What problem does it solve? It provides a dedicated worker agent specification for implementing the building/construction system in the Bakırköy BR Unreal Engine 5 project, covering build piece placement, material gathering, ghost previews, structure editing, turbo build, and destruction mechanics with consistent design constraints. ## Core Features & Use Cases - Build Piece System: Defines 4 piece types (Wall, Ramp, Floor, Half-Wall) with 3m grid snapping, support validation, and cascading destruction rules. - 3-Material Economy: Specifies Moloz, Tuğla, and Çelik materials with exact harvest rates, stack limits, HP values, and hardening times. - Edit System: Owner-only structure editing (door, window, half-cut, arch) with 0.4s animation and replicated mesh swapping. - Use Case: When a developer needs to implement or modify the BRBuildingComponent, BRBuildPiece, or BRBuildPreview C++ classes, this skill supplies the exact design values and constraints to follow. ## Quick Start Ask the agent to implement the build piece placement logic in BRBuildingComponent following the 3-material building system specification.
