Extractrooms

Alpha 0.0.2 — 2026-07-18

Gameplay Changes

• Renamed the creative inventory tab from "Extractrooms Tab" to "Extractrooms"
• Added "fartnibbler" name tag easter egg for the Gaping: replaces its shriek with gaping_fart.ogg at randomised pitch, plays gaping_toot.ogg at random pitch on successful attacks and when taking damage, and swaps its texture to gaping_fart.png
• Gaping now plays its shriek sound when it kills an entity; fartnibbler variant plays gaping_fart.ogg instead
• Gaping entities now have a 0.5% chance to spawn naturally with the name "fartnibbler"
• Renamed commands: /extractrooms backrooms enter and /extractrooms backrooms leave are now /extractrooms enter and /extractrooms leave
• Reworked piston entry: the player must now occupy the piston head block itself to trigger entry, with two solid blocks in the piston's push direction — since pistons cannot physically push a player into a wall this simulates the squeeze; the 0.5-second window opens the moment the piston fires and is a one-shot event per extension
• Removed slot filler from the Extractrooms creative tab — the tab now shows only the 10 mod items

Bug Fixes

• Fixed a crash-recovery bug where a server crash at the exact moment of timer expiry could resurrect the expired run on reload, immediately killing the player again
• Fixed presence ticks only being saved at the 20-minute milestone — progress is now persisted once per second, preventing loss on unexpected shutdown
• Fixed re-entry exploit where a second entry trigger while already in a run would silently overwrite the player's return position, making escape impossible
• Fixed /extractrooms enter causing a teleport loop when used on a player already inside the backrooms — entering from inside would capture the backrooms position as the return point
• Fixed suffocation-noclip entry cancelling wall damage even when the backrooms dimension failed to load, leaving the player stuck at low health with damage permanently suppressed
• Fixed generated double chests only filling one half — the partner half is now located directly via ChestBlock.getConnectedDirection instead of a loot-table scan that failed for NBT-loaded chests
• Fixed the temporal compass being placed in a random chest slot, potentially overwriting a real item — it is now placed in the first available empty slot before the filler pass, guaranteeing it always lands without displacing loot
• Fixed the "player already has compass" check only scanning the 36 main inventory slots — offhand and armor slots are now included
• Fixed the compass LODESTONE_TRACKER component persisting after leaving the backrooms, causing the needle to spin uselessly in the overworld
• Fixed the loot item pool being reused across world sessions in singleplayer
• Fixed Gaping entities spawning naturally in the overworld
• Fixed Gaping attack animation firing on a missed hit
• Fixed Gaping shield-disable missing the block thud sound — SHIELD_BLOCK is now played manually at the point of disable since the shield is stripped before hurt() is called
• Fixed Smiler FindDarkGoal competing with ChargeGoal when both conditions were active simultaneously
• Fixed dead LookAtPlayerGoal on the Smiler being permanently unreachable due to a direct yaw override in tick()
• Fixed the timer HUD rendering over the death screen and open inventory screens
• Fixed camera shake persisting into the death screen and overworld after a dimension change
• Fixed glaring lamp buzz sound being recreated one tick later than intended due to an off-by-one in the grace period check
• Fixed RenderSystem.disableScissor() call corrupting scissor rects used by vanilla UI elements such as the chat box and boss bars
• Fixed subtle timer HUD animation jitter caused by two separate System.currentTimeMillis() calls that could straddle a millisecond boundary
• Fixed a potential crash in room template selection when all template weights summed to zero
• Fixed double chests giving multiple temporal compasses — compass placement now only runs on the primary half; the partner half is filled without triggering the compass logic
• Fixed temporal compass silently not being placed when chest item density was high enough to leave no filler slots — compass is now placed before the filler pass, guaranteeing it always gets a slot
• Fixed double chest partner half not being filled due to vanilla's loot table unpacking being triggered during the fill, wiping the chest's item storage before items could be written
• Fixed chest fill logic calling getItem() internally to detect empty slots, which triggered unpackLootTable and could corrupt container state; slot tracking now uses a boolean array instead
• Fixed block entities rendering through the Smiler — the emissive render type used for backrooms visibility does not write to the depth buffer; the main pass now uses entityCutoutNoCull (depth-writing) with a brightness EyesLayer on top to preserve the full-brightness appearance
