WEBVTT 00:00.520 --> 00:08.070 Know that we have most of the game working I want to start focusing on the game States. 00:08.170 --> 00:13.650 So the intro and game and game over. 00:13.750 --> 00:25.810 So if we are in the update game function and if we actually finish killing all the aliens so the number 00:25.810 --> 00:32.930 of humans we have left is zero then we should kind of restart the game. 00:32.930 --> 00:37.760 So when I say game level plus 00:40.640 --> 00:46.040 and are going to make sure that the games level can't exceed 00:49.210 --> 00:51.210 10 in this case. 00:51.490 --> 00:54.310 So the level 00:59.380 --> 01:08.430 and to do that we're just going to say modulus 10 but we're going to add one because it's one game of 01:08.560 --> 01:10.820 really one to 11. 01:10.960 --> 01:12.920 So. 01:13.810 --> 01:20.170 So then we'll put the game in the wait state. 01:22.510 --> 01:25.390 Or a certain amount of time 01:29.670 --> 01:40.740 and we'll make a new function call the reset game you know take game the player aliens and the shield. 01:40.760 --> 01:43.970 It's because you have to reset all of those things. 01:50.630 --> 01:54.270 And we should be making some constants these 01:56.740 --> 02:07.880 say we each time and also what levels 10 02:18.950 --> 02:20.480 a week time 02:27.290 --> 02:30.760 is OK. 02:30.800 --> 02:36.200 So we're going to declare Game of 02:42.520 --> 02:44.380 Character nothing. 02:49.730 --> 02:54.140 And take the game by reference whereby reference 02:59.590 --> 03:01.890 and warm 03:06.920 --> 03:08.380 shields 03:11.410 --> 03:15.580 shields. 03:15.770 --> 03:24.080 It's meant this shouldn't be too hard. 03:24.280 --> 03:25.090 So 03:31.360 --> 03:36.330 basically going to have more have reset player. 03:36.440 --> 03:36.940 Remember 03:42.880 --> 03:50.560 they are going to need some kind of resetting of the shields because what if some of them got hit during 03:50.740 --> 04:04.700 game and we need to kind of re re-establish the shields so of that and going to re-initialize 04:06.710 --> 04:08.090 the alien. 04:08.190 --> 04:09.620 It's well 04:14.530 --> 04:15.330 niche. 04:15.390 --> 04:16.780 You know this is called 04:19.890 --> 04:20.290 K. 04:20.300 --> 04:30.520 So really we just need to omit this one. 04:30.920 --> 04:32.020 Copy this. 04:37.920 --> 04:39.230 Clear of 04:46.980 --> 04:49.960 don't think each change game at all. 04:56.240 --> 04:56.900 You 05:02.350 --> 05:03.130 you it's 05:06.030 --> 05:08.230 so here. 05:10.690 --> 05:13.610 It's implemented. 05:14.410 --> 05:19.990 But we actually have a bunch of the stuff we need for research fields. 05:20.170 --> 05:32.440 So let's actually take some of the things that we had in the initialize initialize of shields that was 05:35.630 --> 05:50.660 so here and actually just take them take it and you will sort of follow the same pattern. 05:50.730 --> 05:58.030 So essentially want is to take this stuff. 05:58.030 --> 06:00.340 So actually just going to copy this for now. 06:03.080 --> 06:11.850 And we won't need it since we are going to use to take away all this stuff. 06:11.930 --> 06:17.960 We're not going to need it we're going gonna set all the positions and all that stuff elsewhere. 06:18.320 --> 06:22.830 And we're also going to copy it elsewhere. 06:24.080 --> 06:35.640 So initially Shields is really just making the new call or clicking clicking the memory that we need. 06:36.110 --> 06:43.740 So here in reset shields you don't need to do this all 06:49.230 --> 06:53.750 and really that's itch. 06:54.000 --> 06:56.770 We're just going to kind of do it again. 06:56.850 --> 07:04.120 Essentially So inside of the shields now on 07:11.030 --> 07:14.620 down here to say reset to shew it's 07:24.270 --> 07:31.450 like so and so kind of make it all and then it'll reset it. 07:31.500 --> 07:35.550 So now that we have that working 07:38.400 --> 07:43.480 I want to go back to a 07:51.710 --> 07:53.300 game maze 07:59.160 --> 08:09.260 so now that we have this we just did let's actually since since we're beginner level let's actually 08:09.560 --> 08:13.490 set the level in the initialize game. 08:16.020 --> 08:24.290 So we don't we don't need this here we're actually going to move this is going to move it right below 08:24.340 --> 08:33.920 also the start of the game the level is 1 K so we're going to move that from there. 