WEBVTT 00:00.080 --> 00:00.530 Hello guys. 00:00.530 --> 00:01.550 Welcome to the video. 00:01.550 --> 00:05.360 In this one we're going to set up background music for the game. 00:05.750 --> 00:07.190 I'm going to be not that difficult. 00:07.190 --> 00:10.070 We just need to get background music itself. 00:10.070 --> 00:12.620 Let's make a folder for sound effects. 00:14.880 --> 00:16.380 Can I call it a suffix? 00:16.410 --> 00:22.110 Can I take these drag them into folder and we're going to need to open this link. 00:22.110 --> 00:27.450 So this the music I'm going to use again I'm going to show you how to use different music if you like 00:27.450 --> 00:31.710 to uh, but as of now I'm just going to use this one because I need some example. 00:31.710 --> 00:33.210 And this music is great. 00:33.420 --> 00:35.520 Uh, you can just click Open in unity. 00:35.520 --> 00:38.340 It will open in your unity for some reason. 00:38.340 --> 00:43.680 Today the asset store is very laggy for me and I cannot open the link. 00:43.680 --> 00:47.040 Oh I can okay, so I did open the link and now I'm going to click. 00:47.940 --> 00:49.020 Uh, download. 00:51.410 --> 00:55.340 Also, I'm not going to use all ten tracks, I'm just going to use two tracks. 00:55.340 --> 00:58.430 So maybe three because I want to show you how to play random music. 00:58.430 --> 01:04.670 And when I'm transferring the project in the end of the section, I'm going to remove this sound from 01:04.670 --> 01:05.630 the project. 01:05.780 --> 01:12.620 And because I want project to be not very big in size, like if I put lots of music there, it's going 01:12.620 --> 01:15.860 to get the size is going to be bigger than I want it to be. 01:15.860 --> 01:19.400 So yeah, I want you to have easy way of downloading the project. 01:19.400 --> 01:21.680 That's why I'm not going to keep sounds in there. 01:21.680 --> 01:26.030 I mean, for the music, you'll have to download them yourself, but it's not that difficult. 01:26.030 --> 01:29.900 As you can see, I'm just doing it right now while I'm talking to you. 01:29.900 --> 01:30.830 What a magic. 01:31.800 --> 01:33.390 Now it did download itself. 01:33.390 --> 01:35.370 So I'm going to try to import. 01:36.640 --> 01:41.680 And as I said, I'm not going to use all of them because I don't want to make it heavy. 01:41.680 --> 01:44.650 So I'm going to just maybe take two. 01:45.840 --> 01:46.140 Okay. 01:46.140 --> 01:46.650 Nice. 01:46.650 --> 01:48.750 Now let me click import. 01:53.310 --> 01:54.840 And let's go back. 01:54.840 --> 01:56.310 Let's go to assets. 01:56.310 --> 02:01.170 Let's change this to background music. 02:03.500 --> 02:07.910 And we're going to take this background music and drag it to audio like that. 02:08.300 --> 02:09.170 Very nice. 02:09.200 --> 02:11.900 Now let's go to the main menu. 02:12.260 --> 02:14.600 We're going to set up things here. 02:14.630 --> 02:17.090 I'm going to go to audio background music. 02:17.120 --> 02:19.520 Going to take these two drag them here. 02:19.550 --> 02:22.850 We're going to uncheck play on awake same as we did before. 02:22.910 --> 02:24.920 And then we're going to give them parent. 02:26.110 --> 02:28.420 Background music. 02:29.170 --> 02:31.930 And we're going to make it as a child of audio manager. 02:31.960 --> 02:32.920 Very nice. 02:32.950 --> 02:34.630 Now let's go to audio manager. 02:34.930 --> 02:39.430 Somewhere here we're going to make serialized field private. 02:40.090 --> 02:44.500 Uh, audio source array BGM. 02:44.980 --> 02:47.740 And then we're going to need methods for this. 02:48.070 --> 02:51.040 And then we need a method that would play background music. 02:51.040 --> 02:56.770 So I'm going to do public void play BGM int BGM to play. 02:56.950 --> 03:03.940 And before we play the music we supposed to stop any music that is playing now or played before. 03:03.940 --> 03:13.030 So I'm going to do uh for loop for the BGM Linux, not sound effects, but BGM links, BGM links and 03:13.030 --> 03:17.410 then over here we need to do BGM with the I dot stop. 03:18.140 --> 03:20.030 So this will stop all of the music. 03:20.030 --> 03:23.990 And after that we can do BGM with the BGM to play. 03:28.640 --> 03:30.920 And let's fix it over here. 03:30.920 --> 03:34.310 So this will play the music if you just call the method. 03:34.310 --> 03:40.250 And now my goal is to play the music all the time while you're playing the game. 03:40.820 --> 03:43.010 And also I want to play random music. 03:43.010 --> 03:44.690 I don't want to play just some music. 03:44.690 --> 03:47.660 So what I'm going to do here is something simple. 03:48.820 --> 03:55.510 We're going to go ahead and make a private int, current BGM and maybe index. 03:57.530 --> 03:59.150 Let's do just BGM index. 