Struct moon_engine::texture::SubTexture

pub struct SubTexture { /* private fields */ }

A SubTexture is a part of a full Texture.

It stores the UV co-ordinates of the part of the Texture it occupies.

Implementations

impl SubTexture

pub fn new(texture: Rc<Texture>) -> Self

Create a new SubTexture with the full UV co-ordinates.

pub fn new_with_coords(texture: Rc<Texture>, uv: Color32) -> Self

Create a new SubTexture with the given UV co-ordinates.

pub fn get_uv_coords(&self) -> [[f32; 2]; 4]

Get the UV co-ordinates as an array of four two-component f32.

pub fn create_tiles_from_spritesheet(
    texture: Rc<Texture>,
    horizontal_cells: u32,
    vertical_cells: u32
) -> Vec<SubTexture>

Create a Vec of SubTextures from a sprite sheet.

Uses the number of cells horizontally and vertically to devide the cells.

Trait Implementations

impl Bind for SubTexture

fn bind(&self, gl: &GL)

Binds a struct implementing the Bind trait. This is up to the implementation to decide.

fn unbind(&self, gl: &GL)

Optionally unbinds a struct implementing the Bind trait. This effectively resets the WebGL state.

impl Clone for SubTexture

fn clone(&self) -> SubTexture

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SubTexture

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SubTexture

fn default() -> Self

Returns the “default value” for a type.
