Stencil

0.2.0-alpha - 2026-09-21

Added

• Search box on the settings screen that filters every tab's options by name.
• Hotkeys can be bound to mouse buttons, including side buttons.
• Ghost blocks render as the chosen block model instead of a coloured box.
• Tools: Left Ctrl plus wheel selects Place blocks, Place all, Change block or Extend facing side; right click runs it. Each tool has its own hotkey (toolPlaceAll = V, toolChangeBlock = C, toolExtendSide = Left Alt) for direct use. Both place tools take the block from the inventory, or conjure it in creative mode.
• spawnProofSingleLayer option: never offer a ghost on top of a placed block or the chosen block, so fills stay one block thick.
• spawnProofLowGaps option: mark one-block-high spots too, where short mobs can still spawn.
• Change block refuses blocks that mobs can still spawn on, judged by the game's own spawn rule, so full blocks and top slabs are rejected with a message.
• ghostBlockAlpha option (Visuals tab) sets how see-through ghosts are.
• Choosing a light-giving block (torch, lantern, glowstone) makes the spawn proof ghosts a plan for the fewest lights that leave no dark spawnable spot: a lattice on open ground and extra lights where terrain blocks the glow. lightPlanRadius (32) sets how far the plan reaches and torchMaxSpawnLight the light level mobs still spawn at.
• commandReach option: with cheats or op, raises the block interaction range by /attribute while the overlay is on so far ghosts can be placed, and resets it after.

Changed

• Hotkey capture: Escape cancels and keeps the old binding, Backspace or Delete clears it.
• spawnProofGhostColor is now #RRGGBB; opacity moved to ghostBlockAlpha.
• Licensed under GPL-3.0; the mod metadata said MIT before.

Fixed

• Ghost colour changed nothing: only its alpha byte was applied and the tint was always white. Ghosts now take the chosen colour, and a six-digit value no longer turns them invisible.

• Button, lever and grindstone ghosts previewed as the wall variant and hung in the air; previews now use the floor placement.

• Dropdown options ignored left click and cycled on right click, because Minecraft 26.3 numbers mouse buttons from 1.

• Number, colour and text boxes now commit on Enter or when clicking elsewhere, and show the clamped value.

• Dev client on GNOME Wayland had no title bar; the run config now uses X11.

• Scanning stalled the frame with a light block chosen; the scan and light plan now run on a background thread and the ghosts update when it finishes.

0.1.0-alpha - 2026-09-21

Added

• Fabric client mod scaffold for Minecraft 26.3 on JDK 25.
• Config system with Litematica-compatible option names, persisted to config/stencil.json.
• Hotkey system with chorded bindings and duplicate-binding warnings.
• Settings screen with tabs, boolean, cycle, text and hotkey editors; a cancelled hotkey capture keeps the previous binding.
• Spawn proof overlay: ghost blocks on mob-spawnable positions in a square or circular area around the player, with a Layer mode for filling a flat level. Radius is adjustable per mode by hotkey or scroll wheel, and single sides can be extended up to the radius limit.
