1 00:00:01,020 --> 00:00:05,940 Welcome back in this lesson, we're going to be creating a deck of cards, so first that we need to 2 00:00:05,940 --> 00:00:10,380 do is set up a few more variables and these are some default variables that we can utilize. 3 00:00:10,800 --> 00:00:11,960 We need a deck. 4 00:00:12,000 --> 00:00:16,120 This is going to be a global variable, which will be the array that we're going to use. 5 00:00:16,440 --> 00:00:18,860 We're also going to set up a few other arrays. 6 00:00:18,870 --> 00:00:21,240 So we've got the ranks of the cards. 7 00:00:21,430 --> 00:00:24,180 And this is where you can list out all the cards that you want. 8 00:00:24,360 --> 00:00:30,030 So want all the way up to nine, 10 and then jox queens. 9 00:00:30,760 --> 00:00:36,090 And these are strings and kings and we want aces to be the largest card. 10 00:00:36,270 --> 00:00:38,130 And then there's the different suits. 11 00:00:38,640 --> 00:00:45,570 So set up another array to hold the suits and we're going to specify the suits as we've got hearts, 12 00:00:45,570 --> 00:00:48,650 diamonds, club and spades. 13 00:00:49,080 --> 00:00:55,230 So using these values, we can loop through the suits and then we can also loop through the ranks and 14 00:00:55,230 --> 00:00:56,390 build a deck of cards. 15 00:00:56,670 --> 00:00:58,820 So that's what we want to do when we start the game. 16 00:00:58,860 --> 00:01:00,510 We've got the start game function. 17 00:01:00,660 --> 00:01:05,610 We've got a global variable to handle and to take all of the deck contents. 18 00:01:05,880 --> 00:01:10,890 So next thing that we want to do when we start the game is we want to build the deck of cards. 19 00:01:11,400 --> 00:01:16,140 So build deck can be the function that will create the deck of cards. 20 00:01:16,410 --> 00:01:19,430 Let's set that function up so we start the game. 21 00:01:19,440 --> 00:01:24,000 We're building our deck and this is going to be a series of loops. 22 00:01:24,240 --> 00:01:28,740 So first that we want to do clear out the existing deck of cards as a global object. 23 00:01:28,980 --> 00:01:32,870 So so we don't have to declare it again and let's use for loops. 24 00:01:33,240 --> 00:01:41,120 So starting with AI is zero and while I is less than and looping through that suits array. 25 00:01:41,130 --> 00:01:45,150 So looping through while I is less than one, we're going to increment it by one. 26 00:01:45,270 --> 00:01:51,330 And so we need another loop inside because we've got another parameter that we're using in order to 27 00:01:51,330 --> 00:01:52,380 build the deck of cards. 28 00:01:52,560 --> 00:02:00,930 So set this one as G and looping through while G is less than ranks length as we've got both of those 29 00:02:00,930 --> 00:02:04,920 arrays that we've got to iterate through in order to build a full deck of cards. 30 00:02:05,230 --> 00:02:09,780 So once we're looping through there, let's create a blank card object. 31 00:02:09,790 --> 00:02:15,090 So this is going to be an object and this can hold all of the information that we need for our card. 32 00:02:15,330 --> 00:02:18,180 So let's set up some values for that object. 33 00:02:18,420 --> 00:02:20,060 So taking in the suit. 34 00:02:20,520 --> 00:02:28,290 So this is going to be coming in as suits and suits is controlled within eye card and we want to get 35 00:02:28,290 --> 00:02:29,770 the rank of the card as well. 36 00:02:30,180 --> 00:02:33,150 So this is held within the ranks array. 37 00:02:33,600 --> 00:02:38,500 So as we iterate through there, when we get to G, we'll output that value. 38 00:02:38,730 --> 00:02:43,740 We've also got a card value, so that can be G plus one. 39 00:02:43,830 --> 00:02:47,220 So setting this up to be whatever the value of J is. 40 00:02:47,370 --> 00:02:51,420 So as we increase in ranks, we can increase the value of the card. 41 00:02:51,810 --> 00:02:56,220 And then lastly, let's take that card and we'll push it into the deck. 42 00:02:56,280 --> 00:03:02,280 So as we loop through both of these loops, by the time we're completed, we're going to have a finished 43 00:03:02,280 --> 00:03:08,850 deck of cards and we can see that when we cancel out whatever the value of deck is. 44 00:03:09,090 --> 00:03:11,130 So let's see what that looks like and refresh. 45 00:03:11,130 --> 00:03:15,270 We hit the start of the game and that builds up our 52 card deck. 46 00:03:15,400 --> 00:03:18,910 And as you can see, we start out with all of the hearts. 47 00:03:18,930 --> 00:03:22,320 So we've got a rank of two and a value of one. 48 00:03:22,320 --> 00:03:25,280 So going up and aces are the largest values. 49 00:03:25,320 --> 00:03:26,270 They have 13. 50 00:03:26,430 --> 00:03:27,960 So they're going to be the highest card. 51 00:03:28,140 --> 00:03:30,780 You might also want to have an ace as a one. 52 00:03:30,900 --> 00:03:34,190 So it all depends on how you want to set up your deck for this case. 53 00:03:34,230 --> 00:03:38,880 What I'm doing is I'm having the ace set up as the highest card, so it's going to be three. 54 00:03:38,880 --> 00:03:45,180 So we get all of the values, all the ranks for the hearts, all the ranks for the values, diamonds, 55 00:03:45,300 --> 00:03:47,010 clubs and spades. 56 00:03:47,140 --> 00:03:52,510 And then we've got all the cards have a value in the order that they appear in the array. 57 00:03:52,740 --> 00:03:55,620 So if you want to switch these around, you're welcome to do that. 58 00:03:55,950 --> 00:04:01,890 But best practices to keep it within that sequential order so that that way you can automatically set 59 00:04:01,890 --> 00:04:03,870 the values as you loop through them. 60 00:04:03,870 --> 00:04:07,500 And it's going to make it a lot easier to compare which card is higher. 61 00:04:07,800 --> 00:04:13,740 So now that we've built a deck, next thing that we do is we need to set up the players and then deal 62 00:04:13,740 --> 00:04:14,280 the cards. 63 00:04:14,550 --> 00:04:17,310 So that's still all to come in the upcoming lessons. 64 00:04:17,340 --> 00:04:19,790 So go ahead and build a deck of cards. 65 00:04:19,800 --> 00:04:24,270 And this is another thing that we're going to do is going to shuffle this deck of cards before we deal 66 00:04:24,270 --> 00:04:25,040 it out as well.
