Struct bevy::math::IRect

#[repr(C)]
pub struct IRect { pub min: IVec2, pub max: IVec2, }
Expand description

A rectangle defined by two opposite corners.

The rectangle is axis aligned, and defined by its minimum and maximum coordinates, stored in IRect::min and IRect::max, respectively. The minimum/maximum invariant must be upheld by the user when directly assigning the fields, otherwise some methods produce invalid results. It is generally recommended to use one of the constructor methods instead, which will ensure this invariant is met, unless you already have the minimum and maximum corners.

Fields§

§min: IVec2

The minimum corner point of the rect.

§max: IVec2

The maximum corner point of the rect.

Implementations§

§

impl IRect

pub fn new(x0: i32, y0: i32, x1: i32, y1: i32) -> IRect

Create a new rectangle from two corner points.

The two points do not need to be the minimum and/or maximum corners. They only need to be two opposite corners.

Examples
let r = IRect::new(0, 4, 10, 6); // w=10 h=2
let r = IRect::new(2, 3, 5, -1); // w=3 h=4

pub fn from_corners(p0: IVec2, p1: IVec2) -> IRect

Create a new rectangle from two corner points.

The two points do not need to be the minimum and/or maximum corners. They only need to be two opposite corners.

Examples
// Unit rect from [0,0] to [1,1]
let r = IRect::from_corners(IVec2::ZERO, IVec2::ONE); // w=1 h=1
// Same; the points do not need to be ordered
let r = IRect::from_corners(IVec2::ONE, IVec2::ZERO); // w=1 h=1

pub fn from_center_size(origin: IVec2, size: IVec2) -> IRect

Create a new rectangle from its center and size.

Rounding Behaviour

If the size contains odd numbers they will be rounded down to the nearest whole number.

Panics

This method panics if any of the components of the size is negative.

Examples
let r = IRect::from_center_size(IVec2::ZERO, IVec2::new(3, 2)); // w=2 h=2
assert_eq!(r.min, IVec2::splat(-1));
assert_eq!(r.max, IVec2::splat(1));

pub fn from_center_half_size(origin: IVec2, half_size: IVec2) -> IRect

Create a new rectangle from its center and half-size.

Panics

This method panics if any of the components of the half-size is negative.

Examples
let r = IRect::from_center_half_size(IVec2::ZERO, IVec2::ONE); // w=2 h=2
assert_eq!(r.min, IVec2::splat(-1));
assert_eq!(r.max, IVec2::splat(1));

pub fn is_empty(&self) -> bool

Check if the rectangle is empty.

Examples
let r = IRect::from_corners(IVec2::ZERO, IVec2::new(0, 1)); // w=0 h=1
assert!(r.is_empty());

pub fn width(&self) -> i32

Rectangle width (max.x - min.x).

Examples
let r = IRect::new(0, 0, 5, 1); // w=5 h=1
assert_eq!(r.width(), 5);

pub fn height(&self) -> i32

Rectangle height (max.y - min.y).

Examples
let r = IRect::new(0, 0, 5, 1); // w=5 h=1
assert_eq!(r.height(), 1);

pub fn size(&self) -> IVec2

Rectangle size.

Examples
let r = IRect::new(0, 0, 5, 1); // w=5 h=1
assert_eq!(r.size(), IVec2::new(5, 1));

pub fn half_size(&self) -> IVec2

Rectangle half-size.

Rounding Behaviour

If the full size contains odd numbers they will be rounded down to the nearest whole number when calculating the half size.

Examples
let r = IRect::new(0, 0, 4, 3); // w=4 h=3
assert_eq!(r.half_size(), IVec2::new(2, 1));

pub fn center(&self) -> IVec2

The center point of the rectangle.

Rounding Behaviour

If the (min + max) contains odd numbers they will be rounded down to the nearest whole number when calculating the center.

Examples
let r = IRect::new(0, 0, 5, 2); // w=5 h=2
assert_eq!(r.center(), IVec2::new(2, 1));

pub fn contains(&self, point: IVec2) -> bool

Check if a point lies within this rectangle, inclusive of its edges.

Examples
let r = IRect::new(0, 0, 5, 1); // w=5 h=1
assert!(r.contains(r.center()));
assert!(r.contains(r.min));
assert!(r.contains(r.max));

pub fn union(&self, other: IRect) -> IRect

Build a new rectangle formed of the union of this rectangle and another rectangle.

The union is the smallest rectangle enclosing both rectangles.

Examples
let r1 = IRect::new(0, 0, 5, 1); // w=5 h=1
let r2 = IRect::new(1, -1, 3, 3); // w=2 h=4
let r = r1.union(r2);
assert_eq!(r.min, IVec2::new(0, -1));
assert_eq!(r.max, IVec2::new(5, 3));

pub fn union_point(&self, other: IVec2) -> IRect

Build a new rectangle formed of the union of this rectangle and a point.

The union is the smallest rectangle enclosing both the rectangle and the point. If the point is already inside the rectangle, this method returns a copy of the rectangle.

Examples
let r = IRect::new(0, 0, 5, 1); // w=5 h=1
let u = r.union_point(IVec2::new(3, 6));
assert_eq!(u.min, IVec2::ZERO);
assert_eq!(u.max, IVec2::new(5, 6));

pub fn intersect(&self, other: IRect) -> IRect

Build a new rectangle formed of the intersection of this rectangle and another rectangle.

The intersection is the largest rectangle enclosed in both rectangles. If the intersection is empty, this method returns an empty rectangle (IRect::is_empty() returns true), but the actual values of IRect::min and IRect::max are implementation-dependent.

Examples
let r1 = IRect::new(0, 0, 5, 1); // w=5 h=1
let r2 = IRect::new(1, -1, 3, 3); // w=2 h=4
let r = r1.intersect(r2);
assert_eq!(r.min, IVec2::new(1, 0));
assert_eq!(r.max, IVec2::new(3, 1));

pub fn inset(&self, inset: i32) -> IRect

Create a new rectangle with a constant inset.

The inset is the extra border on all sides. A positive inset produces a larger rectangle, while a negative inset is allowed and produces a smaller rectangle. If the inset is negative and its absolute value is larger than the rectangle half-size, the created rectangle is empty.

Examples
let r = IRect::new(0, 0, 5, 1); // w=5 h=1
let r2 = r.inset(3); // w=11 h=7
assert_eq!(r2.min, IVec2::splat(-3));
assert_eq!(r2.max, IVec2::new(8, 4));

let r = IRect::new(0, -1, 4, 3); // w=4 h=4
let r2 = r.inset(-1); // w=2 h=2
assert_eq!(r2.min, IVec2::new(1, 0));
assert_eq!(r2.max, IVec2::new(3, 2));

pub fn as_rect(&self) -> Rect

Returns self as Rect (f32)

pub fn as_urect(&self) -> URect

Returns self as URect (u32)
