Component authoring patterns and best practices for Unity PhysicsCore2D
High-level patterns and gameplay strategies for destructible objects in Unity PhysicsCore2D — slicing mechanics, fragmenting on impact, sprite-based destructible systems, debris cleanup, performance budgeting. Use for "how should I design destructible X?" questions. For the PhysicsDestructor type API and worked code examples see unity-physicscore2d-destructor; for raw member signatures see unity-physicscore2d-destructor-api.
