Color interpolator node. Given a set of colors, this node will interpolate them in order, meaning, that if you have color 1, color 2 and color3, the ramp will interpolate (generate the colors between two colors) from color 1 to color 2 and from color 2 to color 3. Initially the ramp will have 2 colors (black and white), one (black) at ramp lower offset 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 [i]point[/i] Returns the colors in the ramp Returns the offset of the ramp color at index [i]point[/i] Returns the offsets for the colors in this ramp Returns the number of colors in the ramp Returns the interpolated color specified by [i]offset[/i] Removes the color at the index [i]offset[/i] Sets the color of the ramp color at index [i]point[/i] Sets the colors for the specified amount of elements. Calling this function with a different number of elements than previously defined causes the ramp to resize its colors and offsets array to accommodate the new elements. Sets the offset for the ramp color at index [i]point[/i] Sets the offset for the specified amount of elements. Calling this function with a different number of elements than previously defined causes the ramp to resize its colors and offsets array to accommodate the new elements, all new colors will be black by default. Gradient's colors returned as a [PoolColorArray]. Gradient's offsets returned as a [PoolRealArray].
