Collision detection, contact manifolds, collision responses, determinism, and character collision handling

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?"…

Factory patterns for creating complex physics objects (ragdolls, soft bodies, vehicles, gears, mechanical systems)

Collision filtering, layer-based interactions, custom collision filters, and trigger areas

Environmental forces (wind), surface forces, and directional force application

Physics material properties including friction, bounciness/restitution, rolling resistance, and surface velocity (conveyor belts)

Use when interacting with Unity CLI from the terminal, or to control a running/connected Unity Editor from the command line — create or modify GameObjects, edit scenes and assets, inspect the hierarchy, and run C# in a live Editor instead of hand-editing…

Adds ads and monetization to a Unity game using the LevelPlay Mediation SDK (installed via the Ads Mediation UPM package). Use when a developer asks about adding ads to a Unity game, implementing rewarded, interstitial, or banner ads, setting up ad mediation,…

Edits Unity sprite properties by generating C# editor scripts using ISpriteEditorDataProvider APIs. Handles sprite rectangles, borders, pivots, outlines, and slicing operations (automatic, grid, isometric). Use when working with sprite assets, sprite sheets,…

Sets up and configures the Unity AI Navigation system — NavMesh surfaces, NavMesh agents, obstacles, links, modifiers, areas and costs. Use when creating walkable navigation meshes, adding pathfinding agents, setting up patrol routes, configuring obstacle…

Use when adding, removing, upgrading, or discovering Unity (UPM) packages programmatically from outside the Editor — headless or CI package installs via the C# UnityEditor.PackageManager.Client API, verifying package ids/versions against the Unity registry,…

Optimizes Unity 6 audio memory, CPU cost, and playback quality through correct import settings and mixer configuration. Use when the user wants to reduce audio memory usage, choose the right Load Type for short clips versus music versus ambient beds,…

Optimizes Unity 6 WebGL and WebGPU builds for smaller download size, faster initial load, and efficient browser runtime performance. Use when the user's web build is too large, stutters in a specific browser, consumes excessive battery, needs CDN/server…

3D PhysX collision and trigger diagnostics for MonoBehaviour-based Unity projects. Primary scope: OnCollisionEnter / OnTriggerEnter not firing, objects passing through each other, Physics.Raycast missing, ragdoll explosion, AddForce stops working after…

Scans the scene and audio assets to appropriately route Audio Sources into existing Audio Mixer Groups, classifying each source by what it plays. Use when the user asks about cleaning up mixer assignments, routing audio through a mixer, or which group a sound…

Optimizes Unity 6 audio memory, CPU cost, and playback quality through correct import settings and mixer configuration. Use when the user wants to reduce audio memory usage, choose the right Load Type for short clips versus music versus ambient beds,…

Optimizes Unity 6 WebGL and WebGPU builds for smaller download size, faster initial load, and efficient browser runtime performance. Use when the user's web build is too large, stutters in a specific browser, consumes excessive battery, needs CDN/server…

Add and configure in-game voice chat and text chat for Unity multiplayer games using Unity Vivox. Covers microphone setup and mic permissions on Android/iOS, voice activity detection (VAD) tuning, voice volume and mute controls in a settings UI…

Use when interacting with Unity CLI from the terminal, or to control a running/connected Unity Editor from the command line — create or modify GameObjects, edit scenes and assets, inspect the hierarchy, and run C# in a live Editor instead of hand-editing…

Sets up, configures, and debugs URP post-processing effects using the Volume framework. Use when the user asks about bloom, tonemapping, color adjustments, depth of field, vignette, motion blur, or other Volume overrides in a URP project.

Add a new subcommand to the Memory Snapshot Data Tool CLI (the .NET 10 `MemorySnapshotDataTools` exe), wiring it through CliOptions → CommandLineBuilder → Program → a Core runner, then documenting it in README.md. Use when asked to add, create, or expose a…

Generate and view Unity memory snapshot reports. Use when the user wants to analyze a Unity memory snapshot, export it to a database, validate an export against Unity golden values, or generate/view an HTML report.

Validate a Memory Snapshot Data Tool export against Unity Memory Profiler "golden" values — extract a {name}_golden.json in Unity, export the same .snap to a database, run the `validate` CLI command, and interpret the pass/fail result, tolerances, and…

Write and manage SQL queries against an exported Unity memory-snapshot database (DuckDB/SQLite), and keep the schema, views, version, and docs consistent. Use when writing/editing queries over native_objects, native_allocations, native_roots, memory_regions,…

Build, run, screenshot, and test the Memory Snapshot Data Tool — the .NET 10 CLI that exports Unity .snap memory snapshots to DuckDB/SQLite and renders an HTML report. Use when asked to run, start, build, or test the tool, export a snapshot, generate or…
