A color transition.

Description

This resource describes a color transition by defining a set of colored points and how to interpolate between them.

See also Curve which supports more complex easing methods, but does not support colors.

Enumerations

enum InterpolationMode: 🔗

InterpolationMode GRADIENT_INTERPOLATE_LINEAR = 0

Linear interpolation.

InterpolationMode GRADIENT_INTERPOLATE_CONSTANT = 1

Constant interpolation, color changes abruptly at each point and stays uniform between. This might cause visible aliasing when used for a gradient texture in some cases.

InterpolationMode GRADIENT_INTERPOLATE_CUBIC = 2

Cubic interpolation.

enum ColorSpace: 🔗

ColorSpace GRADIENT_COLOR_SPACE_SRGB = 0

sRGB color space.

ColorSpace GRADIENT_COLOR_SPACE_LINEAR_SRGB = 1

Linear sRGB color space.

ColorSpace GRADIENT_COLOR_SPACE_OKLAB = 2

Oklab color space. This color space provides a smooth and uniform-looking transition between colors.

Property Descriptions

PackedColorArray colors = PackedColorArray(0, 0, 0, 1, 1, 1, 1, 1) 🔗

Gradient's colors as a PackedColorArray.

Note: Setting this property updates all colors at once. To update any color individually use set_color().

Note: The returned array is copied and any changes to it will not update the original property value. See PackedColorArray for more details.

ColorSpace interpolation_color_space = 0 🔗

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.

Note: This setting has no effect when interpolation_mode is set to GRADIENT_INTERPOLATE_CONSTANT.

InterpolationMode interpolation_mode = 0 🔗

The algorithm used to interpolate between points of the gradient.

PackedFloat32Array offsets = PackedFloat32Array(0, 1) 🔗

Gradient's offsets as a PackedFloat32Array.

Note: Setting this property updates all offsets at once. To update any offset individually use set_offset().

Note: The returned array is copied and any changes to it will not update the original property value. See PackedFloat32Array for more details.

Method Descriptions

void add_point(offset: float, color: Color) 🔗

Adds the specified color to the gradient, with the specified offset.

Color get_color(point: int) 🔗

Returns the color of the gradient color at index point.

float get_offset(point: int) 🔗

Returns the offset of the gradient color at index point.

int get_point_count() const 🔗

Returns the number of colors in the gradient.

void remove_point(point: int) 🔗

Removes the color at index point.

void reverse() 🔗

Reverses/mirrors the gradient.

Note: This method mirrors all points around the middle of the gradient, which may produce unexpected results when interpolation_mode is set to GRADIENT_INTERPOLATE_CONSTANT.

Color sample(offset: float) 🔗

Returns the interpolated color specified by offset. offset should be between 0.0 and 1.0 (inclusive). Using a value lower than 0.0 will return the same color as 0.0, and using a value higher than 1.0 will return the same color as 1.0. If your input value is not within this range, consider using @GlobalScope.remap() on the input value with output values set to 0.0 and 1.0.

void set_color(point: int, color: Color) 🔗

Sets the color of the gradient color at index point.

void set_offset(point: int, offset: float) 🔗

Sets the offset for the gradient color at index point.
