Structural validation and damage systems for Three.js building games. Use when implementing building stability (Fortnite/Rust/Valheim style), damage propagation, cascading collapse, or realistic physics simulation. Supports arcade, heuristic, and realistic physics modes.
Use this skill when working with Mass Entity, MassEntity, Mass AI, MassProcessor, MassFragment, MassTag, MassObserver, MassSpawner, MassCrowd, Mass ECS, entity archetype, ForEachEntityChunk, FMassEntityQuery, FMassEntityManager, ISM crowd, or large-scale entity simulation in Unreal Engine. See references/mass-entity-patterns.md for processor and observer templates. See references/mass-fragment-reference.md for built-in fragment types.
Build and script 2D tilemaps in Unity 6: the Grid + Tilemap components, the Tile Palette, tilemap colliders, rule tiles, and runtime SetTile/GetTile painting. Use when painting tile levels, adding a TilemapCollider2D, using rule or animated tiles, generating tilemaps from code, or when the user mentions Unity tilemap, tile palette, rule tile, or Grid.
SpriteKit API reference — all node types, physics body creation, action catalog, texture atlases, constraints, scene setup, particles, SKRenderer
Hexagonal grid mathematics, coordinate systems, pathfinding, and spatial algorithms for hex-based games. Use when implementing hex grids, calculating hex distances, finding neighbors, pathfinding on hex maps, spreading effects across hexes, or converting between coordinate systems. Triggers on requests involving hexagonal grids, hex coordinates, A* on hex maps, or hex-based game mechanics.
End-to-end Stake game development workflow for math, RGS contract, frontend playback, and compliance gating. Use when building or updating Stake games, defining game modes and RTP targets, validating generated books/index metadata, validating event streams, integrating frontend event playback, implementing RGS communication and replay mode, or preparing publication checks including social-language and jurisdiction requirements.
Building decay and upkeep systems for survival games. Use when implementing timer-based decay, Tool Cupboard patterns (Rust-style protection radius), resource upkeep costs, or server performance management through automatic cleanup. Balances gameplay and server health.
Use this skill when making a Phaser 4 game responsive or handling display scaling. Covers ScaleManager, scale modes (FIT, RESIZE, EXPAND, ENVELOP), auto-center, fullscreen, and browser resize handling. Triggers on: ScaleManager, responsive, resize, fullscreen, FIT, scale mode.
Use this skill when working with Phaser 4 utility functions, actions, alignment, grid layout, or batch operations on game objects. Triggers on: align, grid layout, actions, set operations on groups of game objects.
Pre-Production validation — build a production-quality end-to-end build to confirm the full game loop is achievable before committing to Production. Run after GDDs, architecture, and UX specs are complete. Produces a PROCEED/PIVOT/KILL verdict that gates the Pre-Production → Production transition.
Expert blueprint for sandbox games (Minecraft, Terraria, Garry's Mod) with physics-based interactions, cellular automata, emergent gameplay, and creative tools. Use when building open-world creation games with voxels, element systems, player-created structures, or procedural worlds. Keywords voxel, sandbox, cellular automata, MultiMesh, chunk management, emergent behavior, creative mode.
