If the source color is darker than 0.5, the backdrop is darkened, as if it were multiplied; this is useful for adding shadows to a scene.

The degree of lightening or darkening is proportional to the difference between the source color and 0.5; if it is equal to 0.5, the backdrop is unchanged.

Painting with pure black or white produces pure black or white. The effect is similar to shining a harsh spotlight on the backdrop.

<static> blendSoftLight(a, b) → {integer}

Darkens or lightens the colors, depending on the source color value.

If the source color is lighter than 0.5, the backdrop is lightened, as if it were dodged; this is useful for adding highlights to a scene.

If the source color is darker than 0.5, the backdrop is darkened, as if it were burned in. The degree of lightening or darkening is proportional to the difference between the source color and 0.5; if it is equal to 0.5, the backdrop is unchanged.

Painting with pure black or white produces a distinctly darker or lighter area, but does not result in pure black or white. The effect is similar to shining a diffused spotlight on the backdrop.

Parameters
Name Type Description
a integer

The source color to blend, in the range 1 to 255.

b integer

Source code: utils/Color.js (Line 1053)

<static> blendVividLight(a, b) → {integer}

This blend mode combines Color Dodge and Color Burn (rescaled so that neutral colors become middle gray). Dodge applies when values in the top layer are lighter than middle gray, and burn to darker values. The middle gray is the neutral color. When color is lighter than this, this effectively moves the white point of the bottom layer down by twice the difference; when it is darker, the black point is moved up by twice the difference. The perceived contrast increases.

Parameters

The source color to blend, in the range 1 to 255.

b integer

Parameters
Name Type Argument Description
r number

The red color component, in the range 0 - 255.

g number

The green color component, in the range 0 - 255.

b number

The blue color component, in the range 0 - 255.

out object <optional>

An object into which 3 properties will be created, h, s and l. If not provided a new object will be created.

Returns
object -

An object with the hue, saturation and lightness values set in the h, s and l properties.

<static> RGBtoString(r, g, b, a, prefix) → {string}

Converts the given color values into a string. If prefix was '#' it will be in the format #RRGGBB otherwise 0xAARRGGBB.

Parameters
Name Type Argument Default Description
r number

g number

The green color component, in the range 0 - 255.

b number

The blue color component, in the range 0 - 255.

a number <optional>
255

The alpha color component, in the range 0 - 255.

prefix string <optional>
'#'

The prefix used in the return string. If '#' it will return #RRGGBB, else 0xAARRGGBB.

Returns
string -

g number

The green color component, in the range 0 - 255.

<static> unpackPixel(rgba, out, hsl, hsv) → {object}

Unpacks the r, g, b, a components into the specified color object, or a new object, for use with Int32Array. If little endian, then ABGR order is used when unpacking, otherwise, RGBA order is used. The resulting color object has the r, g, b, a properties which are unrelated to endianness.

Note that the integer is assumed to be packed in the correct endianness. On little-endian the format is 0xAABBGGRR and on big-endian the format is 0xRRGGBBAA. If you want a endian-independent method, use fromRGBA(rgba) and toRGBA(r, g, b, a).

Parameters
Name Type Argument Default Description
rgba number

The integer, packed in endian order by packPixel.

out object <optional>

An object into which 3 properties will be created: r, g and b. If not provided a new object will be created.

hsl boolean <optional>
false

Also convert the rgb values into hsl?

hsv boolean <optional>
false

Also convert the rgb values into hsv?

Returns
object -

An object with the red, green and blue values set in the r, g and b properties.

<static> updateColor(out) → {number}

Takes a color object and updates the rgba, color and color32 properties.

Parameters
Name Type Description
out object

The color object to update.

Returns
number -

A native color value integer (format: 0xAARRGGBB).

Source code: utils/Color.js (Line 448)

<static> valueToColor(value, out) → {object}

Converts a value - a "hex" string, a "CSS 'web' string", or a number - into red, green, blue, and alpha components.

The value can be a string (see hexToColor and webToColor for the supported formats) or a packed integer (see getRGB).

An alpha channel is not supported when specifying a hex string.

Parameters
Name Type Argument Description
value string | number

The color expressed as a recognized string format or a packed integer.

out object <optional>

The object to use for the output. If not provided a new object will be created.

Returns
object -

The (out) object with the red, green, blue, and alpha values set as the r/g/b/a properties.

Source code: utils/Color.js (Line 624)

<static> webToColor(web, out) → {object}

Converts a CSS 'web' string into a Phaser Color object.

The web string can be in the format 'rgb(r,g,b)' or 'rgba(r,g,b,a)' where r/g/b are in the range [0..255] and a is in the range [0..1].

Parameters
Name Type Argument Description
web string

The color string in CSS 'web' format.

out object <optional>

An object into which 4 properties will be created: r, g, b and a. If not provided a new object will be created.

Returns
object -

An object with the red, green, blue and alpha values set in the r, g, b and a properties.
