unity-physics-queries

What problem does it solve?

This Skill addresses common and often subtle bugs in Unity's physics query system (Raycast, SphereCast, OverlapSphere, etc.), preventing silent failures and ensuring accurate detection.

Core Features & Use Cases

• Correct Query Selection: Guides users on choosing the right physics query for their needs (e.g., Raycast vs. OverlapSphere).
• Allocation & Performance: Demonstrates efficient use of NonAlloc queries and buffer management to avoid garbage collection.
• Edge Case Handling: Explains gotchas like trigger interaction defaults, hit ordering, and backface detection.
• Use Case: Debugging why a ground check isn't working, or why a bullet seems to pass through an enemy.

Quick Start

Use the unity-physics-queries skill to understand the difference between SphereCast and OverlapSphere.
