com.golden.gamedev.object.background.abstraction.AbstractIsometricBackground
com.golden.gamedev.object.background.IsometricBackground
public class IsometricBackground
The basic isometric background, creates a one layer isometric background.
IsometricBackground
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 isometric background is the basic subclass of
AbstractIsometricBackground
that overrides renderTile
method to draw one layer isometric background :
public void render(Graphics2D g, int tileX, int tileY, int x, int y) { //To create multiple layer, simply subclasstiles
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); } }
AbstractIsometricBackground
and override the renderTile
method to render the tile multiple
times. Isometric background usage example :
IsometricBackground 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 IsometricBackground(tileImages, tiles);

public IsometricBackground(BufferedImage[] tileImages, int[][] tiles, int offsetTileHeight, int startY)
IsometricBackground
with specified tile images,
array of tiles, offset of tile height, and starting y coordinate. The array of tiles that makes up the isometric background tiling, tiles[0][0] = 2 means the tileImages[2] will be drawn on tile 0, 0 coordinate on the map.
The offsetTileHeight
is used to determine the tile image
base tile height, for example the real height of the tile image is 128
but the base height of the tile image is 32, therefore set the
offsetTileHeight
to 96 (128-32).
The startY
is where the isometric background y coordinate is
starting to render, set this startY
value greater than zero
if this background need to be drawn down a bit.
tileImages
- an array of images for the tiletiles
- a two dimensional array that makes up the backgroundoffsetTileHeight
- the tile height offset from the base tile heightstartY
- starting y coordinate to draw this backgroundpublic IsometricBackground(BufferedImage[] tileImages, int[][] tiles)
IsometricBackground
with specified tile images
and array of tiles. The array of tiles that makes up the isometric background tiling, tiles[0][0] = 2 means the tileImages[2] will be drawn on tile 0, 0 coordinate on the map.
tileImages
- an array of images for the tiletiles
- a two dimensional array that makes up the backgroundpublic IsometricBackground(BufferedImage[] tileImages, int horiz, int vert)
IsometricBackground
with specified tile images
as big as horiz
and vert tiles. Generates isometric 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.
tileImages
- an array of images for the tilehoriz
