12 00:00:30,000 --> 00:00:34,000 That is happening because of the collider. 13 00:00:34,000 --> 00:00:35,000 So you can see. 14 00:00:37,000 --> 00:00:39,000 We can see my collider is really big. 15 00:00:39,000 --> 00:00:49,000 And if you remember shape of the object defined not by the sprite over here, not by the sprite, but 16 00:00:49,000 --> 00:00:50,000 by the collider. 17 00:00:52,000 --> 00:00:57,000 So what we can do about this is something very simple and easy to do. 18 00:00:57,000 --> 00:01:00,000 Let's go to player animations. 19 00:01:00,000 --> 00:01:01,000 Find. 20 00:01:02,000 --> 00:01:03,000 Idle. 21 00:01:03,000 --> 00:01:05,000 And we're going to zoom it in. 22 00:01:07,000 --> 00:01:11,000 And first we want to record size of the collider how it's supposed to be. 23 00:01:11,000 --> 00:01:17,000 So when the first frame of the idle animation played, we're going to return the size of the collider 24 00:01:17,000 --> 00:01:20,000 how it was before or how we set it to be. 25 00:01:20,000 --> 00:01:26,000 So let's click this record button and to make it record any changes, we actually need to change something, 26 00:01:26,000 --> 00:01:28,000 but I don't want to change the values. 27 00:01:28,000 --> 00:01:31,000 So what I want to do here is to make. 28 00:01:32,000 --> 00:01:38,000 Size on the X, let's say 1.1 and then return it to one. 29 00:01:38,000 --> 00:01:41,000 So one and now we recorded one. 30 00:01:41,000 --> 00:01:43,000 Now we need to record this one as well. 31 00:01:43,000 --> 00:01:45,000 I'll change it and I'll change it back. 32 00:01:46,000 --> 00:01:50,000 And we want to fix that. 33 00:01:50,000 --> 00:01:51,000 I guess it's fine. 34 00:01:51,000 --> 00:01:52,000 It's okay. 35 00:01:52,000 --> 00:01:53,000 Let it be like that. 36 00:01:54,000 --> 00:01:56,000 Now we need to record offset as well. 37 00:01:56,000 --> 00:02:02,000 So it's zero and for the y89. 38 00:02:02,000 --> 00:02:05,000 So now value is the same and they are recorded over here. 39 00:02:06,000 --> 00:02:09,000 Let's click this record button that is done. 40 00:02:09,000 --> 00:02:12,000 So now if we go to. 41 00:02:13,000 --> 00:02:15,000 And let's say other animation. 42 00:02:16,000 --> 00:02:17,000 And change the collider. 43 00:02:17,000 --> 00:02:21,000 Or even if we change it now, let's try to do that. 44 00:02:21,000 --> 00:02:21,000 I'll. 45 00:02:23,000 --> 00:02:25,000 I'll decrease size on the X like that. 46 00:02:26,000 --> 00:02:33,000 Now, look, when I'll hit the play mode, I'll enter my idle animation and collider size will be changed 47 00:02:33,000 --> 00:02:34,000 to what we said before. 48 00:02:35,000 --> 00:02:36,000 Boom. 49 00:02:36,000 --> 00:02:37,000 You can see that right?
