SecurityCraft (Fabric)

Added

• Ownership — every reinforced block, door and trapdoor now remembers the player who placed it. Only the owner (or a team-mate) can break it; for everyone else it behaves as unbreakable, and the owner's own breaking speed is configurable. The owner's name shows in the Jade tooltip.
• Universal Owner Changer — transfers a SecurityCraft block you own to another player.
• Universal Block Modifier, and the Customize screen it opens — the in-game screen for every block option (search radius, delays, allowlist/denylist behaviour, and so on), rebuilt against the original's layout and wording. Includes the per-module enable/disable toggle.
• The SecurityCraft Manual — the in-game handbook, with its own port title page, the patron list, a page for every block group and the in-book recipe grid.
• Passcode-protected Chest, Barrel, Furnace, Smoker and Blast Furnace — vanilla storage and smelting behind a passcode. The chest keeps its own artwork and pairs into a double chest only with another of the same owner; the furnace family lights up and cooks exactly like vanilla.
• Electrified Iron Fence and Fence Gate — the shock fence and its gate.
• Fake Water and Fake Lava — look and flow exactly like the real fluids (they even borrow water's and lava's textures and names), until something walks into them.
• Reinforced redstone machines — reinforced hopper, dispenser, dropper, observer, sticky and regular pistons, cauldrons (empty, water, lava, powder snow), lectern and chiseled bookshelf, each keeping its vanilla logic.
• Crystal Quartz set — the reinforced cyan-tinted quartz blocks, stairs and slabs.
• Secret Signs — standing and hanging signs whose text only the owner and allowed players can read.
• Around 60 more reinforced blocks — carpets, glazed terracotta, ladder, lanterns, chain, end rod, cobweb, scaffolding, lever, redstone lamp, grass block, podzol, mycelium, sea lantern, bookshelf, tuff, pale oak, resin, and the reinforced copper bulb, copper grate and lightning rod, bringing the reinforced set to just over 500 blocks.

Fixed

• Binding a mine to the Mine Remote Access Tool could throw you out of your world. Once the tool held at least one bound mine, picking it up or moving it around the creative inventory made the server answer with Failed to decode packet 'serverbound/minecraft:set_creative_mode_slot' and close the connection; saving a world with a bound tool in it failed the same way. The bound-mine component insisted on exactly six slots and, on the 1.21.5+ builds, could not write an empty one at all. The list is now padded or trimmed back to six wherever it is read and empty slots serialise cleanly. An unbound tool was never affected. Shipped early as the 2026-08-31 hotfix. Reported by ZloyGnom.
• Most block items showed their raw id (item.securitycraft.reinforced_stone and the like) on 1.21.3 and newer. Minecraft 1.21.2 made a BlockItem stop borrowing its block's name unless it is told to; every SecurityCraft block item now opts in, so they read as Reinforced Stone again.
• Passcode-protected barrels would not open. Right-clicking did nothing, because the block returned the wrong interaction result and 1.21.2+ only falls through to the "open" handler on a specific one. Keypad and keypad chest were unaffected.
• The reinforced grass block rendered wrong — the grass on top came out grey instead of green, the dirt sides and the Jade preview came out solid black, and the item was tinted purple. The grass overlay now takes the biome grass colour (times the reinforced tint), the block is on the cutout render layer so its see-through pixels stay see-through, and the item icon matches.
• The reinforced doors, trapdoors, furnace windows, electrified fences, reinforced glass and fake water all rendered their transparent parts as solid black on 1.21.6 and newer. Minecraft 1.21.6 removed both the Fabric render-layer hook and the model field the port relied on; the terrain render layer is now set directly for those blocks.
• The SecurityCraft Manual was broken on 1.21.6+: it crashed the game the moment it was opened ("Can only blur once per frame"), then — once that was fixed — showed no text at all, because 1.21.6 stopped drawing text passed a fully-transparent colour. Its body text was also being drawn bold with a shadow, its page-turn arrows and recipe grid were missing, its icons were black and the patron-link button was a magenta square. All fixed; the manual matches the original.
• The module editor drew its title and player list in invisible text on 1.21.6+ — the same transparent-colour problem as the manual.
• The creative menu showed missing-texture ("checkerboard") items on 1.21.4+, because that version added a per-item model file the port had not generated. Every item now has one, and the reinforced-block tint values were corrected so tinted items are not rendered fully transparent.
• The Mine Remote Access Tool screen drew a missing-texture background on 1.21.5 (four GUI textures had never reached that branch), and its "detonate" button showed a plain TNT item instead of the explosion icon on 1.21.6+.
• Reinforced blocks now break with the right tool and drop correctly regardless of the tool used, matching the original's always-drop behaviour — the Fabric port had no equivalent of the Forge hook the original uses, so the flag is cleared on the block properties instead.
• The reinforced door's window and the electrified fence gate texture are mapped correctly instead of rendering black or garbled.
• Fake water and fake lava are named Water and Lava everywhere, including the JEI tooltip, so they cannot be told apart from the real thing.
• Chat messages from SecurityCraft blocks use the original's colours again.
• The reinforced scaffolding got its item back, so it can be stacked downwards while held like vanilla scaffolding.
• Recipes and block/item tags were converted to the formats Minecraft 1.21.2+ expects, so the reinforcing recipes and the mining-tool tags load on every version.

Changed

• The mod's author is now credited as Verkos (the Fabric port author); the original SecurityCraft team stays listed as contributors, and the MIT licence is unchanged.
