WEBVTT 00:02.490 --> 00:04.500 An that's it. 00:04.590 --> 00:07.110 So you run this 00:10.990 --> 00:12.370 well you can't run it quite yet. 00:12.370 --> 00:14.490 So let's implement. 00:14.500 --> 00:15.760 Want to play again. 00:19.500 --> 00:20.850 And then run it. 00:20.850 --> 00:30.160 See so let's just add it after the game. 00:30.490 --> 00:38.900 All that. 00:39.370 --> 00:39.740 Here 00:44.470 --> 00:46.840 in for one to play. 00:46.900 --> 00:47.570 Ken 00:52.680 --> 00:55.020 are you going to use our 00:58.650 --> 01:00.280 two functions. 01:00.290 --> 01:05.020 You have these two in fact use this function. 01:05.220 --> 01:13.880 So let me copy this I'll add it to the declarations yet. 01:14.400 --> 01:16.160 Two declarations 01:26.550 --> 01:27.220 this 01:31.740 --> 01:39.110 these two get character functions and you're going to use that in want to play again to make it easier. 01:39.130 --> 01:49.430 So remember how it works is we're going to have a Auray it's char. 01:49.470 --> 02:02.940 So here's the one for the valid inputs and the only valid inputs right to have are yes and no y in this 02:05.120 --> 02:15.940 and how we're going to say is your response Z to get character and we're calling the function. 02:15.950 --> 02:21.290 And then we call it with the prompts would you. 02:23.940 --> 02:26.630 Again and yes or no. 02:29.700 --> 02:36.500 And this is the Arab Spring and we actually are defined it above the error string. 02:37.520 --> 02:45.760 And valid inputs and the length of how many got there. 02:46.410 --> 02:53.160 And then all we have to do is a return response equal to it's 02:57.630 --> 03:01.860 so let's actually run this and see what we have so far. 03:03.030 --> 03:15.480 So hello and see it through the gallows and it drew five dashes right and now it's asking see if you 03:15.480 --> 03:16.690 want to play again. 03:17.720 --> 03:19.980 So no. 03:20.390 --> 03:24.950 So now let's actually do the rest of play again. 03:26.090 --> 03:29.180 So we know our draw board works. 03:29.180 --> 03:34.890 That's good really help and it's just implement the rest of the game. 03:34.970 --> 03:53.900 So while not is over in to the number of guesses laughs and the hidden phrase 03:56.590 --> 03:57.110 dher 03:59.730 --> 04:10.820 raise and the length and I'm going to pass the secret phrase like well just to not have to call Sterlite 04:10.830 --> 04:14.740 again mostly and just kind of notice that. 04:15.230 --> 04:16.390 Rob Ford. 04:16.520 --> 04:22.170 There should be no pointer. 04:22.280 --> 04:23.460 This guy doesn't own it. 04:25.770 --> 04:31.490 So that's copying pasting things or is bad usually. 04:31.910 --> 04:37.880 So try not try to avoid it if you can cause bad things will happen and so should be no pointer for hidden 04:37.880 --> 04:41.780 phrase in draw the draw board. 04:44.650 --> 04:45.430 So 04:49.040 --> 04:54.430 let's just skip implementing this for now and just get the rest of the stuff we'll get the guest guess 04:54.560 --> 04:57.280 is just a character right. 04:57.530 --> 05:02.560 So get the gas and to do that we will 05:05.190 --> 05:08.920 have this gas function improvement 05:11.280 --> 05:21.910 and the other one is the update board I'm just following our top down design right now I'm not implementing 05:21.910 --> 05:28.240 anything and passing the gas and the hidden phrase 05:32.850 --> 05:39.170 and the secret phrase. 05:39.420 --> 05:43.590 And again I'll pass in the secret. 05:43.780 --> 05:48.120 It's like. 05:48.540 --> 05:50.960 And then I will draw the board. 05:54.530 --> 05:56.520 That's Amber. 05:56.670 --> 06:02.060 Yes is left and the 06:06.570 --> 06:07.230 phrase 06:12.400 --> 06:21.460 so soft implement get gas update board and it came over and let's just round out play games. 06:21.470 --> 06:23.880 Would have to come to it again this way. 06:23.910 --> 06:33.530 So it's an say the secret phrase here and a number of guesses. 06:35.090 --> 06:43.680 What and the last thing we need to do is since we own that pointer we have to delete it. 06:43.830 --> 06:49.220 So pointer hidden goodies like this. 06:51.360 --> 06:54.170 So it's only good for the duration of the game. 06:54.190 --> 06:55.680 You know other words. 07:08.770 --> 07:12.450 So now let's finish all this stuff. 