Struct TextureAtlas

pub struct TextureAtlas {
    pub layout: Handle<TextureAtlasLayout>,
    pub index: usize,
}

An index into a TextureAtlasLayout, which corresponds to a specific section of a texture.

It stores a handle to TextureAtlasLayout and the index of the current section of the atlas. The texture atlas contains various sections of a given texture, allowing users to have a single image file for either sprite animation or global mapping. You can change the texture index of the atlas to animate the sprite or display only a section of the texture for efficient rendering of related game objects.

Check the following examples for usage:

• animated sprite sheet example
• sprite animation event example
• texture atlas example

Fields

layout: Handle<TextureAtlasLayout>

Texture atlas layout handle

index: usize

Texture atlas section index
