<brief_description>
|
|
A color interpolator resource which can be used to generate colors between user-defined color points.
|
|
</brief_description>
|
|
<description>
|
|
Given a set of colors, this resource will interpolate them in order. This means that if you have color 1, color 2 and color 3, the gradient will interpolate from color 1 to color 2 and from color 2 to color 3. The gradient will initially have 2 colors (black and white), one (black) at gradient lower offset 0 and the other (white) at the gradient higher offset 1.
|
|
See also [Curve] which supports more complex easing methods, but does not support colors.

Gradient's colors returned as a [PackedColorArray].

The color space used to interpolate between points of the gradient. It does not affect the returned colors, which will always be in sRGB space. See [enum ColorSpace] for available modes.
