Gradient

Inherits: Resource < RefCounted < Object

A color interpolator resource which can be used to generate colors between user-defined color points.

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.

Enumerations

enum InterpolationMode:

  • GRADIENT_INTERPOLATE_LINEAR = 0 --- Linear interpolation.

  • 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.

  • GRADIENT_INTERPOLATE_CUBIC = 2 --- Cubic interpolation.

Property Descriptions

Default

PackedColorArray(0, 0, 0, 1, 1, 1, 1, 1)

Setter

set_colors(value)

Getter

get_colors()

Gradient's colors returned as a PackedColorArray.


Default

0

Setter

set_interpolation_mode(value)

Getter

get_interpolation_mode()

Defines how the colors between points of the gradient are interpolated. See InterpolationMode for available modes.


Default

PackedFloat32Array(0, 1)

Setter

set_offsets(value)

Getter

get_offsets()

Gradient's offsets returned as a PackedFloat32Array.

Method Descriptions

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


Returns the color of the gradient color at index point.


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 ( int point )

Removes the color at the index point.


  • void reverse ( )

Reverses/mirrors the gradient.


Returns the interpolated color specified by offset.


  • void set_color ( int point, Color color )

Sets the color of the gradient color at index point.


  • void set_offset ( int point, float offset )

Sets the offset for the gradient color at index point.
