Class ColorBackground

java.lang.Object
  com.golden.gamedev.object.Background
      com.golden.gamedev.object.background.ColorBackground

All Implemented Interfaces:

Serializable

public class ColorBackground
extends Background

The very basic background type that only fill the background view port with a single color.

This type of background use a fixed memory size. Memory used by small size color background (e.g: 1 x 1) with an extremely large size color background (e.g: 100,000,000 x 100,000,000) is equal.

render

public void render(Graphics2D g,
                   int xbg,
                   int ybg,
                   int x,

Description copied from class: Background

Renders background from specified position and clipping area to specified graphics context.

This method to simplify background subclass rendering, the subclass only need to render the background from specified x, y coordinate with specified clipping area.

For example:

    Background backgr;
    Graphics2D g;

    backgr.render(g, 100, 100,
                  5, 10, 100, 200);
 

Means the background must render itself from background coordinate 100, 100 to specified graphics context, starting from 5, 10 screen pixel as large as 100 x 200 dimension.

Overrides:

render in class Background

Parameters:

g - graphics context

xbg - background x-coordinate

ybg - background y-coordinate

x - screen start x clipping

y - screen start y clipping

w - clipping width

h - clipping height
