Tilesets are a common technique in game development to create all kinds of tile-based games (from strategy to RPG games).
Here’s a example of simple 2D isometric square tilesets. I decided to use 32×32 pixels tiles and store 10 tiles per row in a single image:
I created a class called public class JGameCanvas that extends from JPanel from swing:
package game;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;
import javax.swing.JPanel;
enum Tile {
GRASS, GRASS_STONE, GRASS_BAGS, T3, T4, T5, T6, T7, T8, T9,
TREE, TREE_CHOMP, TREE_DEAD, T13, T14, T15, T16, T17, T18, T19,
ROAD_H, ROAD_V, ROAD_HV_DOWN, ROAD_HV_UP, ROAD_VH_RIGHT, ROAD_VH_LEFT, ROAD_CROSS, T27, T28, T29,
WALL, WALL_POSTER, WALL_END_RIGHT, WALL_END_LEFT, T34, T35, T36, T37, T38, T39,
T40, T41, T42, T43, T44, T45, T46, T47, T48, T49,
NEWS, T51, RES_1, RES_2, BUSS_1, BUSS_2, HOSP_1, HOSP_2, MARK_1, MARK_2,
PIZZ_1, PIZZ_2, RES_3, RES_4, BUSS_3, BUSS_4, HOSP_3, HOSP_4, MARK_3, MARK_4,
PIZZ_3, PIZZ_4, RES_5, RES_6, BUSS_5, BUSS_6, HOSP_5, HOSP_6, MARK_5, MARK_6
}
public class JGameCanvas extends JPanel{
private static final int tW = 32; // tile width
private static final int tH = 32; // tile height
private static final Tile map[][] =
{{Tile.TREE,Tile.TREE, Tile.TREE, Tile.ROAD_V, Tile.GRASS, Tile.TREE, Tile.TREE_DEAD, Tile.GRASS_STONE, Tile.TREE, Tile.TREE},
{Tile.WALL, Tile.WALL_POSTER, Tile.WALL_END_RIGHT , Tile.ROAD_V, Tile.WALL_END_LEFT, Tile.WALL, Tile.WALL_END_RIGHT, Tile.TREE_CHOMP, Tile.GRASS_STONE, Tile.GRASS_STONE},
{Tile.GRASS,Tile.GRASS, Tile.GRASS_STONE, Tile.ROAD_V, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS},
{Tile.PIZZ_1,Tile.PIZZ_2, Tile.GRASS, Tile.ROAD_V, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS},
{Tile.PIZZ_3,Tile.PIZZ_4, Tile.GRASS, Tile.ROAD_V, Tile.GRASS, Tile.GRASS, Tile.MARK_1, Tile.MARK_2, Tile.HOSP_1, Tile.HOSP_2},
{Tile.ROAD_H,Tile.ROAD_H, Tile.ROAD_H, Tile.ROAD_VH_LEFT, Tile.TREE, Tile.TREE_DEAD, Tile.MARK_3, Tile.MARK_4, Tile.HOSP_3, Tile.HOSP_4},
{Tile.GRASS,Tile.BUSS_1, Tile.BUSS_2, Tile.ROAD_V, Tile.TREE, Tile.NEWS, Tile.MARK_5, Tile.MARK_6, Tile.HOSP_5, Tile.HOSP_6},
{Tile.GRASS,Tile.BUSS_3, Tile.BUSS_4, Tile.ROAD_VH_RIGHT, Tile.ROAD_H, Tile.ROAD_H, Tile.ROAD_H, Tile.ROAD_H, Tile.ROAD_H, Tile.ROAD_H},
{Tile.GRASS,Tile.BUSS_5, Tile.BUSS_6, Tile.ROAD_V, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS},
{Tile.GRASS,Tile.GRASS, Tile.GRASS, Tile.ROAD_V, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS}
};
private Image tileset;
public JGameCanvas() {
tileset = Toolkit.getDefaultToolkit().getImage(this.getClass().getResource("resources/tileset.png"));
}
@Override
protected void paintComponent(Graphics g) {
g.setColor(Color.black);
g.fillRect(0, 0, getWidth(), getHeight());
for(int i=0;i<10;i++)
for(int j=0;j<10;j++)
drawTile(g, map[j][i], i*tW,j*tH);
}
protected void drawTile(Graphics g, Tile t, int x, int y){
// map Tile from the tileset
int mx = t.ordinal()%10;
int my = t.ordinal()/10;
g.drawImage(tileset, x, y, x+tW, y+tH,
mx*tW, my*tH, mx*tW+tW, my*tH+tH, this);
}
}
