What's new

Changelog — Breximatica v1.8.0

Visual & GUI Enhancements

1. Solid Block Model Color Tinting

  • Translucent block overlays are now tinted with the selected preset color (Cyan/Lime/Red) while preserving 60% of the original texture detail.

2. Outlines Toggle

  • Added Outlines: ON/OFF button. Combine with Solids toggle for wireframe-only, tinted-only, or both.

3. Layer Up/Down Buttons

  • Re-added - Layer / + Layer buttons to the Visuals column.

Namespace Rename

  • Full rename from schematichelper → Breximatica (packages, GUI class, config file, key bindings, translations).

Block Orientation & Placement Engine

4. Universal Block Rotation

  • Look-towards rotations for doors, beds, fence gates, bells, 16-directional standing banners/signs, anvils (90° CCW offset).
  • Multi-block filters: Automatically skips upper halves of doors/double plants and bed heads.

5. Neighbor Click-Face Validation

  • Wall-attached blocks (ladders, wall signs/banners/torches, tripwire hooks, end rods, shulker boxes, lightning rods): click facing.getOpposite().
  • Hoppers & cocoa beans: click facing direction.
  • Buttons, levers, grindstones: UP for ceiling, DOWN for floor, facing.getOpposite() for walls.
  • Standing torches & standing signs: restricted to floor placement (DOWN only).

Sign Support

6. Automatic Sign Text Auto-Fill

  • When the autopilot places a sign and the SignEditScreen opens, the mod automatically fills in the text from the schematic and closes the screen instantly — no manual typing needed.
  • Sign text is parsed from all three formats: .litematica (TileEntities), .schem (BlockEntities), and .nbt (nbt compound tags).
  • JSON text components ({"text":"Hello"}) are automatically decoded to plain text.
  • Sign text positions are correctly rotated when the schematic is rotated with rotateClockwise90().

Scaffolding & Supports

7. Persistent Scaffolding Memory & 20s Delay

  • Support blocks are tracked in config/breximatica.json — survives restarts and disconnects.
  • 20-second minimum lifetime before cleanup — prevents place/break vibration loops.
  • BFS connection validation: scaffolds used as bridges are preserved until destination blocks are built.

8. Reach Range Validation

  • Support blocks are only broken when the player is within reach distance. Out-of-range scaffolds stay in memory until the player gets closer — no blocks forgotten.

9. Prioritized Horizontal Bridging

  • Horizontal bridges and single-block attachments are tried before vertical pillars, reducing total blocks placed.

Physics-Aware Placement

10. Gravity-Affected Block Support (Sand, Gravel, Concrete Powder, Anvils)

  • Detects FallingBlock instances and checks if the block below is air.
  • If schematic has a block below: defers placement until the correct block below is built first.
  • If schematic has air below (floating block): places a temporary scaffold underneath first.

11. Hanging Lantern Ceiling Block Placement

  • Detects LanternBlock with hanging=true and checks if the block above exists.
  • If the ceiling block is missing: automatically places the correct schematic block from the upper layer first, even when building layer-by-layer.
  • Lantern placement is deferred until the ceiling block is in place.
  • isSupported() treats hanging lanterns without a ceiling as unsupported.

Two-Phase Block Placement

12. Potted Plant Support (Flower Pots)

  • Blocks like potted_poppy, potted_oak_sapling, potted_cactus, etc. are now fully supported.
  • Phase 1: Places an empty flower_pot at the target position.
  • Phase 2: Right-clicks the empty pot with the correct flower/plant item (FlowerPotBlock.getContent()).
  • New interactWithBlockAt() helper method for right-clicking existing blocks in the world.
  • findNearestMissingBlock correctly identifies potted plants as missing targets and checks for FLOWER_POT in inventory.
