You dont have to give index, but in that case script will use more memory, but youll need to use index while calling that var

pawn Код:

new CityHallWasRobbedRecently[];

CityHallWasRobbedRecently[0]--;

And as VenomXNL said, first index starts with 0 not with 1, so if you have e.g 15 cityhalls, to change first one youll use index 0, to change 5th one Youll use index 4 etc...
