This problem can disrupt the user experience, as players may not receive any feedback while waiting for the data to load. In this guide, we will explore a solution that allows you to load large JSON files without hanging your game, ensuring a smoother experience for your users. The Problem Imagine you're working on a mobile game that loads a significant amount of data—about 17MB for an array structure, in JSON format. You may have used SimpleJSON for parsing, but as you noticed, using it caused the game to hang for up to 30 seconds. This delay not only frustrates players but also affects perceived performance. Here's a quick summary of your current approach: You load the JSON file using TextAsset. You parse the file content using SimpleJSON. The heavy lifting happens on the main thread, leading to unresponsive gameplay during those 30 seconds. Proposed Solution The key to resolving this issue lies in offloading the JSON parsing work from the main thread to a background thread while keeping user feedback active. Using C# Threads Step 1: Set Up Your Coroutine Start by creating a coroutine that will act as your file loading mechanism. Here's a revised version of your original coroutine: [[See Video to Reveal this Text or Code Snippet]] Step 2: The Background Loading Function Create a method to handle JSON parsing in another thread. The following loading method will be invoked on a separate thread while keeping the main thread responsive. [[See Video to Reveal this Text or Code Snippet]] Conclusion By utilizing multi-threading techniques in C# , you can significantly enhance user experience when loading large JSON files in Unity. This approach allows you to keep the game responsive while parsing the data in the background. Key Takeaways Use C# threads to handle intensive operations. Keep user feedback mechanisms like sliders active for better user experience. Ensure thread safety with ConcurrentQueue for main thread interaction. By following these steps, your game can load large datasets efficiently, providing users with both the data they need and an enjoyable experience.
