The Talk discusses ways to boost the performance of WebGL Unity games, including issues with bundle size, memory usage, and runtime performance. It suggests using Brotli for compression and non-exception support for better performance. Choosing the appropriate texture compression format and experimenting with separate builds can also help. The Talk also covers optimizing textures, models, audio, and assets by reducing build size, using compression, disabling unnecessary models, and optimizing audio quality. Unity's optimization tools and profilers are recommended for analyzing performance and memory issues.

Today's Talk discusses integrating Unity into React Native apps for game development. Unity provides a wide range of capabilities and can be seamlessly integrated with React Native. The integration involves using the Unity View component and the Unity Message callback to enable communication between the two platforms. Native plugins are created to facilitate communication between Unity and React Native. The performance of Unity in React Native apps is comparable to regular React Native apps, and the decision to use Unity or React Native depends on the app's use case and need for advanced UI and gaming capabilities.

Jonny discusses marrying WebAssembly and WebGL games with React, emphasizing the importance of choosing the right tool for game development. He introduces the Godot game engine as a powerful choice for game development and highlights the limitations of Godot. Jonny demonstrates how to combine React with Godot and showcases the ability to dynamically switch between different games on the same website. He explains the process of exporting a Godot game to the web using WebAssembly. Jonny also discusses the communication between React and Godot games and highlights the benefits and future improvements of using this approach.

Unity targets over 25 platforms and technologies, including desktop, mobile, and virtual reality. They use Emscripten to compile the engine and game logic into WebAssembly for web development. Unity can be extended with plugins to access browser features like WebXR's augmented reality mode. The speaker demonstrates intercepting Unity's calls to the browser to modify its behavior. Unity is actively working on mobile support for web export and improving documentation for extending Unity with web plugins.

Today's Talk focuses on avoiding performance and memory issues in Unity WebGL builds. The importance of managing memory and keeping the heap size small is highlighted. Techniques such as using asset bundles or an addressable system can help reduce memory usage. The limitations of garbage collection in WebGL builds are discussed, along with tips for optimizing Unity code. Tools like Backtrace can assist in debugging memory and performance issues.
