WEBVTT 00:01.030 --> 00:10.690 In this lecture I want to get the Gheen sort of set up and have everything drawing so you start with 00:10.690 --> 00:11.740 getting everything set up. 00:11.830 --> 00:15.150 So we're going to need two players 00:18.060 --> 00:23.000 overseas or player type and here to 00:27.780 --> 00:32.600 and we're going to do the initialize the player. 00:33.150 --> 00:34.200 We didn't actually 00:36.830 --> 00:45.620 didn't actually break it down in the top down design but I didn't do it because we were doing it right 00:45.620 --> 00:46.000 away. 00:46.020 --> 00:48.850 So initialize 00:51.730 --> 01:03.830 we're in one it was going to name him Player 1. 01:04.260 --> 01:05.960 It's where 01:13.590 --> 01:14.260 to 01:17.240 --> 01:19.370 like so. 01:19.460 --> 01:20.870 So it's 01:25.260 --> 01:30.030 a lead function declaration this year. 01:30.880 --> 01:39.230 And we're going to pass by reference because right change the player's state in here we're going to 01:39.230 --> 01:41.600 need a concert char. 01:41.600 --> 01:44.240 Star player 01:47.100 --> 01:53.650 and we're gonna have to string copy it into the player's array. 01:53.660 --> 01:55.900 So we're going to Sturckow. 01:56.220 --> 02:02.210 And by the way if we you should include the utils so that we have it. 02:02.220 --> 02:03.780 I've already done that here. 02:04.230 --> 02:11.190 But if you haven't you should pause the video and include the utils in your project. 02:11.500 --> 02:15.840 So string. 02:16.070 --> 02:20.830 So we have that. 02:21.000 --> 02:32.230 Now let's implement this. 02:32.380 --> 02:36.050 So how are we going to do this. 02:36.070 --> 02:43.240 So let's say if player name is not equal to no pointer 02:47.730 --> 02:55.300 is to use string copy. 02:55.410 --> 03:05.420 And in fact we should probably also check to see and read the story when player name is greater than 03:05.420 --> 03:05.950 zero. 03:08.140 --> 03:15.350 And if that's true then we're going to copy it into our player name array. 03:18.460 --> 03:18.730 So 03:23.260 --> 03:32.330 in now we want to actually set all the ships correctly for the player. 03:32.470 --> 03:33.280 OK. 03:33.480 --> 03:47.040 So to do this we will say say player datt Shep's zero. 03:47.650 --> 03:48.940 So be the 03:51.620 --> 03:55.850 was going to be the aircraft I guess. 03:56.040 --> 03:58.630 So type 04:01.640 --> 04:02.690 reaching for this 04:12.930 --> 04:17.130 kind of carrier 04:20.000 --> 04:21.740 where ships 04:24.030 --> 04:24.820 0 04:27.560 --> 04:27.850 teach 04:30.340 --> 04:34.730 size should be your 04:37.780 --> 04:42.130 carrier size. 04:43.400 --> 04:44.720 Merda chips 04:47.120 --> 04:47.620 of 04:50.460 --> 04:52.420 Rouche. 04:53.120 --> 05:01.170 So the position and the orientation of this doesn't matter at the start. 05:01.170 --> 05:01.600 Right. 05:01.670 --> 05:06.080 It's a Roekel zero and seeing things here 05:10.420 --> 05:13.720 you call them 05:16.820 --> 05:20.140 ships hero 05:23.420 --> 05:25.460 station again doesn't matter. 05:26.520 --> 05:30.180 Because we're going to set them all in our set up. 05:30.310 --> 05:36.680 So and we have to do this a bunch of times right now do it for each aircraft carrier. 05:36.690 --> 05:44.280 So it would be nicer if we actually had it for each ship or should say no aircraft carrier would be 05:44.280 --> 05:45.790 nice if we had a function to do. 05:45.810 --> 05:51.000 So let's actually make a function and so it's a national as 05:54.380 --> 05:56.020 ship. 05:56.140 --> 06:14.390 And it will actually take the ship by reference and it will take the ship's size and the type. 06:14.520 --> 06:14.860 Right. 