WEBVTT 00:00.110 --> 00:00.530 Hello guys. 00:00.530 --> 00:01.550 Welcome to the video. 00:01.550 --> 00:04.790 In this one I want to show you how to make another enemy. 00:04.790 --> 00:06.860 This time it's going to be a blue bird. 00:06.860 --> 00:10.160 And probably it's going to be the last enemy we're going to make in this course. 00:10.160 --> 00:16.130 I want to show you this one, just to give you an example on how you could mix the movement from a transform 00:16.130 --> 00:19.850 like a vector to move towards and rigid bodies velocity. 00:19.850 --> 00:24.230 It's a very suitable example to give, because you can see how you can mix those movements when you 00:24.230 --> 00:27.170 need some special behavior from the enemy. 00:27.170 --> 00:28.610 And let's go to. 00:29.850 --> 00:30.510 Asset. 00:30.510 --> 00:31.500 Prefabs. 00:31.500 --> 00:32.670 Enemies. 00:33.580 --> 00:35.080 Uh, sorry. 00:35.080 --> 00:36.190 We need graphics. 00:36.190 --> 00:37.120 Enemies. 00:37.600 --> 00:42.670 Bluebird, make sure you have this with a pixel per unit 16 over here. 00:42.760 --> 00:47.590 And then, uh, maybe I can do prefab unpack completely for the reddish. 00:47.590 --> 00:51.160 Make sure you have it as a prefab, then unpack it. 00:52.250 --> 00:56.330 We don't need gunpoint for this and we don't need this script. 00:56.330 --> 01:00.500 And on sprite renderer, we can just take the flint sprite of the bird. 01:01.130 --> 01:03.740 Okay, let's adjust collider. 01:06.210 --> 01:06.510 Hmm. 01:06.510 --> 01:08.400 Something like this should work. 01:10.570 --> 01:12.730 Yeah, but the damage trigger. 01:12.730 --> 01:14.110 I'm going to move it. 01:16.290 --> 01:17.880 Here like that. 01:18.300 --> 01:19.830 Some reason it's not in the center. 01:19.830 --> 01:23.160 So I'm going to remove offset and do like that okay. 01:24.510 --> 01:25.170 Nice. 01:26.510 --> 01:27.920 Now we need a script on this. 01:27.920 --> 01:29.210 And animator. 01:29.210 --> 01:31.640 Let's go to asset animations. 01:31.640 --> 01:32.600 Enemies. 01:37.890 --> 01:38.700 Enemies. 01:38.730 --> 01:40.290 We're going to make a folder. 01:42.350 --> 01:43.730 Bluebird. 01:44.430 --> 01:45.030 Inside. 01:45.030 --> 01:46.560 We need animator. 01:48.750 --> 01:49.680 Enemy. 01:49.890 --> 01:51.870 Blue bird. 01:51.900 --> 01:52.470 AC. 01:53.160 --> 01:55.980 Let's put it on a bird over here. 01:57.980 --> 01:59.600 And let's create a clip. 01:59.840 --> 02:05.240 It's not many this time, so we're just going to do enemy Blue Bird Fly. 02:05.390 --> 02:07.160 Let's go to graphics. 02:08.030 --> 02:08.990 Enemies. 02:08.990 --> 02:09.740 Bluebird. 02:09.740 --> 02:12.170 We're going to take flying animation. 02:12.170 --> 02:14.120 Sample rate 20. 02:14.600 --> 02:16.910 And we need one more enemy. 02:16.910 --> 02:19.310 Blue bird hit. 02:20.230 --> 02:21.460 We're going to take hit sprite. 02:21.460 --> 02:22.480 Drag them here. 02:22.480 --> 02:24.100 Sample rate 20. 02:25.340 --> 02:31.820 Okay, let's go to animator of this bird and we're going to need one trigger hit. 02:32.420 --> 02:34.460 We're going to transfer to Bluebird hit. 02:34.460 --> 02:38.720 We can do it from anywhere because we have only two animations with the trigger. 02:38.720 --> 02:39.800 Hit exit time. 02:39.800 --> 02:42.920 Uncheck transition duration zero okay. 02:43.400 --> 02:44.810 And this is ready. 02:44.810 --> 02:49.250 Let's go to Asset Scripts enemies and let's make. 02:50.800 --> 02:53.290 Enemy Blue Bird. 02:57.150 --> 03:04.770 Actually for Bluebird, we don't need to do inheritance from any script because none of these things 03:04.770 --> 03:07.620 is going to be used on the bird, I guess. 03:07.620 --> 03:09.780 But there are some things like. 03:11.210 --> 03:15.020 Animator component and colliders and so on. 03:15.020 --> 03:17.360 As since we're doing it like that, I guess. 