Simple sprite: As its name suggests, it is simply an image displayed on screen
Sliced sprite: In this, the image is sliced in nine parts and it is resizable without stretching corners
Tiled sprite: In this, the tiling pattern is repeatable indefinitely
Let's start with the Simple sprites.
It is time to create two sprites, Bomb and Time, which will illustrate our powers. First, we need to create the sprites and add them to our Game atlas. They will look as shown in the following screenshot:
You may either create them yourself, or download the
Assets.zip file from http://goo.gl/bZu4mF.
If you wish to create your own sprites, a size of 128 x 128 will be enough. You can save them either as
.png to support transparency, or as
.psd files—they will be converted to the correct format when they will be imported in the Unity project.
