1
00:00:01,370 --> 00:00:01,850
All right.

2
00:00:01,850 --> 00:00:07,520
So in this video, I just want to take a deeper dive into parts so you can check out all the other properties

3
00:00:07,520 --> 00:00:09,920
parts have that you can use and manipulate.

4
00:00:10,280 --> 00:00:12,200
So I'll just make a part here my game.

5
00:00:12,890 --> 00:00:16,610
And as you can tell, we have loads of properties we can manipulate here.

6
00:00:16,640 --> 00:00:20,190
Now, you obviously know we can change the color of a part to whatever we want.

7
00:00:20,210 --> 00:00:22,390
Like maybe a nice blue.

8
00:00:22,400 --> 00:00:27,680
Or you can select the color from bright color here to one of the predefined colors that robots has.

9
00:00:28,650 --> 00:00:31,950
Of course, there's this other property here called Cash Shadow.

10
00:00:31,950 --> 00:00:37,290
And this basically tells the game whether or not you want this part to have a shadow casted from it.

11
00:00:37,830 --> 00:00:40,200
So if I move my part up here, you see, it's got a shadow.

12
00:00:40,200 --> 00:00:42,630
But if I turn it off, the shadow is gone.

13
00:00:44,290 --> 00:00:46,900
We can also change the material, of course.

14
00:00:47,920 --> 00:00:50,020
Maybe I want to stand part.

15
00:00:50,920 --> 00:00:57,040
And then here for material variant, it allows you to change the material to a different variant of

16
00:00:57,040 --> 00:00:58,930
a material using material service.

17
00:00:58,960 --> 00:01:02,230
We'll go over this later when we learn more about the material service.

18
00:01:03,170 --> 00:01:07,550
Reflectance is basically, yeah, there's a little pop up menu there.

19
00:01:07,550 --> 00:01:10,720
So if you hover over a property, you don't really know what it does.

20
00:01:10,730 --> 00:01:13,460
It gives you a little description of what the property does.

21
00:01:13,460 --> 00:01:18,950
So Reflectance is basically how shiny you want the part to be, and it only works on parts that use

22
00:01:18,950 --> 00:01:21,320
plastic or glass as the material.

23
00:01:21,590 --> 00:01:25,880
So if we set it to one, obviously you can't see it at all here on the sand.

24
00:01:25,880 --> 00:01:28,490
So we've got to change it to either plastic or glass.

25
00:01:28,610 --> 00:01:30,110
We'll just pick plastic.

26
00:01:31,350 --> 00:01:31,850
Okay.

27
00:01:32,400 --> 00:01:34,140
So I do like one.

28
00:01:34,530 --> 00:01:34,950
Okay.

29
00:01:34,980 --> 00:01:35,700
There we go.

30
00:01:36,000 --> 00:01:38,190
We have a very shiny part.

31
00:01:38,190 --> 00:01:41,950
It's basically chrome as the property states.

32
00:01:41,970 --> 00:01:47,880
A value of one is completely reflective, and then zero is just the default plastic.

33
00:01:48,180 --> 00:01:51,450
So no reflectance and we can tweak it.

34
00:01:51,450 --> 00:01:56,010
Maybe we want it to be more reflective to the point where it turns into a chrome brick.

35
00:01:56,010 --> 00:01:57,150
So that's kind of cool.

36
00:01:57,930 --> 00:02:01,620
Of course, transparency, how transparent you want your block to be.

37
00:02:01,620 --> 00:02:05,490
So one is fully transparent, completely invisible.

38
00:02:06,930 --> 00:02:09,000
While you can give it float numbers in between.

39
00:02:09,000 --> 00:02:11,610
So my part's half invisible.

40
00:02:11,610 --> 00:02:12,840
We can see right through it.

41
00:02:13,110 --> 00:02:15,630
And of course, zero can't see through it at all.

42
00:02:16,800 --> 00:02:17,940
Archival.

43
00:02:17,940 --> 00:02:23,310
This is a property for like if you want this instance to save when you publish the game, you won't

44
00:02:23,310 --> 00:02:24,720
ever really need to use this.

45
00:02:24,720 --> 00:02:29,340
This is more for like plugins that create stuff and then delete them or don't want them to be saved

46
00:02:29,340 --> 00:02:31,200
when a person publishes their game.

47
00:02:31,200 --> 00:02:33,450
So just kind of ignore this property.

48
00:02:33,810 --> 00:02:39,390
Of course, locked is whether or not you want this part to be clicked on or you can access it.

49
00:02:39,390 --> 00:02:44,370
So if I enable locked here and then I select my part, I can't click it anymore.

