WEBVTT 00:00.660 --> 00:11.370 Now that we've gone through and sort of determine kind of what each major section has in terms of the 00:11.790 --> 00:21.990 data and so before we midships then or adds in the players in this guess I'll say. 00:22.500 --> 00:28.880 So let's actually start making the real types that we all need. 00:29.250 --> 00:35.150 So first thing I'm going to start with is kind of in the ship's order. 00:36.420 --> 00:40.110 Ships part it says five types listed above. 00:40.190 --> 00:40.840 OK. 00:41.000 --> 00:46.260 So we have the aircraft carrier battleship cruiser destroyer and submarine. 00:46.280 --> 00:53.260 So we have this ship type and it can only have five values. 00:53.270 --> 00:57.810 It has a very fixed and finite set of values. 00:58.130 --> 01:04.140 So that to me means that I should be using an Ina. 01:04.550 --> 01:08.870 So I'm going to make you know I'm going to call it the ship type 01:11.680 --> 01:22.150 and I'm going to actually add one more ship type and that is the ship type none. 01:22.210 --> 01:24.050 So it kind of has. 01:24.130 --> 01:32.450 There is no ship sets and you'll you'll see why I want to have this probably a bit later. 01:32.470 --> 01:40.100 But for now just know that we need none and then was going to say all the rest of ours. 01:40.210 --> 01:45.860 Aircraft carrier in it. 01:46.010 --> 01:55.420 And that I'm using s t i typically prefix all of my arms with the kind of first letter of each word. 01:55.450 --> 02:01.490 So I usually use s t from the same ship type. 02:01.940 --> 02:08.010 I'll ship this case as the cruiser 02:10.420 --> 02:12.740 steede destroyer. 02:14.420 --> 02:18.930 It's these submarine. 02:19.190 --> 02:25.010 So one of my types will be the actual ship type just like we have a pier. 02:25.290 --> 02:25.820 OK. 02:27.280 --> 02:37.120 So the next thing is what else is a ship kind of have it's just kind of cherry pick some the orientation 02:37.700 --> 02:41.240 OK so can either be vertical or horizontal. 02:41.260 --> 02:49.770 So again just like with the ship type we can only have two values vertical or horizontal. 02:49.780 --> 02:54.060 So again I say we all need enough for this. 02:54.170 --> 03:14.400 So say ship orientation type and anime's going to say so aren't all so again for ship orientation. 03:14.570 --> 03:16.390 It is so vertical. 03:18.780 --> 03:24.840 And I'm not going to have a S-O none right because I can't there's no possible way that you can have 03:24.840 --> 03:27.340 a ship that has no orientation on board. 03:27.680 --> 03:30.880 We don't need that. 03:31.810 --> 03:39.960 So now what we have in our ship is a position right. 03:40.080 --> 03:54.690 So this one is a road between a NJ which is one in 10 right and columns between 1 and 10. 03:54.690 --> 04:05.560 So how I'm going to represent this is through a struct because it has two different two different values 04:05.870 --> 04:08.010 K row and a column. 04:08.020 --> 04:14.430 And for mine I'm just going to we're just going to be integers. 04:14.580 --> 04:15.930 Ok --. 04:18.090 --> 04:18.460 Zeeshan 04:22.040 --> 04:24.640 in a row. 04:25.480 --> 04:29.760 In going to call. 04:29.910 --> 04:34.350 So all the ships will have some kind of position 04:38.540 --> 04:46.540 so the last thing we probably need is the use. 04:46.680 --> 04:54.390 It's really and of course that will just be an integer so we don't really need to make anything magical 04:54.390 --> 04:55.080 for that one. 04:55.080 --> 05:05.580 So we're actually going to move on to actually creating a ship so to say ship is a struct because it 05:05.580 --> 05:12.420 holds multiple values as a position as an orientation and has a type. 05:12.420 --> 05:14.090 Just like I showed up here. 05:14.250 --> 05:19.020 So I'm going to represent our ship with a struct. 05:19.640 --> 05:21.680 And I'm going to say ship type 05:26.580 --> 05:30.890 like that it has a size shape size 05:36.620 --> 05:45.730 ship and teach and I say you teach an 05:50.140 --> 05:58.430 and it has a position. 