Modify Structure Seeds

  • Click the Files tab in the navigation bar on the left-hand side.
  • Locate and open the 1 spigot.yml file.
  • Changing the structure seeds will create structures like villages, swamps and so on in different positions within the same seed which will make it harder to crack.
  • Randomly change some numbers in the 2 structure seed section, a single number being changed is enough.
  • Click the 3 Save Content button to save the changes.

Change the Anti-Xray Mode

  • Enabling Anti-Xray will create “visual” corruption that prevents Xray from being effective and simultaneously makes seed cracking harder.
  • Open the 1 config/paper-world.defaults.yml file.
  • Set 2 enabled to true.
  • Change the 3 engine-mode to 2.
  • Click the 4 Save Content button to save the changes.
