Gravity Mod — v1.00.0 Beta

Minecraft 1.20.1 · Forge

This is a major beta toward the 1.0 update. Many systems have been rewritten. Behavior will feel different from older builds.

Note: This mod was previously developed under the name Structural Collapse (structural_collapse). It is now Gravity Mod (gravity_mod). Older worlds, inventories, and configs are supported through automatic remapping where possible.

Name change

• Display name is now Gravity Mod
• Mod id is now gravity_mod
• Items from structural_collapse remap to gravity_mod automatically
• Existing structural_collapse config files are copied to the new id on first launch if needed
• Removed legacy custom blocks (old support beams, etc.) are ignored so worlds still load

Support & stress

• Support is no longer a simple safe/unsafe zone
• Distance and support quality now scale how fast stress builds
• Blocks inside a support range gain stress more slowly; blocks outside gain stress faster
• Each material has its own support range
• Supports with little solid ground under them act as weak supports
• Blocks with more faces open to air are slightly weaker
• Earthquakes and other environmental effects add to stress instead of bypassing it
• Collapses and collapse spread are driven by the stress system
• Stress is calculated over a larger area so big caves feel more consistent

Stability Scanner

• Fully rewritten scanning system
• Modes: stress view, live stress, and support view
• Live stress updates while you hold the scanner (with a size limit for performance)
• Scans can be pinned so the overlay stays when you put the scanner away
• Clearer color scaling for stress levels
• Support mode uses a blue color scheme
• New item textures for idle and active states
• Crafting recipe included
• Mode switching no longer shows an enchantment glint

Stress Profile Inspector

• New inspection tool for exact numbers (not just colors)
• Mode A: detailed stats for a single block
• Mode B: select two corners to inspect an area
  • Top-down stress map
  • Flat and vertical slice views
  • Area statistics
• Copper / mechanical style UI
• Custom textures for each mode
• Crafting recipe included

Config

• Redesigned config menu
• Separate gameplay presets and performance presets
• Performance presets: Potato, Light, Balanced, Heavy, Ultra
• Settings that depend on another option only appear when relevant
• Most stress, support, environment, and performance options are configurable
• Presets can be switched in-game via commands

Commands

• Stress simulation command to apply time-based stress quickly for testing
• Commands to change presets without opening the config screen

Sounds

Collapses

• New stone collapse sounds
• Short crack when a block starts falling
• Impact sound when it hits the ground
• Louder / larger-sounding impacts when many blocks fall together
• Quieter on the surface; fuller underground
• Currently plays for stone-like blocks (dirt, gravel, wood, etc. still silent)

Earthquakes

• New earthquake rumble system
• Three intensity mixes (small, medium, large) based on quake strength
• Strength is compared to your configured maximum, so average quakes sound medium
• Volume also scales with strength
• Rumble segments shuffle so each quake sounds a bit different

Other

• Removed old support immunity behavior
• Cleaned up outdated config options and old sound assets

Notes

• Designed with multiplayer in mind (server-side stress and collapses)
• Still a beta: balance, performance, and edge cases may change
