3D Physics Engine Architecture & 0.5m Voxel Sockets
All Will Fall (All Parts Connected / tinyBuild, April 3, 2026) is a physics-based survival city builder where gravity, downward mass transfer, and lateral torque govern colony survival. Buildings are constructed on a 0.5m voxel socket grid where every placed block adds physical mass and recalculates structural stability in real-time.
The core diagnostic tool is the Structural Stress Overlay (color-coded from Green at <40% stress, Yellow at 40-75%, Orange at 75-100%, and Red pulse above 100% indicating imminent catastrophic collapse). Vertical load transfers down uninterrupted column paths to the foundation; cantilever overhangs exceeding allowable moment arms trigger cascading collapse loops that plunge entire multi-tier settlements into the ocean.
The Golden Rule of Frontier Engineering: "Build Wide First." Establish broad horizontal bases across multiple pylon lines before attempting vertical expansion into high-altitude industrial tiers.
Pneumatics (v1.3.2), Ocean Hydrodynamics & The Citizen Triad
The August 2026 (v1.3.1 / v1.3.2) update introduces Pneumatic Pipes, Vents, and Floating Bubble Storage Depots with buoyancy offsets, mitigating foundation drag while requiring sealed socket connections to prevent missing-path bubble alerts.
Ocean hydrodynamics subject foundations to submerged erosion (60% load capacity penalty for blocks below the high-tide line) and lateral storm wind-shear (adding +12% torque per floor level for structures above 6 floors). Deploying seabed Deep Anchors (120kg capacity) into bedrock eliminates water erosion penalties and provides stable anchors against 50ft swells.
Colony logistics require balancing the Citizen Triad: Workers (raw scrap/wood foraging and smelting), Sailors (kelp/fish food extraction and marine salvage), and Engineers (foundation maintenance and structural stress repairs) to avoid the fatal Starvation-Maintenance collapse loop.
