transfer arrays between classes
hey,
i'm having problems transferring a 1D array from one class to another. i get the information using a class called score with GUI. but when i try to access the values in my main part of the program which is "MemoryMatch" the values are not there. but in the score class file the values are there.
the program is an assignment called memory game. the 18 images are 40*40 pics which are supposed to be matched
