Struct Sprite 

pub struct Sprite {
    pub image: Handle<Image>,
    pub texture_atlas: Option<TextureAtlas>,
    pub color: Color,
    pub flip_x: bool,
    pub flip_y: bool,
    pub custom_size: Option<Vec2>,
    pub rect: Option<Rect>,
    pub image_mode: SpriteImageMode,
}

Describes a sprite to be rendered to a 2D camera

Fields

image: Handle<Image>

The image used to render the sprite

texture_atlas: Option<TextureAtlas>

The (optional) texture atlas used to render the sprite

color: Color

The sprite’s color tint

flip_x: bool

Flip the sprite along the X axis

flip_y: bool

Flip the sprite along the Y axis

custom_size: Option<Vec2>

An optional custom size for the sprite that will be used when rendering, instead of the size of the sprite’s image

rect: Option<Rect>

An optional rectangle representing the region of the sprite’s image to render, instead of rendering the full image. This is an easy one-off alternative to using a TextureAtlas.

When used with a TextureAtlas, the rect is offset by the atlas’s minimal (top-left) corner position.

image_mode: SpriteImageMode

How the sprite’s image will be scaled.

Implementations
