This article explains the Observer Pattern in Unity as a way to decouple game systems so one object can announce an event without knowing who listens. It covers the C# delegate and event basics behind the pattern, UnityEvent and its Inspector-friendly workflow, ScriptableObject-based event systems for cross-scene communication, and a global EventBus approach. It also introduces UniRx for more advanced reactive workflows, compares the pros and cons of each option, and warns about common pitfalls like forgotten unsubscriptions, ghost listeners, and event spaghetti.

This article explains what a Normal Map is in Unity and how it makes flat surfaces look detailed without adding polygons. It covers how Normal Maps work, why they usually look blue-purple, the differences between Tangent Space, Object Space, and World Space, and how to import, assign, and tune them in Unity materials. It also discusses creating Normal Maps from Height Maps, using them across Built-in, URP, HDRP, and Shader Graph, combining and blending multiple maps, mobile compression and size tips, common mistakes like wrong texture type or flipped green channel, baking from high-poly to low-poly models, using Normal Maps in shader code, and how they compare with Bump Map, Parallax Map, and Displacement techniques.

This article gives a full comparison of AWS S3 and Cloudflare R2, covering what each object storage service is, their main features, storage classes, pricing, free tiers, durability, availability, limits, and ecosystem integrations. It walks through real-world cost examples for e-commerce, backups, and video streaming, shows how to migrate from S3 to R2 with S3-compatible APIs and tools like Super Slurper and rclone, and explains when to choose S3, when to choose R2, and when a hybrid strategy makes the most sense.

This article introduces FMOD in Unity and explains why many game developers use it as audio middleware instead of Unity’s built-in Audio system. It compares FMOD and Unity Audio through practical cases such as UI clicks and gunshots, footsteps on different surfaces, engine sounds, and adaptive music, showing how FMOD lets Sound Designers work in FMOD Studio while Unity code only sends parameters like material type or RPM. The post also highlights FMOD’s benefits for workflow separation, memory and CPU optimization, and more dynamic, immersive audio, while noting that Unity’s default audio is usually enough for small hypercasual projects.

This article explains how Garbage Collection works in Unity, why GC spikes can cause brief frame hitches, and where hidden allocations come from in everyday code, including boxing, string concatenation, LINQ, lambdas, foreach, coroutines, and repeated component lookups. It also shows how to use Unity Profiler and Memory Profiler to find garbage, then reduce it with practical techniques like object pooling, ArrayPool, caching, pre-allocation, and struct-based data, while comparing Incremental GC with Stop-the-World GC and ending with a practical performance checklist.

This article is a practical, beginner-friendly guide to Unity Particle System in Unity 6, covering everything from the basic idea of particles and when to use the built-in system versus Visual Effect Graph, to how each major module works in the Inspector. It explains Main, Emission, Shape, Velocity/Force/Noise, color and size over lifetime, collision, triggers, sub emitters, texture sheet animation, lights, trails, custom data, Renderer settings, and the Particle System Force Field component, then finishes with scripting examples, common VFX recipes like smoke, sparks, dust, and hit effects, plus debug and performance tips for mobile-style game VFX.
