Unity performance optimization involves object pooling for frequently instantiated objects, draw call batching, LOD systems, and caching component references. Use the Unity Profiler to identify bottlenecks and minimize garbage collection allocations during gameplay.

Unity C# conventions use PascalCase for public members and camelCase for private members. Prefix variables with m_, constants with c_, and statics with s_ to keep code readable and consistent across the project.

Use ScriptableObjects as data containers for data-driven design, such as item stats, enemy configurations, or game settings. They decouple data from MonoBehaviour logic, making projects modular and easier to maintain.

Prefer direct references over GameObject.Find because Find is slow and error-prone at runtime. Use TryGetComponent to safely access components and avoid null reference exceptions.

Frame drops during spawning usually come from repeated Instantiate and Destroy calls causing garbage collection spikes. Implement object pooling to reuse pre-allocated instances instead of creating new ones at runtime.