08:34.650 --> 08:43.020 And now we're going to do is in the update aliance 08:50.120 --> 08:50.600 is 09:00.020 --> 09:01.890 here. 09:02.710 --> 09:15.150 When we redid this like line minus minus Well if you if the line is at 0 09:22.330 --> 09:25.050 then we will. 09:25.360 --> 09:28.360 Well the game's over right there at the bottom. 09:28.360 --> 09:32.140 So are you going to say current state is. 09:32.170 --> 09:32.560 Yes. 09:32.560 --> 09:37.320 Game over in poker turn false. 09:37.320 --> 09:43.370 And since this is being passed by constant references needs to be passed by reference. 09:43.450 --> 09:47.580 Now the above here is say 09:50.520 --> 09:52.520 that each. 09:52.660 --> 09:55.000 So now in Drog game 09:58.930 --> 10:00.520 it's not here. 10:03.340 --> 10:11.470 We also need some other drawings right because we need to be able to draw 10:14.750 --> 10:20.190 the game over screen and the intro screen. 10:20.210 --> 10:23.960 So I say yes over 10:28.140 --> 10:29.260 hurts it's 10:31.900 --> 10:39.610 catch on to make new functions called draw over screen 10:42.080 --> 10:43.350 as game 10:46.230 --> 10:48.810 repressing the game for the screen. 10:48.900 --> 10:50.470 Right. 10:51.270 --> 10:58.800 And also for if game current state is in intro 11:01.860 --> 11:05.280 then we'll draw our interest in 11:09.280 --> 11:13.220 going to pass it game as well. 11:13.570 --> 11:18.820 So now that we have that science we back up here. 11:23.520 --> 11:31.570 And let's declare the draw over screen 11:34.450 --> 11:35.880 and change the game at all 11:38.630 --> 11:42.700 we need to draw. 11:44.380 --> 11:52.060 And these will be pretty simple all we're going to say is game over in the gamer screen and kind of 11:52.150 --> 11:56.990 welcome to text readers and your screen. 11:57.180 --> 11:59.070 So what's copy's 12:04.060 --> 12:05.020 here. 12:09.930 --> 12:16.540 You will draw the game or at the intro screen screen. 12:16.640 --> 12:28.950 So start with the rescreen and real say is Konst char and uber string. 12:29.370 --> 12:30.820 Well actually we could. 12:31.050 --> 12:36.100 Sure using string regular string. 12:36.100 --> 12:40.330 We will be Salt's include string this 12:44.970 --> 12:49.780 so year or so since string 12:52.650 --> 13:01.890 over string this in say more and also say 13:04.490 --> 13:06.100 space string 13:10.210 --> 13:17.730 say press space bar to continue. 13:17.960 --> 13:22.000 And basically when you press the spacebar go back to. 13:22.070 --> 13:23.170 Interesting. 13:23.440 --> 13:28.550 OK so now we're going to 13:31.360 --> 13:32.590 format it properly. 13:32.610 --> 13:36.330 So to say 13:44.550 --> 13:52.790 why pause will be the dot each new size 13:55.950 --> 13:57.690 height over 2. 13:57.710 --> 14:06.790 For now so be kind of in the middle of the screen and we'll say 14:15.970 --> 14:29.450 we'll say the counts in each game over exposition will be the number one the size 14:32.740 --> 14:40.680 over to minus the length of the game over screen or over a string sorry 14:43.870 --> 14:45.370 link to 14:53.440 --> 14:59.660 that also for the press. 14:59.960 --> 15:25.370 Base position. 15:25.450 --> 15:30.120 So now that we have these two need to drives. 15:30.310 --> 15:37.350 So you don't have any kind of drawstring function. 15:37.650 --> 15:38.970 We could 15:41.260 --> 15:44.760 so in our utilities. 15:45.010 --> 15:58.140 Let's make a new function drawstring take it by the exposition in the White position and we'll pass 15:58.140 --> 15:59.490 in a string. 15:59.580 --> 16:03.590 So I need to include spring here. 16:07.440 --> 16:16.220 Passed by conc string reference string. 16:20.700 --> 16:21.570 Copy that. 16:23.370 --> 16:27.740 In the low draw Spryte Cedras drawstring 16:35.120 --> 16:38.460 and will say in the 16:40.820 --> 16:45.000 W Y pause X pause right. 16:45.090 --> 16:58.020 So that's why then X and string dot string. 