Constructor Details

ColorRGBA

public ColorRGBA()

Creates a new white color (all values 1)

ColorRGBA

public ColorRGBA(int rgba)

ColorRGBA

public ColorRGBA(float r,
 float g,
 float b,
 float a)

Creates a new Vector4f with the provided values.

Parameters:

r - the red color component (0-1).

g - the green color component (0-1).

b - the blue color component (0-1).

a - the alpha (opacity) color component (0-1).

ColorRGBA

public ColorRGBA(ColorRGBA copy)

Creates a new color and copies the values from the provided color.

Parameters:

copy - the color to copy.

Method Details

set

public ColorRGBA set(ColorRGBA color)

Sets the r, g, b and a values of this color to the values of the provided color.

Parameters:

color - the ColorRGBA to copy.

Returns:

this color.

set

public ColorRGBA set(float r,
 float g,
 float b,
 float a)

Sets the r, g, b and a values of this color to the provided values.

Parameters:

r - the red color value.

g - the green color value.

b - the blue color value.

a - the alpha (opacity) color value.

Returns:

this color.

interpolateLocal

public ColorRGBA interpolateLocal(ColorRGBA color,
 float mu)

Interpolates this color to the provided final color, e.g if this color is (0, 0, 1, 1), and the final color is (1, 0.5f, 0, 1), the result (by using a mu-value of 0.5f) would be (0.5f, 0.25f, 0.5f, 1)

Parameters:

color - the color to interpolate towards.

mu - the mu value between 0.0 and 1.0 (i.e the percentage change from this color to towards the final color).

Returns:

this color containing the interpolated color values.

toVector4f
