations

Unlike the closed iOS ecosystem, Android devices vary wildly in terms of processing power, screen sizes and GPU capabilities. This directly impacts rendering speeds for advanced HTML5 games using Canvas or WebGL. Always be prepared to scale down visual quality through simplified assets, reduced draw calls and particle effects to achieve smooth frame rates. Lower powered Android devices also tend to be more constrained by memory, so optimize loading processes and limit any memory leakage.

Tuning Touch Controls

Given smaller touch screens and variable input sensor quality, fine tuning controls is crucial so your HTML5 game plays comfortably on Android. Sensitivity testing helps dial in maximum speeds for swipe recognition and dynamic joystick motions. Also be prepared to scale up certain UI elements like buttons to ensure adequate touch target size.

Integrating Android Specific Features

For a native-like experience, your HTML5 game can leverage Android device APIs through cross-platform libraries like PhoneGap. This enables the use of system notifications, vibration, device orientation and other hardware functionality. Ensuring offline support through service workers and the Cache API also provides reliability similar to native HTML5 apps.

Optimizing Mobile Performance

Making HTML5 games run fast on mobile is hard. They can slow down and get choppy compared to native apps. So test for speed issues early when making your HTML5 games mobile. Look for ways to simplify what’s on screen. Have basic backgrounds. Limit lots of moving objects and flashy effects. Use tricks like sprite batching. This makes graphics faster to draw. Also design for average mobile devices, not just top new phones. Avoid complex collisions, big textures, and tons of particles if possible.

The key is to profile FPS rates from the start. Optimize game assets and code to maximize frames per second. An HTML5 game studio like eJaw follows mobile best practices. Their HTML5 mobile application development use neat tricks for buttery smoothness. Even on average devices with limited memory and older GPUs. Well optimized HTML5 games can perform nearly as well as native apps. It just takes extra testing and fine tuning for the best mobile experience possible.

Building and Distributing Android Games

Once your game meets performance milestones across test devices, use Emscripten and Docker containers to streamline command line builds of your HTML5 application for packaging into a .apk file. Sign the package through Android Studio to enable app store publishing. With the Google Play Store now supporting HTML5 app submissions alongside progressive web apps, leverage open web technologies to maximize your distribution and build Android app with HTML5 CSS Javascript.
