A color interpolator resource which can be used to generate colors between user-defined color points. 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 ramp will interpolate from color 1 to color 2 and from color 2 to color 3. The ramp will initially have 2 colors (black and white), one (black) at ramp lower offset 0 and the other (white) at the ramp higher offset 1. Adds the specified color to the end of the ramp, with the specified offset. Returns the color of the ramp color at index [code]point[/code]. Returns the offset of the ramp color at index [code]point[/code]. Returns the number of colors in the ramp. Returns the interpolated color specified by [code]offset[/code]. Removes the color at the index [code]point[/code]. Sets the color of the ramp color at index [code]point[/code]. Sets the offset for the ramp color at index [code]point[/code]. Gradient's colors returned as a [PoolColorArray]. Gradient's offsets returned as a [PoolRealArray].