16:58.120 --> 17:05.330 So now we'll just say draw string 17:07.680 --> 17:09.210 and say 17:11.640 --> 17:27.320 the game over exposition in the wives action in the game over string that way and then we'll say draw 17:27.320 --> 17:30.620 string. 17:31.000 --> 17:50.570 Press this base exposition and it'll just be right below the game over on. 17:50.580 --> 17:58.470 So that will draw the game over screen and let's do it for the intro screen. 18:01.130 --> 18:02.600 So say 18:06.860 --> 18:11.900 string start is great. 18:13.420 --> 18:17.600 And this is just say welcome to Tex 18:20.510 --> 18:21.620 meter's 18:25.970 --> 18:42.960 and now the string called in press piece string. 18:45.040 --> 18:54.250 And just like four we need to have like the y position image make it. 18:54.430 --> 18:56.200 Now in middle 19:07.670 --> 19:12.180 just for you just want to get the middle of the screen. 19:41.490 --> 19:42.500 Next pause 20:06.480 --> 20:11.100 exactly the same as above and see drawstring 20:14.760 --> 20:23.740 start ch starting position y position Sturtze string 20:27.480 --> 20:35.970 Smillie draw string. 20:37.040 --> 20:46.470 Why is this one is Speace string that. 20:46.870 --> 20:53.460 Now we have our interest screens and you can go as crazy as you want with it but it is going to do something 20:53.460 --> 20:54.080 simple. 20:54.090 --> 21:01.480 Now now that we have these two functions it will draw. 21:01.560 --> 21:07.930 We still need to make it actually. 21:08.080 --> 21:12.200 If you actually do hit spacebar you actually go with the proper thing. 21:12.200 --> 21:15.880 So now in 21:20.350 --> 21:22.810 handle input space 21:26.030 --> 21:28.140 will need some extra 21:30.990 --> 21:35.060 extra things in here to go to the right spot. 21:35.070 --> 21:40.710 Essentially so are Assi else if 21:43.180 --> 21:44.610 game. 21:45.160 --> 21:54.740 Current state is Jesus came over. 21:55.130 --> 21:59.870 If it's game over then we'll say game. 22:00.070 --> 22:10.890 Each current state intro so can't go back to the intro once the game's over and we will 22:13.210 --> 22:14.080 essentially 22:16.260 --> 22:21.040 reset. 22:21.270 --> 22:22.400 Said game 22:37.900 --> 22:39.580 to have. 22:39.790 --> 22:41.940 So we don't really have too much. 22:41.990 --> 22:47.610 So we need the handle input on need a few other things right. 22:47.690 --> 22:49.720 So need the aliens. 22:56.750 --> 22:58.790 Need shields. 23:02.270 --> 23:03.490 Or it's 23:07.390 --> 23:09.390 modify and put 23:17.690 --> 23:20.590 you in put here. 23:24.110 --> 23:29.200 And when to has everything. 23:29.300 --> 23:32.540 She's well and she U-Mass 23:35.190 --> 23:36.340 she. 23:39.010 --> 23:41.020 Or Shields is 23:52.650 --> 23:59.320 in past the player in New Orleans she you. 23:59.330 --> 24:01.530 It's number. 24:01.770 --> 24:02.220 It's 24:09.640 --> 24:15.670 so that should fix fix all that. 24:17.490 --> 24:19.320 So now in 24:22.570 --> 24:24.080 are we also need a yes. 24:24.100 --> 24:29.020 The intro. 24:29.250 --> 24:35.790 So if we're in the interstate we should just press enter as well or not enter that space and then go 24:35.810 --> 24:40.980 to the play games state. 24:41.120 --> 24:53.790 Also in the actually before we do that in the IT game starts in issue as well. 24:54.030 --> 24:55.120 It's run this 25:00.550 --> 25:02.360 so you're in it. 25:02.380 --> 25:14.370 And we actually start in the intro which is very and press space bar in which you can see that we're 25:14.370 --> 25:15.630 playing the game 25:22.430 --> 25:25.940 so that's great. 25:26.000 --> 25:28.520 I want to die three times and see 25:32.610 --> 25:34.030 see what happens. 25:34.050 --> 25:35.340 Subduct wants 25:43.160 --> 25:46.180 heard dodging into things twice. 25:46.210 --> 25:46.780 As good 26:09.050 --> 26:10.480 in Rio. 26:10.780 --> 26:12.460 So I died three times. 26:12.760 --> 26:13.350 So there you go. 26:13.360 --> 26:14.460 Game over. 26:14.470 --> 26:15.360 Good. 26:15.940 --> 26:17.050 So that's working. 26:17.050 --> 26:27.110 So if I press baseball again I'd go back to Texan maters and if I go back into it it resets correctly. 