Dynamic Structural Physics

Overview

This project introduces a comprehensive gravity and rigid body physics engine to the game's blocks. It completely removes the default floating behavior of unsupported blocks. Instead, when a block or a connected structure loses its supporting foundation, it converts into a physical entity, reacting to gravity, mass, and collision.

Core Features & Mechanics:

• Dynamic Gravity & Collapse: Chopping the bottom of a tree or destroying the base of a building will trigger a structural update. The unsupported blocks above will fall dynamically to the ground rather than floating in mid-air.
• Material-Based Shatter System: Falling structures interact with the terrain based on their specific material properties:

1. Fragile Materials: Blocks like dirt, leaves, and glass have a low impact tolerance. If they fall from a high distance and hit the ground at high speed, they will shatter and break apart.
2. Hard Materials: Blocks like stone, solid wood, and metal have a high shatter tolerance multiplier. They will survive hard impacts and settle on the terrain as solid, intact chunks.
3. Water Buoyancy Simulation: The physics engine calculates water dampening and mass. Lightweight falling objects (such as leaves) will experience buoyancy and float calmly on the water's surface rather than sinking or bouncing erratically.
4. Chunk Limit Processing: To maintain stability during massive collapses, large falling structures are divided and processed into maximum 5x5x5 physical bodies.
5. Built-in FPS Optimization: The engine is heavily optimized for performance. It features a strict 12ms time budget for physics calculations per tick. Additionally, active falling entities are capped at 100. If a massive chain-reaction collapse occurs, the system safely culls excess falling blocks to prevent frame drops, memory spikes, or crashes.

How to Use in Game

• Apply the behavior and resource packs to your world.
• You must enable "Experimental Gameplay API" features in your world settings for the scripts to execute.
• Break the bottom-most block of any structure or tree, and watch the physics engine take over
