All Implemented Interfaces:

Serializable

public class TileBackground
extends AbstractTileBackground

The basic tiling background, creates a one layer background tile.

TileBackground takes up two parameter, the first one is a two dimensional array of integer (int[][] tiles) that makes up the background tiling, and the second one is the tiling image array (BufferedImage[] tileImages).

This tile background is the basic subclass of AbstractTileBackground that overrides renderTile method to draw one layer tile background :

    public void render(Graphics2D g, int tileX, int tileY, int x, int y) {
       // tiles is the two dimensional background tiling
       int tile = tiles[tileX][tileY];

       if (tile >= 0) {
          // tileImages is the tiling images
          g.drawImage(tileImages[tile], x, y, null);
       }
    }
 

To create multiple layer, simply subclass AbstractTileBackground and override the renderTile method to render the tile multiple times.

Tile background usage example :

    TileBackground  background;
    BufferedImage[] tileImages;
    int[][] tiles = new int[40][30]; // 40 x 30 tiling

    // fill tiles with random value
    for (int i=0;i < tiles.length;i++)
    for (int j=0;j < tiles[0].length;j++)
       tiles[i][j] = getRandom(0, tileImages.length-1);

    // create the background
    background = new TileBackground(tileImages, tiles);

Constructor Detail

TileBackground

public TileBackground(BufferedImage[] tileImages,
                      int[][] tiles)

Creates new TileBackground with specified tile images and array of tiles.

The array of tiles that makes up the background tiling, tiles[0][0] = 2 means the tileImages[2] will be drawn on tile 0, 0 coordinate on the map.

Parameters:

tileImages - an array of images for the tile

tiles - a two dimensional array that makes up the background

TileBackground

public TileBackground(BufferedImage[] tileImages,
                      int horiz,
                      int vert)

Creates new TileBackground with specified tile images, as big as horiz, vert tiles.

Generates tile background with tile as big as horiz and vert (tiles = new int[horiz][vert]) and using the first image of the tile images (tileImages[0]) for all the tiles.

Parameters:

tileImages - an array of images for the tile

horiz - total horizontal tiles

vert - total vertical tiles

Method Detail

renderTile

public void renderTile(Graphics2D g,
                       int tileX,
                       int tileY,
                       int x,
                       int y)

Description copied from class: AbstractTileBackground

Renders tile at tileX, tileY position to specified x, y coordinate.

Specified by:

renderTile in class AbstractTileBackground

getTileImages

public BufferedImage[] getTileImages()

Return the tile background tile images.

setTileImages

public void setTileImages(BufferedImage[] tileImages)

Sets the tile background tile images.

getTiles

public int[][] getTiles()

Returns the background tiling.

setTiles

public void setTiles(int[][] tiles)

Sets the background tiling.

This array of tiles that makes up the background tiling, tiles[0][0] = 2 means the tileImages[2] will be drawn on tile 0, 0 coordinate on the map.

setSize

public void setSize(int horiz,
                    int vert)

Description copied from class: AbstractTileBackground

Sets the size of this background (in tiles).

Overrides:

setSize in class AbstractTileBackground

Parameters:

horiz - total background horizontal tiles

vert - total background vertical tiles
