WEBVTT 00:00.020 --> 00:00.500 Hello guys. 00:00.500 --> 00:01.490 Welcome to the video. 00:01.490 --> 00:06.950 In this one I want to show you how to work with a blend tree and how blend tree can be useful in the 00:06.950 --> 00:08.090 animator at all. 00:08.090 --> 00:11.210 So first let's create a blend tree and see what it does. 00:11.210 --> 00:13.160 We're going to click create button over here. 00:13.160 --> 00:16.070 Create state from New Blend Tree. 00:16.070 --> 00:21.410 Now let's select it and name it as Idle Slash Move. 00:22.470 --> 00:27.810 And inside you can select the blend tree and you can add a bunch of motions. 00:27.810 --> 00:30.090 Here I'm going to click add motion. 00:30.420 --> 00:31.470 Add motion. 00:31.500 --> 00:32.550 Add motion. 00:34.030 --> 00:35.710 Now let's select. 00:36.430 --> 00:37.630 Player move. 00:38.250 --> 00:42.090 Layer idol and layer move. 00:42.570 --> 00:50.790 We can open preview over here and if we click play button you can see animation being played. 00:50.850 --> 00:54.000 Now let's uncheck Automate threshold over here. 00:58.860 --> 01:01.560 And let's do minus one. 01:02.590 --> 01:04.780 Zero one. 01:05.310 --> 01:10.710 Now this threshold will control transition between animations by itself. 01:10.890 --> 01:17.460 So if we have value at zero, then player will stand in the idle animation. 01:17.460 --> 01:20.610 If we move value to the left to the negative value. 01:20.640 --> 01:26.040 You can see player is in the running animation if we go back to zero. 01:27.830 --> 01:29.630 He stands in the idol. 01:29.630 --> 01:33.470 If we increase the value, he goes to the running animation again. 01:35.690 --> 01:43.880 And this can be used to control idle and move animation instead of these two animations with the transitions. 01:43.910 --> 01:46.400 All right, let's just go inside. 01:47.110 --> 01:50.470 And we need to rename this parameter over here. 01:50.470 --> 01:53.380 I'm going to name it as x velocity. 01:54.320 --> 01:57.680 And then we need to be sure this parameter is selected over here. 02:01.270 --> 02:02.320 X velocity. 02:02.350 --> 02:05.380 Now let's go back to base layer. 02:05.380 --> 02:06.910 We can delete these two. 02:06.940 --> 02:09.490 I just wanted to show you an example on how it could work. 02:09.490 --> 02:10.930 But don't be sorry. 02:10.930 --> 02:12.160 Just remove them. 02:12.220 --> 02:17.770 And this blend tree will become a default state animation of the player. 02:17.800 --> 02:25.030 We can delete this parameter as well, and we can only update this animation by updating info on the 02:25.030 --> 02:26.170 x velocity. 02:26.170 --> 02:30.130 And that would do the entire job for us with the transitions. 02:30.130 --> 02:31.420 Very convenient way. 02:31.420 --> 02:32.680 Very clean I think. 02:32.680 --> 02:33.640 Very efficient. 02:33.880 --> 02:35.980 So let's go to player script. 02:37.010 --> 02:41.780 And over here, instead of setting boolean, we can just type. 02:42.610 --> 02:46.690 Einem said float of the x velocity. 02:46.690 --> 02:48.820 And again I'm scared I'll make a mistake. 02:48.820 --> 02:50.920 So I'll go here. 02:50.920 --> 02:57.010 I'll copy this, go back to script, paste this in, and then as a value that we want to have for that 02:57.010 --> 03:00.220 parameter we're going to pass rb velocity dot x. 03:00.730 --> 03:01.630 And that's it. 03:02.140 --> 03:03.610 Simple as that. 03:03.700 --> 03:07.480 Now let's save this and go back to unity. 03:08.530 --> 03:10.510 And see if it's working. 03:13.510 --> 03:14.320 Idol. 03:14.890 --> 03:15.760 Move. 03:17.400 --> 03:19.200 Mauve idol. 03:19.410 --> 03:20.550 Very cool. 03:20.550 --> 03:21.690 Love it so much, man. 03:21.720 --> 03:22.770 Really nice. 03:23.130 --> 03:27.510 Um, I can see there is a bit of a jittering effect when we move in. 03:27.510 --> 03:30.660 You can see on the character he sort of jittering. 03:31.920 --> 03:34.470 To fix that, we can go to the rigid body. 03:35.820 --> 03:39.570 And go to interpolate and choose interpolate. 03:39.900 --> 03:43.320 Now when we move, it's going to feel smooth and nice. 03:43.860 --> 03:45.990 It has to do with the update of a physics. 03:45.990 --> 03:47.910 It's not that important right now. 03:51.470 --> 03:52.340 All right. 03:52.580 --> 03:53.690 Very good. 03:53.690 --> 03:56.030 Oh, we need to do this out of the play mode. 03:56.030 --> 03:57.650 Let's do interpolate here. 03:58.280 --> 03:58.790 Okay? 03:58.790 --> 03:59.150 Okay. 03:59.150 --> 04:00.350 This is good enough. 04:00.350 --> 04:02.720 I think we did a good job for this video. 04:02.720 --> 04:05.840 It was very short but very important I think. 04:05.840 --> 04:08.900 And yeah I think that's it for now. 04:08.900 --> 04:10.220 Let's go to the next video.
