[][src]Struct tetra::graphics::Rectangle

pub struct Rectangle {
    pub x: f32,
    pub y: f32,
    pub width: f32,
    pub height: f32,
}

A rectangle of f32s.

Fields

x: f32

The X co-ordinate of the rectangle.

y: f32

The Y co-ordinate of the rectangle.

width: f32

The width of the rectangle.

height: f32

The height of the rectangle.

Methods

impl Rectangle[src]

pub fn new(x: f32, y: f32, width: f32, height: f32) -> Rectangle[src]

Creates a new Rectangle.

pub fn row(
    x: f32,
    y: f32,
    width: f32,
    height: f32
) -> impl Iterator<Item = Rectangle>
[src]

Returns an infinite iterator of horizontally adjecent rectangles, starting at the specified point and increasing along the X axis.

This can be useful when slicing spritesheets.

Examples

let rects: Vec<Rectangle> = Rectangle::row(0.0, 0.0, 16.0, 16.0).take(3).collect();

assert_eq!(Rectangle::new(0.0, 0.0, 16.0, 16.0), rects[0]);
assert_eq!(Rectangle::new(16.0, 0.0, 16.0, 16.0), rects[1]);
assert_eq!(Rectangle::new(32.0, 0.0, 16.0, 16.0), rects[2]);

pub fn column(
    x: f32,
    y: f32,
    width: f32,
    height: f32
) -> impl Iterator<Item = Rectangle>
[src]

Returns an infinite iterator of vertically adjecent rectangles, starting at the specified point and increasing along the Y axis.

This can be useful when slicing spritesheets.

Examples

let rects: Vec<Rectangle> = Rectangle::column(0.0, 0.0, 16.0, 16.0).take(3).collect();

assert_eq!(Rectangle::new(0.0, 0.0, 16.0, 16.0), rects[0]);
assert_eq!(Rectangle::new(0.0, 16.0, 16.0, 16.0), rects[1]);
assert_eq!(Rectangle::new(0.0, 32.0, 16.0, 16.0), rects[2]);
