Cum descarc de pe TeraBox?

[_wawaaa]

Am actualizat funcțiile de gestionare a semnalelor pentru serverele Metin2 pe Windows. Acum, serverul poate fi oprit controlat la primirea semnalelor de închidere sau forțat prin combinația Ctrl+ESC (de 3 ori). În plus, am adăugat o resetare a contorului de combinații dacă trec mai mult de 2 secunde între apăsări.

De asemenea, salvarea progresului este mult mai precisă, fără delay-ul din command prompt/bash, iar activitatea poate fi reluată imediat, fără întreruperi.

Aceste îmbunătățiri vor ajuta la o gestionare mai rapidă și sigură a serverului!
