FullStop! 🛑 Changelog

2.0.0 — Minecraft 1.20.1 (Forge)

A full rework of the mod on a new codebase.

Data-Driven Block Behaviors

Block physics and behaviors are now defined by block tags under data/fullstop/tags/blocks/, so datapacks and other mods can customize them without code changes:

• fullstop:fragile — blocks that shatter easily and count as nearly zero hardness on impact (glass, ice, snow).
• fullstop:soft_landing — blocks that absorb most of an impact (hay).
• fullstop:cushioning — blocks that soften an impact (wool, leaves, moss, …).
• fullstop:phaseable — blocks that fast-moving entities pass through instead of colliding with (leaves).
• fullstop:engulfing — phaseable blocks that swallow fast movers (sand, gravel, snow): heavy drag bleeds off their speed, and once slowed they become lodged inside and must dig their way out.
• fullstop:gravity_affected — blocks that fall like sand when unsupported.
• fullstop:sticky — gravity-affected blocks that cling to any touching block (slime, honey), so they only fall when floating completely free.
• fullstop:kinetic_immune — entity types that never take kinetic damage (bosses, flying/agile/soft-bodied mobs).

Unsupported (Gravity-Affected) Blocks

• Added a data-driven unsupported block system: blocks tagged fullstop:gravity_affected become falling blocks when no longer connected to the world. Columns collapse one block at a time, just like sand. This system will be expanded in future updates.
• Slime and honey blocks now fall when unsupported. As fullstop:sticky blocks, they count a neighbor on any face as support, so they can still hang from walls and ceilings.

New Block Interactions

• Entities colliding with engulfing blocks (sand, gravel, snow) at high speed become lodged inside and must dig their way out.
• Fast-moving entities phase through passable blocks such as leaves instead of taking impact damage.
• Kinetic block breaking: fragile blocks shatter on high-speed impact.

G-Force & Blackouts

• Expanded G-force and blackout mechanics with new status effects tied to sustained G-force.
• Revamped G-force visuals and sounds, with smooth eased blackout effects.
• Blackouts can now occur while drowning (blackout extended to air supply).
• Blackout effects now render correctly in third person.
• Added new enchantments and status effects.

Environmental Damage

• Added atmospheric damage.
• Added underwater pressure damage.

Physics & Performance

• Improved physics calculations, including reworked collision detection and bounce edge cases.
• Improved overall performance.
• Tweaked the sonic boom cooldown.

Configuration

• Added new configuration options, including enableGravityBlocks to toggle the unsupported block system.

Bug Fixes

• Fixed broken death messages, including entity collision death messages.
• Fixed entities dying on impact when getting into or out of bed (e.g. villagers at sunrise).
• Fixed item entity velocity desync.
• Fixed audio filtering for the G-force effect.
• Fixed vertical impact damage.
• Fixed velocity increasing when sliding along a wall.
• Fixed entity riding and dismount edge cases, and prevented mounting while flying.
• Numerous other bug fixes, improvements, and changes.