06:14.900 --> 06:19.550 That's the only Those are really only two things that really mattered and what just kind of set them 06:19.550 --> 06:21.270 all to be like this. 06:21.660 --> 06:24.500 So to copy this 06:30.650 --> 06:33.990 to or she's going to copy this whole thing 06:37.100 --> 06:45.130 cut it in and so instead of pulling to ships zero of this ship 06:50.040 --> 06:50.410 that 07:16.930 --> 07:26.570 and now all they have to do is just set the type and size ship type. 07:26.670 --> 07:32.360 So in this space ship site it's. 07:32.570 --> 07:39.380 So now when it's initialized player instead of just kind of directly doing it we'll just call the function 07:39.380 --> 07:41.570 because we have to do it for each ship so. 07:42.070 --> 07:47.590 And it will be in it in this ship. 07:47.790 --> 07:53.180 Ship's zero. 07:57.040 --> 07:59.700 Ear. 08:00.100 --> 08:02.510 It's in the 08:06.210 --> 08:06.730 carrier 08:09.600 --> 08:13.590 K and we just need to do this for each one. 08:16.790 --> 08:17.090 So 08:21.640 --> 08:25.650 ships of one will be our battleship 08:36.510 --> 08:43.040 and of to the cruiser 08:54.090 --> 08:55.350 three or destroyer 09:09.760 --> 09:10.620 or submarine 09:26.850 --> 09:27.590 and that's it. 09:27.600 --> 09:33.040 So that will now initialize all our other players. 09:33.120 --> 09:34.830 So we only have two. 09:35.070 --> 09:36.910 So that should be good. 09:37.350 --> 09:41.130 So let's right the main kind of lube. 09:41.400 --> 09:57.350 You know I do this is a name in with the players want it to and while want to do a 10:05.750 --> 10:07.170 copy this 10:09.740 --> 10:10.720 is peer 10:13.980 --> 10:18.670 turns nothing you will pass by reference 10:21.480 --> 10:22.610 here. 10:24.200 --> 10:24.940 Day. 10:25.250 --> 10:28.030 And we want to do that said 10:33.820 --> 10:44.130 Lillian that many times shouldn't be too magical what we how we implement that. 10:44.150 --> 10:45.450 So let's just implement. 10:45.470 --> 10:47.870 Want to play again right now just the way 10:50.210 --> 10:56.450 so is your input. 10:59.070 --> 11:06.850 This and will have comments char input. 11:12.970 --> 11:14.770 Yes or no. 11:15.180 --> 11:16.220 Did before 11:18.770 --> 11:20.390 it was input. 11:20.440 --> 11:38.060 It's of course to get character and would you like to play again and slash and that's And will the error 11:38.060 --> 11:49.710 string so it's actually to find it's years and when it's just fine it various their context should just 11:55.160 --> 11:56.360 here straight 12:00.130 --> 12:01.550 but error 12:06.620 --> 12:08.390 as I get 12:21.580 --> 12:37.820 past there and say valid input and two and remember are lower case and upper case stuff did for so and 12:38.150 --> 12:44.970 will turn input equal to Y. 12:45.890 --> 12:49.360 So there's what I want to play again. 12:50.460 --> 12:51.610 So in either way. 12:51.610 --> 12:53.900 So we're actually done with the main now. 12:53.980 --> 12:58.160 And all we have to do is concentrate on play again. 12:58.180 --> 13:05.980 So let's let's do the kind of set up for. 13:05.990 --> 13:08.840 But we won't do the entirety of set up or. 13:09.270 --> 13:21.200 I don't think this lecture will do the dry it so let's start at. 13:21.460 --> 13:33.190 So I have to set up words for player 1 and set up order for player to 13:36.490 --> 13:39.350 and that's all we're going to get. 13:39.520 --> 13:46.520 In this lecture footplate game so he said it's 13:52.610 --> 13:53.980 here. 13:54.100 --> 14:04.330 So here we're going to make void's your attorney thing and I guess we'll pass it by reference. 