public class DrawableSpaceLayer extends java.lang.Object implements SpaceLayer
A DrawableSpaceLayer is a type of SpaceLayer that displays a Drawable, optionally repeated horizontally and/or vertically across the rendering region. It can also be configured to shift its Drawable relative to the position of the camera to simulate parallax.

public DrawableSpaceLayer(Drawable drawable, int repeatX, int repeatY, long parallaxX, long parallaxY, long parallaxOriginX, long parallaxOriginY)
drawable - The Drawable that this DrawableSpaceLayer displaysrepeatX - The distance in pixels between horizontal repetitions of
the Drawable. If this is 0 or negative, the Drawable will not repeat
horizontally.repeatY - The distance in pixels between vertical repetitions of
the Drawable. If this is 0 or negative, the Drawable will not repeat
vertically.parallaxX - The number of pixels (in fracunit scale) that the
Drawable moves left for every one fracunit that the camera moves
right, and vice versa. Values between 0 and 1 are appropriate for
backgrounds, and values of at least 1 are appropriate for foregrounds. A
value of 0 will make the Drawable horizontally stationary, and a value of
1 will make it match the SpaceObject layer. Negative values will make the
Drawable look like it is across from the SpaceObject layer on the inside
of a horizontally curved surface.parallaxY - The number of pixels (in fracunit scale) that the
Drawable moves up for every one fracunit that the camera moves
down, and vice versa. Values between 0 and 1 are appropriate for
backgrounds, and values of at least 1 are appropriate for foregrounds. A
value of 0 will make the Drawable vertically stationary, and a value of
1 will make it match the SpaceObject layer. Negative values will make the
Drawable look like it is across from the SpaceObject layer on the inside
of a vertically curved surface.parallaxOriginX - The x position in the SpaceState's space where the
Drawable's origin x-coordinate aligns with the x position of the camera
on the rendering region. If parallaxX is 0, the above description is true
of any x position, and this value is meaningless.parallaxOriginY - The y position in the SpaceState's space where the
Drawable's origin y-coordinate aligns with the y position of the camera
on the rendering region. If parallaxY is 0, the above description is true
of any y position, and this value is meaningless.public final Drawable getDrawable()
