FlixelBlendMode

enum

org.flixelgdx.util.FlixelBlendMode

public final enum FlixelBlendMode

Enum for different FlixelSprite blend modes.

Using any blend mode other than FlixelBlendMode.NORMAL will send an extra flush to the GPU, so it's a good idea to be mindful of what sprites to apply blending to.

Layering also matters. Some blend types are usually affected when something is above or below it, so keep that in mind when using this.

Fields

NORMAL

public static final FlixelBlendMode NORMAL

Normal drawing, no special blending. The default for every sprite.

ADD

public static final FlixelBlendMode ADD

Adds a sprite's color to whatever is already drawn underneath, brightening it. Good for glows, fire, and light effects.

MULTIPLY

public static final FlixelBlendMode MULTIPLY

Multiplies a sprite's color with what's underneath, darkening it. Good for shadows and tinting.

SCREEN

public static final FlixelBlendMode SCREEN

Lightens what's underneath based on a sprite's color, the opposite of FlixelBlendMode.MULTIPLY. Good for lighting without fully blowing out to white like FlixelBlendMode.ADD can.

SUBTRACT

public static final FlixelBlendMode SUBTRACT

Subtracts a sprite's color from whatever is underneath, darkening it. Good for smoke or ink effects.

LIGHTEN

public static final FlixelBlendMode LIGHTEN

Keeps whichever is brighter: a sprite's color or what's underneath, pixel by pixel. Good for particles and highlights that shouldn't over-brighten upon overlap.

DARKEN

public static final FlixelBlendMode DARKEN

Keeps whichever is darker: a sprite's color or what's underneath, pixel by pixel. The opposite of LIGHTEN. Good for shading and vignette-style overlays.