07:15.020 --> 07:18.370 Seltsam might get guess. 07:18.400 --> 07:22.010 So it's going to turn a character. 07:22.600 --> 07:27.960 Will actually be using get character for our get gas function. 07:28.150 --> 07:30.070 Character. 07:30.140 --> 07:30.700 Yes. 07:30.780 --> 07:32.790 Returns nothing. 07:34.740 --> 07:35.500 Copy that. 07:39.700 --> 07:42.220 And let's 07:45.440 --> 07:49.390 in and really care about ordering too much right here. 07:50.470 --> 07:53.140 And it's going to do 07:56.820 --> 07:57.840 is 08:01.620 --> 08:14.270 very simple return get character using that function again these input guests and it takes in the input 08:14.310 --> 08:22.840 air strings but are straight. 08:23.210 --> 08:23.720 That's it. 08:27.410 --> 08:31.950 And let's do the date for now. 08:33.120 --> 08:38.310 Even more interesting function. 08:38.350 --> 08:41.650 So it's not going to return anything. 08:41.650 --> 08:52.990 So the guest is a character the changes changes no pointer rank because update or doesn't own it and 08:53.690 --> 08:56.600 you can change it so it should just be a char a star. 08:56.650 --> 09:07.110 This and the secret phrase is a character attracted me to a concert. 09:07.250 --> 09:09.030 This never changes either. 09:10.050 --> 09:10.640 That 09:13.400 --> 09:25.800 and Lanc and we're actually missing something the number of guests is left and that will be a reference 09:27.370 --> 09:37.990 Amber guesses less as we can update the number of guesses left and it will change our callers version. 09:38.150 --> 09:44.620 And that's why it's that reference so it's copy this 09:48.100 --> 09:54.780 here and still pass in the number of guesses left. 10:00.770 --> 10:03.880 And so put it right here. 10:06.910 --> 10:07.750 OK. 10:09.260 --> 10:13.730 So date the board. 10:13.820 --> 10:25.530 So how did we do this so we're basically just looking to see if we found a letter or we found the guess 10:25.590 --> 10:28.440 in the secret phrase. 10:28.440 --> 10:28.750 Right. 10:28.770 --> 10:36.530 And if we did we reveal the that letter and each position of the hidden phrase. 10:36.660 --> 10:45.930 What we didn't do here is to see if because since like an uppercase H is not the same as a lowercase 10:45.990 --> 10:49.530 H we have to ignore case here. 10:49.620 --> 10:56.560 So we're going to ignore the case of the secret phrase. 10:56.880 --> 11:06.480 So we're actually going to make this to lower because our guess is also in lowercase so that and in 11:06.480 --> 11:13.470 fact what we should do here instead is actually say secret phrase. 11:13.620 --> 11:16.500 Because what if they typed in. 11:17.730 --> 11:24.740 Hello right or and high like this. 11:24.800 --> 11:26.900 OK that's a secret phrase. 11:27.040 --> 11:35.330 So if they typed in h it should match h this H which is uppercase and this H. 11:35.590 --> 11:43.850 And if we said it to the guess it would this would be lowercase which is not correct. 11:44.140 --> 11:49.300 Like this what we want to do is just keep it the same as the secret phrase. 11:49.330 --> 12:03.940 So it's you that so here we're going to say have we found one or no 12:07.120 --> 12:15.950 and we're going to use that for for decrementing the number of guesses later. 12:16.200 --> 12:34.970 So for he goes to zero eyes less than the length of or secret phrase like sorry secret Rhee's Lanc 12:37.820 --> 12:40.150 plus. 12:40.370 --> 12:54.170 And if to lower your secret phrase I call to you the guess. 12:54.220 --> 13:02.790 So if the lower case version of the secret phrase is current letter is the same as the guess then we 13:02.790 --> 13:17.580 should say hidden or no pointer in phrase eyes equal to the secret phrase. 13:17.820 --> 13:21.150 And that's not to lower of the secret phrase of I. 13:21.150 --> 13:27.940 Because again we want to preserve the case when it's output but not when we check. 13:29.960 --> 13:33.240 And then we have found it true. 13:34.780 --> 13:43.050 And here if we we didn't find it right then we should 13:45.890 --> 13:48.410 subtract one from the number of guesses left 13:57.640 --> 14:02.170 that is update board so we're almost done. 14:02.360 --> 14:11.820 We only have two functions left so we should implement is 14:15.140 --> 14:16.420 to do that now. 14:22.360 --> 14:24.910 So it's over. 14:25.020 --> 14:28.000 Who'll right turns. 