03:17.360 --> 03:22.310 Yeah, let's let's do inheritance, even though we're not going to use most of the things, it will 03:22.310 --> 03:24.200 be faster and easier this way. 03:24.230 --> 03:26.060 Now let's make a header. 03:26.570 --> 03:29.840 Blue bird details. 03:29.840 --> 03:36.650 And over here I want to have a serialized field private float travel distance. 03:36.650 --> 03:39.200 And let's make it equals to eight by default. 03:39.560 --> 03:42.800 So travel distance is going to define how bird is going to fly. 03:42.800 --> 03:46.370 It will help us to set up movement of the bird in a very easy way. 03:46.460 --> 03:47.570 Here is the bird. 03:47.750 --> 03:53.690 And if we have travel distance of eight it means it's going to move like this is the travel distance 03:53.690 --> 03:56.480 and minus four to the left, plus four to the right. 03:56.480 --> 04:00.680 And it's going to just, uh, have a distance of eight in total. 04:00.680 --> 04:03.200 So that's what I want to have for the movement of the bird. 04:03.470 --> 04:05.540 Now let's make a waypoints. 04:05.540 --> 04:08.810 I'm going to make them a serialized field so you can see how it works. 04:08.810 --> 04:14.900 Let's do private Vector3 array waypoints equals to a new Vector3 of. 04:14.900 --> 04:16.010 And let's not do new. 04:16.010 --> 04:16.370 It's okay. 04:16.370 --> 04:17.990 We can do it in the inspector. 04:17.990 --> 04:21.260 And let's do private int way index. 04:21.260 --> 04:23.870 This is going to be very similar to the movement of the b. 04:24.020 --> 04:29.180 But uh, just wait a bit because I'm going to show you how different it is okay. 04:29.360 --> 04:30.770 Let's do waypoint. 04:32.220 --> 04:34.110 Uh, with a zero. 04:34.950 --> 04:42.870 Is equals to new Vector3 Transform.position minus travel distance divided by two. 04:42.900 --> 04:44.970 So only half of the travel distance. 04:46.030 --> 04:51.160 It should be dot x and then transform position dot y. 04:51.610 --> 04:54.220 Then we need same for the right side. 04:54.220 --> 04:58.060 So I'm going to do plus over here and waypoint one. 04:58.270 --> 05:04.990 Then let's take away index and make it equals to random range from zero to waypoint length. 05:04.990 --> 05:07.720 So it's going to choose a random direction at the start. 05:08.290 --> 05:10.060 And then let's set up um. 05:11.710 --> 05:12.880 Movement itself. 05:12.880 --> 05:13.360 Overwrite. 05:13.360 --> 05:14.260 Update. 05:15.470 --> 05:17.600 Handle movement. 05:17.630 --> 05:19.520 Nothing that we didn't do before. 05:20.760 --> 05:21.270 Sorry. 05:21.270 --> 05:24.720 That was my friend who made a sound. 05:24.720 --> 05:25.740 And then. 05:28.250 --> 05:30.260 We need to make something very simple. 05:30.260 --> 05:31.790 If can move. 05:32.430 --> 05:33.210 False. 05:33.690 --> 05:37.530 Then we return and then transform position. 05:41.550 --> 05:42.630 Equals to vector two. 05:42.630 --> 05:49.950 Move towards from transform.position to waypoint with away index, and as a speed we're going to use 05:49.950 --> 05:53.880 move speed multiplied by time dot delta time, same as before. 05:54.610 --> 05:56.320 Then we need to adjust the index. 05:56.320 --> 06:03.010 So if we are to the distance between transform.position and yeah, there's going to be the last time 06:03.010 --> 06:06.580 we type in this I promise because I'm kind of tired of it as well. 06:06.940 --> 06:08.440 Uh, maybe you're not. 06:08.440 --> 06:13.210 I am a little bit tired of using this statement. 06:14.750 --> 06:16.220 What did I do wrong here? 06:16.340 --> 06:18.680 It should be waypoints with array index. 06:22.330 --> 06:23.200 Okay. 06:23.200 --> 06:25.060 Then we index plus plus. 06:25.060 --> 06:31.060 And if we index is yes then we index is yes okay. 06:31.060 --> 06:32.260 This is what we should have. 06:33.110 --> 06:34.670 So this will make it move. 06:35.340 --> 06:37.410 Although we're not going to see how it moves. 06:37.410 --> 06:42.540 Let's do a handle flip into waypoint with away index. 