14:04.540 --> 14:08.160 Well OK. 14:08.830 --> 14:10.580 It was our declaration 14:13.400 --> 14:14.560 in down here. 14:14.600 --> 14:17.960 Well actually it's some of it. 14:18.140 --> 14:21.560 All. 14:21.640 --> 14:27.550 So how did this work. 14:27.790 --> 14:33.030 See set up or so clear the board. 14:33.100 --> 14:35.690 So that's the first thing to do. 14:36.970 --> 14:41.270 So again we'll have another function called clipboards 14:43.990 --> 14:52.900 or boards of player and she passed comments actually no need to change. 14:52.940 --> 14:55.280 So that's the reference again 14:58.040 --> 15:00.340 here boards 15:02.670 --> 15:05.490 and how will this work. 15:05.560 --> 15:14.140 So all we have to do is say for our equals zero for that row. 15:14.280 --> 15:17.750 Ours is less than the board size right. 15:19.060 --> 15:21.030 Size or you just find that's 15:23.680 --> 15:25.750 and go through all the column s 15:28.970 --> 15:30.520 so board size 15:37.080 --> 15:40.770 and what we have to do is clear the board. 15:40.770 --> 15:45.070 So if we access the start with the board. 15:45.450 --> 15:51.360 So the gas board of R and C should be Jiechi none right. 15:52.700 --> 15:57.580 So this will set every element in this 2d array to be G-d not. 15:57.620 --> 16:07.910 So the player effectively hasn't guessed here yet is what this is saying and like Likewise the shipboard 16:10.460 --> 16:17.710 here this should be actually the ship type. 16:17.710 --> 16:20.110 This is a ship part this whole thing. 16:20.720 --> 16:26.600 And the ship type should be as not. 16:26.770 --> 16:33.640 Right because there's no this really means there is no ship here at this location. 16:34.190 --> 16:40.180 And also there's two elements to this array structure. 16:40.280 --> 16:45.300 So is hit is false right. 16:45.910 --> 16:50.650 Nothing was hit here and there's no there's nothing here in first place. 16:51.040 --> 16:52.860 So that'll clear the boards. 16:52.880 --> 16:54.210 That's what that means. 16:55.350 --> 17:06.110 And if you go back you set up boards to clear boards of the player 17:09.450 --> 17:11.520 right now is the very first step. 17:11.520 --> 17:24.430 We said we appear and then we essentially loop through all the ships and then draw the board each time. 17:24.620 --> 17:31.190 Given the current ship and then place all that right. 17:31.340 --> 17:38.900 So I think what we'll do for the rest of this lecture is just draw the board and we'll skip kind of 17:39.020 --> 17:40.520 the rest of it for now. 17:40.880 --> 17:44.490 So what we're going to do is clear the boards and then just draw the board. 17:44.600 --> 17:47.890 So draw forward it's 17:50.720 --> 17:56.130 player. 17:56.290 --> 17:57.470 Is this 18:00.870 --> 18:03.490 here knock or turn or anything. 18:03.610 --> 18:04.980 Just draw function. 18:07.950 --> 18:14.400 And in this case now we're never going to change it so I can put Konst where I can change the player 18:14.400 --> 18:15.310 as we drive. 18:15.550 --> 18:16.910 OK. 18:17.230 --> 18:24.740 In here it's a drop or it's. 18:24.840 --> 18:27.390 So how will this work. 18:27.390 --> 18:39.980 So what I want to do is have the I want the columns all marked and the rows are marked so the rows go 18:39.980 --> 18:47.270 from 8 to J and the columns go from 1 to 10 and I want to have both boards kind of display next to each 18:47.270 --> 18:47.830 other. 