=Managing Cards= [[user:Alyce|1310404623]] [[toc|flat]] ---- =Arrays!= Whether you are creating a card game with images from a DLL, with bitmap images, or a text game, you'll need a way to keep track of the status of the cards. Arrays provide a perfect way to do this. =Single or Double?= Consider using a double-dimensioned array, since it is the most flexible. The first dimension holds the index of the card and the second dimension holds information such as it's x location, y location, face-up/face-down status, disable/enabled status, in play/removed from play status, suit, color, value, etc. =Creating the Array= An array with two dimensions must be DIMmed. If you are using a 52-card deck, the first dimension will be 52. The second dimension size depends upon the game and its pertinent information. Let's create an example. [[code format="lb"]] dim deck$(52,6) 'deck$(x,1) : rank, A,2,3...J,Q,K 'deck$(x,2) : suit, hearts, spades, diamonds, clubs 'deck$(x,3) : side - face UP or face DOWN 'deck$(x,4) : in play Y or N 'deck$(x,5) : x location of upper left corner 'deck$(x,6) : y location of upper left corner [[code]] =Filling the Array= We can use loops or nested loops to fill the array at the start of the game. Tge following code creates a string for the rank values. It then fills the array in a loop, using the word$() function on the string. It ends with a print routine so that we can check our work. [[code format="lb"]] dim deck$(52,6) value$ = "A 2 3 4 5 6 7 8 9 10 J Q K " for m = 1 to 4 rank$=rank$ + value$ next for i = 1 to 52 deck$(i,1) = word$(rank$,i) next 'check to see how it is filled: for j = 1 to 52 print deck$(j,1) next [[code]] You'd fill your arrays according to the specifications of the game under construction. =Retrieving the Info= You can retrieve the info in the same way it was printed in the example above. [[code format="lb"]] idx=32 'array index to query cardRank$ = deck$(idx,1) [[code]] ---- [[toc|flat]]