06:44.300 --> 06:45.200 Dot x. 06:46.520 --> 06:50.060 Okay, uh, let's see how it moves left and right. 06:50.060 --> 06:53.660 But we're not going to see the distance until it flies. 06:53.660 --> 06:55.190 That is not very good for us. 06:55.190 --> 06:56.810 So I'm going to show you how to make. 06:57.790 --> 06:59.260 Uh, set up easier. 06:59.260 --> 07:02.200 But for now, let's just be sure it is working. 07:02.470 --> 07:03.880 I'm gonna give it, uh. 07:05.940 --> 07:07.830 Let's do gravity scale zero for now. 07:07.830 --> 07:08.790 Just for now. 07:08.790 --> 07:15.660 Keep rigid body dynamic and let's do Bluebird script travel distance eight waypoints two. 07:15.660 --> 07:19.140 Let's make lengths of 8.2 and let's go. 07:22.980 --> 07:24.090 It does not fly. 07:27.410 --> 07:29.060 Uh, something is wrong, I believe. 07:29.790 --> 07:30.270 Oh, yes. 07:30.270 --> 07:30.660 Okay. 07:30.660 --> 07:32.220 We need to assign variables. 07:32.670 --> 07:34.890 Let's drag ground check. 07:36.340 --> 07:37.450 Layer ground. 07:37.450 --> 07:38.590 This can be zero. 07:38.620 --> 07:40.570 This can be zero and this can be zero. 07:40.570 --> 07:42.460 And also we need to change it to. 07:43.910 --> 07:44.870 Uh, flying enemy? 07:44.870 --> 07:46.430 No, this object only. 07:47.030 --> 07:49.520 Okay, let's go and see this again. 07:51.600 --> 07:54.390 So there is a bird moves left and right. 07:54.390 --> 07:55.680 It's pretty much okay. 07:55.680 --> 07:57.270 And it works just like that. 07:57.270 --> 08:03.810 Although I would like to make it a bit more realistic, I want to make it heavy, so it's gonna pull 08:03.810 --> 08:05.040 while it flies. 08:05.040 --> 08:10.110 And then with each flap of wings, we're going to push it up a little bit. 08:10.620 --> 08:11.670 That's what I want to do. 08:11.670 --> 08:17.160 And also I want to make gizmos so I can see the waypoints it's going to use. 08:17.160 --> 08:19.740 So let's go to enemy Blue Bird. 08:21.410 --> 08:23.810 Now let's make a sterilized field. 08:23.810 --> 08:26.600 Private float lifeforce. 08:26.600 --> 08:29.450 I'm going to make it equals to 1.5 by default. 08:30.090 --> 08:33.360 And then we're going to make a method. 08:34.230 --> 08:36.630 Pilot would fly up. 08:37.390 --> 08:39.130 We're going to do something very simple. 08:39.160 --> 08:41.740 RB velocity equals to new vector two. 08:42.430 --> 08:46.630 RB velocity dot x and fly up fly force. 08:46.660 --> 08:47.380 Okay. 08:48.880 --> 08:50.620 We're going to use this method later. 08:50.620 --> 08:54.790 Now let's make gizmos so we can see how things are working. 08:56.610 --> 09:03.450 And we're going to need a private ball in play mode, which we're going to set to true in the start 09:03.450 --> 09:05.190 in play mode equals to true. 09:05.220 --> 09:10.320 We need this because we want to draw gizmos to the same position, but we cannot do it inside of on 09:10.320 --> 09:15.630 draw gizmos because on draw gizmos is called inside of the editor and start is not. 09:15.630 --> 09:18.000 So these variables would be empty. 09:18.210 --> 09:19.500 And because of that. 09:20.380 --> 09:26.380 We need to make new variables inside of Android gizmos and then stop using them if we are in the play 09:26.380 --> 09:26.860 mode. 09:26.890 --> 09:28.750 Also, let's do a. 09:30.870 --> 09:33.300 Equals to new vector two with a size of two. 09:33.330 --> 09:34.890 So now we can hide it. 09:34.890 --> 09:37.620 And we don't need to see it because we know it is working. 09:37.620 --> 09:40.920 And we did see difference in the position on the x. 09:43.490 --> 09:45.980 Okay, let's go and override Ondraw gizmos. 09:45.980 --> 09:49.730 And this is going to be the last thing we need to do for the bird and draw gizmos. 09:52.200 --> 09:53.460 Um, sorry. 09:53.460 --> 09:57.300 We need to do override Ondraw gizmos and then. 09:58.020 --> 10:05.820 If in play mode is false, then float distance equals to a travel distance divided by two. 10:08.800 --> 10:10.690 Then we're going to do vector three. 