1
00:00:01,160 --> 00:00:03,819
The sprite renderer component displays images

2
00:00:03,819 --> 00:00:06,383
that have been imported as the sprite type

3
00:00:06,383 --> 00:00:09,412
for use in both 2D and 3D scenes.

4
00:00:10,112 --> 00:00:12,140
The primary property of the sprite

5
00:00:12,140 --> 00:00:14,140
renderer is sprite.

6
00:00:15,648 --> 00:00:18,390
This is a reference to the sprite to render.

7
00:00:20,216 --> 00:00:22,649
For more information on the sprite import type

8
00:00:22,649 --> 00:00:25,136
please see the information linked below.

9
00:00:26,820 --> 00:00:29,805
Colour is the vertex colour of the rendered sprite

10
00:00:29,805 --> 00:00:31,805
and can be used to tint or recolour

11
00:00:31,805 --> 00:00:33,266
the sprite image.

12
00:00:35,009 --> 00:00:37,009
Colour can also be used to fade the

13
00:00:37,009 --> 00:00:39,009
sprite's opacity by changing the value

14
00:00:39,009 --> 00:00:41,009
of the colour's alpha channel.

15
00:00:42,738 --> 00:00:44,738
The sprite's colour property is independent

16
00:00:44,738 --> 00:00:47,866
of the sprite's material, so changing the colour

17
00:00:47,866 --> 00:00:49,866
property on a sprite will only effect

18
00:00:49,866 --> 00:00:51,866
that particular game object.

19
00:00:53,678 --> 00:00:55,678
Material is a reference to the material

20
00:00:55,678 --> 00:00:57,915
used to render the sprite.

21
00:00:59,034 --> 00:01:01,546
By default a new sprite renderer component

22
00:01:01,546 --> 00:01:04,831
will have the material sprite's default assigned.

23
00:01:06,049 --> 00:01:08,757
When using this default material the sprite will not

24
00:01:08,757 --> 00:01:11,299
be effected by any lighting in the scene.

25
00:01:12,030 --> 00:01:14,030
The sprite renderer will simply render the

26
00:01:14,030 --> 00:01:16,414
original sprite at full brightness.

27
00:01:17,234 --> 00:01:19,798
In many cases lighting is not necessary

28
00:01:19,798 --> 00:01:21,798
when creating a 2D game.

29
00:01:22,381 --> 00:01:24,381
To use lights with a sprite renderer

30
00:01:24,381 --> 00:01:26,381
a material with a shader that responds

31
00:01:26,381 --> 00:01:28,381
to lighting must be selected.

32
00:01:28,922 --> 00:01:32,577
Sprites Diffuse is optimised for use with sprites,

33
00:01:32,577 --> 00:01:35,071
but many other shaders can be used.

34
00:01:40,353 --> 00:01:43,025
Due to the nature of shaders, and the sprite renderer,

35
00:01:43,025 --> 00:01:46,203
some shaders are incompatible with the sprite renderer.

36
00:01:47,905 --> 00:01:50,501
Sprites use standard Unity materials,

37
00:01:50,501 --> 00:01:52,501
however, the sprite renderer handles

38
00:01:52,501 --> 00:01:55,537
materials differently than the mesh renderer.

39
00:01:56,465 --> 00:01:58,465
The main difference is that the material's

40
00:01:58,465 --> 00:02:00,465
texture property is not needed.

41
00:02:01,393 --> 00:02:03,780
The sprite renderer will use the shader,

42
00:02:03,780 --> 00:02:07,078
colour and other properties from a compatible material

43
00:02:07,078 --> 00:02:09,078
but not the texture property.

44
00:02:11,028 --> 00:02:14,396
When using a material that has a sprite shader

45
00:02:15,117 --> 00:02:17,766
the texture property is unavailable.

46
00:02:20,462 --> 00:02:22,930
If the attached material has a tint colour

47
00:02:22,930 --> 00:02:25,807
it will be combined with the sprite's colour property.

48
00:02:33,102 --> 00:02:37,206
It is important to note that lighting and shadow.

49
00:02:37,206 --> 00:02:40,169
So when using lights and more complex shaders

50
00:02:40,169 --> 00:02:44,053
it is best to balance the lighting with the performance of the scene.

51
00:02:44,912 --> 00:02:47,617
For more information on materials and shaders,

52
00:02:47,617 --> 00:02:50,107
please see the information linked below.

53
00:02:52,783 --> 00:02:54,783
Sorting Layer and Order In Layer are

54
00:02:54,783 --> 00:02:56,783
the systems used to define the order

55
00:02:56,783 --> 00:02:58,783
in which sprites are drawn.

56
00:03:00,443 --> 00:03:02,568
All sprite renderers are placed on a default

57
00:03:02,568 --> 00:03:04,568
sorting layer when they are created.

58
00:03:05,800 --> 00:03:08,171
Sprites are rendered by the sprite render

59
00:03:08,171 --> 00:03:10,171
in the following order of priority.

60
00:03:11,127 --> 00:03:14,391
The order of the sorting layer, containing the sprite,

61
00:03:16,106 --> 00:03:18,106
the order in layer value for the sprite

62
00:03:18,106 --> 00:03:20,106
within that sorting layer

63
00:03:22,277 --> 00:03:24,277
and finally the sprite's transform position

64
00:03:24,277 --> 00:03:26,875
Z compared to the other sprites being rendered

65
00:03:26,875 --> 00:03:28,875
and the camera rendering them.

66
00:03:29,776 --> 00:03:32,549
In the case of sorting layers and order-in-layer

67
00:03:32,549 --> 00:03:34,549
items with lower values will be

68
00:03:34,549 --> 00:03:36,731
behind those with higher values.

69
00:03:37,477 --> 00:03:40,499