05:58.760 --> 06:10.610 So see how we use what we kind of broke down in the understanding phase and translate it into real types 06:10.700 --> 06:15.760 and what we'll use as real data in our game. 06:16.630 --> 06:19.840 So doing this really well. 06:19.840 --> 06:30.220 Like I said in the first section what your input is really will define how your algorithms will interpret 06:30.520 --> 06:38.740 that data and can interpret that input in a specific way to the specific data. 06:38.740 --> 06:45.040 So that's why we really do this first because this is what's really going to guide us in terms of what 06:45.040 --> 06:50.310 the algorithms should do based on this data. 06:50.650 --> 06:58.670 So this is why understanding and creating the input is usually first before actually doing the algorithms. 06:59.640 --> 07:11.730 So now that we have our ship k we should move on to our board and notice that I didn't really specify 07:11.730 --> 07:14.390 what this is yet. 07:14.400 --> 07:25.230 With our ship and and that's because it really depends on where the ship is in on the board. 07:25.270 --> 07:33.370 So really this damaged spot on the ship depends on the board position that it's at. 07:33.370 --> 07:37.540 So I'm not going to have that represented here. 07:37.540 --> 07:44.290 I'm actually going to postpone that into the board snacks. 07:44.350 --> 07:50.250 So what do we need for the board. 07:50.670 --> 07:51.210 OK. 07:51.300 --> 07:54.810 So the boards there's two different kinds of boards. 07:54.810 --> 07:57.490 One is the gas board has three states hit miss. 07:57.520 --> 08:01.720 And you know maybe none I guess. 08:01.950 --> 08:10.470 So one thing we need is kind of our guest type and we need them just like before. 08:10.610 --> 08:11.150 Type 08:13.760 --> 08:21.310 and we're going to say guess type none if we haven't guessed there right. 08:21.400 --> 08:22.520 Zero. 08:22.550 --> 08:24.240 And guess I missed. 08:24.450 --> 08:24.880 Right. 08:26.080 --> 08:34.300 And guess type hit. 08:34.320 --> 08:48.380 So those are three different states that this guess or can be and the other part is our shipboard. 08:48.450 --> 08:55.480 So what would define a ship or what type would we need. 08:55.530 --> 09:00.560 So just like the guest board the guest can only be in three states and we're going to make our guest 09:00.560 --> 09:06.490 bored out of this type and speak to the array of this type. 09:06.560 --> 09:19.810 But what about our shipboard needs a ship and it needs I guess whether it was hit or not. 09:19.810 --> 09:31.270 So for that I'm going to make a structure and call it a ship part type 09:34.030 --> 09:41.060 and it's a ship part time because this is only me one kind of square on the board. 09:41.950 --> 09:51.030 And the ship part time is going to have a ship type. 09:51.230 --> 09:52.720 We had with the ship. 09:52.850 --> 09:53.220 Right. 09:53.290 --> 09:59.630 Same type and I'm going to have a boolean saying whether it's hit or not. 09:59.700 --> 10:04.290 So is hit. 10:04.380 --> 10:07.120 So that's all is really going to have. 10:07.240 --> 10:15.920 Because if you played it before you know and your bottom board is that you have a ship placed at a certain 10:15.980 --> 10:26.570 position which is going to be set in the ship itself this position in orientation and whether it's hit 10:26.570 --> 10:26.960 or not. 10:27.080 --> 10:32.520 So that should cover that. 10:32.610 --> 10:36.870 Now now we have the player right where 10:39.200 --> 10:52.540 in each case it's going to be another struct they're and that's where we'll have a name player name 10:53.930 --> 11:01.890 and we don't know how long the names can easily see ten for now or we're going to make Hanssens for 11:02.150 --> 11:04.050 these in a second. 11:04.320 --> 11:06.770 It's going to have a number of ships. 