1
00:00:02,050 --> 00:00:02,410
All right.

2
00:00:02,410 --> 00:00:06,670
So in this video, I just want to take a quick look at the attachment instance.

3
00:00:06,910 --> 00:00:12,070
And the attachment is basically an instance that defines a point, an orientation that's relative to

4
00:00:12,070 --> 00:00:14,140
its parent, which has to be a part.

5
00:00:14,500 --> 00:00:21,280
So, for example, here, if I take my part here and I put an attachment inside of it, I can see my

6
00:00:21,280 --> 00:00:23,410
attachment here in the center of my part.

7
00:00:23,410 --> 00:00:28,120
And right here we have a see frame in my attachment as well as the world C frame.

8
00:00:28,120 --> 00:00:31,270
So this is the global position of my attachment.

9
00:00:31,270 --> 00:00:33,330
It follows the position of my part.

10
00:00:33,340 --> 00:00:35,500
So if I move my part around here.

11
00:00:36,170 --> 00:00:41,600
You can see that the positioning for the world C frame of my attachment changes as well, but it also

12
00:00:41,600 --> 00:00:46,090
has another C frame property here that stores the offset relative to this part.

13
00:00:46,100 --> 00:00:55,970
So if I were to move this, let's say like that, you see I am -8.95 from the origin of my parent part

14
00:00:55,970 --> 00:00:57,410
on the x axis.

15
00:00:57,980 --> 00:01:00,770
You can also rotate these attachments as well.

16
00:01:03,270 --> 00:01:08,300
And attachments are useful because we can use them as a point for like particle emitters.

17
00:01:08,310 --> 00:01:13,960
So instead of a particle emitter emanating from this part, it just comes out of the attachment.

18
00:01:13,980 --> 00:01:18,330
You can also use them with lights, which we'll learn in a little bit, and you can also use them for

19
00:01:18,330 --> 00:01:18,750
sound.

20
00:01:18,770 --> 00:01:23,790
So if I put a sound in here, the origin of this sound would come from the attachment and not the part

21
00:01:23,790 --> 00:01:24,600
itself.

22
00:01:25,290 --> 00:01:29,990
The attachment is also required in several other instances, including constraints.

23
00:01:30,000 --> 00:01:32,760
So you'll end up using attachments quite often.

24
00:01:32,760 --> 00:01:35,520
And I just wanted to show them to you real quick in this video.
