New Update Patch Notes (v0.2.4)

 

 

  • Added a welcome screen for new worlds (contains important tips for beginners).
  • Added a new advanced feature: spawn chances. Now X_17 spawns based on an advanced system of chances, making him very unpredictable and unique in each gameplay.
  • Added a new log and file system in the world save folder, making it possible to store important information for the mod and ensure persistence of all nights and X_17 activities, instead of relying on the game logs to check errors and other events.
  • Added new creepy sounds to the stalking phase.
  • Reworked X_17 behaviors such as stalking and rage.
  • Fixed exploits where players could kill X_17 easily (now his powers have increased!).
  • Optimized most of the game code for maximum efficiency.

 

 

This is another big technical update that was hard to work on, 110 days in game testing it and making sure all systems are working fine, there's still more systems that are hard to work for now, but X_17 is going exactly where it should and work will keep happening, thanks everyone for the support!

 

 

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!
