Godot 4.7 Baseline

• Expert patterns in this skill target Godot 4.7+ (stable, 2026-06-18).
• Consult the Godot 4.7 migration guide when upgrading projects from 4.6.
• NEVER assume 4.6 defaults (stretch mode, audio area_mask, RichTextLabel percent flags) without checking 4.7 migration notes.

Genre: Sandbox

Physical simulation, emergent play, and player creativity define this genre.

NEVER Do (Expert Anti-Patterns)

Performance & Scalability

• NEVER use individual RigidBody nodes for every block; strictly use Static Colliders for the world and reserve physics for dynamic props.
• NEVER simulate the entire world every frame; strictly process "Dirty" chunks with active changes. Sleeping chunks must consume zero CPU.
• NEVER update MultiMesh buffers every frame; strictly batch changes and only rebuild the buffer when a modification completes (e.g., player stops painting).
• NEVER use standard Godot Nodes for every grid cell; strictly use PackedInt32Arrays or typed Dictionaries to keep RAM overhead minimal.
• NEVER raycast against every individual voxel for placement; strictly use Grid Quantization (floor(pos/size)) for direct O(1) cell calculation.
• NEVER render every block face in a chunk; strictly generate an ArrayMesh that only pushes visible exterior faces to the GPU (Culling/Greedy Meshing).
