What's new

New Update Patch Notes (v0.3.5)

  • Added an independent safety system for X_18 blackout events.
  • Improved X_18 grab, blackout, and cave horror stability.
  • Improved loaded chunk handling for nearby chests, torches, and cave/base interactions.
  • Reduced unnecessary client log spam from repeated system messages.
  • Improved internal logging and error handling for horror systems.
  • Fixed the X_18 blackout sequence so the player’s vision always returns properly.
  • Fixed X_18 grab behavior to avoid trapping players on the black screen.
  • Fixed several logic issues related to X_17 and X_18 AI behavior, spawning, and event flow.

 

This is a focused stability update based on feedback from recent X_18 testing and important fixes for horror event systems.


Developer Notes

 

X_18’s cave grab and blackout event should now be much safer and more stable. The black screen now has additional fail-safe handling so players should not get stuck without vision after the event.

 

X_17’s torch extinguishing and item stealing systems were also adjusted to behave closer to their original design again, while still working better with the current Hytale API.

 

Note: this mod is still WIP, and much content and changes will be done with feedback and my vision of this project. Please be free to give any suggestion or comment about anything you may wish. Thanks!
