表示在 2D 游戏中使用的精灵对象。
Sprites are 2D graphic objects used for characters, props, projectiles and other elements of 2D gameplay. The graphics are obtained from bitmap images - Texture2D. The Sprite class primarily identifies the section of the image that should be used for a specific Sprite. This information can then be used by a SpriteRenderer component on a GameObject to actually display the graphic.

| associatedAlphaSplitTexture | Returns the Texture that contains the alpha channel from the source Texture. Unity generates this Texture under the hood for Sprites that have alpha in the source, and need to be compressed using techniques like ETC1.Returns NULL if there is no associated alpha Texture for the source Sprite. This is the case if the Sprite has not been setup to use ETC1 compression. |
| border | Returns the border sizes of the Sprite. |
| bounds | 精灵的 Bounds，由精灵的中心和范围（采用世界空间单位）指定。 |
| packed | 如果该精灵打包在图集中，则返回 true。 |
| packingMode | 如果精灵已打包（请参阅 Sprite.packed），则返回其 SpritePackingMode。 |
| packingRotation | 如果精灵已打包（请参阅 Sprite.packed），则返回其 SpritePackingRotation。 |
| pivot | 精灵的中心点在原始纹理的 Rect 中的位置（以像素为单位指定）。 |
| pixelsPerUnit | The number of pixels in the Sprite that correspond to one unit in world space. (Read Only) |
| rect | 精灵在原始纹理中的位置（以像素为单位指定）。 |
| spriteAtlasTextureScale | The Variant scale of Texture used by the Sprite. This is useful to check when a Variant SpriteAtlas is being used by Sprites. |
| texture | Get the reference to the used Texture. If packed this will point to the atlas, if not packed will point to the source Sprite. |
| textureRect | Get the rectangle this Sprite uses on its Texture. Raises an exception if this Sprite is tightly packed in an atlas. |
| textureRectOffset | Gets the offset of the rectangle this Sprite uses on its Texture to the original Sprite bounds. If Sprite mesh type is FullRect, offset is zero. |
| triangles | Returns a copy of the array containing Sprite mesh triangles. |
| uv | The base Texture coordinates of the Sprite mesh. |
| vertices | Returns a copy of the array containing Sprite mesh vertex positions. |
| AddScriptableObject | Adds a ScriptableObject reference to the sprite. |
| GetPhysicsShape | 按索引从精灵获取物理形状。 |
| GetPhysicsShapeCount | 精灵的物理形状数量。 |
| GetPhysicsShapePointCount | Retrieves the number of points in the selected physics shape for the sprite. |
| GetScriptableObjects | Retrieves an array of ScriptableObject referenced by the sprite. |
| GetScriptableObjectsCount | Gets the number of ScriptableObject that the sprite references. |
| GetSecondaryTextureCount | Gets the number of Secondary Textures that the Sprite is using. |
| GetSecondaryTextures | Retrieves an array of SecondarySpriteTexture used by the Sprite. |
| OverrideGeometry | 设置新的精灵几何形状。 |
| OverridePhysicsShape | 设置新的精灵物理形状。 |
| RemoveScriptableObjectAt | Removes the ScriptableObject reference from the sprite. |
| SetScriptableObjectAt | Replace the ScriptableObject reference from the sprite. |
| Create | 创建新的 Sprite 对象。 |
| GetInstanceID | Gets the instance ID of the object. |
| ToString | 返回对象的名称。 |
| Destroy | 移除 GameObject、组件或资源。 |
| DestroyImmediate | 立即销毁对象 /obj/。强烈建议您改用 Destroy。 |
| DontDestroyOnLoad | 在加载新的 Scene 时，请勿销毁 Object。 |
| FindAnyObjectByType | Retrieves any active loaded object of Type type. |
| FindFirstObjectByType | Retrieves the first active loaded object of Type type. |
| FindObjectsByType | Retrieves a list of all loaded objects of Type type. |
| Instantiate | 克隆 original 对象并返回克隆对象。 |
| bool | 该对象是否存在？ |
| operator != | 比较两个对象是否引用不同的对象。 |
| operator == | 比较两个对象引用，判断它们是否引用同一个对象。 |
