I do understand you, problem is, I'm not sure if I can use English in my code (you know, I'm not exchange student or anything, so why should I use it). Anyway, for now more than half of code commands is in English.
Translation of rest:
@echo off
echo laivu musis.
echo 2 zaidejai.
echo Ar norite pradeti?
echo jei taip spauskite, bet kuri klavisa, jei ne ctrl+c.
pause>null
// 2nd line: naval battle
// 2 players
// do you wabt to start?
// if so press anything, if not ctrl+c //these are kinda default
echo pasirinkite:
echo T - Pradeti zaidima
echo N - Baigti zaidima
CHOICE/c:TN
//echo pasirinkite == choice:
//T == start game
//N == end game
echo pirmas zaidejas iveda savo 10 laivu. 1 koordinate = 1 laivas
//first player enters his fleet of 10 ships 1coordinate equals 1 ship
prn1 like message1 or msg1
:prn1
echo tokiu koordinaciu but negali, iveskite is naujo.
goto firstplayer
//echo such coordinates does not exist, repeat.
where u can see rem saudymas means shooting, on other echos it just says that either it's hit or missed. I believe other commands are in english already.
Anyway, I think i just need to delete variable if it's hit and next time on picking coordinates to output message which would say that i already hit that and it no longer exist. but then still how to check weather there are any variables left?
hope this helps a bit.
