0:00:01.160,0:00:03.819
The sprite renderer component displays images

0:00:03.819,0:00:06.383
that have been imported as the sprite type

0:00:06.383,0:00:09.412
for use in both 2D and 3D scenes.

0:00:10.112,0:00:12.140
The primary property of the sprite

0:00:12.140,0:00:14.140
renderer is sprite.

0:00:15.648,0:00:18.390
This is a reference to the sprite to render.

0:00:20.216,0:00:22.649
For more information on the sprite import type

0:00:22.649,0:00:25.136
please see the information linked below.

0:00:26.820,0:00:29.805
Colour is the vertex colour of the rendered sprite

0:00:29.805,0:00:31.805
and can be used to tint or recolour

0:00:31.805,0:00:33.266
the sprite image.

0:00:35.009,0:00:37.009
Colour can also be used to fade the

0:00:37.009,0:00:39.009
sprite's opacity by changing the value

0:00:39.009,0:00:41.009
of the colour's alpha channel.

0:00:42.738,0:00:44.738
The sprite's colour property is independent

0:00:44.738,0:00:47.866
of the sprite's material, so changing the colour

0:00:47.866,0:00:49.866
property on a sprite will only effect

0:00:49.866,0:00:51.866
that particular game object.

0:00:53.678,0:00:55.678
Material is a reference to the material

0:00:55.678,0:00:57.915
used to render the sprite.

0:00:59.034,0:01:01.546
By default a new sprite renderer component

0:01:01.546,0:01:04.831
will have the material sprite's default assigned.

0:01:06.049,0:01:08.757
When using this default material the sprite will not

0:01:08.757,0:01:11.299
be effected by any lighting in the scene.

0:01:12.030,0:01:14.030
The sprite renderer will simply render the

0:01:14.030,0:01:16.414
original sprite at full brightness.

0:01:17.234,0:01:19.798
In many cases lighting is not necessary

0:01:19.798,0:01:21.798
when creating a 2D game.

0:01:22.381,0:01:24.381
To use lights with a sprite renderer

0:01:24.381,0:01:26.381
a material with a shader that responds

0:01:26.381,0:01:28.381
to lighting must be selected.

0:01:28.922,0:01:32.577
Sprites Diffuse is optimised for use with sprites,

0:01:32.577,0:01:35.071
but many other shaders can be used.

0:01:40.353,0:01:43.025
Due to the nature of shaders, and the sprite renderer,

0:01:43.025,0:01:46.203
some shaders are incompatible with the sprite renderer.

0:01:47.905,0:01:50.501
Sprites use standard Unity materials,

0:01:50.501,0:01:52.501
however, the sprite renderer handles

0:01:52.501,0:01:55.537
materials differently than the mesh renderer.

0:01:56.465,0:01:58.465
The main difference is that the material's

0:01:58.465,0:02:00.465
texture property is not needed.

0:02:01.393,0:02:03.780
The sprite renderer will use the shader,

0:02:03.780,0:02:07.078
colour and other properties from a compatible material

0:02:07.078,0:02:09.078
but not the texture property.

0:02:11.028,0:02:14.396
When using a material that has a sprite shader

0:02:15.117,0:02:17.766
the texture property is unavailable.

0:02:20.462,0:02:22.930
If the attached material has a tint colour

0:02:22.930,0:02:25.807
it will be combined with the sprite's colour property.

0:02:33.102,0:02:37.206
It is important to note that lighting and shadow.

0:02:37.206,0:02:40.169
So when using lights and more complex shaders

0:02:40.169,0:02:44.053
it is best to balance the lighting with the performance of the scene.

0:02:44.912,0:02:47.617

0:02:52.783,0:02:54.783
Sorting Layer and Order In Layer are

0:02:54.783,0:02:56.783
the systems used to define the order

0:02:56.783,0:02:58.783
in which sprites are drawn.

0:03:00.443,0:03:02.568
All sprite renderers are placed on a default

0:03:02.568,0:03:04.568
sorting layer when they are created.

0:03:05.800,0:03:08.171
Sprites are rendered by the sprite render

0:03:08.171,0:03:10.171
in the following order of priority.

0:03:11.127,0:03:14.391
The order of the sorting layer, containing the sprite,

0:03:16.106,0:03:18.106
the order in layer value for the sprite

0:03:18.106,0:03:20.106
within that sorting layer

0:03:22.277,0:03:24.277
and finally the sprite's transform position

0:03:24.277,0:03:26.875
Z compared to the other sprites being rendered

0:03:26.875,0:03:28.875
and the camera rendering them.

0:03:29.776,0:03:32.549
In the case of sorting layers and order-in-layer

0:03:32.549,0:03:34.549
items with lower values will be

0:03:34.549,0:03:36.731
behind those with higher values.

0:03:37.477,0:03:40.499
