Gradient

Inherits: Resource < Reference < 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:

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.


Property Descriptions

PoolColorArray colors = PoolColorArray( 0, 0, 0, 1, 1, 1, 1, 1 )

Gradient's colors returned as a PoolColorArray.


InterpolationMode interpolation_mode = 0

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


PoolRealArray offsets = PoolRealArray( 0, 1 )

Gradient's offsets returned as a PoolRealArray.


Method Descriptions

void add_point ( float offset, Color color )

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


Color get_color ( int point )

Returns the color of the ramp color at index point.


float get_offset ( int point )

Returns the offset of the ramp color at index point.


int get_point_count ( ) const

Returns the number of colors in the ramp.


Color interpolate ( float offset )

Returns the interpolated color specified by offset.


void remove_point ( int point )

Removes the color at the index point.


void set_color ( int point, Color color )

Sets the color of the ramp color at index point.


void set_offset ( int point, float offset )

Sets the offset for the ramp color at index point.