14:28.010 --> 14:31.930 Boolean it's over or not the number of guesses left. 14:31.930 --> 14:37.520 So this would just be a copy because you don't need to know or it doesn't need to change it at all. 14:37.540 --> 14:51.510 So this is the conc char star and no pointer rank doesn't own it. 14:55.100 --> 14:56.290 Copy this. 14:58.470 --> 15:03.960 It Right after the oared. 15:04.030 --> 15:05.770 So how do you know if it's over. 15:05.770 --> 15:09.340 So we go through. 15:09.450 --> 15:15.770 So we go through each of the characters in the hidden phrase to see if it's a dash. 15:16.110 --> 15:24.910 If we do have a dash and it can't this game can't be over or if the number of guesses is 0 then it's 15:24.910 --> 15:25.400 over. 15:25.440 --> 15:26.280 Right. 15:26.590 --> 15:27.310 So 15:30.730 --> 15:36.270 three here so see bhool has Dasch. 15:36.510 --> 15:40.360 All else for. 15:40.570 --> 15:52.540 So your source then the secret phrase like boss. 15:52.800 --> 16:02.960 If the new pointer didn't phrase is equal to a dash 16:09.190 --> 16:10.650 then we do have ash 16:17.360 --> 16:25.370 and we want to just break out of the loop because now we know the game or at least has a dash so at 16:25.370 --> 16:32.920 least that portion of the game is not over a number of guesses left. 16:32.940 --> 16:46.110 It's 0 or doesn't have a dash and you know is over. 16:46.200 --> 16:51.900 And finally we have the display results 16:53.990 --> 17:01.250 so it's implement that fairly simple. 17:01.440 --> 17:02.940 So it's copy 17:12.660 --> 17:14.260 it won't return anything 17:16.970 --> 17:24.430 and it'll take a constant Shore star. 17:24.660 --> 17:24.920 Number 17:32.960 --> 17:41.740 it's meant that it's so should be pretty much the same as the number guesser version so if the number 17:42.780 --> 17:49.100 guesses length is greater than zero then you got it right. 17:49.190 --> 17:51.920 C-O got it. 17:53.740 --> 17:56.040 The word is 18:02.540 --> 18:03.600 free. 18:03.660 --> 18:04.590 Yes. 18:07.590 --> 18:08.190 Tres 18:10.790 --> 18:11.390 else 18:18.040 --> 18:19.100 didn't you get it. 18:22.670 --> 18:22.970 Free. 18:23.220 --> 18:23.780 It's 18:29.520 --> 18:29.930 so 18:37.520 --> 18:38.200 phrase 18:44.480 --> 18:47.490 so hopefully that makes sense as well. 18:49.280 --> 18:59.220 So I we're basically done written like 500 lines of code Well probably not because of all this 19:01.970 --> 19:12.360 is comments here but let's read this hidden it's so me that will be there. 19:12.380 --> 19:19.880 So say hello everyone. 19:20.230 --> 19:23.630 So we have a nice Remy. 19:23.650 --> 19:23.930 Hello. 19:23.930 --> 19:25.220 Hi. 19:29.230 --> 19:39.890 Each local lowercase So center so nicely we have the dashes of each thing. 19:39.890 --> 19:42.560 So say H. 19:43.130 --> 19:52.610 And notice that it's said or it output a capital H and a lowercase h properly even though we just entered 19:52.610 --> 19:53.860 a lower case H. 19:53.920 --> 19:54.930 That's working. 19:58.890 --> 20:00.880 How right. 20:00.970 --> 20:01.530 Let's guess. 20:01.560 --> 20:03.700 Let's get it wrong. 20:03.820 --> 20:07.700 W o that head. 20:08.410 --> 20:30.320 Say a Q No and say F is the arm say G the other arm and say k 20:33.600 --> 20:34.620 are almost dead. 20:34.650 --> 20:40.660 So let's actually lose this one and that's a B. 20:41.000 --> 20:43.240 So you can get at the phrases. 20:43.370 --> 20:43.760 Hello. 20:43.760 --> 20:44.810 Hi everyone. 20:44.910 --> 20:45.490 OK. 20:45.740 --> 20:47.920 Would you like to play again. 20:48.070 --> 20:50.000 Let's just rerun this. 20:50.180 --> 21:00.530 So we have a clear console and I'll show you an and this time this is it. 21:00.720 --> 21:07.950 Each see all the R Y 21:11.380 --> 21:11.860 II 21:16.490 --> 21:20.010 inch and a. 21:20.110 --> 21:22.240 Got it. 21:23.030 --> 21:27.900 So that's the major implementation of hangman. 21:28.260 --> 21:32.500 We're following along and I went a little bit quickly. 21:33.650 --> 21:43.550 In the next lecture though I want to go over some odds and ends with this game and see if we can do 21:43.550 --> 21:46.040 a little bit more to it and change a little bit more. 21:46.040 --> 21:49.480 So I will see you in the next lecture.