11:07.130 --> 11:07.490 Ship 11:10.740 --> 11:12.390 and there's only five. 11:12.390 --> 11:15.430 Again I'll make a constant for this in a second. 11:16.650 --> 11:19.460 And we'll have a guest aboard. 11:19.660 --> 11:23.730 So we're going to use GPS type to make or board. 11:23.980 --> 11:28.950 And we know how big it is so we should just use a basic 2-D. 11:29.490 --> 11:30.320 Guess board 11:32.820 --> 11:39.240 and make constants from this second sets at 10 by 10 right. 11:39.320 --> 11:42.680 So here 10 grid 11:46.140 --> 11:53.650 and we have the ship or two which are going to make and ship parts part time 11:58.400 --> 12:04.480 we could design the data in a different way for this but this is what I came up with it seems pretty 12:04.610 --> 12:11.460 well. 12:11.480 --> 12:15.650 So now we have a bunch of constants here. 12:15.680 --> 12:18.040 And I kind of want to get rid of those. 12:18.200 --> 12:23.250 So I'll show you one interesting thing you can do with them. 12:23.660 --> 12:35.460 And then having kind of an anonymous and we're going to need a few kind of constants so you need an 12:35.530 --> 12:36.220 aircraft 12:39.080 --> 12:44.430 carrier size right is five spots. 12:44.440 --> 12:48.970 So it's set up here right size there. 12:49.520 --> 12:54.200 And I mean do you have for each ship ship size 12:58.940 --> 13:05.160 that and notice I'm like actually setting all the values directly. 13:05.190 --> 13:09.700 So if you if you have an anonymous you know you probably want to set them all directly. 13:09.780 --> 13:13.530 And these really just amount to constant integers. 13:13.530 --> 13:15.070 Really. 13:15.330 --> 13:24.960 That's why that's why I'm using cruiser size three destroyer sizes the 13:33.270 --> 13:33.920 green 13:36.360 --> 13:38.580 to. 13:39.360 --> 13:51.660 And our board size is 10 or so a 10 by 10 grids and the number of ships you have is five cents a ship's 13:53.640 --> 13:59.640 that and we when to say the layer name size 14:02.450 --> 14:05.860 is going to be eight characters. 14:07.820 --> 14:19.850 Because I'm going to have is like Player 1 player 2 and she's 1 2 3 4 5 6 7 plus 1 for it all character 14:19.850 --> 14:21.910 right C C string. 14:21.910 --> 14:27.830 So that's why it's eight characters and I don't have one extra one called Max ships. 14:27.890 --> 14:29.980 It's as well. 14:30.340 --> 14:38.330 And I'm going to use the aircraft carrier size for it. 14:39.780 --> 14:45.560 Because a ship is maximum size five very big is an aircraft carrier. 14:47.190 --> 14:53.420 So that's actually the data that's really all the data that we have. 14:53.580 --> 15:01.340 The and it's just I actually said all your names. 15:01.580 --> 15:02.800 Yes that's right. 15:02.820 --> 15:07.380 All right in ship's 15:11.410 --> 15:12.330 size 15:16.660 --> 15:22.090 size like this one supports It's 15:30.310 --> 15:35.940 something kind of interesting you can do with domes just have anonymous names that just have a bunch 15:35.940 --> 15:38.860 of values that it can be. 15:39.150 --> 15:42.930 And really this just amounts to being constants. 15:42.990 --> 15:55.240 So now that we've finished our data this should give us an idea of how our algorithms are going to work. 15:55.600 --> 15:57.990 So we have to have two players. 15:58.000 --> 16:08.090 Two variables of type player and these players have a name that ships their boards rank. 16:08.140 --> 16:14.150 So there's you plan for boards but there's two players two boards per player right. 16:14.230 --> 16:15.830 So each player has that. 16:15.860 --> 16:17.360 There are two different boards. 16:18.160 --> 16:18.910 And 16:21.510 --> 16:22.610 that's really it. 16:22.620 --> 16:30.150 So this is really going to determine how are our top down design and ultimately how our implementation 16:30.660 --> 16:33.000 is going to be done. 16:33.030 --> 16:38.300 So in the next lecture I'm going to go over some of the top down design.
