67 Entity — Release Notes (v1.1.0)

[!NOTE] Version 1.1.0 Update Overview: This release introduces native multi-version support for Minecraft 1.20.1 and 1.21.1 (Fabric), physical combat and kill mechanics with 100 HP, the Colossal Titan sighting event, revised day-based pacing, guaranteed survival damage calculations, and a unified command system.

Key Features & Behavioral Overhaul

Physical Combat Mode (100 HP)

• Combat State (10% Spawn Chance): The entity engages the player directly in melee combat rather than vanishing instantly.
• Health & Killability: The entity features a dedicated 100.0 HP pool (50 hearts) and can be damaged and eliminated using standard weapons (swords, axes, bows).
• Collision & Spacing Adjustment: Resolved an issue where entity collision caused players to be pushed into the crawling/trapdoor state. The entity now maintains an optimal melee distance (~2.0 blocks) and recoils slightly after attacking.
• Guaranteed Damage Output: Melee hits deal 1.0–1.5 damage (0.5 to 1 heart, scalable with player armor).
• Post-Kill Aftermath: Defeating the entity triggers soul fire particle effects and experience drops, temporarily blurring the player's vision with darkness and nausea before settling into silence.

Colossal Titan Sighting (5% Spawn Chance)

• Horizon Manifestation: A 25+ block tall silhouette of the entity spawns atop distant hills or open terrain (25–50 blocks away from the player).
• Environmental Atmosphere: Spawning induces a low-frequency rumble, applying temporary darkness and slowness status effects.
• Observation Window: The Titan remains stationary on the horizon for up to 60 seconds (1200 ticks). Approaching within 15 blocks causes it to dissolve in smoke particles.

3D Flash Encounter (20% Spawn Chance)

• Direct Visual Encounter: The entity materializes directly within the player's line of sight at a distance of 2.2 blocks in full 3D space.
• Fixed Duration: Stands facing the player for exactly 1.0 second (20 ticks) before disappearing with particle and sound effects.

Progressive Day-Based Pacing

• Day 1 Safe Period: Day 1 (world time < 24,000 ticks) is completely peaceful. No entities, chat messages, or sign placements will trigger.
• Event Frequency: Beginning on Day 2, ambient occurrences scale to an average interval of once every 2 to 3 in-game days (~48,000 to 72,000 ticks).
• Silent Sign Placement: Environmental signs ("67 / I was here") are placed silently behind the player without triggering block placement audio.

Multiplayer Dual-Targeting

• On servers with two or more active players, manifestations select two distinct random players simultaneously rather than prioritizing only the primary server host.

Behavior Probabilities

Unified Command Interface: /67 (or /sixtyseven)

All legacy commands (/spawn67, /67config, /67test) have been consolidated into a structured command system:

• /67 (or /67 menu) — Opens the interactive chat control panel with clickable buttons.
• /67 spawn <attack|chase|flash|giant|observe> — Spawns the entity in a specified behavior mode.
• /67 event [attack|chase|flash|giant|observe|random|dual] — Manually triggers an ambient manifestation event.
• /67 flash — Triggers the 1-second 3D flash encounter.
• /67 giant — Spawns the Colossal Titan on the distant horizon.
• /67 screamer — Executes the full jumpscare overlay with audio and heavy damage.
• /67 sign / /67 door / /67 whisper — Manually tests environmental atmospheric effects.
• /67 health [amount] — Checks or sets the health value of the nearest 67 entity.
• /67 clear — Despawns and cleans up all active 67 entities across all loaded dimensions.
• /67 status — Outputs current day count, time of day, estimated time until next event, and active entity counts.
• /67 config — Displays the configuration and preset menu.

Technical Improvements & Compatibility

• Multi-Version Architecture: Standardized cross-compilation for Fabric 1.20.1 (Java 17) and Fabric 1.21.1 (Java 21) within a single unified project repository.
• 1.20.1 Vertex Rendering Correction: Restored the mandatory buffer commit call (.next()) in the 1.20.1 renderer pipeline, resolving an issue where the entity was invisible on 1.20.1 clients.
• Mixin Compatibility: Removed conflicting Java 21 mixin constraints on Java 17 runtimes.
• Survival Damage Invulnerability Bypass: Reset hurt resistance timers (timeUntilRegen) on hit events to ensure survival players consistently receive health reduction from attacks and screamers.
