Struct Color 

#[repr(C)]
pub struct Color {
    pub r: f32,
    pub g: f32,
    pub b: f32,
    pub a: f32,
}

A color represented by 4 floats: red, green, blue and alpha.

Fields

r: f32

Red channel value from 0.0 to 1.0.

g: f32

Green channel value from 0.0 to 1.0.

b: f32

Blue channel value from 0.0 to 1.0.

a: f32

Alpha channel value from 0.0 to 1.0.

Implementations

impl Color

pub const fn new(r: f32, g: f32, b: f32, a: f32) -> Color

Creates a new Color with the given red, green, blue, and alpha components. Values are expected to be between 0.0 and 1.0.

Example

use macroquad::prelude::*;

let pink = Color::new(1.00, 0.43, 0.76, 1.00);
assert_eq!(pink.r, 1.00);
assert_eq!(pink.g, 0.43);
assert_eq!(pink.b, 0.76);
assert_eq!(pink.a, 1.00);

Note that values outside of this range are effectively clamped, and do not generate an error or warning.

pub const fn from_rgba(r: u8, g: u8, b: u8, a: u8) -> Color

Build a color from 4 components between 0 and 255.

pub const fn from_hex(hex: u32) -> Color

Build a color from a hexadecimal u32.

Example

use macroquad::prelude::*;

let light_blue = Color::from_hex(0x3CA7D5);
assert_eq!(light_blue.r, 0.23529412);
assert_eq!(light_blue.g, 0.654902);
assert_eq!(light_blue.b, 0.8352941);
assert_eq!(light_blue.a, 1.00);

pub const fn to_vec(&self) -> Vec4

Create a vec4 of red, green, blue, and alpha components.

pub const fn from_vec(vec: Vec4) -> Color

Create a color from a vec4 of red, green, blue, and alpha components.

pub const fn with_alpha(&self, alpha: f32) -> Color

Create a copy of the current color, but with a different alpha value.

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Color

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

Formats the value using the given formatter.

impl Default for Color

fn default() -> Color

Returns the “default value” for a type.

impl From<[f32; 4]> for Color

fn from(colors: [f32; 4]) -> Color

Converts to this type from the input type.

impl From<[u8; 4]> for Color

fn from(val: [u8; 4]) -> Color

Converts to this type from the input type.

impl From<Color> for Color

fn from(c: Color) -> Self

Converts to this type from the input type.

impl From<Color> for Color

fn from(c: Color) -> Self

Converts to this type from the input type.

impl PartialEq for Color

fn eq(&self, other: &Color) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