26:27.260 --> 26:30.770 I thought it would and we're playing again. 26:30.890 --> 26:32.660 So that's that's good. 26:35.240 --> 26:35.930 OK. 26:36.000 --> 26:39.080 So seems to be working. 26:39.280 --> 26:44.030 You think thing we need to check in we're going to make our 26:47.390 --> 26:49.600 aliens go really fast again. 26:49.610 --> 27:01.650 So the thing is check is if we go really fast so it should also be a game over. 27:04.550 --> 27:13.550 So if they drop down to zero in the line then shoot over. 27:13.710 --> 27:14.460 Game over. 27:14.500 --> 27:15.410 Good. 27:17.360 --> 27:19.640 So everything's working pretty well. 27:19.640 --> 27:22.830 I think it's good. 27:22.840 --> 27:31.150 So that was kind of the sort of brief overview of the game States. 27:31.420 --> 27:35.660 You know sometimes it's hard to follow. 27:35.920 --> 27:41.570 But really all we did was show you the 27:53.830 --> 27:57.010 so in the update game. 27:57.080 --> 27:58.440 So when we. 27:58.550 --> 28:04.530 So the first thing we did was if we have no means left which I still haven't actually shown is I maybe 28:04.550 --> 28:08.120 we should do that actually before you wrap up. 28:08.450 --> 28:11.590 We go to the next level and then we kind of reset the game. 28:11.590 --> 28:14.380 So everything is working OK. 28:15.980 --> 28:21.200 And then in the trial game we also draw. 28:21.200 --> 28:25.390 Now the game over screen and intro screen. 28:25.880 --> 28:30.720 So it will only draw the player and the alien stuff in play. 28:30.740 --> 28:33.230 Game or the player is dead or waiting. 28:33.260 --> 28:33.600 OK. 28:35.980 --> 28:40.240 And it's changed too much of this 28:43.180 --> 28:48.850 it of course it actually drew the game over screens like this. 28:48.960 --> 28:49.610 Simple. 28:49.680 --> 28:52.370 A new function for draw string. 28:52.990 --> 29:03.450 We reset the shields because they need to be reset every time the game is over and we want to play again. 29:03.850 --> 29:06.840 We also did a reset game. 29:07.060 --> 29:08.650 So what's actually 29:11.380 --> 29:19.740 actually tried to win and see if we can go to the next level. 29:19.800 --> 29:21.890 So I actually try here. 29:33.520 --> 29:36.950 So that my trying is still not good enough. 29:37.490 --> 29:37.800 Well 29:48.390 --> 29:49.310 one more try. 30:12.590 --> 30:13.650 So close 30:23.790 --> 30:25.920 it resets it. 30:25.950 --> 30:30.570 They are actually lower for well. 30:30.640 --> 30:35.070 So everything is working the way we expect. 30:35.090 --> 30:36.210 Just great. 30:36.440 --> 30:37.630 OK. 30:37.630 --> 30:45.290 And there's one last thing and that is we're not showing the players 30:47.870 --> 30:49.920 players like lives and stuff like that. 30:49.980 --> 30:50.450 Right. 30:54.580 --> 31:00.430 So let's let's also show that it's 31:03.100 --> 31:05.670 one drop later. 31:16.220 --> 31:18.780 In drub player will say 31:23.680 --> 31:32.320 say the print w 0 0 score 31:34.830 --> 31:44.350 so Urd's using curses directly for this wise. 31:46.970 --> 31:48.210 Weird. 31:49.730 --> 31:50.950 Score. 31:55.060 --> 32:00.260 Where is k. 32:00.750 --> 32:08.690 And you may be wondering I haven't actually imported or included curses and cirqus. 32:08.730 --> 32:10.470 I actually have. 32:10.560 --> 32:15.240 Because it's part of the curse is Eutelsat h. 32:15.360 --> 32:18.160 So that's why I can actually use it here. 32:18.240 --> 32:27.940 Work so I snatch up my score so I don't actually set the score so see it's a negative. 32:27.940 --> 32:30.940 Something terrible will fix that 32:35.190 --> 32:37.210 in initialize player. 32:37.540 --> 32:44.500 I notice that you never said or score so it. 32:44.630 --> 32:45.730 You're right again 32:48.390 --> 32:56.550 and notice that actually lives went down scores going up. 32:56.790 --> 32:58.620 It kicked them out. 32:59.840 --> 33:04.510 So everything's working which it. 33:04.630 --> 33:14.630 So in the next lecture I want to go over drawing the Alien or the alien UFO that we haven't tried yet. 33:14.680 --> 33:16.600 So see you in the next lecture.