10:12.050 --> 10:21.920 Left position equals to new Vector3 from transform position dot x minus distance transform position 10:21.920 --> 10:24.980 dot y and we want to duplicate it. 10:26.760 --> 10:31.020 Do it as a right position. 10:32.200 --> 10:34.600 Lines, distance and gizmos. 10:34.600 --> 10:41.260 We're going to draw a line between them and we're going to do, um, a small sphere so we can see it 10:41.260 --> 10:41.950 as well. 10:42.340 --> 10:43.210 Gizmos. 10:44.180 --> 10:53.060 Draw wire sphere at left position with a 0.5 F, and then right position with a 0.5 F. 10:55.880 --> 10:57.740 And then let's do else. 10:57.740 --> 11:02.540 And inside we can just duplicate this. 11:05.490 --> 11:06.540 Like that. 11:07.190 --> 11:08.060 And. 11:08.770 --> 11:11.440 Uh, actually, I'm sorry. 11:11.440 --> 11:17.350 We don't need this because we can use transform position. 11:18.210 --> 11:25.230 To the, uh, waypoint with a zero and then transform position to the waypoint of one. 11:25.230 --> 11:28.380 So it's going to draw from a bird to the waypoints. 11:28.380 --> 11:29.670 It's going to be connected. 11:31.610 --> 11:36.950 And then over here we can do waypoints zero and waypoints one. 11:40.140 --> 11:42.480 All right, let's save this. 11:42.480 --> 11:44.430 And we have fly up method. 11:45.690 --> 11:47.010 Which is over here. 11:47.010 --> 11:48.900 Now we can go back to unity. 11:50.300 --> 11:55.160 Let's go to project asset Animations enemies Bluebird. 11:55.700 --> 11:57.830 For the heat we need to uncheck loop time. 11:57.830 --> 12:00.680 Then we need to go to Animation Find. 12:00.890 --> 12:01.250 Uh. 12:03.460 --> 12:04.060 Lie. 12:04.060 --> 12:06.880 And let's find the sprite where it flaps the wings. 12:06.880 --> 12:09.430 And it happens over here. 12:09.790 --> 12:12.040 So over here it should gain a velocity. 12:12.040 --> 12:15.850 Let's add event and do methods fly up. 12:17.670 --> 12:18.810 Uh, yeah, just like that. 12:18.810 --> 12:20.010 It's going to be nice. 12:20.010 --> 12:22.500 Now let's go to this object. 12:22.500 --> 12:25.050 Also, it should be renamed to Enemy Bluebird. 12:27.450 --> 12:32.280 And yeah, I forgot to mention, now we can see gizmos, how it should fly from left to right. 12:32.460 --> 12:35.040 And we can make it heavy on the rigid body. 12:35.040 --> 12:40.680 Let's give it gravity scale of one, for example, and fly force 1.5. 12:40.680 --> 12:41.490 So it should be good. 12:41.490 --> 12:43.080 Let's go and try this. 12:43.080 --> 12:43.980 Let's see it. 12:45.790 --> 12:48.910 Now you can see Byrd is heavy is going down. 12:48.910 --> 12:53.800 And with the flap of wings it's going up and it looks a bit more realistic. 12:53.800 --> 12:56.200 If you want you can add fly force. 12:58.460 --> 13:00.080 Now it's not that heavy. 13:00.080 --> 13:03.080 So maybe you should increase the gravity scale. 13:04.450 --> 13:06.610 Yeah, this also could exist. 13:07.140 --> 13:08.100 Why not? 13:10.390 --> 13:11.560 So this is the idea. 13:11.560 --> 13:13.150 This is the bird I want to have. 13:13.150 --> 13:15.100 I kind of like how it works. 13:15.460 --> 13:20.110 Uh, it feels like it's heavy and it feels like it's really flying only when it flaps the wings. 13:20.230 --> 13:23.590 Okay, I'm going to do gravity scale two fly force. 13:23.590 --> 13:25.360 I'm going to do, um. 13:26.560 --> 13:27.370 Maybe three. 13:27.370 --> 13:28.900 Let me keep it like that for now. 13:29.230 --> 13:30.040 And that's it. 13:30.040 --> 13:32.260 Let's go to asset prefabs. 13:32.350 --> 13:33.100 Enemies. 13:33.100 --> 13:35.080 Let's make it as a prefab. 13:36.090 --> 13:38.280 And also before I forgot. 13:38.280 --> 13:40.080 Let's go to the script. 13:43.380 --> 13:47.670 Let's override animator and let's keep it empty like that. 13:48.150 --> 13:49.170 All right. 13:49.290 --> 13:51.090 Thank you so much for paying attention. 13:51.090 --> 13:52.950 And I'll see you in the next video.
