TextureAtlas

Struct TextureAtlas 

Source
pub struct TextureAtlas {
    pub width: u32,
    pub height: u32,
    /* private fields */
}
Expand description

纹理图集

将一张大纹理划分为多个命名的矩形子区域。

§示例

use anvilkit_render::renderer::sprite::{TextureAtlas, AtlasRect};

let mut atlas = TextureAtlas::new(512, 512);
atlas.add_rect("player_idle", AtlasRect::new(0.0, 0.0, 0.25, 0.5));
assert!(atlas.get_rect("player_idle").is_some());
assert_eq!(atlas.rect_count(), 1);

Fields§

§width: u32

图集纹理宽度(像素)

§height: u32

图集纹理高度(像素)

Source§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
