Introduction When you build games with Unity, you eventually run into the problem of managing static game data—often called master data in Japanese game development. At first, ScriptableObject may be more than enough. If your project has a few dozen items, a few dozen enemies, and only a small number of stage definitions, ScriptableObject is convenient because you can inspect and edit everything directly in the Unity Editor. As the project grows, however, the situation changes. You may end up with tables for items, characters, skills, quests, rewards, shops, gacha pools, stages, enemy placements, progression curves, and localization text. The data is no longer edited only by programmers. Planners and game designers may need to work with it in Excel or Google Sheets. At that point, the problem is no longer just choosing a file format. You need to think about questions such as: How do you load a large amount of data quickly? How do you write ID lookups and composite-key queries safely? Should CSV or JSON be parsed directly at runtime? Is it reasonable to create a large number of Dictionaries? How do you validate references between tables? How do you debug data after converting it to binary? How do you connect the source data edited by planners to the data loaded by Unity? For the runtime loading and lookup part of that problem, one strong option is Cysharp's MasterMemory . The official README describes MasterMemory as a “Source Generator based Embedded Typed Readonly In-Memory Document Database” for .NET and Unity. In practical terms, you define your schema as C# types, a Source Generator creates a typed read-only in-memory database API, and the application loads MessagePack binary data that can be queried through type-safe methods. The official README highlights performance compared with SQLite, low allocation during queries, a small database size, and generated database structures that are type-safe and IDE-friendly.

Multiplayer bugs in Unity rarely look like networking bugs. They look like "the game froze," "the player teleported," or "it worked in the Editor and broke in the WebGL build." By the time you've traced it back to the actual cause, you've usually burned an afternoon. Here are 10 issues that show up constantly in Unity networking code — WebSocket-based, Socket.IO, or otherwise — with the actual root cause and the fix. A few of these come straight out of real regression tests and commit history in socketio-unity , an MIT-licensed Socket.IO v4 client for Unity. The rest are patterns you'll recognize if you've shipped a multiplayer game. 1. Reconnect wipes your room/namespace state Symptom: Connection drops for two seconds, comes back, and the player is no longer in their room/lobby/channel — even though the server never removed them. Cause: A common (bad) reconnect implementation tears down the whole client and rebuilds it from scratch — including the list of channels/namespaces the player had joined. The reconnect "succeeds" at the transport level but silently drops application-level state. Fix: Reconnect logic should preserve subscriptions across the transport reset and only re-emit join / connect for namespaces the client already had open. If you're rebuilding the socket object on every reconnect attempt, stop — reconnect the transport, keep the namespace map. // Wrong: rebuilds everything, loses namespace state void OnReconnect () => CreateFreshEngine (); // Right: reuses the existing namespace map void OnReconnect () => ReconnectEngine (); // _namespaces untouched 2. "get_gameObject can only be called from the main thread" Symptom: Random UnityException thrown from inside a network event handler, but only sometimes — usually right when the server sends something. Cause: Your WebSocket/network library delivers callbacks on its own I/O thread. Any Unity API call ( transform.position = , Instantiate , even some Debug.Log paths) from that thread throws. Fix: Never tou

Introduction In large-scale Unity development, GC Alloc can quietly become a real problem. At first, nothing looks wrong. But as the project grows and you add more enemies, UI, master data, events, states, notifications, logs, and other systems, small allocations that happen every frame begin to pile up. LINQ is especially convenient. var aliveEnemies = enemies . Where ( x => x . IsAlive ) . OrderBy ( x => x . DistanceToPlayer ) . ToList (); It is readable. But if this kind of code runs every frame, it can become a source of both GC Alloc and CPU overhead. Unity's official documentation also recommends reducing frequent managed heap allocations as much as possible, ideally getting close to 0 bytes per frame. https://docs.unity3d.com/2022.3/Documentation/Manual/performance-garbage-collection-best-practices.html For general GC Alloc best practices, this article refers to the Unity 2022.3 documentation, because the general guidance still applies. Unity 6-specific GC behavior is covered later using the Unity 6.0 documentation. This article assumes Unity 6.0 as the minimum Unity version and explains how to choose between regular LINQ and ZLinq in production code. Unity 6.0 uses the Roslyn C# compiler, and its C# language version is C# 9.0. However, some C# 9 features, such as init-only setters, are not supported. https://docs.unity3d.com/6000.0/Documentation/Manual/csharp-compiler.html The short version The point of this article is not to ban LINQ completely. Do not use LINQ in hot paths just because it is readable. Do not assume ZLinq solves everything just because you introduced it. Those are the two main ideas. A rough guideline looks like this: Area Guideline Editor extensions, build scripts, debug code Regular LINQ is usually fine Startup, loading, initialization LINQ can be fine, but measure when data size is large Update / LateUpdate / FixedUpdate Avoid LINQ by default Code that is not per-frame but still called frequently Consider ZLinq Code that materializes res

If you have never written a line of game code and you are trying to choose between Unity, Godot, and Unreal, the internet will give you fifty contradictory answers in your first hour of searching. This article is the answer we give to people who ask us in person. We are a Unity-specialist studio. I have spent 12 years building games, including a tenure as Mobile Team on RuneScape Mobile at Jagex. Over that time I have mentored a steady stream of new developers entering the industry. We picked Unity for our commercial work, deliberately, and we will say upfront where that lens does and does not serve you. The advice below is what I would tell a friend's teenager who asked which engine to learn first, not the version where I am trying to win you as a client. Three things drive whether a beginner finishes their first game or quietly abandons it: the engine's first-week friction, the quality of the free learning material, and whether the language and tools punish you or reward you when you make a mistake. Comparison articles obsess over feature lists. Beginners obsess over whether they can get something on screen by Saturday. We are going to talk about Saturday. The 30-Second Answer If you skim nothing else, take this: Pick Godot if you want the gentlest first week. The editor is small, the language reads like Python, and you can ship a 2D game to the web in a single afternoon. Best chance of you actually finishing a project. Pick Unity if you want a future career in the games industry. Largest tutorial library, biggest job market, most transferable skills. C# is harder than GDScript but every hour you spend on it pays back in the long run. Pick Unreal if you have always wanted to make games specifically because of the visuals. Blueprints let you avoid C++ at the start, the rendering looks beautiful from day one, and the long learning curve has the highest payoff if you commit. For the rest of the article, we will explain why each of those is true, where the engines gen

As part of my game development journey, I recently created Hidden Collector , a Unity-based game where players explore levels and collect hidden items while progressing through different challenges. This project started as a way for me to improve my Unity and C# skills, but it quickly became an opportunity to learn about game design, UI systems, audio management, scene transitions, and player experience. What I Worked On While building Hidden Collector, I implemented: Player movement and interactions Collectible item systems Multiple game levels UI menus and game screens Audio and sound effects Progress tracking Game flow and scene management Challenges During Development One of the biggest challenges was making different game systems work together smoothly. Something as simple as collecting an item often required updates to UI elements, game state management, and progression systems. Debugging these interactions taught me a lot about organizing Unity projects and writing maintainable code. What I Learned This project helped me gain experience with: Unity Engine C# scripting Game architecture UI implementation Audio management Debugging and testing Most importantly, I learned that building complete projects teaches far more than following tutorials. Play the Game You can try Hidden Collector here: https://sinxcos07.itch.io/hiddencollector Screenshots What's Next? I'm continuing to improve my game development skills by building new projects, experimenting with different mechanics, and learning more about creating engaging player experiences. If you try the game, I'd love to hear your feedback.