03:59.180 --> 04:00.440 BGM index. 04:01.410 --> 04:02.010 Okay. 04:02.010 --> 04:02.700 Good. 04:03.270 --> 04:05.040 Then we're going to make. 04:06.410 --> 04:08.660 A method that would play random BGM. 04:08.660 --> 04:18.050 So I'm going to do public void play random BGM in which we're going to take a BGM index and make it 04:18.050 --> 04:19.790 equal to random range. 04:20.750 --> 04:27.170 Between zero and BGM length, so it will choose one of the elements that is in the array. 04:27.350 --> 04:31.310 And then we're going to do play BGM with a BGM index. 04:32.810 --> 04:33.380 Perfect. 04:33.380 --> 04:38.000 And when music plays and then stops, nothing is going to happen. 04:38.000 --> 04:41.300 Music will just stop playing and BGM index will not be changed. 04:41.300 --> 04:47.390 And thanks to that, we can check if music is playing right now and if no, we can just restart the 04:47.390 --> 04:48.110 music. 04:48.350 --> 04:51.080 So I'm going to make a method public void. 04:51.080 --> 04:54.290 Play music if needed. 04:54.320 --> 04:55.040 All right. 04:55.040 --> 05:02.960 And over here we're going to do if BGM with a BGM index is playing equals to false means we do not play 05:02.960 --> 05:07.460 any music, then we're going to do play random BGM just like that. 05:07.850 --> 05:14.030 And then I want to call this method every now and then, maybe every second or every two seconds. 05:14.030 --> 05:18.860 So we can just check if music is playing and if not we're going to play it again. 05:19.640 --> 05:20.150 Um. 05:21.760 --> 05:24.700 Let's go ahead and do invoke repeating. 05:27.770 --> 05:31.700 Name of play music if needed. 05:32.300 --> 05:39.410 And then we're going to give it, uh, zero delay and repeat rate can be as often as you like. 05:39.410 --> 05:41.480 I suppose that music can stop. 05:41.480 --> 05:44.060 Then it can wait for a couple of seconds and then play again. 05:44.060 --> 05:51.920 So I'm going to do check every two seconds and something else here, just in case. 05:51.920 --> 05:58.040 When we play the music let's do BGM index is equals to BGM to play. 05:58.100 --> 06:02.870 So we do not, you know, interrupt the music with this check over here. 06:02.870 --> 06:07.700 Because this music I mean this check checks BGM index that we have at the moment. 06:07.700 --> 06:09.980 And this will allow us to update the value. 06:09.980 --> 06:12.830 So this one will never be met. 06:12.830 --> 06:16.580 Otherwise you can just interrupt the music you play a certain point. 06:16.580 --> 06:23.000 Like if you want to play a boss fight in music, you can just call play BGM and choose boss fight music. 06:24.210 --> 06:27.570 But then if you do not update this value, then it will be interrupted. 06:28.020 --> 06:29.970 Okay, let's save this all. 06:29.970 --> 06:31.650 Let's go back to unity. 06:32.070 --> 06:37.290 I'm going to just assign this to VMs over here. 06:38.350 --> 06:43.420 And I'm going to go to play mode, and I'm sure I'm going to hear the music. 06:43.420 --> 06:46.960 I cannot check if it starts a new song until I see it. 06:46.960 --> 06:50.950 So I'm sorry, let's make it a serialized field. 06:50.950 --> 06:52.750 And again, I will not. 06:52.750 --> 06:54.100 Oh, what is happening? 06:54.280 --> 06:57.640 Yeah, I will not check this on the video because that would take too long. 06:57.640 --> 07:02.620 But I'll stop recording and then I'll see if New Song began to play. 07:02.620 --> 07:04.090 Okay, that's what I'm going to do. 07:04.690 --> 07:06.040 Um, yeah. 07:06.400 --> 07:10.960 Because otherwise you would have to look how I'm listening to the song until the end. 07:10.960 --> 07:11.860 Not cool. 07:11.980 --> 07:13.060 Let's go. 07:15.500 --> 07:18.830 Oh my God, I'm so sorry I jumped. 07:19.400 --> 07:20.420 So scary. 07:20.450 --> 07:21.890 Let me make volume. 07:23.330 --> 07:24.080 Point one. 07:27.100 --> 07:27.640 Anyway. 07:27.640 --> 07:28.510 It's working. 07:28.600 --> 07:29.080 Yeah. 07:29.080 --> 07:30.130 It began different song. 07:30.130 --> 07:31.510 So random is working. 07:31.510 --> 07:32.470 It's fine. 07:32.620 --> 07:36.250 And let me try to make it lower. 07:36.460 --> 07:37.510 Like even lower. 07:39.430 --> 07:40.780 I can hear it's playing. 07:40.780 --> 07:45.370 I'm going to go to continue and I can hear the music. 07:45.400 --> 07:48.370 Very cool, I like it. 07:49.540 --> 07:52.300 Um, yeah. 07:52.870 --> 07:55.030 Other than that, I guess there is nothing to do. 07:55.030 --> 08:00.160 I'm going to check if music is playing again when it's off, like off the screen. 08:00.160 --> 08:03.730 And other than that, if something is wrong, I'm going to let you know. 08:03.730 --> 08:05.080 Now let's go to the next video. 08:05.080 --> 08:07.390 We're going to set up the volume settings.
