创建新的 Sprite 对象。
Sprite.Create creates a new Sprite which can be used in game applications.
A texture needs to be loaded and assigned to Create in order to control how the
new Sprite will look. In the script example below a new Sprite is displayed
when the button is pressed. The new sprite is created in Start.
The second argument rect defines the sub-texture used. The rect argument is defined in
pixels of the texture. A Rect(50.0f, 10.0f, 200.0f, 140.0f) would create a left to right
range from 50.0f to 50.0f + 200.0f = 250.0f. The bottom to top range would be 10.0f to
10.0f + 140.0f = 150.0f.
The third argument pivot determines what becomes the center
of the Sprite. This is a Vector2 relative to the rect where Vector2(0.0f, 0.0f) is the bottom
left and Vector2(1.0f, 1.0f) is the top right. The pixelsPerUnit value controls
the size of the sprite. Reducing this below 100 pixels per world increases the size of
the sprite. The extrude value defines the number of pixels which surround the Sprite.
This is useful if the Sprite is included in an atlas. meshType selects whether
FullRect or Tight is used. Finally border determines the slicing of the Sprite and
is usually used to define Sprite tiling behaviour. The values are in pixel units.
