unity-physicscore2d-queries

To perform a Unity Physics2D raycast for line of sight, you cast a ray from an origin to a target and process the closest hit. This single-shot query uses QueryFilter configuration to apply layer masking and sort hits for precise gameplay decisions.

The best way to detect overlap areas for AOE damage in Unity 2D is using single-shot overlap queries. These pattern-driven tests check for collider intersections within defined trigger zones, utilizing QueryFilter and layer masks to filter targets.

You should use shape casts instead of raycasts for projectile sweeps when you need to detect collisions along a volume's path rather than a thin line. Shape casts sweep geometry through world space to find time-of-impact interactions.

You configure QueryFilter and layer masks for Physics2D distance queries by defining which layers to include or exclude before executing the query. This setup ensures AI awareness and closest-point calculations only process relevant geometry versus world variants.

This Skill focuses on single-shot Unity Physics2D queries rather than batched execution. For bulk or batched queries that process multiple casts and overlaps simultaneously for performance, it references a separate batching Skill for those specific scaling needs.