18:49.940 --> 18:50.780 So 18:53.680 --> 19:01.960 this one is going to be a little bit hand-wavy won't really break it down in terms of the explanation 19:02.050 --> 19:13.090 exactly but I'm just going to use star typing wreathing we need and I'll sort of explain after or explain 19:13.090 --> 19:14.210 a little bit on the way. 19:14.220 --> 19:15.750 Mostly when after. 19:15.760 --> 19:24.540 So essentially what I want to do is draw the columns row. 19:24.670 --> 19:30.110 So this is all the kind of one to 10 for each one. 19:30.190 --> 19:38.760 So you don't even have this function but you'll see in a minute and then draw the 19:42.930 --> 19:43.570 gain 19:51.330 --> 19:57.090 and you'll see why did this. 19:57.290 --> 19:57.710 You know 20:02.750 --> 20:05.130 and I'm going to go through all the rose 20:17.570 --> 20:21.630 and you're going to need a separator line. 20:27.060 --> 20:27.400 Or 20:31.850 --> 20:38.140 it's then you're probably encouraged in what I'm doing here but just just try to follow follow along 20:38.410 --> 20:42.350 and you'll see exactly how this works. 20:42.370 --> 20:44.050 It all kind of come together. 20:47.970 --> 21:00.900 Normally when you're doing drawing it's very error prone and usually takes a few iterations get it correct. 21:02.220 --> 21:02.820 So 21:06.910 --> 21:07.650 here 21:14.100 --> 21:23.470 ch. 21:23.800 --> 21:24.330 Yes 21:28.460 --> 21:30.810 there. 21:30.880 --> 21:36.310 So essentially what I'm doing is draw a separate line which will kind of look like 21:39.850 --> 21:42.040 it looks like this to you. 21:43.780 --> 21:50.810 So it'll kind of look like this except for each three dashes we'll have another plus. 21:50.880 --> 21:54.410 So each cell will look like this. 21:59.720 --> 22:05.080 And does it look like an empty cell on the board. 22:05.210 --> 22:05.900 OK. 22:05.900 --> 22:11.900 So they'll have three spaces in the middle space will actually draw something to represent like the 22:11.900 --> 22:14.290 ship or whether it was hit or not. 22:14.430 --> 22:15.390 OK. 22:15.440 --> 22:16.030 So 22:18.840 --> 22:21.290 that's what I'm doing here. 22:24.100 --> 22:27.350 And these are all functions of that it's like. 22:27.500 --> 22:29.010 Ouch and all 22:32.010 --> 22:37.270 in half to try another separate line for the last separator. 22:42.390 --> 22:42.660 CH 22:47.190 --> 22:48.600 one more step. 22:54.540 --> 22:56.140 In another and 23:01.640 --> 23:05.830 and up here. 23:05.880 --> 23:09.800 So let's start drawing kind of lines and stuff. 23:09.810 --> 23:10.570 So 23:15.610 --> 23:22.250 right for let's say Boyd separator line 23:25.850 --> 23:57.320 this see how much. 23:57.500 --> 24:08.570 So this will essentially just make all the kind of all the cells essentially for all of the columns 24:09.430 --> 24:13.180 they and the next one 24:18.540 --> 24:19.140 rule 24:28.400 --> 24:30.410 is pretty similar. 24:34.400 --> 24:37.820 See Ciro's this or size 24:40.880 --> 24:44.190 plus an 24:46.990 --> 24:49.930 things this will actually draw the name of the thing. 24:55.310 --> 24:55.860 It's 25:06.680 --> 25:17.040 answer that deals with those most of it and I would just need a few more functions which is in fact 25:17.450 --> 25:21.260 let's show what this looks like right now. 25:25.560 --> 25:28.850 It's the first 25:42.110 --> 25:48.770 Roger. 25:48.860 --> 25:50.300 So you can see 25:54.990 --> 25:58.610 it's not quite right. 