Hardheim Diving

🇭🇺 Magyar

Leírás

A Hardheim Diving egy Valheim mod, ami végre értelmes víz alatti merülést ad a játékhoz.

A játékos nem csak a víz felszínén vergődik, hanem megfelelő úszás szint után képes lemerülni, mozogni a víz alatt, oxigént használni, majd visszatérni a felszínre. A mod saját oxigén HUD-ot is ad, ami a stamina panelhez igazodva jelenik meg.

Funkciók

  • Víz alatti merülés
  • Oxigén rendszer
  • Saját oxigén csík a HUD-on
  • Fulladás sebzés, ha elfogy az oxigén
  • Úszás skill követelmény
  • Víz alatti látvány sötétedése
  • Állítható víz alatti köd
  • Vízben történő eszközhasználat engedélyezése
  • Szerver által szinkronizált beállítások Jotunn segítségével
  • Debug log kapcsoló hibakereséshez

Irányítás

  • Ctrl / Crouch – merülés
  • Space / Jump – emelkedés
  • Shift / Run – gyorsabb úszás

Fontos

A mod Jotunn-t használ, és multiplayerben mindenkinek telepítenie kell.

Szerveren a beállítások szinkronizálva vannak, tehát a szerver configja érvényesül.

Konfiguráció

A config fájl itt jön létre:

BepInEx/config/hardheim.diving.cfg

Állítható többek között:

  • szükséges úszás szint
  • maximális oxigén
  • oxigén fogyás sebessége
  • oxigén visszatöltés sebessége
  • fulladás sebzés
  • fulladás sebzés gyakorisága
  • maximális úszási sebesség
  • víz alatti sötétedés
  • víz alatti köd
  • vízben eszközhasználat
  • debug logolás

  • Custom oxygen HUD
  • Drowning damage when oxygen runs out
  • Required swimming skill
  • Darker underwater visuals
