Echo Protocol

Echo Protocol 0.5.0-beta.2 — Hotfix 2

This update focuses on fixes discovered during extended external survival testing on Minecraft 1.21.11.

Fixed

• Improved Echo visibility while keeping the target player's real Minecraft skin clearly recognizable.
• Reduced excessive transparency so Echoes are much easier to notice during normal gameplay.
• Echoes now use only very light transparency while remaining visually distinct from normal players.
• Fixed Memory Echoes frequently selecting idle, AFK, crafting, or mining segments instead of meaningful movement.
• Memory-based Echoes now prioritize continuous movement recordings when appropriate.
• Fixed Echoes repeatedly standing still and staring at the ground.
• Improved initial pitch/orientation for independent Echo types.
• Fixed Mimic movement issues caused by recorded absolute coordinates.
• Fixed Echo grounding on slabs and uneven terrain.
• Fixed Corrupted Memory progression being granted before a properly observable manifestation.
• Improved observation checks for several Echo-related advancements.
• Fixed rejected and unobserved events consuming excessively long cooldowns.
• Fixed failed/discontinuous events potentially leaving the Event Director locked.
• Added faster bounded retries after failed or unobserved manifestations.
• Improved Echo appearance sound readability.
• Improved cleanup and lifecycle handling for natural Echo events.
• Preserved collision-aware movement and blocked-route safety.
• Preserved real player skins and classic/slim model support.

Testing

• 61/61 automated regression tests passing.
• Tested on Minecraft 1.21.11 with Fabric.
• Final build tested through Prism Launcher.
• Tested using natural survival gameplay and the real Event Director rather than relying only on spawn/debug commands.
• Dedicated Fabric server startup and shutdown verified.

Compatibility

• Minecraft 1.21.11
• Fabric
• Java 21
• Fabric API required

Note

This is a bug-fix and polish update for 0.5.0-beta.2.

Larger gameplay additions and new horror behaviors are planned for a future beta.