50
00:02:44,580 --> 00:02:45,600
I can't select it.

51
00:02:45,600 --> 00:02:50,340
But of course I can unlock it using this tool up here, of course, right here holds the name property

52
00:02:50,340 --> 00:02:54,780
for the part so I can name it to whatever I want, like blah blah parent.

53
00:02:54,780 --> 00:02:59,310
I can set the parent of the part, whichever instance I want to select, it will be the parent of my

54
00:02:59,310 --> 00:02:59,850
part.

55
00:03:01,040 --> 00:03:07,670
Um, here I can set the size of my part, so maybe I want it to be two studs on the y axis, maybe ten

56
00:03:07,670 --> 00:03:09,740
on the Z axis, something like that.

57
00:03:10,040 --> 00:03:16,190
And of course, here in the C frame is where we can adjust both the position and the orientation of

58
00:03:16,190 --> 00:03:16,640
our part.

59
00:03:16,640 --> 00:03:20,050
So maybe I want to rotate it like 90 degrees around the Y axis.

60
00:03:20,060 --> 00:03:21,770
Boom, I can do it like that.

61
00:03:22,220 --> 00:03:25,340
And of course here you can adjust the position of your part.

62
00:03:25,340 --> 00:03:27,560
So maybe I want it to be higher up five.

63
00:03:27,590 --> 00:03:32,990
You can also adjust these using the tools we have, like the rotate tool and the move tool.

64
00:03:33,730 --> 00:03:39,100
Down here is origin, which is the origin of the parts, basically the same as the sea frame holds the

65
00:03:39,100 --> 00:03:41,680
position and the orientation of the origin.

66
00:03:41,710 --> 00:03:43,840
You don't really need to mess with this at all.

67
00:03:45,270 --> 00:03:48,480
And then down here we have the pivot where we can offset it.

68
00:03:48,480 --> 00:03:52,390
And if you remember in our model tab, if we go to the edit pivot button.

69
00:03:52,410 --> 00:03:57,450
See, we can move the pivot around and as you can see, it updates the values in the bottom, right?

70
00:03:57,600 --> 00:03:59,370
We can rotate the pivot.

71
00:04:00,260 --> 00:04:02,940
And that's basically what these values hold for our pivot.

72
00:04:02,960 --> 00:04:05,720
And of course, we can hit reset to put it back in place.

73
00:04:06,430 --> 00:04:07,100
What else is there?

74
00:04:07,120 --> 00:04:10,090
We got collision so four can collide.

75
00:04:10,360 --> 00:04:13,390
It's basically telling you whether or not you want stuff to collide with this part.

76
00:04:13,390 --> 00:04:15,130
If I disable, can collide.

77
00:04:16,070 --> 00:04:17,120
No other part.

78
00:04:17,150 --> 00:04:17,790
No player?

79
00:04:17,810 --> 00:04:18,020
No.

80
00:04:18,020 --> 00:04:20,150
Nothing will be able to collide with the part.

81
00:04:20,780 --> 00:04:29,480
This can query button is for something called ray casts, which basically fires an arrow at a defined

82
00:04:29,480 --> 00:04:30,020
distance.

83
00:04:30,020 --> 00:04:34,130
And if it hits something and lets you know if this property is enabled, that means if I fired a ray

84
00:04:34,130 --> 00:04:38,150
cast towards the direction of this part and it hit the part, it would be like, okay, there's a part

85
00:04:38,150 --> 00:04:42,590
here, but if I disable it, the ray cast will go straight through the part like it didn't exist.

86
00:04:42,590 --> 00:04:47,840
So that's kind of what the purpose of this property is and then can touch this for the touched event.

87
00:04:47,840 --> 00:04:51,440
Basically, whether or not you want the touch to fire for this part.

88
00:04:51,650 --> 00:04:56,300
And collision group, you can select the collision group for the part and we'll learn more about those

89
00:04:56,300 --> 00:04:56,930
later.

90
00:04:57,690 --> 00:04:58,730
Of course, anchored.

91
00:04:58,730 --> 00:05:00,920
Whether or not you want this part to be anchored in place.

92
00:05:00,920 --> 00:05:04,310
So right now my part is unanchored and can collide is off.

93
00:05:04,310 --> 00:05:06,440
So if I want to go run my game.

94
00:05:07,510 --> 00:05:10,090
Falls through the floor and disappears.

95
00:05:12,160 --> 00:05:15,670
When we turn can collide back on and run it.

96
00:05:15,850 --> 00:05:19,360
So my part's on anchored, and as you can see, it can move around.