25:59.120 --> 26:12.960 So haven't done all of the kind of the vertical bars for each one and these are not centered correctly. 26:14.380 --> 26:17.490 But that will be easy to fix. 26:18.070 --> 26:20.030 Let's continue on with the East. 26:20.150 --> 26:25.070 It's this simpler. 26:25.370 --> 26:31.100 So it's those two and those I didn't have to declare these functions. 26:31.100 --> 26:36.160 They didn't really just have to be above where you use them. 26:36.620 --> 26:46.250 So I will actually declare them above anyway but just so you know you don't have to declare every function. 26:46.250 --> 26:50.100 You just need to define them before you use them. 26:50.150 --> 26:58.920 Essentially wise was possible plane to you so your void 27:02.830 --> 27:03.600 draw 27:07.490 --> 27:08.600 or 27:14.740 --> 27:15.680 change it. 27:15.720 --> 27:16.100 CH 27:19.420 --> 27:22.120 In true. 27:22.390 --> 27:29.230 So this will actually fill in what goes here essentially and all rows. 27:29.980 --> 27:38.770 So char name routine row plus a 27:42.850 --> 27:44.600 because the row. 27:44.790 --> 27:51.120 For example if it is 0 0 plus a is a and then one plus a is b. 27:51.160 --> 27:51.670 Right. 27:56.240 --> 27:57.000 In 28:00.330 --> 28:09.110 this and then will go through all the columns C zero. 28:09.180 --> 28:11.140 So this order is 28:14.560 --> 28:27.100 plus and will say see out space and then what we want right now I'm going to print out another space 28:27.130 --> 28:34.630 but this is this is going to change this part because we want is whatever is the representation of that 28:34.630 --> 28:36.360 ship. 28:37.090 --> 28:39.760 And show you exactly what I mean this second 28:43.340 --> 28:48.030 this way. 28:48.310 --> 28:53.470 And similarly for the gas I'm actually going to copy 28:55.880 --> 28:56.390 this 28:59.120 --> 29:04.400 void drawer and I guess sporter 29:08.820 --> 29:09.610 the player 29:14.330 --> 29:14.560 in the 29:20.420 --> 29:21.180 K. 29:21.440 --> 29:22.280 So 29:27.020 --> 29:34.970 now once again. 29:35.200 --> 29:37.190 And I said OK. 29:37.750 --> 29:44.170 So see how this almost looks like what we want right. 29:44.630 --> 29:54.900 So you'll see each there is a a a b c f g h i j for each row. 29:55.080 --> 29:57.050 And so this will be kind of the 30:00.050 --> 30:08.650 this will be kind of the player ship board and this will be his guess word. 30:08.990 --> 30:09.350 OK. 30:09.360 --> 30:20.070 So that's why I met whatsoe'er what I meant with them being next to each other at an early age change. 30:21.700 --> 30:26.080 SCHROCK Holmes So how come this is not working. 30:34.250 --> 30:35.450 Missed something. 30:38.870 --> 30:40.480 Toothpastes here. 30:44.100 --> 30:45.370 Toothpastes here. 30:46.860 --> 30:49.810 Three spaces two spaces 30:52.480 --> 30:55.640 Jesus. 30:55.880 --> 30:58.230 And then again they're real. 30:58.490 --> 30:59.900 So this is two spaces. 30:59.900 --> 31:00.930 This is two spaces. 31:00.930 --> 31:03.100 This is one space. 31:03.860 --> 31:08.280 So you'll notice I'm drawing both players boards. 31:08.300 --> 31:18.720 So what we need to do now is I need to fill in what the representation of each ship will be. 31:18.730 --> 31:19.080 OK. 31:19.100 --> 31:29.520 So if I have an aircraft carrier down here basically or what I want to see is a right and it's hit then 31:29.520 --> 31:36.020 it's going to be a like if it's at here star a. 31:36.560 --> 31:40.440 And then that's that's why I chose the names that I did for the 31:43.440 --> 31:53.360 ships because you'll notice that none of these start with the same character a b c d s. 31:53.470 --> 31:57.670 Ok so I did that on purpose actually. 