1
00:00:01,630 --> 00:00:01,910
Okay.

2
00:00:01,960 --> 00:00:05,400
So in this video, we're going to continue looking at roadblocks, instances.

3
00:00:05,410 --> 00:00:10,120
And this is going to be all about point lights, spotlights and surface lights, which you'll use a

4
00:00:10,120 --> 00:00:11,810
lot in your games for lighting.

5
00:00:11,830 --> 00:00:16,120
So in order to actually see these lights very well, I'm actually going to go into the lighting service

6
00:00:16,120 --> 00:00:18,070
here and set the time of day to like.

7
00:00:18,940 --> 00:00:19,720
Zero.

8
00:00:20,170 --> 00:00:20,620
There we go.

9
00:00:20,620 --> 00:00:22,000
Now it's nice and dark.

10
00:00:22,000 --> 00:00:23,260
We're at nighttime.

11
00:00:23,620 --> 00:00:25,230
And now with my part here, I.

12
00:00:26,080 --> 00:00:29,380
I'm going to insert what should our first one be?

13
00:00:30,490 --> 00:00:31,460
Let's do a point light.

14
00:00:31,480 --> 00:00:32,020
Why not?

15
00:00:34,080 --> 00:00:37,590
So with our point light, as you can see, it's not doing much.

16
00:00:37,590 --> 00:00:42,900
But if I bring this part down towards the ground, you'll see it actually is slightly illuminated in

17
00:00:42,900 --> 00:00:43,740
the ground.

18
00:00:43,770 --> 00:00:48,240
It's not very bright, though, and that's because our range is quite small and our brightness isn't

19
00:00:48,240 --> 00:00:48,990
that much.

20
00:00:49,050 --> 00:00:53,070
But using the brightness, we can actually increase the intensity of light.

21
00:00:53,070 --> 00:00:58,790
So if I put it to 20, it is very bright now, or if I want it to be very dim, I can put maybe like

22
00:00:58,800 --> 00:00:59,670
0.1.

23
00:00:59,790 --> 00:01:02,040
And this is a very dim light.

24
00:01:02,040 --> 00:01:08,310
It's like it's virtually impossible to see right now, but I'll set it to like maybe five for now.

25
00:01:08,790 --> 00:01:11,100
And then I can change the range of my light.

26
00:01:11,100 --> 00:01:15,900
So maybe instead of eight studs in all directions, maybe I want it to be like 16.

27
00:01:16,920 --> 00:01:18,480
And it's a little bright there in the center.

28
00:01:18,510 --> 00:01:20,520
So I'll tone down the brightness to maybe two.

29
00:01:21,560 --> 00:01:22,440
There we go.

30
00:01:22,460 --> 00:01:23,750
Here's our point light.

31
00:01:23,780 --> 00:01:27,050
It originates from a point, the center point of our part.

32
00:01:27,050 --> 00:01:28,700
And we can change the color of our light.

33
00:01:28,730 --> 00:01:32,700
Maybe we want it to be like an ominous red color.

34
00:01:32,720 --> 00:01:33,840
Spooky.

35
00:01:33,860 --> 00:01:38,480
And of course, we can enable or disable whether or not we want this light to interact with parts to

36
00:01:38,480 --> 00:01:39,710
create shadows.

37
00:01:39,980 --> 00:01:43,520
So if I turn shadows on, that means if I create another part here.

38
00:01:44,870 --> 00:01:45,860
You'll see.

39
00:01:47,010 --> 00:01:49,590
That is causing a shadow here.

40
00:01:51,040 --> 00:01:51,370
Oh.

41
00:01:53,210 --> 00:01:57,400
And we're getting this nice reflectance of a little bit of red into our shadow.

42
00:01:57,410 --> 00:02:01,100
But if I turn shadows off on our part, where is it?

43
00:02:01,130 --> 00:02:01,790
Here we go.

44
00:02:02,150 --> 00:02:03,170
Turn it off.

45
00:02:03,500 --> 00:02:04,220
You'll see.

46
00:02:04,220 --> 00:02:06,230
It just kind of goes right through our part.

47
00:02:06,440 --> 00:02:09,050
The light kind of acts as if this part doesn't exist.

48
00:02:09,050 --> 00:02:13,220
And the reason this is still cast in a shadow is probably because of our moon up there.

49
00:02:13,220 --> 00:02:15,680
But this shadow is coming from the moon.

50
00:02:16,940 --> 00:02:18,510
Let's try Spotlight.

51
00:02:18,530 --> 00:02:19,610
This one's kind of neat.

52
00:02:20,150 --> 00:02:25,790
So with a spotlight, it creates a light that is like a spotlight.

53
00:02:25,880 --> 00:02:28,670
Right now it's pointing in the front direction.

54
00:02:28,670 --> 00:02:31,310
But I can make it go where it's shooting downwards.

55
00:02:31,790 --> 00:02:34,040
And of course, I can change the range of the spotlight.

56
00:02:34,040 --> 00:02:38,990
So let's make it at, like, I don't know, 35 studs.

57
00:02:39,230 --> 00:02:41,620
So now it's shooting out this giant spotlight.

