Simple Block Physics Fabric

This is a port of the original Simple Block Physics mod for Fabric and for newer versions of the game.

This mod implements configurable, recursive structural instability. Utilizes a functional recursive search to assess block support upon adjacent removal, avoiding chunk scans.

Warning: Structural destruction may occur. Install only in worlds where build loss is acceptable or backed up.

Features:

• Induces realistic cave-ins and building limits.
• Optimized performance via need-based physics updates.
• Prevents unsupported sky bases.
• Highly configurable support strength and iteration limits.

Mechanics Blocks lacking vertical support within a hardness-determined range will fall. Checks trigger on placement, interaction, or adjacent updates. Unstable blocks become falling entities until landing.

This mod can work server side only on a Fabric Minecraft server. So that means vanilla clients can join your Fabric Minecraft server without the mod and it will work.