31:58.470 --> 32:10.170 So let's actually get the representation for the ships so that 32:17.180 --> 32:19.310 so strong this 32:22.000 --> 32:32.000 will say char get the ship in station counts. 32:32.210 --> 32:32.860 We're 32:36.840 --> 32:44.210 in and I'll pass it the row. 32:44.570 --> 32:46.140 So this second 32:52.730 --> 32:59.190 row you know it the column and if it hits 33:02.000 --> 33:08.840 the player dock ship board because we're checking the ship board because as the whether it's hit or 33:08.840 --> 33:19.700 not intromission column dot is hit then we're going to return a star character. 33:19.820 --> 33:25.620 This is going to represent hit. 33:27.340 --> 33:33.190 And then here if player dot ship board 33:36.100 --> 33:46.730 row and column ship type you get up you could probably also use a switch statement if you want. 33:47.280 --> 33:49.770 Not going either. 33:52.620 --> 33:53.080 You're 33:58.430 --> 34:05.190 and return it's in a k a A for aircraft carrier. 34:05.300 --> 34:07.370 If player docked ship or 34:10.760 --> 34:12.560 row and column 34:15.600 --> 34:16.470 ship type 34:19.240 --> 34:21.590 is the bell ship 34:25.170 --> 34:32.940 to turn it be it will be if player ship word 34:36.490 --> 34:41.150 to cone ship type 34:44.180 --> 34:46.420 it's the cruiser 34:51.110 --> 34:56.070 Hurn see if played 35:00.610 --> 35:02.060 call them 35:09.170 --> 35:14.340 the destroyer. 35:14.660 --> 35:23.100 Turn the and if you're down to ship word 35:25.830 --> 35:26.820 in on 35:31.320 --> 35:33.970 type as teams 35:40.390 --> 35:41.800 turn as 35:44.340 --> 35:48.340 and otherwise we're going to return empty. 35:49.890 --> 35:51.120 So it's not there. 35:51.160 --> 35:54.240 Essentially. 35:54.410 --> 36:00.650 So this will take care of drawing on our ships once we place them we have placed them yet. 36:00.920 --> 36:05.370 So it was set up boards. 36:05.360 --> 36:11.590 It's not done yet but we will do that in the next lecture. 36:11.630 --> 36:15.890 But there's one more function we need to take care of and that is 36:18.860 --> 36:22.770 I guess get gets representation. 36:24.650 --> 36:31.890 Gas station at is where 36:34.640 --> 36:39.650 you home. 36:40.100 --> 36:41.370 Laird Yes. 36:41.460 --> 36:48.250 Ord row and column this will be a lot easier on us. 36:48.310 --> 36:48.770 It's 36:51.420 --> 36:56.520 then all return again that star. 36:57.200 --> 36:58.640 Otherwise if 37:01.380 --> 37:05.480 the player gets bored. 37:05.600 --> 37:06.350 Ro 37:09.180 --> 37:11.490 Cohen is a miss 37:14.760 --> 37:26.370 and will return a zero I guess or no lower case as we haven't guessed there is space. 37:28.880 --> 37:32.950 No it's G.T. missed 37:40.530 --> 37:42.140 missed OK. 37:44.280 --> 37:51.750 So that will do it for the drawing functions. 37:52.140 --> 37:54.440 But we still have to actually call the 37:57.640 --> 38:04.980 representations of this one and get this ship or ship repens representation ship 38:07.870 --> 38:41.050 teach in where the row and the call them they and some here get gas station where row and the call. 38:41.130 --> 38:46.040 So if I run this again nothing will change. 38:46.830 --> 38:47.950 Cuz 38:50.330 --> 38:52.880 there's no actual ships on the board yet. 38:53.000 --> 38:59.100 So in the next lecture we're actually going to place the ships on the board and actually get it to draw. 38:59.430 --> 39:00.530 Ok so you then.