58
00:02:41,630 --> 00:02:46,430
But maybe I want this light to be more concentrated so I can go in here and change the angle and reduce

59
00:02:46,430 --> 00:02:47,930
it to maybe like 40.

60
00:02:49,440 --> 00:02:55,200
And I'll decrease the range a bit back to 30 and then I can increase the intensity of my light.

61
00:02:55,200 --> 00:02:57,270
So maybe I want it to be super bright.

62
00:02:57,540 --> 00:02:58,440
How about ten?

63
00:02:59,040 --> 00:02:59,760
There we go.

64
00:02:59,790 --> 00:03:02,820
Now we have our bright spotlight here.

65
00:03:04,260 --> 00:03:07,380
Cast in a nice light downwards.

66
00:03:07,860 --> 00:03:11,400
You can see this nice little image of what our spotlight looks like.

67
00:03:12,800 --> 00:03:19,040
And of course, I can also change the color here to maybe we'll make it a nice blue color.

68
00:03:19,940 --> 00:03:24,830
And of course, we can change whether or not we'd like this to respect shadows.

69
00:03:24,830 --> 00:03:26,270
So if I turn it on.

70
00:03:27,520 --> 00:03:31,240
You'll see that it is reflected in the top.

71
00:03:31,240 --> 00:03:36,220
And it's more dim down here because there's only a little bit of light spillover coming from the sides.

72
00:03:36,760 --> 00:03:40,720
But if I turn it off, you'll see it doesn't care that the part is there.

73
00:03:40,720 --> 00:03:42,220
It will go straight through.

74
00:03:43,340 --> 00:03:48,710
Now, you kind of noticed that this shadow option isn't affecting much and it's mostly prominent.

75
00:03:48,710 --> 00:03:51,210
You'll actually be able to see the most out of the sliding.

76
00:03:51,230 --> 00:03:53,840
If we switch the technology to future.

77
00:03:55,020 --> 00:03:58,350
And as you can see, this is much more realistic lighting.

78
00:03:58,350 --> 00:04:04,020
And now with shadows on it is respecting this part and no light is bleeding through.

79
00:04:04,260 --> 00:04:08,220
So this is a much better demonstration of the shadow property here.

80
00:04:08,220 --> 00:04:13,410
I'm using future lighting, which is a more realistic lighting, technology and robotics.

81
00:04:13,680 --> 00:04:18,870
And as you can see, if I have shadows off light passes straight through this object, but if I turn

82
00:04:18,870 --> 00:04:21,420
it on, it respects this object.

83
00:04:21,420 --> 00:04:24,920
And actually you can see a clean cut right through the center of this light.

84
00:04:24,930 --> 00:04:28,260
So that's just kind of the difference between shadows on and shadows off.

85
00:04:29,070 --> 00:04:32,460
And the last letter I want to show here is called a surface Light.

86
00:04:32,970 --> 00:04:37,970
And this produces light emanating directly from whichever surface of the part.

87
00:04:37,980 --> 00:04:41,290
So imagine this entire face of the part shooting off light.

88
00:04:41,310 --> 00:04:47,550
So if I put this on the bottom and I increase the brightness to five and increase the range to like.

89
00:04:49,320 --> 00:04:50,370
40?

90
00:04:50,520 --> 00:04:51,520
No, 30?

91
00:04:51,540 --> 00:04:51,890
Sure.

92
00:04:51,900 --> 00:04:52,590
Something like that.

93
00:04:52,590 --> 00:04:53,610
Super bright.

94
00:04:53,610 --> 00:04:58,950
It is shooting light out in all directions from this entire face of the part.

95
00:04:59,580 --> 00:05:04,350
And of course, if I turn on shadows, it respects this part here and blocks out light.

96
00:05:04,470 --> 00:05:08,180
But this is kind of the difference between a spotlight and a surface light.

97
00:05:08,190 --> 00:05:13,710
So while a spotlight shines out, light from a point a surface light shines out light from an entire

98
00:05:13,710 --> 00:05:14,880
surface of a part.

99
00:05:14,910 --> 00:05:20,390
Now, the cool thing with point lights and spotlights is that you can put them in attachments.

100
00:05:20,400 --> 00:05:25,320
So this attachment here that belongs to this part, I can put like a spotlight in here.

101
00:05:27,520 --> 00:05:28,810
And put it in the bottom.

102
00:05:29,980 --> 00:05:34,570
And now I can independently change the location of my spotlight.

103
00:05:34,570 --> 00:05:39,730
So instead of it being directly in the center of my part, I can use this attachment and kind of switch

104
00:05:39,730 --> 00:05:42,100
up wherever I want my spotlight to be.

105
00:05:42,520 --> 00:05:44,530
So here's my spotlight moving around.

106
00:05:47,390 --> 00:05:49,280
Or I can do it with a point light.

107
00:05:49,280 --> 00:05:51,020
So if I put a point light in here.

108
00:05:51,780 --> 00:05:54,840
Now I can change around where my point light is located.

109
00:05:54,840 --> 00:05:57,660
And remember, this light still belongs to this part here.

110
00:05:57,660 --> 00:06:02,700
So if I move this part around, you can see still belongs to the part, but the attachment just gives

111
00:06:02,700 --> 00:06:06,870
you a little bit more freedom on where you want to put your light in your game.