97
00:05:20,490 --> 00:05:22,470
But if I anchor it in place.

98
00:05:24,190 --> 00:05:26,560
Then it stays where it needs no force.

99
00:05:26,590 --> 00:05:28,570
No gravity is acting on this part.

100
00:05:29,330 --> 00:05:30,680
What else we got in here?

101
00:05:30,710 --> 00:05:32,750
We got some custom physical properties.

102
00:05:32,750 --> 00:05:38,450
You can change the density of the part, elasticity, the friction, how much friction?

103
00:05:38,450 --> 00:05:40,190
It applies to another surface.

104
00:05:40,220 --> 00:05:43,760
This is kind of more advanced stuff we're not going to get that deep into.

105
00:05:44,030 --> 00:05:49,970
So the mass loss property is basically for if I weld this part to another part, do I want to add the

106
00:05:49,970 --> 00:05:52,280
mass of this part to the Weld part?

107
00:05:52,310 --> 00:05:55,610
If I uncheck massless, that means it will keep its mass.

108
00:05:55,610 --> 00:06:00,980
When it's welded to another part, it will add its mass to the total collective mass of all the parts.

109
00:06:00,980 --> 00:06:05,720
But if mass loss was checked, then it means it would have no mass when it's welded to another part

110
00:06:05,720 --> 00:06:06,890
that has mass.

111
00:06:07,750 --> 00:06:08,920
Route priority.

112
00:06:08,920 --> 00:06:14,590
It's basically used to determine the route part of an assembly, which I'll talk about in a little bit.

113
00:06:14,590 --> 00:06:16,900
But you don't have to worry about this property for now.

114
00:06:17,140 --> 00:06:18,910
And then here we got the shape.

115
00:06:18,910 --> 00:06:24,370
Of course we can change it to maybe like a ball or maybe we want to change it to a cylinder or just

116
00:06:24,370 --> 00:06:25,540
keep it at a block.

117
00:06:25,540 --> 00:06:28,240
That's just kind of how we do it here.

118
00:06:28,540 --> 00:06:33,130
And this last section here is for forces You want to apply on the part, and this one's kind of cool.

119
00:06:33,460 --> 00:06:39,760
So here it's basically telling you what direction and how much of a force you want to apply to an unanchored

120
00:06:39,760 --> 00:06:40,330
part.

121
00:06:40,390 --> 00:06:42,250
So this part has to be unanchored.

122
00:06:42,250 --> 00:06:45,430
Otherwise we can't apply forces or velocities on it.

123
00:06:45,430 --> 00:06:51,490
But if I want to run my game here and I select my part, I can apply a velocity like in the Y direction,

124
00:06:51,490 --> 00:06:55,780
the global y axis like 20 and I can make my part jump.

125
00:06:56,170 --> 00:06:56,830
Look at that.

126
00:06:57,640 --> 00:06:59,680
Of course I can increase the velocity.

127
00:06:59,680 --> 00:07:00,790
Maybe I want to jump.

128
00:07:01,870 --> 00:07:02,700
There we go.

129
00:07:02,710 --> 00:07:04,030
Moves around a bit.

130
00:07:04,690 --> 00:07:09,730
Of course I can do it in the x direction, so we'll do something like that.

131
00:07:09,730 --> 00:07:11,620
Moves just a little bit.

132
00:07:11,620 --> 00:07:16,390
And of course you can also apply rotational velocities, this angular velocity.

133
00:07:16,600 --> 00:07:20,290
And maybe I want to apply a force to rotate it in the X direction.

134
00:07:20,290 --> 00:07:22,600
So I'll do 100 and see what happens.

135
00:07:22,600 --> 00:07:23,470
Oh goodness.

136
00:07:25,320 --> 00:07:27,210
So yeah, these ones, these ones are pretty neat.

137
00:07:27,210 --> 00:07:30,480
You can just apply random forces to it to unanchored parts.

138
00:07:30,480 --> 00:07:34,020
Remember, if it's anchored, you don't get to apply any force to it.

139
00:07:34,410 --> 00:07:39,090
So maybe I'll apply a force X and Y direction and look at that.

140
00:07:39,090 --> 00:07:40,320
My part jumps.

141
00:07:40,860 --> 00:07:41,940
I'll do it again here.

142
00:07:43,780 --> 00:07:44,380
Look at that.

143
00:07:46,280 --> 00:07:49,070
That's basically the gist of parts in their properties.

144
00:07:49,070 --> 00:07:51,140
So I'll see you in the next lecture.
